15.6. Command Reference¶
15.6.1. Help¶
Cylc ("silk") is a workflow engine for orchestrating complex
*suites* of inter-dependent distributed cycling (repeating) tasks, as well as
ordinary non-cycling workflows.
For detailed documentation see the Cylc User Guide (cylc doc --help).
Version 7.8.8
The graphical user interface for cylc is "gcylc" (a.k.a. "cylc gui").

% cylc trig SUITE TASK # ditto
% cylc tr SUITE TASK # ditto
% cylc get # Error: ambiguous command
TASK IDENTIFICATION IN CYLC SUITES
Tasks are identified by NAME.CYCLE_POINT where POINT is either a
date-time or an integer.
Date-time cycle points are in an ISO 8601 date-time format, typically
CCYYMMDDThhmm followed by a time zone - e.g. 20101225T0600Z.
Integer cycle points (including those for one-off suites) are integers
- just '1' for one-off suites.

15.6.3. Commands¶
15.6.3.1. 5to6¶
Usage: cylc [prep] 5to6 FILE
Suggest changes to a cylc 5 suite file to make it more cylc 6 compatible.
This may be a suite.rc file, an include file, or a suite.rc.processed file.
By default, print the changed file to stdout. Lines that have been changed
are marked with '# UPGRADE'. These marker comments are purely for your own
information and should not be included in any changes you make. In
particular, they may break continuation lines.
Lines with '# UPGRADE CHANGE' have been altered.
Lines with '# UPGRADE ... INFO' indicate that manual change is needed.
As of cylc 7, 'cylc validate' will no longer print out automatic dependency
section translations. At cylc 6 versions of cylc, 'cylc validate' will show
start-up/mixed async replacement R1* section(s). The validity of these can
be highly dependent on the initial cycle point choice (e.g. whether it is
T00 or T12).
This command works best for hour-based cycling - it will always convert
e.g. 'foo[T-6]' to 'foo[-PT6H]', even where this is in a monthly or yearly
cycling section graph.
This command is an aid, and is not an auto-upgrader or a substitute for
reading the documentation. The suggested changes must be understood and
checked by hand.
Example usage:
# Print out a file path (FILE) with suggested changes to stdout.
cylc 5to6 FILE
# Replace the file with the suggested changes file.
cylc 5to6 FILE > FILE
# Save a copy of the changed file.
cylc 5to6 FILE > FILE.5to6
# Show the diff of the changed file vs the original file.
diff - <(cylc 5to6 FILE) <FILE
Options:
-h, --help Print this help message and exit.
15.6.3.2. broadcast¶
Usage: cylc [control] broadcast|bcast [OPTIONS] REG
Override [runtime] config in targeted namespaces in a running suite.
Uses for broadcast include making temporary changes to task behaviour,
and task-to-downstream-task communication via environment variables.
A broadcast can target any [runtime] namespace for all cycles or for a
specific cycle. If a task is affected by specific-cycle and all-cycle
broadcasts at once, the specific takes precedence. If a task is affected
by broadcasts to multiple ancestor namespaces, the result is determined
by normal [runtime] inheritance. In other words, it follows this order:
all:root -> all:FAM -> all:task -> tag:root -> tag:FAM -> tag:task
Broadcasts persist, even across suite restarts, until they expire when
their target cycle point is older than the oldest current in the suite,
or until they are explicitly cancelled with this command. All-cycle
broadcasts do not expire.
For each task the final effect of all broadcasts to all namespaces is
computed on the fly just prior to job submission. The --cancel and
--clear options simply cancel (remove) active broadcasts, they do not
act directly on the final task-level result. Consequently, for example,
you cannot broadcast to "all cycles except Tn" with an all-cycle
broadcast followed by a cancel to Tn (there is no direct broadcast to Tn
to cancel); and you cannot broadcast to "all members of FAMILY except
member_n" with a general broadcast to FAMILY followed by a cancel to
member_n (there is no direct broadcast to member_n to cancel).
To broadcast a variable to all tasks (quote items with internal spaces):
% cylc broadcast -s "[environment]VERSE = the quick brown fox" REG
To do the same with a file:
% cat >'broadcast.rc' <<'__RC__'
% [environment]
% VERSE = the quick brown fox
% __RC__
% cylc broadcast -F 'broadcast.rc' REG
To cancel the same broadcast:
% cylc broadcast --cancel "[environment]VERSE" REG
If -F FILE was used, the same file can be used to cancel the broadcast:
% cylc broadcast -G 'broadcast.rc' REG
Use -d/--display to see active broadcasts. Multiple --cancel options or
multiple --set and --set-file options can be used on the same command line.
Multiple --set and --set-file options are cumulative.
The --set-file=FILE option can be used when broadcasting multiple values, or
when the value contains newline or other metacharacters. If FILE is "-", read
from standard input.
Broadcast cannot change [runtime] inheritance.
See also 'cylc reload' - reload a modified suite definition at run time.
Arguments:
REG Suite name
Options:
-h, --help show this help message and exit
-p CYCLE_POINT, --point=CYCLE_POINT
Target cycle point. More than one can be added.
Defaults to '*' with --set and --cancel, and nothing
with --clear.
-n NAME, --namespace=NAME
Target namespace. Defaults to 'root' with --set and
--cancel, and nothing with --clear.
-s [SEC]ITEM=VALUE, --set=[SEC]ITEM=VALUE
A [runtime] config item and value to broadcast.
-F FILE, --set-file=FILE, --file=FILE
File with config to broadcast. Can be used multiple
times.
-c [SEC]ITEM, --cancel=[SEC]ITEM
An item-specific broadcast to cancel.
-G FILE, --cancel-file=FILE
File with broadcasts to cancel. Can be used multiple
times.
-C, --clear Cancel all broadcasts, or with -p/--point,
-n/--namespace, cancel all broadcasts to targeted
namespaces and/or cycle points. Use "-C -p '*'" to
cancel all all-cycle broadcasts without canceling all
specific-cycle broadcasts.
-e CYCLE_POINT, --expire=CYCLE_POINT
Cancel any broadcasts that target cycle points earlier
than, but not inclusive of, CYCLE_POINT.
-d, --display Display active broadcasts.
-k TASKID, --display-task=TASKID
Print active broadcasts for a given task
(NAME.CYCLE_POINT).
-b, --box Use unicode box characters with -d, -k.
-r, --raw With -d/--display or -k/--display-task, write out the
broadcast config structure in raw Python form.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
15.6.3.3. cat-log¶
Usage: cylc [info] cat-log|log [OPTIONS] REG [TASK-ID]
Print, view-in-editor, or tail-follow content, print path, or list directory,
of local or remote task job and suite server logs. Batch-system view commands
(e.g. 'qcat') are used if defined in global config and the job is running.
For standard log types use the short-cut option argument or full filename (e.g.
for job stdout "-f o" or "-f job.out" will do).
To list the local job log directory of a remote task, choose "-m l" (directory
list mode) and a local file, e.g. "-f a" (job-activity.log).
If remote job logs are retrieved to the suite host on completion (global config
'[JOB-HOST]retrieve job logs = True') and the job is not currently running, the
local (retrieved) log will be accessed unless '-o/--force-remote' is used.
Custom job logs (written to $CYLC_TASK_LOG_DIR on the job host) are available
from the GUI if listed in 'extra log files' in the suite definition. The file
name must be given here, but can be discovered with '--mode=l' (list-dir).
The correct cycle point format of the suite must be for task job logs.
Note the --host/user options are not needed to view remote job logs. They are
the general command reinvocation options for sites using ssh-based task
messaging.
Arguments:
REG Suite name
[TASK-ID] Task ID
Options:
-h, --help show this help message and exit
-f LOG, --file=LOG Job log: a(job-activity.log), e(job.err), d(job-
edit.diff), j(job), o(job.out), s(job.status),
x(job.xtrace); default o(out). Or <filename> for
custom (and standard) job logs.
-m MODE, --mode=MODE Mode: c(cat), e(edit), d(print-dir), l(list-dir),
p(print), t(tail). Default c(cat).
-r INT, --rotation=INT
Suite log integer rotation number. 0 for current, 1
for next oldest, etc.
-o, --force-remote View remote logs remotely even if they have been
retrieved to the suite host (default False).
-s INT, -t INT, --submit-number=INT, --try-number=INT
Job submit number (default=NN, i.e. latest).
-g, --geditor edit mode: use your configured GUI editor.
--remote-arg=REMOTE_ARGS
(for internal use: continue processing on job host)
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
15.6.3.4. cat-state¶
Usage: cylc [info] cat-state [OPTIONS] REG
Print the suite state in the old state dump file format to stdout.
This command is deprecated; use "cylc ls-checkpoints" instead.
Arguments:
REG Suite name
Options:
-h, --help show this help message and exit
-d, --dump Use the same display format as the 'cylc dump' command.
--user=USER Other user account name. This results in command reinvocation
on the remote account.
--host=HOST Other host name. This results in command reinvocation on the
remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception tracebacks.
15.6.3.5. check-software¶
cylc [admin] check-software [MODULES]
Check for Cylc external software dependencices, including minimum versions.
With no arguments, prints a table of results for all core & optional external
module requirements, grouped by functionality. With module argument(s),
provides an exit status for the collective result of checks on those modules.
Arguments:
[MODULES] Modules to include in the software check, which returns a
zero ('pass') or non-zero ('fail') exit status, where the
integer is equivalent to the number of modules failing. Run
the bare check-software command to view the full list of
valid module arguments (lower-case equivalents accepted).
15.6.3.6. check-triggering¶
cylc [hook] check-triggering ARGS
This is a cylc shutdown event handler that compares the newly generated
suite log with a previously generated reference log "reference.log"
stored in the suite definition directory. Currently it just compares
runtime triggering information, disregarding event order and timing, and
fails the suite if there is any difference. This should be sufficient to
verify correct scheduling of any suite that is not affected by different
run-to-run conditional triggering.
1) run your suite with "cylc run --generate-reference-log" to generate
the reference log with resolved triggering information. Check manually
that the reference run was correct.
2) run reference tests with "cylc run --reference-test" - this
automatically sets the shutdown event handler along with a suite timeout
and "abort if shutdown handler fails", "abort on timeout", and "abort if
any task fails".
Reference tests can use any run mode:
* simulation mode - tests that scheduling is equivalent to the reference
* dummy mode - also tests that task hosting, job submission, job script
evaluation, and cylc messaging are not broken.
* live mode - tests everything (but takes longer with real tasks!)
If any task fails, or if cylc itself fails, or if triggering is not
equivalent to the reference run, the test will abort with non-zero exit
status - so reference tests can be used as automated tests to check
that changes to cylc have not broken your suites.
15.6.3.7. check-versions¶
Usage: cylc [discovery] check-versions [OPTIONS] SUITE
Check the version of cylc invoked on each of SUITE's task host accounts when
CYLC_VERSION is set to *the version running this command line tool*.
Different versions are reported but are not considered an error unless the
-e|--error option is specified, because different cylc versions from 6.0.0
onward should at least be backward compatible.
It is recommended that cylc versions be installed in parallel and access
configured via the cylc version wrapper as described in the cylc INSTALL
file and User Guide. This must be done on suite and task hosts. Users then get
the latest installed version by default, or (like tasks) a particular version
if $CYLC_VERSION is defined.
Use -v/--verbose to see the command invoked to determine the remote version
(all remote cylc command invocations will be of the same form, which may be
site dependent -- see cylc global config documentation.
Arguments:
SUITE Suite name or path
Options:
-h, --help show this help message and exit
-e, --error Exit with error status if 7.8.8 is not available on
all remote accounts.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--suite-owner=OWNER Specify suite owner
-s NAME=VALUE, --set=NAME=VALUE
Set the value of a Jinja2 template variable in the
suite definition. This option can be used multiple
times on the command line. NOTE: these settings
persist across suite restarts, but can be set again on
the "cylc restart" command line if they need to be
overridden.
--set-file=FILE Set the value of Jinja2 template variables in the
suite definition from a file containing NAME=VALUE
pairs (one per line). NOTE: these settings persist
across suite restarts, but can be set again on the
"cylc restart" command line if they need to be
overridden.
15.6.3.8. checkpoint¶
Usage: cylc [control] checkpoint [OPTIONS] REG CHECKPOINT-NAME
Tell suite to checkpoint its current state.
Arguments:
REG Suite name
CHECKPOINT-NAME Checkpoint name
Options:
-h, --help show this help message and exit
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
15.6.3.9. client¶
Usage: cylc client [OPTIONS] METHOD [REG]
(This command is for internal use.)
Invoke HTTP(S) client, expect JSON from STDIN for keyword arguments.
Use the -n option if client function requires no keyword arguments.
Arguments:

