Another option instead of 'find' in BASH is the globstar option. If set then pathname expansion will include zero or more subdirectories:

  ls **/*.c

Results in something like:

  array.c                   helpers/gendec.c         msg.c
  awkgram.c                 helpers/mb_cur_max.c     node.c
  awklib/eg/lib/grcat.c     helpers/scanfmt.c        old-extension/bindarr.c

Turn on with:

  shopt -s globstar
