Use of login or logout events

$1 should return the username. Hooks run with root rights, but use the variable to specify user.

Hey you learn something new every day I suppose. I didn't know that was there, but I do know it hasn't always been there. Apple just sneakily added that in when I wasn't looking. :)

Casper will do the same thing but I believe it uses $3. There is a manual somewhere that explains all of this.

So I have given this a run on a computer I know works every time, and indeed the next time it logged in, it was recorded. Then I tried it on a machine we were having issues with, and I still get no record in JSS, nor result from the script running though I can see stuff like startup which occurred earlier in the day. Any other idea what could be happening?

Look at the jamf log on the local machine having issues, does it give any clues?

Here is an example of the script I am trying to run:
#!/bin/bash
# Written by -------
# See if the LaunchServices LSHandlers key is set
defaults read com.apple.LaunchServices LSHandlers > /dev/null 2>&1

if [ $? -eq 0 ]
then

# get the current LSHandlers defaults=defaults read com.apple.LaunchServices LSHandlers

# write the new LSHandlers, replacing acrobat pro with acrobat reader defaults write com.apple.LaunchServices LSHandlers "'${defaults/com.adobe.acrobat.pro/com.adobe.acrobat.reader}'"
fi

Log in/out hooks run as the root user, so if they are modifying any user level stuff the root user's home directory gets modified not the user being logged in.

Can you provide some specific examples of a script or whatever you are using to to this? Casper has a built in switch that will use $3 as the currently logged in user, but only if Casper runs it and only if it runs it as a log in hook.

I remember $3 is used to designate target volume when running scripts during imaging, but that was back when we used NetRestore.
