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 ' .
