Transform exit handlers of the form trap cleanup EXIT [INT] [TERM] [QUIT] [HUP] [ERR] (where cleanup is idempotent) to trap cleanup EXIT This fixes a common bash antipattern. Each of the above signals causes the script to exit. For each signal, bash first handles the signal by running `cleanup` and then runs `cleanup` again when handling EXIT. (Exception: `vscode/*` prevents the second run of `cleanup` by removing the trap in cleanup`). Simplify the cleanup logic by just trapping exit, which is always run when the script exits due to any of the above signals. Note: In case of borgbackup, the exit handler is not idempotent, but just trapping EXIT guarantees that it's only run once. |
