Huh... that's interesting. I wouldn't have expected it, but it turns out you don't "lose" the value of errexit in a process substitution the way you do in a command substitution. imadev:~$ bash -c 'set -e; x=$(set +o); grep errexit <<<"$x"' set +o errexit imadev:~$ bash -c 'set -e; grep errexit <(set +o)' set -o errexit So, assuming Nikolai still wants to go with his current design, I guess he could use code like this: read -rd '' settings < <(set +o) ... eval "$settings"
