I'm running Lubuntu 12.04. I have a shell script that tests for a network condition and need some way for it to pop up a notification in the GUI. The network testing part is done, but I need some help with the "pop up a notification in the GUI" part.

You can use the default notification daemon to give notifications with an icon.

Just add this line to the shell script where you want to give notification (with appropriate lines and paths).

notify-send -u critical -i <Icon-path> "<Heading>" "<Rest of the message>"

The package providing this is libnotify-bin.

@ThatJackElliott Did you replace <> with appropriate text? You need to remove "<" ">". Icon path is optional. Try this :

notify-send -u normal "Hello Jack Elliot" "This is a trial notification.\nWelcome to AskUbuntu\!"

-u can be low, normal & critical.

See man notify-send for more info.

In case of any problems, these are the packages in my system. They work excellently :

  • gir1.2-notify-0.7
  • libknotifyconfig4
  • libnotify-bin
  • libnotify-dev
  • libnotify0.4-cil
  • libnotify4
  • notify-osd
  • notify-osd-icons
  • python-notify
  • python-pyinotify
  • xfce4-notifyd
  • xfce4-notifyd
  • Hi, this one doesn't return anything. Just takes me back to the shell prompt. Dec 8, 2012 at 15:10
  • Okay, still no happiness: Dec 9, 2012 at 2:03
  • Run dpkg -l | grep notify-send and see if you get any output.

  • Nope, no output. Dec 10, 2012 at 21:33
  • @ThatJackElliott Sorry, I gave the wrong name. Try dpkg-query -l libnotify-bin OR dpkg -l | grep libnotify-bin. If no output, install libnotify-bin. Its available in the repos.

yeah you can do that with python. open your terminal and type

sudo apt-get install python-notify

Then write a program like this .

frank@august:~$ cat>not.py
import sys
import pynotify

if __name__ == "__main__":
    if not pynotify.init("icon-summary-body"):

    n = pynotify.Notification(
        "Hi Elliott",
        "welcome to askUbuntu!",
        ##dont remove the below line

save it with any name , for example noti.py for our case .

open your terminal and type python not.py

Then you will see

enter image description here

Hope that helps.

  • Hi, thanks for the suggestion, but I can't get this to work. When I run the script I get:jack@jack-Aspire-one:~/bin$ sh notify.py notify.py: 2: notify.py: import: not found notify.py: 3: notify.py: import: not found notify.py: 6: notify.py: Syntax error: "(" unexpected (expecting "then") jack@jack-Aspire-one:~/bin$ Dec 8, 2012 at 15:09
  • Wait, sorry, I didn't run the script correctly. I also can't figure out how to enter line breaks in this comment box, nor put the terminal results in a neat little box, so my responses are a bit of a mess. The python script is still returning an error: jack@jack-Aspire-one:~/bin$ python notify.py Traceback (most recent call last): File "notify.py", line 14, in <module> n.show() glib.GError: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Notifications was not provided by any .service files jack@jack-Aspire-one:~/bin$ Dec 8, 2012 at 15:13
  • have you installed python-notify ?
