Good article thanks. I'm stuck running commands in my login script in 10.3 and I'm having trouble with paths. Here's my test login hook script: #!/bin/sh /usr/bin/touch ~$1/Library/Preferences/thisisatest.txt exit 0 # end 'sudo testscript.sh yan' gives 'touch: /Users/yan/Preferences/thisisatest.txt: No such file or directory' The command works fine out of the script. I need to use a relative path to find the users home folder because some of my users are in /Users and some are in /network for networked home folder. Any ideas would be appreciated.

  $1 for a shell script is the first variable passed into the script. The Loginwindow passes in the username only, not "/Users/". I don't know why you got the error you did. I got:
  
  touch: ~james/Library/Preferences/thisisatest.txt: No such file or directory
  
  If I changed the script to:
  
  /usr/bin/touch /Users/$1/Library/Preferences/thisisatest.txt
  
  then it works.

  This works for me to, but what if users folders aren't always in located in /Users? This is a common with dynamically mounted home folders. The path to the users folder is sometimes /network/volumes.. etc.
  Can a solution be found to use relative paths here?
  
  Loginhook script runs as root.. Interestingly this command in the script works. Prefs management in Mac OS X is excellent.
  
  /usr/bin/sudo -u $1 /usr/bin/defaults write com.apple.print.PrintingPrefs DefaultPaperID -string "iso-a4"
