: test X"${FOO+set}" = X"set" || FOO=$foo
I can appreciate having fixed conventions for things like this, and I
usually do quote on both sides of the =.
Anyways, what would be really cool is to find a LHS expansion that would
either expand to "set" or to "unset" depending on whether the variable was
set or not. I haven't been able to think of one, though. Does anyone
know it that could be done?
This trick is kind of cool, but it's the inverse of what I originally
looked for:
if test ${VAR+un}set != unset; then
# VAR is set
fi
and
if test ${VAR+un}set != set; then
# VAR is unset
fi
