परिचय
स्क्रिप्ट बलो डब से विशिष्ट संदेशों के लिए बाधित-संचालित मतदान का उपयोग करता है, और जब भी यह शटडाउन / रिबूट के लिए अनुरोध देखता है, तो यह परीक्षण करेगा कि पैकेज प्रबंधक जैसे कि dpkgया aptचल रहे हैं या नहीं । यदि वे चल रहे हैं, तो शटडाउन अनुरोध रद्द कर दिया जाएगा।
सेट अप
चूँकि आपने उल्लेख किया है कि आपका मित्र कमांड लाइन को नहीं छूना चाहता है, तो आपको या तो उसकी मशीन में शशिश करने की आवश्यकता होगी, या आकर इसे मैन्युअल रूप से इंस्टॉल करना होगा।
स्वतः व्यवस्था
mkdir $HOME/bin- स्क्रिप्ट स्रोत की प्रतिलिपि बनाएँ, नामित फ़ाइल में सहेजें
preventShutdown.sh
- स्क्रिप्ट निष्पादन योग्य होनी चाहिए।
chmod +x $HOME/bin/preventShutdown.shऐसा करने के लिए उपयोग करें
- लॉग इन करने के लिए रूटीन की सूची में एक स्क्रिप्ट जोड़ें। लॉगिन / स्टार्टअप एप्लिकेशन का उपयोग करके यूनिटी / सूक्ति के लिए लॉग इन करें या

# Basic idea : This runs dbus-monitor which waits for
# "RebootRequested" memberf from com.canonical.Unity.Session ,
# which apprears only when the user clicks the shutdown option
# from the Unity's top right drop down box. Why RebootRequested ?
# Because this message is guaranteed to pop up once user presses
# the shutdown button.
# The while loop with read command does the big job.
# dbus-monitor sends initial message , so we want to filter only
# The output that contains the string we need, hence the case...esac
# structure employed here. Once we get the proper message.
# we check whether update-manager or package managers are running
# If there is one instance, then call CancelAction method
# and send notification to the user.
# Both dbus-monitor and while loop run continuously. This
# can be launcher as script in `/etc/rc.local` or `/etc/rc2.d`
# or preferably (!) in `/etc/xdg/autostart/` .
# Here is sample /etc/xdg/autostart/preventShutdown.desktop file
#
# [Desktop Entry]
# Type=Application
# Name=Prevent-Update
# Exec=/home/$USER/bin/preventShutdown.sh
# OnlyShowIn=GNOME;Unity;
# Terminal=false
#
# Remember to make this file as well as script be root-owned with
# chmod +x /path/to/Script.
# It is preferred to store the script in user's personal $HOME/bin
# folder.
# Make sure to edit $HOME/.profile file to include that into $PATH
# variable
