Question: How do I get a recursive directory listing?

Answer: One of the following may do what you want:

ls -R (not all versions of "ls" have -R)
find . -print (should work everywhere)
du -a . (shows you both the name and size)

If you're looking for a wildcard pattern that will match all ".c" files in this directory and below, you won't find one, but you can use % some-command `find . -name '*.c' -print` "find" is a powerful program. Learn about it.
