You should have told, if you use the Borne shell, the cshell or the
Korn shell. I don't know about the Korn shell and am not sure about
your version of the Bourne shell, but the cshell (at least on vanilla
4.2BSD) hashes all commands it finds on invocation. So if you create
a new script or new program, you have to say "rehash" to force cshell
to rescan all directories in your path, before the shell recognizes
the command from everywhere.

Hope this helpes
