how to fork process from shell action

[j-lakeman]

This is what I've tried so far:

- shell: pgrep -f $(which cryptomator) || cryptomator & disown # check if Cryptomator is running and start it if needed

This would start Cryptomator as expected but gets stuck possibly waiting for the process to end. How can I fork it so that it becomes independent of the organize process?

Current shell is synchronous.

organize/actions/shell.py uses subprocess.run(..., stdout=PIPE, stderr=STDOUT, shell=True), so the action waits for the shell command to finish, and a background child that inherits those pipes can still keep the call open.

So there isn't a built-in detach mode today. The practical workaround is to launch something that fully detaches on your platform, for example a wrapper script that returns immediately, or a command such as nohup cryptomator >/dev/null 2>&1 </dev/null &.

Thanks a lot, this finally works!
What does the third redirection </dev/null do though? Is it for standard input?
