Unix Tip #4326- January 14, 2025
TRACKING OF LOGINS AND LOGOUTS
In the .login file add the commands:
------------------------------------
echo login time `date` >> .daylogs/masterlog
grep -i "sun" .daylogs/masterlog > .daylogs/sunday.log
grep -i "mon" .daylogs/masterlog > .daylogs/monday.log
grep -i "tue" .daylogs/masterlog > .daylogs/tuesday.log
grep -i "wen" .daylogs/masterlog > .daylogs/wensday.log
grep -i "thu" .daylogs/masterlog > .daylogs/thursday.log
grep -i "fri" .daylogs/masterlog > .daylogs/friday.log
grep -i "sat" .daylogs/masterlog > .daylogs/saturday.log
In the .logout file add this line
-----------------------------------
echo logout time `date`>> .daylogs/masterlog
This script assumes you have a hidden
directory called .daylogs this helps keep it
out of sight and away from prying eyes and
if you keep root ownership of the directory
change the mode to:
chmod 744 .daylogs
This will not allow anyone to get in to the
directory to look around.
NOTE: All tips provided are USE AT YOUR OWN RISK. Tips are submitted
by various unix admins around the globe. UGU suggest you read and
test each tip in a non-volitile environment before placing into
production.
