Our users often recommend useful sites in response to a question. But the recommendations seem to get lost among our threads only to get re-recommended later. I will try to collect these here. I won't duplicate sites mentioned in [thread=13774]Unix Tutorials/Programming Tutorials/Shell Scripting Tutorials[/thread], so check that FAQ thread as well. I have decided to move references to the Usenet Unix Faq to a separate thread (USENET Unix FAQS) so they don't overwhelm this thread. I will reject sites that seem easy to find, such as www.sun.com or www.samba.org. This still leaves hundreds, perhaps even thousands of sites. I will use my best judgement in an attempt at constructing a compact but useful list.
