root user and any GUI

[Dazed_75]

Joseph,
Yes, I am sure that is true.  Something in trying what JT posted made me
think that as well and when I rechecked the man page for su I was reminded
of the difference although I never really understood the details.  It's
these little discoveries that make life interesting and make me want to
explore.  Basicly, I always thought you were logging in as the other user
but somehow logging in differently,  I guess using su without the "-" is
more like a "steal the identity of".  LOL

JT,

Thanks very much.  I did always know there were environmental differences
but I never knew how to see the difference.  Comparing results of 'env' and
of 'set' before and after the switch was a frustrating experience for
several reasons.  And I never knew about using export without arguments.  I
had only ever seen it used to actually export things.  Probably sounds dumb
to most of you but a revelation to me as it also explains some other things
for me.
