I've just tried this on RH Linux and Solaris both with bash (but different bash
version). Some logins I have on those machines are as root and some as a regular
user. Some of the logins yielded the expected output from "echo $REMOTEHOST" but
some didn't produce any output. Can't find the reason for that (and I dont have
time to delve into it now...).
Besides, AFAIK, enviroment variables are all shell dependant as they are created
by the shell. Some might be completely standard, like TERM, but they are all to
the mercy of the shell. (Ofcourse, I would love to be corrected or better
rephrased :-) .
Boaz.
