Doug,
2 suggestions:
- 1 - go to www.computerhope.com -- very good, and seemingly complete, 
documentation for OSX, Linux, DOS, Windows.  You can get the exact 
syntax for the command(s) you want.

- 2 - get whatever you end up with working from the command line -- 
FIRST --, then screw around with getting LEP to work.  I have found 
some commands just will Not run through LEP (xCopy is one).
