source: trunk/debathena/debathena/dotfiles/bashrc @ 24793

Revision 24793, 4.2 KB checked in by geofft, 12 years ago (diff)
In dotfiles: * Change from attaching $USER unconditionally to attaching $ATHENA_USER if $DEBATHENA_HOME_TYPE is set to "afs", to avoid an error message if you run the Athena .bashrc in a local account, as e.g. "sudo bash"/"sudo -s" does. Based on a patch from (and Signed-off-by) Thomas Coles <tcoles@mit.edu>.
