Well, go to the top of a directory tree and type:

   find . -print

and compare this with 

   ls -R . | cat     

(or "ls -1R" -- ls outputs differently if it believes that it isn't
connected to a tty)


The output is different.  One happens to be easier to work with, IMHO.

"find" happens to be one of my favorite tools.