tracebacks.
15.6.3.12. diff¶
Usage: cylc [prep] diff|compare [OPTIONS] SUITE1 SUITE2
Compare two suite definitions and display any differences.
Differencing is done after parsing the suite.rc files so it takes
account of default values that are not explicitly defined, it disregards
the order of configuration items, and it sees any include-file content
after inlining has occurred.
Files in the suite bin directory and other sub-directories of the
suite definition directory are not currently differenced.
Arguments:
SUITE1 Suite name or path
SUITE2 Suite name or path
Options:
-h, --help show this help message and exit
-n, --nested print suite.rc section headings in nested form.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--suite-owner=OWNER Specify suite owner
-s NAME=VALUE, --set=NAME=VALUE
Set the value of a Jinja2 template variable in the
suite definition. This option can be used multiple
times on the command line. NOTE: these settings
persist across suite restarts, but can be set again on
the "cylc restart" command line if they need to be
overridden.
--set-file=FILE Set the value of Jinja2 template variables in the
suite definition from a file containing NAME=VALUE
pairs (one per line). NOTE: these settings persist
across suite restarts, but can be set again on the
"cylc restart" command line if they need to be
overridden.
--initial-cycle-point=CYCLE_POINT, --initial-point=CYCLE_POINT, --icp=CYCLE_POINT, --ict=CYCLE_POINT
Set the initial cycle point. Required if not defined
in suite.rc.
15.6.3.13. documentation¶
Usage: cylc [info] documentation|browse [OPTIONS] [TARGET]
View documentation in the browser, as per Cylc global config.
% cylc doc [OPTIONS]
View local or internet [--www] Cylc documentation URLs.
% cylc doc [-t TASK] SUITE
View suite or task documentation, if URLs are specified in the suite. This
parses the suite definition to extract the requested URL. Note that suite
server programs also hold suite URLs for access from the Cylc GUI.
Arguments:
[TARGET] File or suite name
Options:
-h, --help show this help message and exit
-g, --guides Open the HTML (User & Suite Design) Guides directly.
-w, --www Open the cylc internet homepage
-t TASK_NAME, --task=TASK_NAME
Browse task documentation URLs.
-s, --stdout Just print the URL to stdout.
--debug Print exception traceback on error.
--url=URL URL to view in your configured browser.
-v, --verbose Verbose output mode.
15.6.3.14. dump¶
Usage: cylc [info] dump [OPTIONS] REG
Print state information (e.g. the state of each task) from a running
suite. For small suites 'watch cylc [info] dump SUITE' is an effective
non-GUI real time monitor (but see also 'cylc monitor').
For more information about a specific task, such as the current state of
its prerequisites and outputs, see 'cylc [info] show'.
Examples:
Display the state of all running tasks, sorted by cycle point:
% cylc [info] dump --tasks --sort SUITE | grep running
Display the state of all tasks in a particular cycle point:
% cylc [info] dump -t SUITE | grep 2010082406
Arguments:
REG Suite name
Options:
-h, --help show this help message and exit
-g, --global Global information only.
-t, --tasks Task states only.
-r, --raw, --raw-format
Display raw format.
-s, --sort Task states only; sort by cycle point instead of name.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
15.6.3.15. edit¶
Usage: cylc [prep] edit [OPTIONS] SUITE
Edit suite definitions without having to move to their directory
locations, and with optional reversible inlining of include-files. Note
that Jinja2 suites can only be edited in raw form but the processed
version can be viewed with 'cylc [prep] view -p'.
1/cylc [prep] edit SUITE
Change to the suite definition directory and edit the suite.rc file.
2/ cylc [prep] edit -i,--inline SUITE
Edit the suite with include-files inlined between special markers. The
original suite.rc file is temporarily replaced so that the inlined
version is "live" during editing (i.e. you can run suites during
editing and cylc will pick up changes to the suite definition). The
inlined file is then split into its constituent include-files
again when you exit the editor. Include-files can be nested or
multiply-included; in the latter case only the first inclusion is
inlined (this prevents conflicting changes made to the same file).
3/ cylc [prep] edit --cleanup SUITE
Remove backup files left by previous INLINED edit sessions.
INLINED EDITING SAFETY: The suite.rc file and its include-files are
automatically backed up prior to an inlined editing session. If the
editor dies mid-session just invoke 'cylc edit -i' again to recover from
the last saved inlined file. On exiting the editor, if any of the
original include-files are found to have changed due to external
intervention during editing you will be warned and the affected files
will be written to new backups instead of overwriting the originals.
Finally, the inlined suite.rc file is also backed up on exiting
the editor, to allow recovery in case of accidental corruption of the
include-file boundary markers in the inlined file.
The edit process is spawned in the foreground as follows:
% <editor> suite.rc
Where <editor> is defined in the cylc site/user config files.
See also 'cylc [prep] view'.
Arguments:
SUITE Suite name or path
Options:
-h, --help show this help message and exit
-i, --inline Edit with include-files inlined as described above.
--cleanup Remove backup files left by previous inlined edit
sessions.
-g, --gui Force use of the configured GUI editor.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--suite-owner=OWNER Specify suite owner
15.6.3.16. email-suite¶
Usage: cylc [hook] email-suite EVENT SUITE MESSAGE
THIS COMMAND IS OBSOLETE - use built-in email event hooks.
This is a simple suite event hook script that sends an email.
The command line arguments are supplied automatically by cylc.
For example, to get an email alert when a suite shuts down:
# SUITE.RC
[cylc]
[[environment]]
MAIL_ADDRESS = foo@bar.baz.waz
[[events]]
shutdown handler = cylc email-suite
See the Suite.rc Reference (Cylc User Guide) for more information
on suite and task event hooks and event handler scripts.
15.6.3.17. email-task¶
Usage: cylc [hook] email-task EVENT SUITE TASKID MESSAGE
THIS COMMAND IS OBSOLETE - use built-in email event hooks.
A simple task event hook handler script that sends an email.
The command line arguments are supplied automatically by cylc.
For example, to get an email alert whenever any task fails:
# SUITE.RC
[cylc]
[[environment]]
MAIL_ADDRESS = foo@bar.baz.waz
[runtime]
[[root]]
[[[events]]]
failed handler = cylc email-task
See the Suite.rc Reference (Cylc User Guide) for more information
on suite and task event hooks and event handler scripts.
15.6.3.18. ext-trigger¶
Usage: cylc [control] ext-trigger [OPTIONS] REG MSG ID
Report an external event message to a suite server program. It is expected that
a task in the suite has registered the same message as an external trigger - a
special prerequisite to be satisifed by an external system, via this command,
rather than by triggering off other tasks.
The ID argument should uniquely distinguish one external trigger event from the
next. When a task's external trigger is satisfied by an incoming message, the
message ID is broadcast to all downstream tasks in the cycle point as
$CYLC_EXT_TRIGGER_ID so that they can use it - e.g. to identify a new data file
that the external triggering system is responding to.
Use the retry options in case the target suite is down or out of contact.
The suite passphrase must be installed in $HOME/.cylc/<SUITE>/.
Note: to manually trigger a task use 'cylc trigger', not this command.
Arguments:
REG Suite name
MSG External trigger message
ID Unique trigger ID

tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.

3/ cylc [prep] graph [OPTIONS] --reference SUITE [START[STOP]]
Print out a reference format for the dependencies in SUITE.
4/ cylc [prep] graph [OPTIONS] --output-file FILE SUITE
Plot SUITE dependencies to a file FILE with a extension-derived format.
If FILE endswith ".png", output in PNG format, etc.
Plot suite dependency graphs in an interactive graph viewer, or (with
"--output-file") directly to image file.
See also "cylc ref-graph" to generate the plain text "reference" graph format
without the need for PyGTK to be installed.
If START is given it overrides "[visualization] initial cycle point" to
determine the start point of the graph, which defaults to the suite initial
cycle point. If STOP is given it overrides "[visualization] final cycle point"
to determine the end point of the graph, which defaults to the graph start
point plus "[visualization] number of cycle points" (which defaults to 3).
The graph start and end points are adjusted up and down to the suite initial
and final cycle points, respectively, if necessary.
The "Save" button generates an image of the current view, of format (e.g. png,
svg, jpg, eps) determined by the filename extension. If the chosen format is
not available a dialog box will show those that are available.
If the optional output filename is specified, the viewer will not open and a
graph will be written directly to the file.
GRAPH VIEWER CONTROLS:
* Center on a node: left-click.
* Pan view: left-drag.
* Zoom: +/- buttons, mouse-wheel, or ctrl-left-drag.
* Box zoom: shift-left-drag.

suite definition. This option can be used multiple
times on the command line. NOTE: these settings
persist across suite restarts, but can be set again on
the "cylc restart" command line if they need to be
overridden.
--set-file=FILE Set the value of Jinja2 template variables in the
suite definition from a file containing NAME=VALUE
pairs (one per line). NOTE: these settings persist
across suite restarts, but can be set again on the
"cylc restart" command line if they need to be
overridden.
15.6.3.29. graph-diff¶
Usage: cylc graph-diff [OPTIONS] SUITE1 SUITE2 -- [GRAPH_OPTIONS_ARGS]
Difference 'cylc graph --reference' output for SUITE1 and SUITE2.
OPTIONS: Use '-g' to launch a graphical diff utility.

SUITE1, SUITE2: Suite names to compare.
GRAPH_OPTIONS_ARGS: Options and arguments passed directly to cylc graph.
15.6.3.30. gscan¶
Usage: cylc gscan [OPTIONS]
This is the cylc scan gui for monitoring running suites on a set of
hosts.
To customize themes copy $CYLC_DIR/etc/gcylc.rc.eg to ~/.cylc/gcylc.rc and
follow the instructions in the file.
Arguments:
[HOSTS ...] Hosts to scan instead of the configured hosts.
Options:
-h, --help show this help message and exit
-a, --all Scan all port ranges in known hosts.
-n PATTERN, --name=PATTERN
List suites with name matching PATTERN (regular
expression). Defaults to any name. Can be used
multiple times.
-o PATTERN, --suite-owner=PATTERN
List suites with owner matching PATTERN (regular
expression). Defaults to just your own suites. Can be
used multiple times.
--comms-timeout=SEC Set a timeout for network connections to each running
suite. The default is 5 seconds.
--interval=SECONDS Time interval (in seconds) between full updates
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
15.6.3.31. gui¶
Usage: cylc gui [OPTIONS] [REG] [USER_AT_HOST]
gcylc [OPTIONS] [REG] [USER_AT_HOST]
This is the cylc Graphical User Interface.
The USER_AT_HOST argument allows suite selection by 'cylc scan' output:
cylc gui $(cylc scan | grep <suite_name>)
Local suites can be opened and switched between from within gcylc. To connect
to running remote suites (whose passphrase you have installed) you must
currently use --host and/or --user on the gcylc command line.
Available task state color themes are shown under the View menu. To customize
themes copy <cylc-dir>/etc/gcylc.rc.eg to ~/.cylc/gcylc.rc and follow the
instructions in the file.
To see current configuration settings use "cylc get-gui-config".
In the graph view, View -> Options -> "Write Graph Frames" writes .dot graph
files to the suite share directory (locally, for a remote suite). These can
be processed into a movie by $CYLC_DIR/dev/bin/live-graph-movie.sh=.
Arguments:
[REG] Suite name
[USER_AT_HOST] user@host:port, shorthand for --user, --host & --port.
Options:
-h, --help show this help message and exit
-r, --restricted Restrict display to 'active' task states: submitted,
submit-failed, submit-retrying, running, failed,
retrying; and disable the graph view. This may be
needed for very large suites. The state summary icons
in the status bar still represent all task proxies.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is

suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-s NAME=VALUE, --set=NAME=VALUE
Set the value of a Jinja2 template variable in the
suite definition. This option can be used multiple
times on the command line. NOTE: these settings
persist across suite restarts, but can be set again on
the "cylc restart" command line if they need to be
overridden.
--set-file=FILE Set the value of Jinja2 template variables in the
suite definition from a file containing NAME=VALUE
pairs (one per line). NOTE: these settings persist
across suite restarts, but can be set again on the
"cylc restart" command line if they need to be
overridden.
15.6.3.32. hold¶
Usage: cylc [control] hold [OPTIONS] REG [TASK_GLOB ...]
Hold a suite or tasks:
cylc hold REG - hold a suite
cylc hold REG TASK_GLOB ... - hold one or more tasks in a suite
Held tasks do not submit their jobs even if ready to run.
See also 'cylc [control] release'.
Multiple TASK_GLOBs can be given. They each match task proxy instances in the
current task pool by task or family name pattern, cycle point pattern, and task
state. They do NOT match any task at any point in the abstract suite graph; if
target task instances do not exist in the current pool you must insert them
first with the "cylc insert" command.
* [CYCLE-POINT-GLOB/]TASK-NAME-GLOB[:TASK-STATE]
* [CYCLE-POINT-GLOB/]FAMILY-NAME-GLOB[:TASK-STATE]
* TASK-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
* FAMILY-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
For example, to match:
* all tasks in a cycle: '20200202T0000Z/*' or '*.20200202T0000Z'
* all tasks in the submitted status: ':submitted'
* retrying 'foo*' tasks in 0000Z cycles: 'foo*.*0000Z:retrying' or
'*0000Z/foo*:retrying'
* retrying tasks in 'BAR' family: '*/BAR:retrying' or 'BAR.*:retrying'
* retrying tasks in 'BAR' or 'BAZ' families: '*/BA[RZ]:retrying' or
'BA[RZ].*:retrying'
The old 'MATCH POINT' syntax will be automatically detected and supported. To
avoid this, use the '--no-multitask-compat' option, or use the new syntax
(with a '/' or a '.') when specifying 2 TASK_GLOB arguments.
Arguments:
REG Suite name
[TASK_GLOB ...] Task match pattern(s)
Options:
-h, --help show this help message and exit
--after=CYCLE_POINT Hold whole suite AFTER this cycle point.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is

suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
-m, --family (Obsolete) This option is now ignored and is retained
for backward compatibility only. TASK_GLOB in the
argument list can be used to match task and family
names regardless of this option.
--no-multitask-compat
Disallow backward compatible multitask interface.
15.6.3.33. import-examples¶
Usage: cylc import-examples DIR
Copy the cylc example suites to DIR and register them for use under the GROUP
suite name group.
Arguments:
DIR destination directory
15.6.3.34. insert¶
Usage: cylc [control] insert [OPTIONS] TASK_GLOB [...]
Insert new task proxies into the task pool of a running suite, e.g. to allow
re-triggering of an earlier task that has already been removed from the pool.
NOTE: inserted cycling tasks cycle on as normal, even if another instance of
the same task exists at a later cycle (instances of the same task at different
cycles can coexist, but a newly spawned task will not be added to the pool if
it catches up to another task with the same ID).
See also 'cylc submit', for running tasks independently of the scheduler.
TASK_GLOB matches task or family names, to insert task instances into the pool
at a specific given cycle point. (NOTE this differs from other commands which
match name and cycle point patterns against instances already in the pool).
* CYCLE-POINT/TASK-NAME-GLOB
* CYCLE-POINT/FAMILY-NAME-GLOB
* TASK-NAME-GLOB.CYCLE-POINT
* FAMILY-NAME-GLOB.CYCLE-POINT
For example, to match, within the given cycle point (e.g. '20200202T0000Z'):
* all tasks: '20200202T0000Z/*' or '*.20200202T0000Z'
* all tasks named model_N for some character N: '20200202T0000Z/model_?' or
'model_?.20200202T0000Z'
* all tasks in 'BAR' family: '20200202T0000Z/BAR' or 'BAR.20200202T0000Z'
* all tasks in 'BAR' or 'BAZ' families: '20200202T0000Z/BA[RZ]' or
'BA[RZ].20200202T0000Z'
The old 'MATCH POINT' syntax will be automatically detected and supported. To
avoid this, use the '--no-multitask-compat' option, or use the new syntax
(with a '/' or a '.') when specifying 2 TASK_GLOB arguments.

commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.

times on the command line. NOTE: these settings
persist across suite restarts, but can be set again on
the "cylc restart" command line if they need to be
overridden.
--set-file=FILE Set the value of Jinja2 template variables in the
suite definition from a file containing NAME=VALUE
pairs (one per line). NOTE: these settings persist
across suite restarts, but can be set again on the

time and events. Otherwise, display the latest and/or the checkpoints of suite
parameters, task pool and broadcast states in the suite runtime database.
Arguments:
REG Suite name
[ID ...] Checkpoint ID (default=latest)
Options:
-h, --help show this help message and exit
-a, --all Display data of all available checkpoints.
--user=USER Other user account name. This results in command reinvocation
on the remote account.
--host=HOST Other host name. This results in command reinvocation on the
remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception tracebacks.
15.6.3.42. message¶
Usage: cylc [task] message [OPTIONS] -- [REG] [TASK-JOB] [[SEVERITY:]MESSAGE ...]
Record task job messages.
Send task job messages to:
- The job stdout/stderr.
- The job status file, if there is one.
- The suite server program, if communication is possible.
Task jobs use this command to record and report status such as success and
failure. Applications run by task jobs can use this command to report messages
and to report registered task outputs.
Messages can be specified as arguments. A '-' indicates that the command should
read messages from STDIN. When reading from STDIN, multiple messages are
separated by empty lines. Examples:
Single message as an argument:
% cylc message -- "${CYLC_SUITE_NAME}" "${CYLC_TASK_JOB}" 'Hello world!'
Multiple messages as arguments:
% cylc message -- "${CYLC_SUITE_NAME}" "${CYLC_TASK_JOB}" \
'Hello world!' 'Hi' 'WARNING:Hey!'
Multiple messages on STDIN:
% cylc message -- "${CYLC_SUITE_NAME}" "${CYLC_TASK_JOB}" - <<'__STDIN__'
% Hello
% world!
%
% Hi
%
% WARNING:Hey!
%__STDIN__
Note "${CYLC_SUITE_NAME}" and "${CYLC_TASK_JOB}" are made available in task job
environments - you do not need to write their actual values in task scripting.
Each message can be prefixed with a severity level using the syntax 'SEVERITY:
MESSAGE'.
The default message severity is INFO. The --severity=SEVERITY option can be
used to set the default severity level for all unprefixed messages.
Note: to abort a job script with a custom error message, use cylc__job_abort:
cylc__job_abort 'message...'
(For technical reasons this is a shell function, not a cylc sub-command.)
For backward compatibility, if number of arguments is less than or equal to 2,
the command assumes the classic interface, where all arguments are messages.
Otherwise, the first 2 arguments are assumed to be the suite name and the task
job identifier.
Arguments:
[REG] Suite name
[TASK-JOB] Task job identifier CYCLE/TASK_NAME/SUBMIT_NUM
[[SEVERITY:]MESSAGE ...] Messages
Options:
-h, --help show this help message and exit
-s SEVERITY, -p SEVERITY, --severity=SEVERITY, --priority=SEVERITY
Set severity levels for messages that do not have one

to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
15.6.3.43. monitor¶
Usage: cylc [info] monitor [OPTIONS] REG [USER_AT_HOST]

