Full Discussion: Who is the current user

Sign on to your system and type the command "env". I believe that you will find both variables set. At least I see them both on redhat.

And type "man environ". I see them as the first two ducumented environment settings. What do you see?

Maybe your login scripts unset both environment variables?

But looking at this thread and your other thread involving mtime, the more probable answer is that you are having some difficulties with programs that you write.
