[ilugd] What's wrong with it???
hi guys, Can anyone find something interesting ? Well here is a shell script (kill.sh) : *#!/bin/bash id=`ps -ef | grep wget | grep -v grep | cut -c 10-15` if [ $id -eq 20698 ] then sleep 10m sh kills.sh else date kill_time poweroff fi * 1.It was around 4.AM i run it background.And checked the PID of wget, it was 20698. 2.I slept and wake up at 8.40 AM and checked again. 3.PC was still ON. No kill.sh was running .No Wget process was running as wget-log showed saved at 8.15AM. question : why didn't pc go OFF. 4.Again I start : sh kill.sh ... PC went OFF. (of course it must be) 5. Any comment(s) Cheers, Devesh. ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - February 22-24, 2008 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/

Any comment(s) I believe you're running this via cron. So, the user from whose cron entry you're running it, can issue poweroff command? Maybe you need to give full path to poweroff? -- Why can't I ever build character at a Miami condo or a casino somewhere? -- Calvin ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - February 22-24, 2008 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/

Hi , Well i knew pgrep and it is same as i wrote in single line.NO ISSUE about it. I logged in as 'root' so poweroff could be invoked and path was OK. Moreover the last point I again did 'sh kills.sh' PC WENT OFF. Well, name of script was kills.sh not kill.sh always. cheers, Devesh. ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - February 22-24, 2008 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
