Hi all; Linux experts already know about these sites, but I only found them this morning. Very well written, easy to read from a NIT. http://www.tldp.orgThe Linux Documentation Project http://www.tldp.org/HOWTO/HOWTO-INDEX/howtos.html http://tldp.org/LDP/intro-linux/html/sect_03_01.html A nice summary of commands http://www.er.uqam.ca/nobel/r10735/unixcomm.html Great info on filesystem http://www.pathname.com/fhs/pub/fhs-2.3.html Hope someone else finds these interesting. Steve
