Subject: | bash: please provide an easy way to spawn a new process group from script |
Date: | Sun, 1 Nov 2020 01:54:29 +0100 |
I was battling this problem now for several hours i wanted to do this: { a | b; } & pid=$! and then later kill -- -$pid to kill all the processes spawned by the pipeline. But this proved to be immensely complicated as no new process group is spawned from within a script (unless set -m which is not recommended as it blocks signals) Please, provide a syntactic construct to spawn a new process group (or at least there should be some usable command to do that). Thank you clime
