Hi all,
I usually use the following construct, to protect against any kind of value
for FOO, be it empty or starting with a special character:
test X"${FOO+set}" = X"set" || FOO=$foo
I know here FOO is never expanded if it's not unset, so cannot be expanded
as '-', but I also use the same construct as:
test X"${FOO}" = X"something" || FOO=$foo
and I'm so used at typing the X"..." that I type them quite automatically...
also some of the quotes may not be needed (if something is not some thing :)
:) :) ), but it seems more readable that way :-)
Regards,
Bernard
