a backslash works perfect on confeds. If you use ..... \(1\) .... it'll treat
the bracket as a character to match instead of a special character, so it'll ca
tch the (1) in the path. Check out the link below on what a backslash does.

You also have to watch confeds. Recently ran across one where _1_ would
not match on (1).
