Move the archive to /usr/local or wherever you want it. If you want all your computer users to access Eclipse it's preferred doing so in /usr/local, using the sudo way:
$ sudo mv eclipse-SDK-3.0M6-linux-gtk.zip /usr/localNext you need to extract all the Eclipse files:
$ cd /usr/local $ sudo unzip eclipse-SDK-3.0M6-linux-gtk.zipThis will extract all files in a subdirectory called eclipse in your current working directory. Basically, the installation is finished now.
