# SMaRT (Simple Monitoring and Reporting Tool) - v1.0 for Slackware / Redhat
# Written by ozlo [ozlo@plink.freeservers.com] on 07.22.2002
#
#  SMaRT is a tool that monitors which users are logged into the system, their
#  IP or hostname, terminal, login time, idle time, and will list up to 3 or 4
#  processes they are running. It will refresh every 60 seconds by default, or
#  can be changed to update as often as necessary by changing the lines:
#  [time=`expr $time + 60`] AND [sleep 60] to the desired value. To exit the
#  script once it is running, simply hit CTRL-C.
#
# *NOTE*  
#  If a user is logged in more than one time, the process list might not be
#  displayed correctly. Also, this script works best on smaller systems where
#  there are about 15 or fewer users logged in concurrently. And I decided to
#  not have root's processes displayed since there are usually so many and it
#  would be pointless to monitor that.
