xyyz, don't feel too bad. The sort command still give me fits too. I typically need to fiddle with my sort option until I get what I want.
#1freebsddude, that was an awesome link on the sort command! But is only showing the original syntax. Posix has defined a new syntax using the -k option. It's probably time to switch to the newer syntax. Still once you get the old syntax, switching to the newer syntax is easy, so that link is still very good.
That link didn't answer -n question though. If you are specifying the fields, you would probably just add the n to field spec. -n mostly makes sense when use it alone. Here is a command that I need to type several times a week...
du -sk * | sort -n
