what shell are you using? You can tell by entering this command:
Code:
echo $SHELL

your bash options have
Code:
nounset         on
somewheree the shell has
set -u
or
set -o nounset
being called on it
i think
set +o nounset
should fix it as well if you can't find where it's being set
(in true unix fasion + takes the option away where - adds it -- go figure)
look at bash options with
set -o
