How can I stop gnu parallel jobs when any one of them terminates?

Question

Suppose I am running N jobs with the following gnu parallel command:

seq $N | parallel -j 0 --progress ./job.sh

How can I invoke parallel to kill all running jobs and accept no more as soon as any one of them exits?

You can use --halt:

seq $N | parallel -j 0 --halt now,done=1 ./job.sh

In newer versions of GNU Parallel you can use '--halt now,success=1' It will exit when a job succeeds and kill running jobs. – Ole Tange Oct 14 '15 at 11:56
Modern syntax for `--halt 2` is `--halt now,fail=1` – Grief Jul 02 '23 at 08:55

You may also use killall perl. It's not accurate way, but easy to remember
