[Ubuntu 9.04] Plan a visual message

Intro

Ubuntu 9.04 has a new application that manages the notification system: notify-osd , allowing you to display visual messages at the time you want.

Getting started

First you must install the libnotify-bin package. To do this, type in a terminal:

sudo apt-get install libnotify-bin

To see if this works, type in the terminal:

notify-send Test "This is a test"

Normally, the message "This is a test" should be displayed

Preparing the script

Now that the software is operational,its time to create a script with the message that will be displayed at a given moment.
In your home folder, create a blank file named "recall.sh" (the ". sh" is essential, instead of "recall", you can put whatever you want)

In this file, write:

#!/bin/bash
notify-send "Message title" "Message"

and save.

Planning the execution of script

Now you need to run a command that will plan the display of message on-screen


Simply type in a terminal:

at -f recall.sh 19:30

This, run the script at 19:30.

If you want to run a particular day, enter:

at -f recall.sh  19:30 Jul 10

It will be displayed July 10 at 19:30

Adding an icon to the message

You will need an image or "icon" (PNG), and then edit the file recall.sh:

notify-send -i /path/of_image/image.png "Message title" "Message"
