Use Perl like grep

Much better alternatives - grep-alikes using perl regexps. With more options, and nicer outputs.

Alternatives

There are 4 alternatives - vote for the best!

If you've ever tried "grep -P" you know how terrible it is. Even the man page describes it as "highly experimental". This function will let you 'grep' pipes and files using Perl syntax for regular expressions.

The first argument is the pattern, e.g. '/foo/'. The second argument is a filename (optional).

Know a better way?
