Hi experts,

i'm working on a mixed network with a file server that us slackware linux (10.2) and some windows based clients.

I need to schedule a daily shutdown of the linux server.
Also, when special needs occurs, i want to cancel the shutdown for a specific day.

I know that this is possible using cron table.

I have a poor knowledge of linux, how can i do this?

Regards.

As root:

crontab -e

Edit crontab and add:

0 23 * * * /sbin/shutdown -r now

This will reboot the server at 2300 every day. In order to stop it, then just remove the line, and replace it afterwards.

HTH:)

I'm curious however, as to why you would wish to do this, unless you are saving electricity overnight?

Thanks for your post pjedmond.

I hate vi editing style, can i modify the crontab using mc?

P.S.:
The server is used for a few number of hours each day.
doing this, I'm saving energy and the overall lifetime of the server.
But most important, during the silence of night, the server is very noicy (my office has place in a family shared house (condominium).

You can edit the crontab with any editor you like:

[pje@bigserver root]# VISUAL=/usr/bin/nano
[pje@bigserver root]# export VISUAL
[pje@bigserver root]# crontab -e

if you like namo. I don't use mc, but I guess that it might be possible.

man crontab

for further details.

HTH:)

Obviously

/sbin/shutdown -h now

to make it shut down rather than reboot:)

Thankyou for the points:)
