kill-child-jobs

Examples of how to kill all child jobs when a shell script exits.

all-full-example.sh starts some jobs, disowns one of them, and kills all jobs when it exits. pkill-P-full-example.sh does the same except it kills all child processes when it exits.

The remaining scripts in the root are variants of the kill_child_jobs() function. The test/test-all.sh script tests them all and generates the following output showing which version of the kill_child_jobs() function works in each shell:

Legend:
    ∞=script does not halt (after 1 second timeout)
    X=disown unsupported by shell
    ☠=all children killed
    🏃=all children still running
    ✔️=expected result (job killed, disowned child alive)
