for anyone interested the installation wiki page does appear to be out of date. The Full Linux install .bin file is no longer available for download.
New Question: All of the Alfresco installation guides for linux assume you're using some kind of GUI interface. Does anyone know of a step by step guide for those of us trying to install from command line?
Yes it looks like the wiki page you reference is a little out of date, in fact the page you reference is for Alfresco 1.4. The linux installer provided now does not have the ".bin" extension.
The Alfresco provided installation guide does look correct with regard to the file names for for installation on Linux.
