How to create a logon script to delete folder, subfolders and contents when a user logs on ?

Question

I need to create a logon script which will delete a folder, subfolder and contents when a user logs on. I have no experience with scripting so any pointers you can give would be much appreciated.
Thanks

depending on how you have thing set up, it might be easier to make a LaunchAgent to handle this.  do this:
copy the text below into a text editor
save it as a plain text file in /Library/LaunchAgents with the file name "user.startup.folderDeleter.plist" (the name doesn't matter so much, but the 'plist' extension is required)
load the plist into launchd by restarting the machine or by opening terminal and running the command launchctl load /Library/LaunchAgents/user.startup.folderDeleter.plist
This will delete the folder any time any user logs in.  You could also expand this to delete the folder periodically (once a day, for instance) if that would be helpful.
Note, this file must be saved as plain text. apps like TextEdit sometimes default to making rich text files which will not work.  Either download a programmer's text editor like TextWrangler, or make sure that TextEdit is using plain text (if the window has a formatting toolbar it's using rich text;  select "Make Plain Text" from the Format menu).
copy the text below:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
          <key>Label</key>
          <string>user.startup.folderDeleter</string>
          <key>RunAtLoad</key>
          <true/>
          <key>ProgramArguments</key>
          <array>
                    <string>osascript</string>
                    <string>-e</string>
                    <string>tell application "Finder" to delete folder "Final Cut Express Data" of folder (path to preferences from user domain)</string>
                    <string>-e</string>
                    <string>tell application "Finder" to empty trash</string>
          </array>
</dict>
</plist>
