Linux is fun! Huhhh. OK so you don't believe me. Mind me at the end of this article you will have to believe that Linux is actually a fun box.
Linux 是非常有趣的，别不相信 —— 看完这篇文章，你一定会发现 Linux 系统神奇的用法。

terminal.

## rev (Reverse)

It reverse every string given to it, is not it funny.

## script

shell 脚本
OK fine this is not a command and a script but it is nice.

## cowsay

An ASCII cow in terminal that will say what ever you want.

How about pipelineing 'fortune command', described above with cowsay?

Note: '|' is called pipeline instruction and it is used where the output of one command needs to be the input of another command. In the above example the output of 'fortune' command acts as an input of 'cowsay' command. This pipeline instruction is frequently used in scripting and programming.

xcowsay is a graphical program which response similar to cowsay but in a graphical manner, hence it is X of cowsay.
xcowsay 是一个图形程序，其效果类似于 cowsay，但是是以图形方式显示说话的牛。

cowthink is another command, just run cowthink Linux is sooo funny and see the difference in output of cowsay and cowthink. cowthink 是另一个命令，你可以执行 cowthink Linux is sooo funny 看看它和 cowthink 的输出差异。

## yes

It is funny but useful as well, specially in scripts and for System Administrators where an automated predefined response can be passed to terminal or generated.

Note: (Till you interrupt i.e Ctrl+C).

## toilet

What? Are u kidding, huhh no! Definitely not, but for sure this command name itself is too funny, and I don't know from where this command gets it's name.

It even offers some kind of color and fonts style.

Note: Figlet is another command that more or less provide such kind of effect in terminal.

## cmatrix

You might have seen Hollywood movie 'matrix' and would be fascinated with power, Neo was provided with, to see anything and everything in matrix or you might think of an animation that looks alike Hacker's desktop.

yum 上似乎找不到，可以使用源码编译安装。

## oneko

OK so you believe that mouse pointer of Linux is the same silly black/white pointer where no animation lies then I fear you could be wrong. oneko is a package that will attach a "Jerry" with you mouse pointer and moves along with you pointer.

Note: Once you close the terminal from which oneko was run, jerry will disappear, nor will start at start-up. You can add the application to start up and continue enjoying.

## while

The below while command is a script which provides you with colored date and file till you interrupt (Ctrl+C). Just copy and paste the below code in terminal.

Note: The above script when modified with following command, will gives similar output but with a little difference, check it in your terminal.

## espeak

Just Turn the Knob of your multimedia speaker to full before pasting this command in your terminal and let us know how you felt listening the god's voice.

## aafire

How about fire in your terminal. Just type aafire in the terminal, without quotes and see the magic. Press any key to interrupt the program.

## bb

First install apt insatll bb and then, type bb in terminal and see what happens.

## ASCIIquarium

How it will be to get an aquarium in terminal.

And finally run asciiquarium or /usr/local/bin/asciiquarium` in terminal without quotes and be a part of magic that will be taking place in front of your eyes.

## Fork Bomb

Fork 炸弹
This is a very nasty piece of code. Run this at your own risk. This actually is a fork bomb which exponentially multiplies itself till all the system resource is utilized and the system hangs. (To check the power of above code you should try it once, but all at your own risk, close and save all other programs and file before running fork bomb).
