I have never used SHELLOPTS, and have never tested this, but: Does "unset SHELLOPTS" not work?
No. It's managed by the shell and readonly. You can remove the export attribute, though.
It would probably be useful to have that as one of the initial commands
in every script, perhaps after saving its previous value if that is
needed, and then if it is wanted for a sub-shell or exec'd script
set it again, as in:
SHELLOPTS=whatever script
You can't do this; you have to change the options using `set -o'.
SHELLOPTS reflects the current state of the options controllable by
`set -o'.