--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
15.6.3.44. nudge¶
Usage: cylc [control] nudge [OPTIONS] REG
Cause the cylc task processing loop to be invoked in a running suite.
This happens automatically when the state of any task changes such that
task processing (dependency negotation etc.) is required, or if a
clock-trigger task is ready to run.
The main reason to use this command is to update the "estimated time till
completion" intervals shown in the tree-view suite control GUI, during
periods when nothing else is happening.
Arguments:
REG Suite name
Options:
-h, --help show this help message and exit
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
15.6.3.45. ping¶
Usage: cylc [discovery] ping [OPTIONS] REG [TASK]
If suite REG is running or TASK in suite REG is currently running,
exit with success status, else exit with error status.
Arguments:
REG Suite name
[TASK] Task NAME.CYCLE_POINT
Options:
-h, --help show this help message and exit
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
15.6.3.46. poll¶
Usage: cylc [control] poll [OPTIONS] REG [TASK_GLOB ...]
Poll (query) task jobs to verify and update their statuses.
cylc poll REG - poll all active tasks
cylc poll REG TASK_GLOB ... - poll multiple active tasks or families
Multiple TASK_GLOBs can be given. They each match task proxy instances in the
current task pool by task or family name pattern, cycle point pattern, and task
state. They do NOT match any task at any point in the abstract suite graph; if
target task instances do not exist in the current pool you must insert them
first with the "cylc insert" command.
* [CYCLE-POINT-GLOB/]TASK-NAME-GLOB[:TASK-STATE]
* [CYCLE-POINT-GLOB/]FAMILY-NAME-GLOB[:TASK-STATE]
* TASK-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
* FAMILY-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
For example, to match:
* all tasks in a cycle: '20200202T0000Z/*' or '*.20200202T0000Z'
* all tasks in the submitted status: ':submitted'
* retrying 'foo*' tasks in 0000Z cycles: 'foo*.*0000Z:retrying' or
'*0000Z/foo*:retrying'
* retrying tasks in 'BAR' family: '*/BAR:retrying' or 'BAR.*:retrying'
* retrying tasks in 'BAR' or 'BAZ' families: '*/BA[RZ]:retrying' or
'BA[RZ].*:retrying'
The old 'MATCH POINT' syntax will be automatically detected and supported. To
avoid this, use the '--no-multitask-compat' option, or use the new syntax
(with a '/' or a '.') when specifying 2 TASK_GLOB arguments.
Arguments:
REG Suite name
[TASK_GLOB ...] Task match pattern(s)
Options:
-h, --help show this help message and exit
-s, --succeeded Allow polling of succeeded tasks.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
-m, --family (Obsolete) This option is now ignored and is retained
for backward compatibility only. TASK_GLOB in the
argument list can be used to match task and family
names regardless of this option.
--no-multitask-compat
Disallow backward compatible multitask interface.
15.6.3.47. print¶
Usage: cylc [prep] print [OPTIONS] [REGEX]
Print registered (installed) suites.
Note on result filtering:
(a) The filter patterns are Regular Expressions, not shell globs, so
the general wildcard is '.*' (match zero or more of anything), NOT '*'.
(b) For printing purposes there is an implicit wildcard at the end of
each pattern ('foo' is the same as 'foo/*'); use the string end marker
to prevent this ('foo$' matches only literal 'foo').
Arguments:
[REGEX] Suite name regular expression pattern
Options:
-h, --help show this help message and exit
-t, --tree Print suites in nested tree form.
-b, --box Use unicode box drawing characters in tree views.
-a, --align Align columns.
-x don't print suite definition directory paths.
-y Don't print suite titles.
--fail Fail (exit 1) if no matching suites are found.
--user=USER Other user account name. This results in command reinvocation
on the remote account.
--host=HOST Other host name. This results in command reinvocation on the
remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception tracebacks.
15.6.3.48. profile-battery¶
Usage: cylc profile-battery [-e [EXPERIMENT ...]] [-v [VERSION ...]]
Run profiling experiments against different versions of cylc. A list of
experiments can be specified after the -e flag, if not provided the experiment
"complex" will be chosen. A list of versions to profile against can be
specified after the -v flag, if not provided the current version will be used.
Experiments are stored in etc/profile-experiments, user experiments can be
stored in .profiling/experiments. Experiments are specified without the file
extension, experiments in .profiling/ will be chosen before those in etc/.
IMPORTANT: See etc/profile-experiments/example for an experiment template with
further details.
Versions are any valid git identifiers i.e. tags, branches, commits. To compare
results to different cylc versions either:
* Supply cylc profile-battery with a complete list of the versions you wish
to profile, it will then provide the option to checkout the required
versions automatically.
* Checkout each version manually running cylc profile-battery against only
one version at a time. Once all results have been gathered you can then
run cylc profile-battery with a complete list of versions.
Profiling will save results to .profiling/results.json where they can be used
for future comparisons. To list profiling results run:
* cylc profile-battery --ls # list all results
* cylc profile-battery --ls -e experiment # list all results for
# experiment "experiment".
* cylc profile-battery --ls --delete -v 6.1.2 # Delete all results for
# version 6.1.2 (prompted).
If matplotlib and numpy are installed profiling generates plots which are
saved to .profiling/plots or presented in an interactive window using the -i
flag.
Results are stored along with a checksum for the experiment file. When an
experiment file is changed previous results are maintained, future results will
be stored separately. To copy results from an older version of an experiment
into those from the current one run:
* cylc profile-battery --promote experiment@checksum
NOTE: At present results cannot be analysed without the experiment file so old
results must be "copied" in this way to be re-used.
The results output contain only a small number of metrics, to see a full list
of results use the --full option.
Options:
-h, --help show this help message and exit
-e, --experiments Specify list of experiments to run.
-v, --versions Specify cylc versions to profile. Git tags, branches,
commits are all valid.
-i, --interactive Open any plots in interactive window rather saving
them to files.
-p, --no-plots Don't generate any plots.
--ls, --list-results List all stored results. Experiments and versions to
list can be specified using --experiments and
--versions.
--delete Delete stored results (to be used in combination with
--list-results).
-y, --yes Answer yes to any user input. Will check-out cylc
versions as required.
--full-results, --full
Display all gathered metrics.
--lobf-order=LOBF_ORDER
The order (int)of the line of best fit to be drawn. 0
for no lobf, 1 for linear, 2 for quadratic ect.
--promote=PROMOTE Promote results from an older version of an experiment
to the current version. To be used when making non-
functional changes to an experiment.
--test For development purposes, run experiment without
saving results and regardless of any prior runs.
15.6.3.49. ref-graph¶
Usage: Usage:
cylc ref-graph SUITE [START] [STOP]
Implement the old ``cylc graph --reference command`` for producing a
text-format representation of a suite graph.
The `--reference` flag is optional here.
THIS IS A BACK-PORT OF the Python 3 bin/cylc-graph FOR CYLC 8, TO GENERATE
TEXT-FORMAT "REFERENCE GRAPHS" WITHOUT THE NEED FOR PYGTK TO BE INSTALLED.
Arguments:
[SUITE] Suite name or path
[START] Initial cycle point (default: suite initial point)
[STOP] Final cycle point (default: initial + 3 points)
Options:
-h, --help show this help message and exit
-u, --ungrouped Start with task families ungrouped (the default is
grouped).
-n, --namespaces Plot the suite namespace inheritance hierarchy (task
run time properties).
-r, --reference Output in a sorted plain text format for comparison
purposes.
--show-suicide Show suicide triggers. They are not shown by default,
unless toggled on with the tool bar button.
--icp=CYCLE_POINT Set initial cycle point. Required if not defined in
suite.rc.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--suite-owner=OWNER Specify suite owner
-s NAME=VALUE, --set=NAME=VALUE
Set the value of a Jinja2 template variable in the
suite definition. This option can be used multiple
times on the command line. NOTE: these settings
persist across suite restarts, but can be set again on
the "cylc restart" command line if they need to be
overridden.
--set-file=FILE Set the value of Jinja2 template variables in the
suite definition from a file containing NAME=VALUE
pairs (one per line). NOTE: these settings persist
across suite restarts, but can be set again on the
"cylc restart" command line if they need to be
overridden.
15.6.3.50. register¶
Usage: cylc [prep] register [OPTIONS] [REG] [PATH]
Register the name REG for the suite definition in PATH. The suite server
program can then be started, stopped, and targeted by name REG. (Note that
"cylc run" can also register suites on the fly).
Registration creates a suite run directory "~/cylc-run/REG/" containing a
".service/source" symlink to the suite definition location. The .service
directory is also used for server authentication files at runtime. With the
"--run-dir" option "~/cylc-run/REG" can be symlinked to another location.
Suite names can be hierarchical, corresponding to path under the run directory.
% cylc register dogs/fido PATH
Register PATH/suite.rc as dogs/fido, with run directory ~/cylc-run/dogs/fido.
% cylc register dogs/fido
Register $PWD/suite.rc as dogs/fido.
% cylc register
Register $PWD/suite.rc as the parent directory name: $(basename $PWD).
The same suite can be registered with multiple names; this results in multiple
suite run directories that link to the same suite definition.
To "unregister" a suite, delete or rename its run directory (renaming it under
~/cylc-run effectively re-registers the original suite with the new name).
Use of "--redirect" is required to allow an existing name (and run directory)
to be associated with a different suite definition. This is potentially
dangerous because the new suite will overwrite files in the existing run
directory. You should consider deleting or renaming an existing run directory
rather than just re-use it with another suite.
Arguments:
[REG] Suite name
[PATH] Suite definition directory (defaults to $PWD)
Options:
-h, --help show this help message and exit
--redirect Allow an existing suite name and run directory to be used
with another suite.
--run-dir=RUNDIR Symlink $HOME/cylc-run/REG to RUNDIR/REG.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation on
the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
15.6.3.51. release¶
Usage: cylc [control] release|unhold [OPTIONS] REG [TASK_GLOB ...]
Release a held suite or tasks.
cylc release REG - release the suite
cylc release REG TASK_GLOB ... - release one or more tasks
Held tasks do not submit their jobs even if ready to run.
See also 'cylc [control] hold'.
Multiple TASK_GLOBs can be given. They each match task proxy instances in the
current task pool by task or family name pattern, cycle point pattern, and task
state. They do NOT match any task at any point in the abstract suite graph; if
target task instances do not exist in the current pool you must insert them
first with the "cylc insert" command.
* [CYCLE-POINT-GLOB/]TASK-NAME-GLOB[:TASK-STATE]
* [CYCLE-POINT-GLOB/]FAMILY-NAME-GLOB[:TASK-STATE]
* TASK-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
* FAMILY-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
For example, to match:
* all tasks in a cycle: '20200202T0000Z/*' or '*.20200202T0000Z'
* all tasks in the submitted status: ':submitted'
* retrying 'foo*' tasks in 0000Z cycles: 'foo*.*0000Z:retrying' or
'*0000Z/foo*:retrying'
* retrying tasks in 'BAR' family: '*/BAR:retrying' or 'BAR.*:retrying'
* retrying tasks in 'BAR' or 'BAZ' families: '*/BA[RZ]:retrying' or
'BA[RZ].*:retrying'
The old 'MATCH POINT' syntax will be automatically detected and supported. To
avoid this, use the '--no-multitask-compat' option, or use the new syntax
(with a '/' or a '.') when specifying 2 TASK_GLOB arguments.
Arguments:
REG Suite name
[TASK_GLOB ...] Task match pattern(s)
Options:
-h, --help show this help message and exit
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
-m, --family (Obsolete) This option is now ignored and is retained
for backward compatibility only. TASK_GLOB in the
argument list can be used to match task and family
names regardless of this option.
--no-multitask-compat
Disallow backward compatible multitask interface.
15.6.3.52. reload¶
Usage: cylc [control] reload [OPTIONS] REG
Tell a suite to reload its definition at run time. All settings
including task definitions, with the exception of suite log
configuration, can be changed on reload. Note that defined tasks can be
be added to or removed from a running suite with the 'cylc insert' and
'cylc remove' commands, without reloading. This command also allows
addition and removal of actual task definitions, and therefore insertion
of tasks that were not defined at all when the suite started (you will
still need to manually insert a particular instance of a newly defined
task). Live task proxies that are orphaned by a reload (i.e. their task
definitions have been removed) will be removed from the task pool if
they have not started running yet. Changes to task definitions take
effect immediately, unless a task is already running at reload time.
If the suite was started with Jinja2 template variables set on the
command line (cylc run --set FOO=bar REG) the same template settings
apply to the reload (only changes to the suite.rc file itself are
reloaded).
If the modified suite definition does not parse, failure to reload will
be reported but no harm will be done to the running suite.
Arguments:
REG Suite name
Options:
-h, --help show this help message and exit
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
15.6.3.53. remote-init¶
Usage: cylc [task] remote-init [--indirect-comm=ssh] UUID RUND
(This command is for internal use.)
Install suite service files on a task remote (i.e. a [owner@]host):
.service/contact: All task -> suite communication methods.

