My interpretation is that he wants to write a "portable function" for someone else to use, and that he wants to use errexit while inside it, and therefore he believes he needs to retrieve the current value of errexit so that the can restore that value right before exiting. So, he's trying to capture stuff=$(set +o) to retrieve the settings, but since errexit gets disabled in (some? I don't know/care) subshells, it's not acting as he expects. imadev:~$ bash -c 'set -e; set +o | grep errexit' set -o errexit imadev:~$ bash -c 'set -e; x=$(set +o); echo "$x" | grep errexit' set +o errexit I reiterate my position that set -e (errexit) should be avoided. It brings nothing but suffering.
