Perform perl regexp (because grep on OS X (still) doesn't support it):

perl -ne 'print if /[regexp]/'

Print can use capturing groups or named capturing groups:

perl -ne 'print "$1\n" if /(.*)/'

Find and open with arbitrary command:

find [path] [arguments / filters] -print0 | xargs -0 [command] [&]

Useful terminal commands (OS X):
