in reply to grep -P

If you don't need the more complex command-line options of grep, you can just use perl -ne 'print if (/pat/)'. Even the trickier options usually come down to just a small variation on that theme.

    I guess -R (recurse directory) and -l (print filenames containing matches) are two that I use often. The one liner is a bit of a mouthful.

    But just for fun:

    perl -MFile::Find -ne 'find(& sub { $f = 1; if (/pat/ and $f) { $f = 0 +; print $File::Find::name . "\n" }, "mydir");'

    ...or something like that.
