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?

Answer 1

You can use --halt:

seq $N | parallel -j 0 --halt 2 './job.sh; exit 1'

A small problem with that solution is that you cannot tell if job.sh failed.