15.6.3.55. remove¶
Usage: cylc [control] remove [OPTIONS] REG TASK_GLOB [...]
Remove one or more task instances from a running suite.
Tasks will be forced to spawn successors before removal if they have not done
so already, unless you use '--no-spawn'.
Multiple TASK_GLOBs can be given. They each match task proxy instances in the
current task pool by task or family name pattern, cycle point pattern, and task
state. They do NOT match any task at any point in the abstract suite graph; if
target task instances do not exist in the current pool you must insert them
first with the "cylc insert" command.
* [CYCLE-POINT-GLOB/]TASK-NAME-GLOB[:TASK-STATE]
* [CYCLE-POINT-GLOB/]FAMILY-NAME-GLOB[:TASK-STATE]
* TASK-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
* FAMILY-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]

--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.

for backward compatibility only. TASK_GLOB in the
argument list can be used to match task and family
names regardless of this option.
--no-multitask-compat
Disallow backward compatible multitask interface.
15.6.3.56. report-timings¶
Usage: cylc [util] report-timings [OPTIONS] REG
Retrieve suite timing information for wait and run time performance analysis.
Raw output and summary output (in text or HTML format) are available. Output
is sent to standard output, unless an output filename is supplied.
Summary Output (the default):
Data stratified by host and batch system that provides a statistical
summary of
1. Queue wait time (duration between task submission and start times)
2. Task run time (duration between start and succeed times)
3. Total run time (duration between task submission and succeed times)
Summary tables can be output in plain text format, or HTML with embedded SVG
boxplots. Both summary options require the Pandas library, and the HTML
summary option requires the Matplotlib library.
Raw Output:
A flat list of tabular data that provides (for each task and cycle) the
1. Time of successful submission
2. Time of task start
3. Time of task successful completion
as well as information about the batch system and remote host to permit
stratification/grouping if desired by downstream processors.
Timings are shown only for succeeded tasks.
For long-running and/or large suites (i.e. for suites with many task events),
the database query to obtain the timing information may take some time.
Arguments:
REG Suite name
Options:
-h, --help show this help message and exit
-r, --raw Show raw timing output suitable for custom
diagnostics.
-s, --summary Show textual summary timing output for tasks.
-w, --web-summary Show HTML summary timing output for tasks.
-O OUTPUT_FILENAME, --output-file=OUTPUT_FILENAME
Output to a specific file
--user=USER Other user account name. This results in command
reinvocation on the remote account.

cylc reset --state=xxx REG - reset all tasks to state xxx
cylc reset --state=xxx REG TASK_GLOB ... - reset one or more tasks to xxx
Outputs are automatically updated to reflect the new task state, except for
custom message outputs which can be manipulated directly with "--output".
Prerequisites reflect the state of other tasks; they are not changed except
to unset them on resetting state to 'waiting' or earlier.
To hold and release tasks use "cylc hold" and "cylc release", not this command.
Multiple TASK_GLOBs can be given. They each match task proxy instances in the
current task pool by task or family name pattern, cycle point pattern, and task
state. They do NOT match any task at any point in the abstract suite graph; if
target task instances do not exist in the current pool you must insert them
first with the "cylc insert" command.
* [CYCLE-POINT-GLOB/]TASK-NAME-GLOB[:TASK-STATE]
* [CYCLE-POINT-GLOB/]FAMILY-NAME-GLOB[:TASK-STATE]
* TASK-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
* FAMILY-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
For example, to match:
* all tasks in a cycle: '20200202T0000Z/*' or '*.20200202T0000Z'
* all tasks in the submitted status: ':submitted'
* retrying 'foo*' tasks in 0000Z cycles: 'foo*.*0000Z:retrying' or
'*0000Z/foo*:retrying'
* retrying tasks in 'BAR' family: '*/BAR:retrying' or 'BAR.*:retrying'
* retrying tasks in 'BAR' or 'BAZ' families: '*/BA[RZ]:retrying' or
'BA[RZ].*:retrying'
The old 'MATCH POINT' syntax will be automatically detected and supported. To
avoid this, use the '--no-multitask-compat' option, or use the new syntax
(with a '/' or a '.') when specifying 2 TASK_GLOB arguments.
Arguments:
REG Suite name
[TASK_GLOB ...] Task match pattern(s)
Options:
-h, --help show this help message and exit
-s STATE, --state=STATE
Reset task state to STATE, can be succeeded, waiting,
submitted, failed, running, submit-failed, expired
-O OUTPUT, --output=OUTPUT
Find task output by message string or trigger string,
set complete or incomplete with !OUTPUT, '*' to set
all complete, '!*' to set all incomplete. Can be used
more than once to reset multiple task outputs.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
-m, --family (Obsolete) This option is now ignored and is retained
for backward compatibility only. TASK_GLOB in the
argument list can be used to match task and family
names regardless of this option.
--no-multitask-compat
Disallow backward compatible multitask interface.

The scheduler will run as a daemon unless you specify --no-detach.
If the suite is not already registered (by "cylc register" or a previous run)
it will be registered on the fly before start up.
% cylc run REG
Run the suite registered with name REG.
% cylc run
Register $PWD/suite.rc as $(basename $PWD) and run it.
(Note REG must be given explicitly if START_POINT is on the command line.)

(specified in the suite.rc or on the command line). Any dependence on tasks
prior to the suite initial cycle point is ignored.
A "warm start" (-w/--warm) starts from a given cycle point later than the suite
initial cycle point (specified in the suite.rc). Any dependence on tasks prior
to the given warm start cycle point is ignored. The suite initial cycle point

Set the initial cycle point. Required if not defined
in suite.rc.
15.6.3.61. scan¶
Usage: cylc [discovery] scan [OPTIONS] [HOSTS ...]
Print information about running suites.
By default, it will obtain a listing of running suites for the current user
from the file system, before connecting to the suites to obtain information.
Use the -o/--suite-owner option to get information of running suites for other
users.
If a list of HOSTS is specified, it will obtain a listing of running suites by
scanning all ports in the relevant range for running suites on the specified
hosts. If the -a/--all option is specified, it will use the global
configuration "[suite servers]scan hosts" setting to determine a list of hosts
to scan.
Suite passphrases are not needed to get identity information (name and owner).
Titles, descriptions, state totals, and cycle point state totals may also be
revealed publicly, depending on global and suite authentication settings. Suite
passphrases still grant full access regardless of what is revealed publicly.
WARNING: a suite suspended with Ctrl-Z will cause port scans to hang until the
connection times out (see --comms-timeout).
Arguments:
[HOSTS ...] Hosts to scan instead of the configured hosts.
Options:
-h, --help show this help message and exit
-a, --all Scan all port ranges in known hosts.
-n PATTERN, --name=PATTERN
List suites with name matching PATTERN (regular
expression). Defaults to any name. Can be used
multiple times.
-o PATTERN, --suite-owner=PATTERN
List suites with owner matching PATTERN (regular
expression). Defaults to current user. Use '.*' to
match all known users. Can be used multiple times.
-d, --describe Print suite metadata if available.
-s, --state-totals Print number of tasks in each state if available
(total, and by cycle point).
-f, --full Print all available information about each suite.
-c, --color, --colour
Print task state summaries using terminal color
control codes.
-b, --no-bold Don't use any bold text in the command output.
--print-ports Print the port range from the global config file.
--comms-timeout=SEC Set a timeout for network connections to each running
suite. The default is 5 seconds.
--old, --old-format Legacy output format ("suite owner host port").
-r, --raw, --raw-format
Parsable format ("suite|owner|host|property|value").
-j, --json, --json-format
JSON format.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
15.6.3.62. scp-transfer¶
Usage: cylc [util] scp-transfer [OPTIONS]
An scp wrapper for transferring a list of files and/or directories
at once. The source and target scp URLs can be local or remote (scp
can transfer files between two remote hosts). Passwordless ssh must
be configured appropriately.
ENVIRONMENT VARIABLE INPUTS:
$SRCE - list of sources (files or directories) as scp URLs.
$DEST - parallel list of targets as scp URLs.
The source and destination lists should be space-separated.
We let scp determine the validity of source and target URLs.
Target directories are created pre-copy if they don't exist.
Options:
-v - verbose: print scp stdout.
--help - print this usage message.
15.6.3.63. search¶
Usage: cylc [prep] search|grep [OPTIONS] SUITE PATTERN [PATTERN2...]
Search for pattern matches in suite definitions and any files in the
suite bin directory. Matches are reported by line number and suite
section. An unquoted list of PATTERNs will be converted to an OR'd
pattern. Note that the order of command line arguments conforms to
normal cylc command usage (suite name first) not that of the grep
command.
Note that this command performs a text search on the suite definition,
it does not search the data structure that results from parsing the
suite definition - so it will not report implicit default settings.
For case insenstive matching use '(?i)PATTERN'.
Arguments:
SUITE Suite name or path
PATTERN Python-style regular expression
[PATTERN2...] Additional search patterns
Options:
-h, --help show this help message and exit
-x Do not search in the suite bin directory

choose WARNING, only warnings and critical messages will be logged.
Arguments:
REG Suite name
LEVEL INFO, WARNING, NORMAL, CRITICAL, ERROR, DEBUG
Options:
-h, --help show this help message and exit
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.

