Script to move files, restart session and logout

[brunoais]

I'd like to ask for help making a script that does this:

• Copy files using rules:
  
  • Copy all files (and folders) that are in a folder in a pen drive to the home folder
  • Overwrite all files and folders that are in the home folder.
• Sessions:
  
  • After copying all the files restart user session so that all the preferences and appearance info is reloaded
  • OR
  • Apply the new user configurations immediately.
• Create a shortcut to open the logout script.
• Logout system
  
  • The system saves the session so that it can be continued later
  • All the files that are in the home folder
    
    • Must be copied to the pen drive and they
    • Must overwrite whatever it was there earlier.

I need this system because all my info at my school is not saved by them for me and doing this manually 3+ times a day takes too much time and is fastidious.
Need more info? Just ask

ADD:
NOTE:I can only work as a user.
