Cylc Broadcast

The cylc broadcast command overrides task [runtime] settings in a running scheduler. You can think of it as communicating new configuration settings (including information via environment variables) to selected upcoming tasks via the scheduler.

See cylc broadcast --help for detailed information.

Broadcast settings targeting a specific cycle point expire as the workflow moves on. Otherwise they persist for lifetime of the run, and across restarts, unless cleared with another invocation of the command.
