belgelemeIf you are new to Unix, you probably should go out and buy some books and do some reading. A lot of valuable information can also be found in the Debian Reference (http://www.debian.org/doc/user- manuals#quick-reference). This list of Unix FAQs (http://www.faqs.org/faqs/unix-faq/) contains a number of UseNet documents which provide a nice historical reference.
Linux is an implementation of Unix. The Linux Documentation Project (LDP) (http://www.tldp.org/) collects a number of HOWTOs and online books relating to Linux. Most of these documents can be in- stalled locally; just install the doc-linux-html package (HTML versions) or the doc-linux-text package (ASCII versions), then look in /usr/share/doc/HOWTO. International versions of the LDP HOWTOs are also available as Ubuntu packages.
