This article will describe Login and Logout hooks and how to create them.
__FORCETOC__
==Create Log In/Out Hook==
Before proceeding, note that if you do not have a password, you will need to create a password on your account for this to work.

#Open Terminal (Applications/Utilities).
#In the Terminal window, for Log In Hooks type <code>sudo defaults write com.apple.loginwindow LoginHook '''/path/to/script'''</code> Where '''/path/to/script''' is the full path to the script that you want to execute when a user logs in—it doesn't have to be in the user's Home directory.
#In the Terminal window, for Log Out Hooks type <code>sudo defaults write com.apple.loginwindow LogoutHook '''/path/to/script'''</code> Where '''/path/to/script''' is the full path to the script that you want to execute when a user logs in—it doesn't have to be in the user's Home directory.
#This modifies the '''/var/root/Library/Preferences/com.apple.loginwindow''' file.
#Type your password at the prompt, then press Return.

==Remove Log In/Out Hook==
Before proceeding, note that if you do not have a password, you will need to create a password on your account for this to work.
#Open Terminal (Applications/Utilities).
#In the Terminal window, for Log In Hooks type <code>sudo defaults delete com.apple.loginwindow LoginHook '''/path/to/script'''</code> Where '''/path/to/script''' is the full path to the script that you want to execute when a user logs in—it doesn't have to be in the user's Home directory.
#In the Terminal window, for Log Out Hooks type <code>sudo defaults delete com.apple.loginwindow LogoutHook '''/path/to/script'''</code> Where '''/path/to/script''' is the full path to the script that you want to execute when a user logs in—it doesn't have to be in the user's Home directory.
#This modifies the '''/var/root/Library/Preferences/com.apple.loginwindow''' file.
#Type your password at the prompt, then press Return.

==Examples==
===Clear Home Directory on Log Out===
This script is called '''clrlogout.sh''' used in a Lab and deletes all user account folders that are not named "admin".

#!/bin/bash
if [ $1 = "admin" ]
then exit 0
fi

#Deletes the user account and its local home directory
dscl . -delete /Users/$1 #deletes the user from System Preferences
rm -R /Users/$1 #deletes the user's local home directory

exit 0

This script can be amended to not delete other user home directories as well. This script is placed in the folder '''/Library/Scripts/Company'''. When applying it as a logout hook, type the command in Terminal:

<code>'''sudo defaults write com.apple.loginwindow LoginHook /Library/Scripts/Company/clrlogout.sh'''</code>
