Thanks for the clarification.
Speaking of 'printenv' - i noticed that
even though $HOSTNAME is set on all of my machines:
aim-nano_03 ~ # echo $HOSTNAME
it does not appear in printenv's output:
aim-nano_03 opt # printenv | grep HOST
aim-nano_03 opt #
Is there something special about $HOSTNAME and how or when it is set?
