| Hi,
|  Ganesh asked how a normal user could halt the system.
|  Well, if you are using the computer from the console (no telnet,rsh
| etc.), you could just type Ctrl-Alt-Del like in DOS and the system
| will go through a complete shutdown (look at your /etc/inittab).
|     Rebooting the computer needs root access. In the above case, the
| "init" program running as root did it for you. You could also do it
| by making a separate login , say "shutdown" with login shell changed
| to something like "/sbin/shutdown -r now" instead of the usual
| "/bin/bash" or "/bin/sh". This user should obviously have root perms.
| (UID=0). Due to the security risk involved, this might be a safer
| solution than changing .bash_profile as Ashok suggested.
