Hibernate from cron
Hi
I'm trying to make my media center (Ubuntu 10.10 with XBMC 10.1) hibernate automatically. I have added a task to cron (something like 50 22 * * * /etc/acpi/hibernate.sh) as root, and sudo crontab -l displays the task as expected. But when cron tries to run the task it logs the following error in syslog : grandchild (#xxxxx) failed with exit status 127 /etc/acpi/hibernate.sh does exist, and I can run it from a terminal as root. Any ideas ? Kim |

Hi Kim,
Try the following steps: 1. vi /hibernate 2. Put the following lines in this file: cd /etc/acpi ./hibernate.sh 3. Save the file and exit 4. chmod 755 /hibernate (Make it 777 if you want to make it available for all 5. In crontab put the following line 50 22 * * * /hibernate And the reason I can think of why you getting that message is because the path you have given in crontab is unable to locate the hibernate.sh file. I think the best way to work with cron is to create script and automate using cron. I hope this helps. |
Hi
Thanks for the reply, unfortunately that gave exactly the same result :scratch: I can run /hibernate as root. Kim |

Try this:
In crontab put the following line 50 22 * * * sh /hibernate |
Given that cron has a minimal env eg $PATH, maybe it's a cmd inside the script that has the issue? Ensure you are using the full path to all cmds & files referenced in the script.
Also, add Code:
set -xv |
Hi
Thanks for the answers. I have been examining the hibernate script, and it does call pm-hibernate without paths, so that probably is the cause of the 127 status. I'm not much for modifying the script as it is a system script. I have solved the problem by modifying a daemon, one I was using in the project anyway, to call hibernate.sh at the appropriate time, and it works. But thanks for the help anyway. Kim |