--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
15.6.3.65. show¶
Usage: cylc [info] show [OPTIONS] REG [TASK_NAME or TASK_GLOB ...]
Query a running suite for:
cylc show REG - suite metadata
cylc show REG TASK_NAME - task metadata
cylc show REG TASK_GLOB - prerequisites and outputs of matched task instances
Multiple TASK_GLOBs can be given. They each match task proxy instances in the
current task pool by task or family name pattern, cycle point pattern, and task
state. They do NOT match any task at any point in the abstract suite graph; if
target task instances do not exist in the current pool you must insert them
first with the "cylc insert" command.
* [CYCLE-POINT-GLOB/]TASK-NAME-GLOB[:TASK-STATE]
* [CYCLE-POINT-GLOB/]FAMILY-NAME-GLOB[:TASK-STATE]
* TASK-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
* FAMILY-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
For example, to match:
* all tasks in a cycle: '20200202T0000Z/*' or '*.20200202T0000Z'
* all tasks in the submitted status: ':submitted'
* retrying 'foo*' tasks in 0000Z cycles: 'foo*.*0000Z:retrying' or
'*0000Z/foo*:retrying'
* retrying tasks in 'BAR' family: '*/BAR:retrying' or 'BAR.*:retrying'
* retrying tasks in 'BAR' or 'BAZ' families: '*/BA[RZ]:retrying' or
'BA[RZ].*:retrying'
The old 'MATCH POINT' syntax will be automatically detected and supported. To
avoid this, use the '--no-multitask-compat' option, or use the new syntax
(with a '/' or a '.') when specifying 2 TASK_GLOB arguments.
Arguments:
REG Suite name
[TASK_NAME or TASK_GLOB ...] Task names or match patterns
Options:
-h, --help show this help message and exit
--list-prereqs Print a task's pre-requisites as a list.
--json Print output in JSON format.

--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-m, --family (Obsolete) This option is now ignored and is retained
for backward compatibility only. TASK_GLOB in the
argument list can be used to match task and family
names regardless of this option.
--no-multitask-compat
Disallow backward compatible multitask interface.
15.6.3.66. spawn¶
Usage: cylc [control] spawn [OPTIONS] REG [TASK_GLOB ...]
Force task proxies to spawn successors at their own next cycle point.
cylc spawn REG - force spawn all tasks in a suite
cylc spawn REG TASK_GLOB ... - force spawn one or more tasks in a suite
Tasks normally spawn on reaching the "submitted" status. Spawning them early
allows running successive instances of the same task out of order. See also
the "spawn to max active cycle points" suite configuration.
Multiple TASK_GLOBs can be given. They each match task proxy instances in the
current task pool by task or family name pattern, cycle point pattern, and task
state. They do NOT match any task at any point in the abstract suite graph; if
target task instances do not exist in the current pool you must insert them
first with the "cylc insert" command.
* [CYCLE-POINT-GLOB/]TASK-NAME-GLOB[:TASK-STATE]
* [CYCLE-POINT-GLOB/]FAMILY-NAME-GLOB[:TASK-STATE]
* TASK-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
* FAMILY-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
For example, to match:
* all tasks in a cycle: '20200202T0000Z/*' or '*.20200202T0000Z'
* all tasks in the submitted status: ':submitted'
* retrying 'foo*' tasks in 0000Z cycles: 'foo*.*0000Z:retrying' or

names regardless of this option.
--no-multitask-compat
Disallow backward compatible multitask interface.
15.6.3.67. stop¶
Usage: cylc [control] stop|shutdown [OPTIONS] REG [STOP]
Tell a suite server program to shut down. In order to prevent failures going
unnoticed, suites only shut down automatically at a final cycle point if no
failed tasks are present. There are several shutdown methods:
1. (default) stop after current active tasks finish
2. (--now) stop immediately, orphaning current active tasks
3. (--kill) stop after killing current active tasks
4. (with STOP as a cycle point) stop after cycle point STOP
5. (with STOP as a task ID) stop after task ID STOP has succeeded
6. (--wall-clock=T) stop after time T (an ISO 8601 date-time format e.g.
CCYYMMDDThh:mm, CCYY-MM-DDThh, etc).
Tasks that become ready after the shutdown is ordered will be submitted
immediately if the suite is restarted. Remaining task event handlers and job
poll and kill commands, however, will be executed prior to shutdown, unless
--now is used.
This command exits immediately unless --max-polls is greater than zero, in
which case it polls to wait for suite shutdown.
Arguments:
REG Suite name
[STOP] a/ task POINT (cycle point), or
b/ ISO 8601 date-time (clock time), or
c/ TASK (task ID).
Options:
-h, --help show this help message and exit
-k, --kill Shut down after killing currently active tasks.
-n, --now Shut down without waiting for active tasks to
complete. If this option is specified once, wait for
task event handler, job poll/kill to complete. If this
option is specified more than once, tell the suite to
terminate immediately.
-w STOP, --wall-clock=STOP
Shut down after time STOP (ISO 8601 formatted)
--max-polls=INT Maximum number of polls (default 0).
--interval=SECS Polling interval in seconds (default 60).
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.

