My Attitude Toward Linux Shell

I must be an extremely patient user of Linux, for I have been trying to install all versions of Linux distributions lately, and getting used to the shell commands.

I also read some books on the subject. To be honest, it is true that the command lines are more efficient, and this can be verified by the following calculation:

Suppose a mouse have 3 keys, and the keyboard ten times more. The three key mouse can generate actions 3^2 when clicked 2 times, while the keyborad 30^2. Come on, no matter we clicked the keyboard or the mouse, we just clicked 2 times.
