hmm... I think you're using windows... so you should start by searching live-on-cd linux, like knoppix. You can download it from anythere like *.iso and make a bootable cd (I think you know who is nero). Then you can start study in unix. You should start by running console and typing commands like "ls", "cd" and "pwd" to navigate in your unix. If you done you should try others commands. Type "ls /bin" to see a list of basic commands. If you don't know what command what do, type: "yourcommand --help" or "man yourcommand". Next step is other commands (advance). You can get list by typing: "ls /usr/bin", then try theese commands. You should study very hard and please... don't hurry. Then you think you enought smart in unix - you can run mozila (or other browser), then goto
www.unix.com (this site is the best!
) and try to search everything you need, ask questions, leave posts... after that, you're unix expert!
