The best approach is to get the tarball and install it in a directory accessible system wide.

I installed it in /usr/local/LimeWire and it seems to run ok as long as you cd to that directory (a java thing). The other gotcha is that the runLime.sh file must have execute attribute.

Fix this with this command:

#chmod a+x /usr/local/LimeWire/runLime.sh

After this any user can run LimeWire from their account with the following commands:

cd /usr/local/LimeWire
./runLime.sh

For java to work right you need to be in the directory where the program is. That is why you need the cd command.

I made it easy for my users by creating bash script /usr/local/bin/limewire with the following commands:

#!/bin/bash
cd /usr/local/LimeWire
./runLime.sh
exit

Also don't forget to make it executable:

chmod a+x /usr/local/bin/limewire

After this, users can start LimeWire with the command:

limewire
