So many options......which one i go guys......
ubuntu is the best ........??
Why books take REDHAT ??
Yes, Ubuntu is the best if you want to learn and you are a newbie. One of the main reason is because it has got the largest and the most active community in the linux fraternity. You can get solutions to your queries very quickly in ubuntu forums. Lets face it, if you are a newbie you will have problems with a lot of minor stuffs.
So go for ubuntu. Also, ubuntu is based on debian so you get a very large collection of softwares available in the repo. Once you get used to apt-get or aptitude, you will not want to look back. I have been using linux since Red Hat 9 [Thaks to the (I forgot the month ,2003) Digit Issue that gave out redhat 9 with installation guide.

] and I find deb packages in ubuntu the easiest to install. So trust me on this and go for ubuntu for your first linux experience. PM me two years from now to tell me your experiences
There are books for Ubuntu as well but since Red Hat Bible is published by Mcgraw Hill (??) it is readily available in India from Tata Mcgraw Hill (??) . Thats why when you talk books you mean the Redhat bible or the one on Fedora.
