I am a newbie and followed the instructions of the site: http://sejalivre.org/instalando-o-java-6-update-30-no-ubuntu/ in order to install Java and some proprietary software based on Java on my Ubuntu 11.10 box.
According to that site, I should use the command:
sudo apt-get install openjdk-6-jre icedtea-plugin
to install Java and the proprietary software.
I did that, but started to wonder if that script is clean and not some malware... For my peace of mind I want to remove everything that was installed with that command.
