I have been with Windows for long and don't know linux. Where can i learn basic commands in linux to help me manage server (CentOs)?

Here is a pretty basic overveiw of most linux commands. http://www.ss64.com/bash/

I think one of the things that can be difficult to get to grips with is the directory structure. Like "where is every thing?" and "where should I put this?".

Here is a starter: http://www.tuxfiles.org/linuxhelp/linuxdir.html

The distribution you use will have variations and its own way of doing things.

If you really want to get to grips with Linux, install it on your desktop. Ubuntu should make it relatively painless, but you'll end up in the command line whatever version you use.

And that is where you want to be after all...

You can also take a look at one of our threads: http://www.hostingdiscussion.com/har...-commands.html

Try this url => http://www.unixguide.net/linux/linuxshortcuts.shtml for your requirement

google Linux Comands as well. This could help you with your search. But forums are also a good place to find information too. I wish you the best in luck on this.

Search on the forum..we have a thread going on regarding simple commands and their uses and examples.
