While we're on something that is essentially a more powerful "find and grep", I wrote this years ago:

Like ack, it uses perl's regexes... just add more file extensions and you're golden. The nice thing is you do:

  cg pattern

which gives you a list with what it found, which file, the line number and an index... then you

  vg index

and it opens that file at that line.
