How can I run this script on startup, restart, and shutdown?

I'm using Ubuntu 11.10.

I've written a script, that synchronises a directory in ~ with a directory on /dev/sda4, using Unison. Before, I had this script running every five minutes with no problems, using crontab. Right now, I want to execute this script at startup, restart and shutdown only.

This is what the script looks like:

#!/bin/bash

unison -perms 0 -batch "/mnt/Data/Syncfolder/" "/home/myname/Syncfolder/"

I'd like the script to be run with mechanisms like Upstart, if possible. So I'd be happiest with a properly configured *.conf file in /etc/init.

Thanks in advance.

After a lot of searching and asking here, I managed to get it working:

Before doing the following, make sure that you aren't using unison-gtk (the Unison GUI) as well. I've had a situation in which unison and unison-gtk conflicted. Remove unison-gtk via sudo apt-get remove unison-gtk, and disable Unison's old config files by renaming the containing folder: mv .unison .unison.old

When you've done that, it's time to move on.

First I ran the script as a superuser. I did that because Unison needs to be run once when you create a new script, to make some logging files. The Upstart-scripts are probably run as root, so it's best to do that too when you run the script for the first time:

sudo su

unison -perms 0 -batch "/home/MyName/Syncfolder" "/mnt/Data/Syncfolder" >> /var/log/unison.log

exit

Then, I ran: sudo gedit /etc/init/unison.conf. I pasted the following, and saved the file:

description "My File Sync"

author "My Name"

env HOME=/home/MyName

start on runlevel [0123456]



pre-start script

    echo "Starts syncscript"

end script



post-stop script

    echo "Ends syncscript"

end script



exec unison -perms 0 -batch "/home/MyName/Syncfolder" "/mnt/Data/Syncfolder" >> /var/log/unison.log

Restart and you're done.
