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.
