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

|
|
|
|
|
|
[`all-full-example.sh`](all-full-example.sh) starts some jobs, disowns |
|
|
|
|
one of them, and kills all jobs when it exits. |
|
|
|
|
[`pkill-P-full-example.sh`](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`](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: |
