Change frequency of shutdown's broadcast message?

fogwatch · 10-28-2009, 07:26 PM

Hello
I start shutdown -h 22:30 & as part of boot. The problem is that terminals thereafter get contaminated with stupid messages like:

Broadcast message from root (Thu Oct 29 10:30:05 2009):

The system is going DOWN for system halt in 780 minutes!

How do I change the frequency of shutdown's broadcast message?

Do you know why "shutdown" is printing that message? Because you told it to. Computers are famous for doing exactly what you tell them. Supposedly that's a "good thing".

Code:

$ man shutdown

If you don't want the message, then put the scheduled shutdown in cron instead. Example:

Code:

25 22 * * * root shutdown -h +5

This will cause a warning to be printed at 22:25 and a shutdown at 22:30.

Code:

30 22 * * * root shutdown -h now

This will cause a shutdown at 22:30 with a warning immediately prior.
