I am comparing multiple strings in bash. Currently I have a script that looks like this:
if [ "$f" != "A-C" ] && [ "$f" != "D-F" ] && [ "$f" != "G-I" ] && [ "$f" != "J-L" ] && [ "$f" != "M-O" ] && [ "$f" != "P-R" ] && [ "$f" != "S-U" ] && [ "$f" != "V-X" ] && [ "$f" != "Y&Z" ] && [ "$f" != "#" ]; then #if f is a directory
How can I shorten this?

Ended up with something like this:
[[ "$f" != +(A-C|D-F|G-I|J-L|M-O|P-R|S-U|V-X|Y&Z|#) ]]

I don't think you need the quotes on the right hand side (there's nothing special inA-Cto quote, it's not a character class without the brackets).@(foo|bar)to match exactly once, with+it'll match e.g.A-CJ-L
