You're close. You just need to tell Perl what parts of the line you want to capture - how else would Perl know that you're not just interested in FILE_INPUT but also stuff following it? See perlre on how to capture things into $1. Basically the following RE should give you a start:

/(FILE_INPUT\w+)/

If the match is successful (and only then), the captured value will be stored in $1.
