Subject: How to print the trapped command for a specific signal
To: zsh-users <zsh-users@zsh.org>
Content-Type: text/plain; charset="UTF-8"

Hi,

I only see the way to print the trapped commands for all signals. Is
there a way to print the trapped command for a specific signal?
Thanks.

$ cat main.sh
#!/usr/bin/env zsh
# vim: set noexpandtab tabstop=2:

set -v
trap "echo 'Hello World!'" EXIT
trap "echo 'Hello World1!'" ZERR
trap
$ ./main.sh
trap "echo 'Hello World!'" EXIT
trap "echo 'Hello World1!'" ZERR
trap
trap -- 'echo '\''Hello World!'\' EXIT
trap -- 'echo '\''Hello World1!'\' ZERR
Hello World!

Peng
