Guess what I'm asking for would be more along the lines of this, at least in bash 5.3: if [[ -v COLUMNS || -v LINES ]]; then shopt -u checkwinsize else ( : ) trap '( : )' SIGWINCH fi Note that any script where COLUMNS or LINES in the environment is relevant would have to have the first half of that right now. With a modern env, I can even do: #!/usr/bin/env --split-string=bash -i set +o histexpand +o history +o monitor shopt -u expand_aliases And also get what I want, though there may be some downside I'm unaware of. Even living in RHEL 7, I could just use a script or alias to call the given script with those options set, come to think of it. My work machine is six bash major versions back. I'd still rather things improve at some point.
