When I ssh to a dialup machine, my PATH begins (incorrectly) with
a colon. When I login to a campus workstation, PATH is correct
(without a leading colon).
I use Bash as my login shell. The dialup is running Athena 9.1.22.
I believe the problem may be this fragment at line 138 of
/usr/athena/lib/init/bashrc (version 1.25):
# Standard Athena path
PATH=`/usr/athena/bin/athdir $HOME`:$athena_path:.
unset athena_path
If athdir returns nothing for $HOME, the resulting expansion
incorrectly prepends a colon. Better would be this:
# Standard Athena path
athena_home_bin=$(/usr/athena/bin/athdir "$HOME")
PATH=${athena_home_bin:+$athena_home_bin:}$athena_path:.
unset athena_path athena_home_bin
