hello, it's my first time to use linux os...im given 1 month to familiarize linux using the command line interface...do you have any tutorial for newbs that i could use for my self study...thank you...

There's a bunch of beginner sites if you google around, like:

http://www.linuxgeek.net/beginners/
or
http://www.reallylinux.com/

Why 1 month?? (Homework?)

Get the Bash Guide for Beginners by Machtelt Garrels--it is at http://tldp.org

Advice: install Linux, and don't install X.

If you mean this to be an answer to the OP, then it makes no sense. With no X installed, how would you research CLI tutorials, manuals, etc.?

Or perhaps you mean don't install X, so you are forced to use the CLI??? OK--if you want to learn to walk, don't buy a car...

im currently using the tutorials of http://www.linuxcommand.org/wss0070.php...and is working very well. uhhmmm. im already working and we have a project that will begin this june using c++ and linux as it's environment. im a java programmer and im not yet familiar with c/c++ and linux.

So--you wnat to learn bash and C ..and C++.. all at the same time......Sounds like a recipe for brain damage....

One good book is "Beginning Linux Programming" from Wrox

http://www.tldp.org/guides.html

Indeed, having no X on the system means you are FORCED to use the CLI. You are FORCED to learn, or you can't use your system. How you'd research CLI tutorials? Who needs CLI tutorials? People learned their way around the command line long before millions of useless articles with the exact same topic appeared : "LOL! most 10 used commands in linux!! gots to read this if u r newbie from windows roflmfao". Such tutorials are harmful. First of all people who are absolutely new to linux write them because they need to prove to themselves they have "skills", and 2nd of all they are "minimal" from an informative point of view. How are you going to research manuals? Easy. Don't know how to use `ls`?

Etc. RTFM works, well.

Pretty poor attitude. Even Slackware has had massive documentation packages similar/same to content on tldp.org for as long as I can remember.

If you're unfamiliar with *nix, most man pages aren't much help.
