Download and launch an Elluminate session from the command line

We use Elluminate Live! for some of our meetings, and it has always bothered me that I have to launch the browser to use Elluminate especially for reoccurring meetings. So one afternoon I set out to fix this problem. I wrote the following script and have been using it for about a month now without any issues. You can set the parameters at the head of the script if you have a reoccurring meeting you want to use, or set the parameters at run time (or in an alias for multiple reoccurring meetings) if you need too.

The only prerequisite for this script is to have javaws installed an in your PATH.

#!/bin/bash

nick="NICKGOESHERE"
participant_password="PASSWORD"
leader_password="PASSWORD"
sid="SID"
output="/tmp/meeting.jnlp"
launch_on_download="true"
