For multi-user access, you’ll probably want to install this in the system-wide directory:
so, as root, copy the file eclipse-SDK-22.214.171.124-linux-gtk.tar.gz to /usr/local and uncompress it:
# tar xzf eclipse-SDK-126.96.36.199-linux-gtk.tar.gz
This action creates the directory eclipse and the executable is the file eclipse within that directory. You only need to make it accessible for your execution by adding it to the PATH variable with a statement like:
added to a system-wide environment settings file or to your local file ~/.bash_profile.
