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.

20 Linux Funny Commands

1. Command: sl (Steam Locomotive)

You might be aware of command ‘ls‘ the list command and use it frequently to view the contents of a folder but because of miss-typing sometimes you would result in ‘sl‘, how about getting a little fun in terminal and not “command not found“.

Install sl

[email protected]:~# apt-get install sl 		(In Debian like OS)
[email protected]:~# yum -y install sl 		(In Red Hat like OS)
Output
[email protected]:~# sl

sl command

This command works even when you type ‘LS‘ and not ‘ls‘.

恶作剧制作:

alias ls=sl

2. Command: telnet

No! No!! it is not as much complex as it seems. You would be familiar with telnet. Telnet is a text-oriented bidirectional network protocol over network. Here is nothing to be installed. What you should have is a Linux box and a working Internet.

3. Command: fortune

You're not my type.  For that matter, you're not even my species!!!
Future looks spotty.  You will spill soup in late evening.
You worry too much about your job.  Stop it.  You are not paid enough to worry.
Your love life will be... interesting.

7. Command: Cowsay

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

Install Cowsay

[email protected]:~# apt-get install cowsay 		(for Debian based OS)
[email protected]:~# yum install cowsay		(for Red Hat based OS)
Output
[email protected]:~# cowsay I Love nix 

 ____________
< I Love nix >
 ------------
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

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

[email protected]:~# fortune | cowsay 

 _________________________________________
/ Q: How many Oregonians does it take to  \
| screw in a light bulb? A: Three. One to |
| screw in the light bulb and two to fend |
| off all those                           |
|                                         |
| Californians trying to share the        |
\ experience.                             /
 -----------------------------------------
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

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.

apt-get install xcowsay
yum install xcowsay
Output
[email protected]:~# xcowsay I Love nix

Linux 装B之作酷炫小工具

xcowsay command

cowthink is another command just run “cowthink Linux is sooo funny” and see the difference in output of cowsay and cowthink.

apt-get insatll cowthink
yum install cowthink
Output
[email protected]:~# cowthink ....Linux is sooo funny
 _________________________
( ....Linux is sooo funny )
 -------------------------
        o   ^__^
         o  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

8. Command: 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.

[email protected]:~# yes I Love Linux

I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux

I Love Linux
I Love Linux
I Love Linux
I Love Linux

Note: (Till you interrupt i.e ctrl+c).

9. Command: 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.

Install toilet

[email protected]:~# apt-get install toilet 
[email protected]:~# yum install toilet
Output
[email protected]:~# toilet tecmint 

mmmmmmm                        "             m                               
   #     mmm    mmm   mmmmm  mmm    m mm   mm#mm          mmm    mmm   mmmmm 
   #    #"  #  #"  "  # # #    #    #"  #    #           #"  "  #" "#  # # # 
   #    #""""  #      # # #    #    #   #    #           #      #   #  # # # 
   #    "#mm"  "#mm"  # # #  mm#mm  #   #    "mm    #    "#mm"  "#m#"  # # #

It even offers some kind of color and fonts style.

11. Command: 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.

Install cmatrix

[email protected]:~# apt-get install oneko
[email protected]:~# yum install oneko

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.

12. Fork Bomb

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).

[email protected]:~# :(){ :|:& }:

13. Command: 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.

[email protected]:~# cd /tmp 
[email protected]:~# wget http://search.cpan.org/CPAN/authors/id/K/KB/KBAUCOM/Term-Animation-2.4.tar.gz

[email protected]:~# nice man woman

No manual entry for woman

There are certain other but these don’t work on all the system and hence not included in this article. Some of them are man dog , filter, banner, etc.

Have fun, you can say me thanks later :) yup your comment is highly appreciated which encourages us write more. Tell us which command you liked the most. Stay tuned i will be back soon with another article worth reading.






  1. Star Wars (telnet)

telnet是基于Telnet协议的远程登录客户端程序,经常用来远程登录服务器.但现在我们要用它来观看星球大战:

telnet towel.blinkenlights.nl

Linux 装B之作酷炫小工具


2. sl
我们经常用ls来列出当前目录下的所有文件,ls反过来也是一个有趣的命令,会出现一个移动的小火车.如果输入后提示"没有该命令",那就需要安装它。

apt-get install sl 		(In Debian like OS)
yum -y install sl 		(In Red Hat like OS)
sl

Linux 装B之作酷炫小工具

还可以给别人搞恶作剧:

 alias ls=sl

这样别人使用 ls 列出目录和文件的时候,却出现一个小火车,那滋味一定很酸爽哈哈哈哈!


3. fortune
这个命令会随机输出有趣的话,比如名言或笑话.同样需要先安装.

apt-get install fortune 	(for aptitude based system)
yum install fortune 		(for yum based system)
[email protected]:~$ fortune
There is no distinctly native American criminal class except Congress.
        -- Mark Twain

还有 fortune-zh , 输出的是中文内容,可能是一些诗词,也可能是一些有趣的句子。

3. Cowsay

这是一只可以说话的 ASCII Cow。

Linux 装B之作酷炫小工具

还可以把 cowsay 和 fortune 结合到一起使用:

[email protected]:~$ fortune -s | cowsay -f duck

这只cow不仅会说话,还会思考,不信你看:

                ||----w |
                ||     ||

还可通过cowsay -l 查看其它动物的名字然后-f跟上动物名如

[email protected]:~$ cowsay -f ghostbusters Who you Gonna Call
 ____________________

            \XXXXX--__/              __-- XXXX/
             -XXXXXXXX---------------  XXXXXX-
                \XXXXXXXXXXXXXXXXXXXXXXXXXX/
                  ""VXXXXXXXXXXXXXXXXXXV""

还可以这样玩,每次图形和文字都不一样:

[email protected]:~$ cowsay -f "$(ls /usr/share/cowsay/cows | sort -R | head -1)" "$(fortune -s)"

然后再补充一点实用的.那必然是 Vim 啊!
首先是vim插件,推荐使用 spf13/spf13-vim · GitHub 适合没时间折腾的懒人.
然后是浏览器的vim插件,firefox的Vimperator , chrome的Vimium ,彻底解放鼠标。
