Re: [TCLUG:1769] environment variables

[Jeffrey R Haskovec <hask0025@tc.umn.edu>]

if you are under bash use:

ENVVAR=whatever ; export ENVVAR

csh use:

setenv ENVVAR whatever

echo $PATH

to display it or just type set under bash that lists all environment
variables.

if you want to set some env-variables whenever you log in put them in your
.bash_profile or your .login
