starnge behavior of shutdown
Hi All,
I am having a stange behavior of my system. I used to use the following command to reboot my system
Shutdwon -r 0
It sometimes reboot my system and some time it is just halt the system.
If I do the hard reboot there is no probem absolutely.
I tried intit 6 this also behave in the same way.
Also I want to know why reboot is having a softlink to halt reboot -> halt
So reboot should do the same thing as halt?
Thanks & Regards
Gauri

I put this here because it is a 'behavior' type question..
I seem to remember doing ls .* and getting all the .-files, like
.profile
.login
etc.
But ls .* doesn't do that, it lsts the contents of every .*-type subdirectory.
Is it supposed to?

LEARN ABOUT ULTRIX
reboot
reboot(8) System Manager's Manual reboot(8)
Name
reboot - automatic reboot procedures
Syntax
/etc/reboot [ -n ] [ -q ]
Description
The ULTRIX system is booted by loading a kernel image, usually into memory at location zero and transferring to zero. Because the system
is not reenterable, the kernel image must be read in from disk each time the system is bootstrapped.
When the reboot of a running system is desired, is normally used. If there are no users, can be used. The command causes the disks to be
synced, and then a multiuser reboot is initiated. The system is booted and an automatic disk check is performed. If the procedure suc-
ceeds, the system is then brought up for the users.
The system will reboot itself after a power failure or after a crash, provided auto-restart is enabled on your system. A consistency check
of the file systems will be performed and, unless the check fails, the system will resume multiuser operations.
Options
-n Prevents the disks from being synced.
-q Reboots quickly and ungracefully, without shutting down running processes first.
