Unix/Linux tutorial for beginners

I’ve been looking around for good introductory material to commands which are common to Linux and Unix. I came across Unix Tutorial for Beginners. It’s not as detailed as other books or tutorials but for someone with little time or patience to study basic things. this seemed easy to read and understand.

Good points:

• It is written in an easy to read manner.
• The tutorials are short.
• It does not sound like a man page.
• There are some exercises in the early set of tutorials. Must be because it will enable readers to check if they really understood the lesson.
• The commands are very useful because most of them are the ones that I use regularly.

Some might think that the tutorials are too short to be meaningful but I think that the beauty of these tutorials is its use as a basis of where new users could begin digging deeper into Unix and Linux command line tools.
