Full Discussion: cronjob Command for Shutdown
Operating Systems Linux Red Hat cronjob Command for Shutdown Post 302586024 by admin_xor on Friday 30th of December 2011 02:30:43 AM
Old 12-30-2011
You can run the cron job at 5:55 PM with the following modifications. It's better if you could save the script in a file and make it executable and run it in cron.
Code:
#!/bin/bash

# initshut.sh file
/bin/cat /root/machines | while read sys; do
   # let's put it in the background and move on to the next machine
   ( /usr/bin/ssh root@$sys '/sbin/shutdown -h +10 "The system is going down after 10 minutes. Please save your work and log off before that. --Admin"' ) &
done

Please note the single and double quotes. Without their proper usage, the command will not be executed.

Then, make a crontab entry like this:
Code:
55 17 * * * '/root/initshut.sh >/dev/null 2>&1'

NAME

       apticron - Generate a mail listing packages which are pending an upgrade

SYNOPSIS

       apticron [--cron]

DESCRIPTION

       apticron is a shell script which generates a mail with a list of all packages currently pending an upgrade, as well as summary of changes -
       using apt-listchanges - to a configurable Email address.

       apticron is mainly intended for automatic notification of pending security updates but can also be used	in  many  other  situations  where
       timely updates are necessary.

       The --cron option is only meant to be used when invoked by cron in order to run no more than once a day.

FILES

       /etc/apticron/apticron.conf
	      Configuration file, Email address to mail and profile for use with apt-listchanges are configurable.

       /etc/cron.d/apticron
	      Cron job for executing apticron daily.

       /etc/cron.daily/apticron
	      Fallback cron script for executing apticron (if no crond running or system down at designated time).

       /var/lib/misc/apticron.cron
	      Time stamp file used by apticron when invoked with --cron option.
