+== rmdir ==
+Removes directories. The '''rmdir''' is a safer approach than using '''rm -r''' as it will only act on empty directories.

-To copy a directory and all of its contents:
-{{{
-[tulaneID@cypress1 ~]$ cp -r dir1 dir2

+In the example below sourcefile already exists, and destinationfile may or may not exist and will become a copy of sourcefile.
+{{{
+[tulaneID@cypress1 ~]$ cp sourcefile destinationfile
+}}}
+To copy a directory and all of its contents we use the recursive flag '''-r''':
+{{{
+[tulaneID@cypress1 ~]$ cp -r sourcedir destinationdir
+}}}
+
+Take note of the order here: source first, destination second. This is the standard order across most *nix commands.
 === mv ===
 Move a file to a new location.
