Heres a case statement I wrote to check current users logged in,
what they are doing etc …
[root@localhost Bash]# cat case.sh
#!/bin/bash
echo “1 – Shows a listing of currently logged-in users “
echo “2 – Shows who is logged on and what they are doing “
echo “3 – Shows a list of last logged-in users, including login time,
logout time, login IP address, etc”
echo ” 4 – Same as last, except that by default it shows a log of the
file /var/log/btmp, which contains all the bad login attempts.”
echo ” 5 – This reports data maintained in /var/log/lastlog,
which is a record of the last time a user logged in.”
echo “6 – Exit Menu”
echo “Enter your Options “
read e;
case $e in
1) who ;;
2) w ;;
3) last ;;
4) lastb ;;
5) lastlog ;;
6) exit;;
*) echo “$e Opps Option not available, Please choose between 1 to 5″
esac
Save the file and exit
