Eksekusi Skrip saat logout pengguna (bukan pengguna root)

Saya di laboratorium universitas saya menjalankan ubuntu 12.10 dengan persatuan dan saya tidak memiliki root privilleges. Saya perlu menjalankan skrip saat logout. Apakah ini mungkin?

Catatan: ini mungkin duplikat dari pertanyaan ini , namun jawaban yang diberikan cukup samar dan tidak ada arahan khusus yang diberikan.

Ini adalah langkah demi langkah prosedur gnome_save_yourselfmetode. Ayo lakukan tes.

1. Simpan kode berikut sebagai ~/Desktop/execute_script_on_shutdown.sh (Dari http://www.linuxquestions.org/questions/linux-desktop-74/gnome-run-script-on-logout-724453/#post3560301 )

   #!/usr/bin/env python

   #This program runs a custom command/script just before gnome shuts 
   #down.  This is done the same way that gedit does it (listening for 
   #the 'save-yourself' event).  This is different to placing scipts 
   #in /etc/rc#.d/ as the script will be run before gnome exits.
   #If the custom script/command fails with a non-zero return code, a 
   #popup dialog box will appear offering the chance to cancel logout
   #
   #Usage: 1 - change the command in the 'subprocess.call' in 
   #           function 'session_save_yourself' below to be what ever
   #           you want to run at logout.
   #       2 - Run this program at every gnome login (add via menu System 
   #           -> Preferences -> Session)
   #

   import sys
   import subprocess
   import datetime
   
   import gnome
   import gnome.ui
   import gtk
   
   
   class Namespace: pass
   ns = Namespace()
   ns.dialog = None
   
   
   def main():
       prog = gnome.init ("gnome_save_yourself", "1.0", gnome.libgnome_module_info_get(), sys.argv, [])
       client = gnome.ui.master_client()
       #set up call back for when 'logout'/'Shutdown' button pressed
       client.connect("save-yourself", session_save_yourself)
       client.connect("shutdown-cancelled", shutdown_cancelled)
   
   
   def session_save_yourself( *args):
           #Lets try to unmount all truecrypt volumes
   
   
       #execute shutdowwn script
       #########################################################################################
       retcode = subprocess.call("bash /home/totti/Desktop/shutdown_script.sh", shell=True)
       ##########################################################################################
       if retcode != 0:
           #command failed  
           show_error_dialog()
       return True
   
   def shutdown_cancelled( *args):
       if ns.dialog != None:
           ns.dialog.destroy()
       return True
   
   
   def show_error_dialog():
       ns.dialog = gtk.Dialog("There was a problem running your pre-shutdown script",
                              None,
                              gtk.DIALOG_MODAL | gtk.DIALOG_DESTROY_WITH_PARENT,
                              ("There was a problem running your pre-shutdown script - continue logout", gtk.RESPONSE_ACCEPT))
       if ns.test_mode == True:
           response = ns.dialog.run()
           ns.dialog.destroy()
       else:
           #when in shutdown mode gnome will only allow you to open a window using master_client().save_any_dialog()
           #It also adds the 'Cancel logout' button
           gnome.ui.master_client().save_any_dialog(ns.dialog)
   
   
   
   #Find out if we are in test mode???
   if len(sys.argv) >=2 and sys.argv[1] == "test":
       ns.test_mode = True
   else:
       ns.test_mode = False
   
   if ns.test_mode == True:
       main()
       session_save_yourself()
   else:
       main()
       gtk.main() 

2. Jadikan itu dapat dieksekusi:

   chmod +x ~/Desktop/execute_script_on_shutdown.sh

3. Simpan yang berikut ini sebagai ~/Desktop/shutdown_script.sh

   #!/usr/bin/bash
   touch ~/Desktop/AAAAAAAAAAAAAAAAAAAAAAAAAAA  

4. Jalankan skrip utama

   bash ~/Desktop/execute_script_on_shutdown.sh

Sekarang Anda merasakan skrip menunggu sesuatu

1. Logout atau matikan OS Anda (Ubuntu)
2. Gabung

3. Periksa file bernama AAAAAAAAAAAAAAAAAAAAAAAAAAAdi desktop Anda.

   ls -l ~/Desktop/AAAAAAAAAAAAAAAAAAAAAAAAAAA

Jika Anda melihat file semuanya OK. Sekarang Anda dapat mengedit shutdown_script.shsesuai dengan kebutuhan Anda. Juga ingat untuk menjalankan execute_script_on_shutdown.shlogin saat ini (atau membuatnya otomatis dieksekusi pada saat startup).
