Bash Version: 5.2
Patch Level: 21
Release Status: release
Description:
The man-page says under set -e: "...A trap on ERR, if set, is executed
before the shell exits. ..."
If such a handler sets "set +e", the original flow is resumed after the
handler exits.
I would expect that once the exit due to "set -e" is initiated, it
should not be cancelable.
The example script in Repeat-By produces the following output:
main: the next command will fail
handler: the next command will fail
handler: after failing command
main: after failing command
Expected output:
main: the next command will fail
handler: the next command will fail
handler: after failing command
Repeat-By:
----------------- snip -----------------
handler () {
set +e
echo "handler: the next command will fail"
false
echo "handler: after failing command"
}
trap handler ERR
set -e
echo "main: the next command will fail"
false
echo "main: after failing command"
