[ILUG] Update Script

[Andrew Court]

This is very quick and dirty and not at all elegant, but it will give you an
idea of what you are looking for. I would also suggest reading a couple of
books on Linux and Shell scripting as the two go hand in hand.

Here is the script:

#!/bin/bash

NUM_OF_PKGS=`apt-get -V upgrade | wc -l`
SOUND_1=/home/someyoungguy/noupdates.wav
SOUND_2=/home/someyoungguy/WootUpdates.wav
SOUND_3=/home/someyoungguy/IRockUpgradeComplete.wav

if [$NUM_OF_PKGS == 0]
then
echo "There are no new updates" && mplayer $SOUND_2;

else {
$NUM_OF_PKGS [!= 0]
echo "There are $NUM_OF_PKGS available"
mplayer $SOUND_2

apt-get -V upgrade && mplayer SOUND_3
}
fi


What this does is it checks to see how many updates there are and counts
them, and plays a sound. If there are updates, then it tells you that, plays
another sound and then starts downloading the updates. WHen finished it
plays the third sound.

I would strongly recommend reading up on bash a bit. It is very powerful.
Just google for bash tutorial.
