scheduling poweroff using cron

akudewan · 11-16-2005, 12:52 AM

Hi,

I usually download stuff at night, as my ISP starts charging me only from 8:00AM. I wanted to schedule a poweroff before 8:00AM. I did a little google-ing and modified my /etc/crontab.

I just want to know if my entries are correct. Here is the file:

Code:

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file.
# This file also has a username field, that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user	command
17 *	* * *	root    run-parts --report /etc/cron.hourly
25 6	* * *	root	test -x /usr/sbin/anacron || run-parts --report /etc/cron.daily
47 6	* * 7	root	test -x /usr/sbin/anacron || run-parts --report /etc/cron.weekly
52 6	1 * *	root	test -x /usr/sbin/anacron || run-parts --report /etc/cron.monthly
# Shut down Azureus
46 7 * * * root killall -15 java
# Kill wine
45 7 * * * root killall -9 wine-preloader
# Power off
49 7 * * * root poweroff
#

Thanks,
-Aku

I guess killall -15 is blocked by wine-preloader it's why you send a killall -9. Kill -9 kills the program without any mean for him to save anything, so it is more dangerous..

Yes your cron are correct

Thanks, it worked perfectly today morning

I was using signal -9 for wine because it doesn't exit properly, and sometimes causes the disk to not unmount properly while powering off.
