GNU grep has `--include', so I often use something like the
$ grep -rF --include='*.[ch]' G_foo lib/ raster/
$ grep -rF --include=\*.html g.bar ./
Unfortunately, there's no way to skip directories matching a
wildcard (e. g.: --exclude=.svn), at least as of GNU grep 2.5.1.
The `-l' option could be useful as well, e. g.:
$ less $(grep -rlF --include='*.[ch]' G_foo raster/)
