Run bash scripts on login

[ingenious7]

Hi All,

I have written a script to help identify some physical security issues we are having in one of the labs at the school campus. It is a bash script that takes a photo of the use on login using the built in iSight camera.

I have tried to get this to run on login using the following

[code]sudo defaults write com.apple.loginwindow LoginHook /path/to/script[/code]

This doesn’t work. I am wondering if LoginHooks can only run AppleScripts or I can get my bash script to run.

Help greatly appreciated!

Thanks for the reply.

I’ve run the script as root, and it looks like there may be an issue.

This is the script I am running, and I am using an additional compiled script from [url]http://www.intergalactic.de/hacks.html[/url] called isightcapture.

[code]#/bin/bash
CallFile=/$(users)-$(date +%Y-%m-%d-%X).jpg

#echo $CallFile

/usr/local/bin/isightcapture $CallFile[/code]

Is there something wrong with the way I am coding this. I have even tried getting the script to do a mkdir to check it is running at login and nothing.

I have attempted to create a Login script using Mike Bombich’s LoginWindow Manager. Is there something I am missing?

I found this in the System.log. It seems login scripts are crashing.

[code]May 7 11:57:39 imac-computer /System/Library/CoreServices/mcxd.app/Contents/Resources/MCXLoginLogoutScriptTool: login: “loginscripts” in “com.apple.mcxloginscripts” is not a CFArray.
May 7 11:57:39 imac-computer /System/Library/CoreServices/mcxd.app/Contents/Resources/MCXLoginLogoutScriptTool: login: /Volumes/Macintosh HD/CaptureUser returned 5; exiting.
May 7 11:57:39 imac-computer crashdump[165]: MCXLoginLogoutScriptTool crashed[/code]

What is a CFArray? Why would the MCXLoginLogoutScriptTool be crashing.

Surely somebody easily runs login scripts on OS X 10.4.9?!?
😕

For anyone interested, I found the solution –

[code]sudo -s
echo ‘#!/bin/sh’ > /Library/Management/login.sh
echo ‘echo $1: `date` >> /tmp/login.log’ >> /Library/Management/login.sh
chmod a+x /Library/Management/login.sh
defaults write /var/root/Library/Preferences/com.apple.loginwindow LoginHook /Library/Management/login.sh[/code]

This is like a test. To make sure it is working, log in as a user, and enter

[code]cat /tmp/login.log[/code]

My script works perfectly now. I can have login photos taken via iSight camera, and sent straight back to my desk. A little Big Brotherish I think. Oh well.

I was sure I added it the same way. The only difference was that I renamed the script to login.sh. I don’t know if this made a difference or not.
