These are really cool.

But one thing I haven't seen mentioned in all these grep tricks is
grep -r.

The output of grep --help on my (Fedora) box with grep-2.5.1 includes

Output control:
  -d, --directories=ACTION  how to handle directories
                            ACTION is 'read', 'recurse', or 'skip'
  -D, --devices=ACTION      how to handle devices, FIFOs and sockets
                            ACTION is 'read' or 'skip'
  -R, -r, --recursive       equivalent to --directories=recurse

..so I just do "grep -r thing-to-find".

Incidentally, -H will print the filename for each match.
