Run script when system shutdown

Question

Run script when system shutdown

Hi Community,

I know the possibility in snow leopard to execute a script during system boot by using a launchd script located in /Library/LaunchDeamons or ~/Library/LaunchAgents but how can I configure a script which become executed on a system shutdown?

Thanks in advance & Bye Tom

This cheap one works(image) on my Leopard. I tried a rc.shutdown.local file but it would not activate the script. Just got the shutdown to work. So, I threw this one together, fwiw and varying mileage. And it did say goodbye. The sudo usage on shutdown is covered by previous sudoers change by me.

But then it does what I want, and gets wiped out, so what did this accomplish? I guess it depends on the importance of one's script.

Hi,

I'm not sure if we are talking about the same ambition. I would like to run a script which changes some setting back to default for example during a shutdown and not to trigger a system shutdown. Like the K-scripts in Linux.

Thx & Bye Tom

Well then that is /etc/rc.local.shutdown that I believe you want. It won't trigger a shutdown, but on next restart, your commands will have been done. I just made a text file for /etc/rc.local.shutdown to cp from one file to another. Then I restarted manually and file was copied.

Hi,

there are many Google hits about a rc.shutdown.local but neither this type of script nor your version rc.local.shutdown works. I put a tiny command in it which should create a file in /tmp but the script seems not to become executed. I can run this script manually and it works but not at shutdown.

Any ideas?

Isn't /tmp cleared upon restart? Try putting the test file in $HOME/Desktop

Really? This could be the reason why I lost another test file I put to /temp a few days ago. I had no idea why this file was gone but now... 😉

I will have a try but now I'm in a discussion with a colleagau about a presentation we have tomorrow. But thanks this could be really the reason why it won't work...
