There traditionally has been no character to generate help. The h
option has traditionally been unused, so would wind up generating
help, much like the ? option generates help. The generation of help
wasn't built into many (any) of the original BSD utilities.
-: is also a good option to try, as is -{}. It is a crap shoot
really. If you don't know how to use the command, you should check
the man page... Typing things at random and expecting them to work is
likely going to cause problems one day...
