Hey!
Do you guys know of a good site that can explain all the Unix commands... I have been using Unix f�r almost 6 months but still have probelms with things like -u -U -g -G -R -T bla bla bla bla
thanks!
Dave
You're in luck, you don't even need a site, the instructions ought to exist on your UNIX machine. Indeed nobody could hope to memorize them all 
Try "man commandname" to bring up instructions for the command, including what paramaters it uses. Arrow keys or spacebar scrolls through the text, q quits.
you need to have a command efter "man" commando.. t.ex man ls
what i am looking f�r is just an explenation of all the switches....
there must be a sight that gives a overview of these? 
The switches are specific to each program - that's why we need online manual pages. Some are long "ls --color=tty", some are short "ls -l" and some are even shorter "dd if=/dev/zero". But doesn't mean the same thing to different programs, unless the author of the program has specifically done so.
