There is also rgrep, the recursive grep'er. It can do basic filename
pattern matching. An example from the man page.
Look in all files with a 'c' extension in current direc-
tory and all its subdirectories looking for matches of
'int ' at the beginning of a line, printing the line con-
taining the match with its line number: (two methods)
rgrep -n -R '*.c' '^int ' .
rgrep -n -x c '^int ' .
