I'm running a GNU Parallel command on a screen session. Unfortunately, I did not put an "&" at the end of the command to push it to the background. Hence I do not have access to the command line on my screen session.

I would like to TERMINATE parallel so that it stops creating new jobs but finishes currently running ones. I will need to do so outside the screen, but I don't think screen -X will work because the screen's command line isn't accepting new commands.

Thanks!

First: The standard way to fix a missing & is:

CTRL-Z

That being said, you probably want to send GNU Parallel a SIGTERM. If you only run one instance, then this should do it:

killall -TERM parallel

  • Thanks! I found that Perl seemed to be responsible for parallel., so I ran killall -TERM perl and got a message saying "no new jobs will be started, but waiting for 5 to finish." That sounds like the desired result.

    Also, thanks for the info on CTRL-Z! I thought Control-Z was basically the same as Control-C and didn't know "stopped" really meant "paused."
