Edit: A new version of cmd-tutor is now available. See here.
There has been a gradually increasing influx into the linux community in recent years. The release of Vista has encouraged a lot of people to take the plunge and switch to linux. And while it is not any more essential to use the command line to manage your linux desktop today, many newcomers are interested in knowing what it is all about.
A lot of excellent tutorials are available, like this for example, but there were some requests for an interactive tutorial. Those who have tried the online ruby tutorial will know what I am talking about.
So, I wrote this tutorial in python. Keeping in line with Unix philosophy, the mechanism for presenting the lessons is kept separate from the lessons itself. Therefore it is easy to extend it by adding more lessons later. Currently there are 5 lessons that I have written. These would serve as a gentle introduction to a newcomer.
You have to be running linux to use this. You can download cmd_tutor here. The instructions to install are in the package. Briefly, you have to extract the package somewhere, navigate to the src directory from the terminal and then type 'python install.py install' with superuser privileges. Once installed, you can type 'cmd_tutor' in the terminal to start the tutor.
Any comments and suggestions will be welcome.

Pretty cool - I got caught up in lesson 3 when it wouldn't let me go "up" a directory, though. I wanted to see the creation of inner/innermost and then I backed out too far and couldn't get back to cmd_test (and it doesn't allow tab completion?):
To make a series of folders in one go, we can use mkdir like this mkdir -p
testthree/inner/innermost. The '-p' instructs mkdir to make the /innermost
folder with its parents.
Tutor>>> mkdir -p testthree/inner/innermost
--------------------------------------------------------------------------------
If you try to remove the testthree folder now with rmdir, you find that non-
empty directories cannot be removed like that. You can use the command rm
-r testthree instead. '-r' here stands for recursive, so that the top
folder and anything inside are removed.