--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
15.6.3.68. submit¶
Usage: cylc [task] submit|single [OPTIONS] REG TASK [...]
Submit a single task to run just as it would be submitted by its suite. Task
messaging commands will print to stdout but will not attempt to communicate
with the suite (which does not need to be running).
For tasks present in the suite graph the given cycle point is adjusted up to
the next valid cycle point for the task. For tasks defined under runtime but
not present in the graph, the given cycle point is assumed to be valid.
WARNING: do not 'cylc submit' a task that is running in its suite at the
same time - both instances will attempt to write to the same job logs.
Arguments:
REG Suite name
TASK [...] Family or task ID (NAME.CYCLE_POINT)
Options:
-h, --help show this help message and exit
-d, --dry-run Generate the job script for the task, but don't submit
it.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
-s NAME=VALUE, --set=NAME=VALUE
Set the value of a Jinja2 template variable in the
suite definition. This option can be used multiple
times on the command line. NOTE: these settings
persist across suite restarts, but can be set again on
the "cylc restart" command line if they need to be
overridden.
--set-file=FILE Set the value of Jinja2 template variables in the
suite definition from a file containing NAME=VALUE
pairs (one per line). NOTE: these settings persist
across suite restarts, but can be set again on the
"cylc restart" command line if they need to be
overridden.
--initial-cycle-point=CYCLE_POINT, --initial-point=CYCLE_POINT, --icp=CYCLE_POINT, --ict=CYCLE_POINT
Set the initial cycle point. Required if not defined
in suite.rc.
15.6.3.69. suite-state¶
Usage: cylc suite-state REG [OPTIONS]
Print task states retrieved from a suite database; or (with --task,
--point, and --status) poll until a given task reaches a given state; or (with
--task, --point, and --message) poll until a task receives a given message.
Polling is configurable with --interval and --max-polls; for a one-off
check use --max-polls=1. The suite database does not need to exist at
the time polling commences but allocated polls are consumed waiting for
it (consider max-polls*interval as an overall timeout).
Note for non-cycling tasks --point=1 must be provided.
For your own suites the database location is determined by your
site/user config. For other suites, e.g. those owned by others, or
mirrored suite databases, use --run-dir=DIR to specify the location.
Example usages:
cylc suite-state REG --task=TASK --point=POINT --status=STATUS
returns 0 if TASK.POINT reaches STATUS before the maximum number of
polls, otherwise returns 1.
cylc suite-state REG --task=TASK --point=POINT --status=STATUS --offset=PT6H
adds 6 hours to the value of CYCLE for carrying out the polling operation.
cylc suite-state REG --task=TASK --status=STATUS --task-point
uses CYLC_TASK_CYCLE_POINT environment variable as the value for the CYCLE
to poll. This is useful when you want to use cylc suite-state in a cylc task.
Arguments:
REG Suite name
Options:
-h, --help show this help message and exit
-t TASK, --task=TASK Specify a task to check the state of.
-p CYCLE, --point=CYCLE
Specify the cycle point to check task states for.
-T, --task-point Use the CYLC_TASK_CYCLE_POINT environment variable as
the cycle point to check task states for. Shorthand
for --point=$CYLC_TASK_CYCLE_POINT
--template=TEMPLATE Remote cyclepoint template (IGNORED - this is now
determined automatically).
-d DIR, --run-dir=DIR
The top level cylc run directory if non-standard. The
database should be DIR/REG/log/db. Use to interrogate
suites owned by others, etc.; see note above.
-s OFFSET, --offset=OFFSET
Specify an offset to add to the targeted cycle point
-S STATUS, --status=STATUS
Specify a particular status or triggering condition to
check for. Valid triggering conditions to check for
include: 'fail', 'finish', 'start', 'submit' and
'succeed'. Valid states to check for include:
'runahead', 'waiting', 'held', 'queued', 'expired',
'ready', 'submit-failed', 'submit-retrying',
'submitted', 'retrying', 'running', 'failed' and
'succeeded'.
-O MSG, -m MSG, --output=MSG, --message=MSG
Check custom task output by message string or trigger
string.
--max-polls=INT Maximum number of polls (default 10).
--interval=SECS Polling interval in seconds (default 60).
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
15.6.3.70. test-battery¶
cd "/Users/oliver/cylc-flow"
Usage: cylc test-battery [...]
Run automated Cylc and Parsec tests, under (by default):
/Users/oliver/cylc-flow/tests/.
Options and arguments are appended to "prove -j $NPROC -s -r ${@:-tests}".
NPROC is the number of concurrent processes to run, which defaults to the
global config "process pool size" setting.
The tests ignore normal site/user global config and instead use the file:
/Users/oliver/cylc-flow/etc/global-tests.rc
This should specify test job hosts under the [test battery] section, plus any
other critical settings settings, including [hosts] configuration for test job
hosts (and special batchview commands like qcat if available). Additional
global config items can be added on the fly using the create_test_globalrc
shell function defined in the test_header.
Suite run directories are only cleaned up for passing tests on the suite host.
Set "export CYLC_TEST_DEBUG=true" to print failed-test stderr to the terminal.
To change the test file comparision command from "diff -u" do (for example):
export CYLC_TEST_DIFF_CMD='xxdiff -D'
Some test suites submit jobs to the 'at' so atd must be up on the job hosts.
Commits or Pull Requests to cylc/cylc-flow on GitHub will trigger Travis CI to
run generic (non platform-specific) tests - see /Users/oliver/cylc-flow/.travis.yml.
By default all tests are executed. To run just a subset of them:
* list individual tests or test directories to run on the comand line
* list individual tests or test directories to skip in $CYLC_TEST_SKIP
* skip all generic tests with CYLC_TEST_RUN_GENERIC=false
* skip all platform-specific tests with CYLC_TEST_RUN_PLATFORM=false
List specific tests relative to /Users/oliver/cylc-flow (i.e. starting with "test/").
Some platform-specific tests are automatically skipped, depending on platform.
Platform-specific tests must set "CYLC_TEST_IS_GENERIC=false" before sourcing
the test_header.
Tests requiring the sqlite3 CLI must be skipped if sqlite3 is not installed (it
is not otherwise a Cylc software prerequisite):
| if ! which sqlite3 > /dev/null; then
| # Skip the remaining 3 tests.
| skip 3 "sqlite3 not installed?"
| purge_suite $SUITE_NAME
| exit 0
| fi
Options:
-h, --help Print this help message and exit.
--chunk CHUNK Divide the test battery into chunks and run the specified
chunk. CHUNK takes the format 'a/b' where 'b' is the number
of chunks to divide the battery into and 'a' is the number
of the chunk to run (1 >= a >= b).
Examples:
Run the full test suite with the default options.
cylc test-battery
Run the full test suite with 12 processes
cylc test-battery -j 12
Run only tests under "tests/cyclers/"
cylc test-battery tests/cyclers
Run only "tests/cyclers/16-weekly.t" in verbose mode
cylc test-battery -v tests/cyclers/16-weekly.t
Run only tests under "tests/cyclers/", and skip 00-daily.t
export CYLC_TEST_SKIP=tests/cyclers/00-daily.t
cylc test-battery tests/cyclers
Run the first quarter of the test battery
cylc test-battery --chunk '1/4'
Re-run failed tests
cylc test-battery --state=save
cylc test-battery --state=failed
15.6.3.71. trigger¶
Usage: cylc [control] trigger [OPTIONS] REG [TASK_GLOB ...]
Manually trigger tasks.
cylc trigger REG - trigger all tasks in a running suite
cylc trigger REG TASK_GLOB ... - trigger one or more tasks in a running suite
NOTE waiting tasks that are queue-limited will be queued if triggered, to
submit as normal when released by the queue; queued tasks will submit
immediately if triggered, even if that violates the queue limit (so you may
need to trigger a queue-limited task twice to get it to submit immediately).
For single tasks you can use "--edit" to edit the generated job script before
it submits, to apply one-off changes. A diff between the original and edited
job script will be saved to the task job log directory.
Multiple TASK_GLOBs can be given. They each match task proxy instances in the
current task pool by task or family name pattern, cycle point pattern, and task
state. They do NOT match any task at any point in the abstract suite graph; if
target task instances do not exist in the current pool you must insert them
first with the "cylc insert" command.
* [CYCLE-POINT-GLOB/]TASK-NAME-GLOB[:TASK-STATE]
* [CYCLE-POINT-GLOB/]FAMILY-NAME-GLOB[:TASK-STATE]
* TASK-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
* FAMILY-NAME-GLOB[.CYCLE-POINT-GLOB][:TASK-STATE]
For example, to match:
* all tasks in a cycle: '20200202T0000Z/*' or '*.20200202T0000Z'
* all tasks in the submitted status: ':submitted'
* retrying 'foo*' tasks in 0000Z cycles: 'foo*.*0000Z:retrying' or
'*0000Z/foo*:retrying'
* retrying tasks in 'BAR' family: '*/BAR:retrying' or 'BAR.*:retrying'
* retrying tasks in 'BAR' or 'BAZ' families: '*/BA[RZ]:retrying' or
'BA[RZ].*:retrying'
The old 'MATCH POINT' syntax will be automatically detected and supported. To
avoid this, use the '--no-multitask-compat' option, or use the new syntax
(with a '/' or a '.') when specifying 2 TASK_GLOB arguments.
Arguments:
REG Suite name
[TASK_GLOB ...] Task match pattern(s)
Options:
-h, --help show this help message and exit
-e, --edit Manually edit the job script before running it.
-g, --geditor (with --edit) force use of the configured GUI editor.
--user=USER Other user account name. This results in command
reinvocation on the remote account.
--host=HOST Other host name. This results in command reinvocation
on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--port=INT Suite port number on the suite host. NOTE: this is
retrieved automatically if non-interactive ssh is
configured to the suite host.
--use-ssh Use ssh to re-invoke the command on the suite host.
--ssh-cylc=SSH_CYLC Location of cylc executable on remote ssh commands.
--no-login Do not use a login shell to run remote ssh commands.
The default is to use a login shell.
--comms-timeout=SEC, --pyro-timeout=SEC
Set a timeout for network connections to the running
suite. The default is no timeout. For task messaging
connections see site/user config file documentation.
--print-uuid Print the client UUID to stderr. This can be matched
to information logged by the receiving suite server
program.
--set-uuid=UUID Set the client UUID manually (e.g. from prior use of
--print-uuid). This can be used to log multiple
commands under the same UUID (but note that only the
first [info] command from the same client ID will be
logged unless the suite is running in debug mode).
-f, --force Do not ask for confirmation before acting. Note that
it is not necessary to use this option if interactive
command prompts have been disabled in the site/user
config files.
-m, --family (Obsolete) This option is now ignored and is retained
for backward compatibility only. TASK_GLOB in the
argument list can be used to match task and family
names regardless of this option.
--no-multitask-compat
Disallow backward compatible multitask interface.
15.6.3.72. upgrade-run-dir¶
Usage: cylc [admin] upgrade-run-dir SUITE
For one-off conversion of a suite run directory to cylc-6 format.
Arguments:

'cylc view -i,--inline SUITE' for comparison.
Arguments:
SUITE Suite name or path
Options:
-h, --help show this help message and exit
--strict Fail any use of unsafe or experimental features.
Currently this just means naked dummy tasks (tasks
with no corresponding runtime section) as these may
result from unintentional typographic errors in task
names.
-o FILENAME, --output=FILENAME
Specify a file name to dump the processed suite.rc.
--profile Output profiling (performance) information
-u RUN_MODE, --run-mode=RUN_MODE
Validate for run mode.

on the remote account.
-v, --verbose Verbose output mode.
--debug Output developer information and show exception
tracebacks.
--suite-owner=OWNER Specify suite owner
-s NAME=VALUE, --set=NAME=VALUE
Set the value of a Jinja2 template variable in the

the "cylc restart" command line if they need to be
overridden.
--set-file=FILE Set the value of Jinja2 template variables in the
suite definition from a file containing NAME=VALUE
pairs (one per line). NOTE: these settings persist
across suite restarts, but can be set again on the
"cylc restart" command line if they need to be
overridden.

Usage: cylc [prep] view [OPTIONS] SUITE
View a read-only temporary copy of suite NAME's suite.rc file, in your
editor, after optional include-file inlining and Jinja2 preprocessing.
The edit process is spawned in the foreground as follows:
% <editor> suite.rc
Where <editor> can be set in cylc global config.
For remote host or owner, the suite will be printed to stdout unless
the '-g,--gui' flag is used to spawn a remote GUI edit session.
See also 'cylc [prep] edit'.
Arguments:
SUITE Suite name or path
Options:
-h, --help show this help message and exit
-i, --inline Inline include-files.
-e, --empy View after EmPy template processing (implies
'-i/--inline' as well).
-j, --jinja2 View after Jinja2 template processing (implies
'-i/--inline' as well).
-p, --process View after all processing (EmPy, Jinja2, inlining,
line-continuation joining).
-m, --mark (With '-i') Mark inclusions in the left margin.
-l, --label (With '-i') Label file inclusions with the file name.
Line numbers will not correspond to those reported by
the parser.

tracebacks.
--suite-owner=OWNER Specify suite owner
-s NAME=VALUE, --set=NAME=VALUE
Set the value of a Jinja2 template variable in the
suite definition. This option can be used multiple
times on the command line. NOTE: these settings
persist across suite restarts, but can be set again on
the "cylc restart" command line if they need to be
overridden.
--set-file=FILE Set the value of Jinja2 template variables in the
suite definition from a file containing NAME=VALUE
pairs (one per line). NOTE: these settings persist
across suite restarts, but can be set again on the
