I want to run some commands every time a user of an ubuntu 9.10 machine logs out or shuts down. What is the best way to do this? Every user uses gnome if that helps.

After some Googling I found How to run a script on logout? which says to add the script to $HOME/.bash_logout.

If that doesn't work, add

$HOME/.bash_logout

to /etc/gdm/PostSession/Default so it executes the logout script properly.

Seeing as before shutdown the user is logged off anyway, this should cover both bases.

If you don't want to be bound to a specific display manager then you can put your scripts under /etc/X11/Xreset.d/ which will be run as root every time you logout from an xsession.

For example: I want my virtualbox VM's to be on the savestate everytime a user logs out so I have a script that does that. #!/bin/bash su - $USER -c 'vboxmanage list runningvms | cut -d\" -f2 | xargs -I{} vboxmanage controlvm {} savestate'

If you are using KDE (I am using Ubuntu with kdm)

# From the kdm man page
#  http://manpages.ubuntu.com/manpages/oneiric/man1/kdm.1.html

/etc/kde4/kdm/Xreset - script to run as root after session exits

/etc/kde4/kdm/Xsession - script to run as user after login of user

/etc/kde4/kdm/Xsetup - script to run as root before the login dialog appears

/etc/kde4/kdm/Xstartup -  script to run as root before session starts

To test:

Open the appropriate file i.e. 

sudo emacs /etc/kde4/kdm/Xreset

Add a test command (create a file in my home directory)

touch  /home/dericbytes/this-file-was-created-by-xreset

Then I logged out, and back in again, and checked if the new file was created

ls /home/dericbytes/this*

Hmm..well if you google "linux run script on shutdown", the first result is a post on the Ubuntu forums with your answer:

chmod +x /etc/init.d/foo.sh

This will allow you execute the script as a program.

To have a script run at shutdown, use this technique:

sudo ln -s /etc/init.d/foo.sh /etc/rc0.d/K10rensa.sh
sudo ln -s /etc/init.d/foo.sh /etc/rc6.d/K10rensa.sh

As a sidenote, should I refrain from indulging people with answers when it is clear that they haven't even tried searching the Internet first (I'm new here..)?

You can probably use the ConsoleKit dbus interface.
