Make this script executable and make it the login shell (7th field of the line
in /etc/passwd); when it exits, the user will log out:
========================= begin =======================
#! /bin/sh
# Sample menu script
#
while true
do
echo -n "
Here are your choices -
1. Change your password
2. See today's date
3. Log off
Which do you want? "
x=
while [ -z "$x" ]
do
read x
done
echo
case $x in
1)
passwd
;;
2)
date
;;
3)
exit 0
;;
*)
echo -e "$x is a bad choice!\a"
;;
esac
done
========================== end ========================
