[Help-bash] access exit code from within exit trap handler?

[Patrick Schleizer]

Hi!

Code talks. I'll include my question within the following pseudo code.

#!/bin/bash
set -x
exit_handler() {
   ## Is there a way figure out what exit code caused execution of this
handler?
   true "exit code: "
   ## ...
}
trap exit_handler EXIT
true "something..."
if [ "something" = "something" ]; then
   exit 1
fi
## ...
exit 0

Sure, a simple function
exit_() {
   exit_code="$1"
   exit "$exit_code"
}
would probably do, but perhaps this can be avoided?

Cheers,
Patrick
