I\'ve just been setting up a Ubuntu workstation and wanted to add some settings to eclipse.ini. When I searched for the file I found:
You probably have already found this out, chances are when you installed Eclipse the installation created (or you did manually) a file /usr/bin/eclipse which if you check it probably looks like the following:
#!/bin/sh
export ECLIPSE_HOME="/opt/eclipse"
$ECLIPSE_HOME/eclipse $*
especially if you followed instructions similar to the ones like these on If-not-true-then-false
On the other hand if you have installed from a package, I suspect you will find that eclipse ends up in /usr/bin, most likely a symbolic link to /usr/lib/eclipse/eclipse (or at least I found it on my Fedora system after using yum to install eclipse).
