Determine if `set -e` flag if is active in bash

Question

In a bash script/shell, is there a programmatic way to determine if the set -e flag is active?

I just need a boolean letting me know if it\'s on/off.

Answer 1

$ set -e
$ if grep -q 'errexit' <<<"$SHELLOPTS";then echo "set -e is enabled";else echo "set -e is disabled";fi
set -e is enabled
$ set +e
$ if grep -q 'errexit' <<<"$SHELLOPTS";then echo "set -e is enabled";else echo "set -e is disabled";fi
set -e is disabled
