} Then Zsh does actually ignore the kill (TERM) signal.
It doesn't ignore the signal, but it may not run the trap either. You
need the trap on EXIT in there:
trap "echo trapped; exit" EXIT INT HUP TERM
That's because it matters whether the shell itself gets the signal, or
an external job that's been run *by* the shell gets the signal.
E.g. if I run a script that executes "sleep" and kill the sleep, the
TERM trap is not run but the EXIT trap will be. If I kill the shell
itself, the TERM trap is run but the EXIT trap is not.
