I want to learn linux

I want to learn linux OS but i dont have any software of it. Is it free or not?

Linux is free.. like in "free beer" Do some research, better still, do some downloading and try some live cd versions.

There are thousands of sites providing basic knowledge of LINUX such as :
http://yolinux.com/TUTORIALS/
http://www.comptechdoc.org/os/linux/use ... users.html
http://www.linuxquestions.org/
http://www.unixguide.net/linux/linuxshortcuts.shtml and many more...
really linux is easy to learn and is very good OS with high security; Most high configured server use LINUX on them ( One reason it's FREE )

All the best......

Thank you Janrocks and Harrysmith I hope I can learn Linux someday. Have a nice day to both of you.
