Scripting

Look into the bash command 'init', these are run levels for the kernel. Init 0 will shutdown a linux box from CLI, init 6 is what you're looking for I think.

I tend to use the shutdown (with -r for your reboot) command for the timing options, i.e

shutdown -r now
shutdown -r 08:00 // at 8am
shutdown -r +5 // in 5 minutes
shutdown -r now "message"

Great for Windows machines, Pieter,but not a great deal of use for Linux boxes :-)

Also, you know it's my job to misread posts.

this site, and the fact that I've actually used this command on linux numerous times, beg to differ [8D]
Despite my job as Windows packager, I actually often run linux on at least one machine as main OS at home.

Re-reading the original post, I am assuming you can run the linux command directly from kbox? And you don't have to take a detour via some windows-compliant command?

Thanks for the feedback on this. Originally I was looking at using halt, but was not clear regarding the KBOX environment variables for locations or if it's better to include a script file in the execution of the scripting task rather then using the command and parameter fields.

BTW, it's good to see some Linux feedback. When I began deploying our XenServers I was concerned that we wouldn't be able to support them with the KBOX since it's not officially supported. However, after a little trial and error getting the client loaded, it's been a great management tool for both VM hosts and guests.

Thanks again.

Info on the shutdown command (for XenServer:Linux)

SHUTDOWN(8) Linux System Administratorâs Manual SHUTDOWN(8)

NAME
shutdown - bring the system down

SYNOPSIS
/sbin/shutdown [-t sec] [-arkhncfFHP] time [warning-message]

DESCRIPTION
shutdown brings the system down in a secure way. All logged-in users are notified
that the system is going down, and login(1) is blocked. It is possible to shut the
system down immediately or after a specified delay. All processes are first noti-
fied that the system is going down by the signal SIGTERM. This gives programs like
vi(1) the time to save the file being edited, mail and news processing programs a
chance to exit cleanly, etc. shutdown does its job by signalling the init process,
asking it to change the runlevel. Runlevel 0 is used to halt the system, runlevel
6 is used to reboot the system, and runlevel 1 is used to put to system into a
state where administrative tasks can be performed; this is the default if neither
the -h or -r flag is given to shutdown. To see which actions are taken on halt or
reboot see the appropriate entries for these runlevels in the file /etc/inittab.

OPTIONS
-a Use /etc/shutdown.allow.

-t sec Tell init(8) to wait sec seconds between sending processes the warning and
the kill signal, before changing to another runlevel.

-k Donât really shutdown; only send the warning messages to everybody.

-r Reboot after shutdown.

-h Halt or poweroff after shutdown.

-H Halt action is to halt or drop into boot monitor on systems that support it.

-P Halt action is to turn off the power.

-n [DEPRECATED] Donât call init(8) to do the shutdown but do it ourself. The
use of this option is discouraged, and its results are not always what youâd
expect.

-f Skip fsck on reboot.

-F Force fsck on reboot.

-c Cancel an already running shutdown. With this option it is of course not
possible to give the time argument, but you can enter a explanatory message
on the command line that will be sent to all users.

time When to shutdown.

If I remember correctly Xenserver [and vm esx] is based on either a debian or a red hat kernel so essentially everything that can be run from CLI on those kernels can also be run at CLI on Xenserver. I ran a xenserver in my home lab for some time and achieved a number customisations through bash commands/scripts. 'Shutdown' definitely has more functional options than initialising a different runlevel [to be honest, I did not know 'shutdown' was a valid command to linux either], have a look here: http://www.centos.org/docs/2/rhl-rg-en-7.2/s1-init-boot-shutdown-init.html

My two cents :)
