#
# clear-queues script, for the CIS labs (or elsewhere?)
#
# should clear any queues that have the following properties:
# - 
# - There is nobody logged in on the computer - when this happens,
# clear the entire queue doing a `lprm -a all`
# - The print job had some sort of ERROR
# - The print job is stalled
# - The print job is done, but just sitting there in the queue like
# it owned the place.
# 
#
# this script runs from a crontab like so:
# 0,10,20,30,40,50 * * * * /root/lab-command /usr/local/clear-queues
#
# where lab-command is an ssh script that takes one command-line argument,
# in this case 'clear-queues' the script (this one)
