perlfaq3: Is there an IDE or Windows Perl Editor? Has a a pretty good list that, while not Linux specific, many of the entries are available to you.
There's never a shortage of vim or emacs users, support or documentation so either of those are always a safe bet. It would help if we knew more about what you were looking for in an editor. So much is about personal preference and habit that you just have to pick a few and see how they feel.
