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
   root@tecmint:~# apt-get install sl (In Debian like OS)root@tecmint:~# yum -y install sl (In Red Hat like OS)
   Output
   root@tecmint:~# sl
   650) this.width=650;" class="size-full wp-image-3010" src="http://www.tecmint.com/wp-content/uploads/2013/05/sl.png" alt="sl funny command" height="387" width="620" onabort="" onblur="" onchange="" onclick="" ondblclick="" onerror="" onfocus="" onkeydown="" onkeypress="" onkeyup="" onmousedown="" onmousemove="" onmouseout="" onmouseover="" onmouseup="" onreset="" onresize="" onselect="" onsubmit="" onunload="" style="padding: 0px; margin: 0px; vertical-align: top; border: none;">
   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.
   root@tecmint:~# telnet towel.blinkenlights.nl
   650) this.width=650;" class="size-full wp-image-3011" src="http://www.tecmint.com/wp-content/uploads/2013/05/telnet.png" alt="telnet command" height="387" width="620" onabort="" onblur="" onchange="" onclick="" ondblclick="" onerror="" onfocus="" onkeydown="" onkeypress="" onkeyup="" onmousedown="" onmousemove="" onmouseout="" onmouseover="" onmouseup="" onreset="" onresize="" onselect="" onsubmit="" onunload="" style="padding: 0px; margin: 0px; vertical-align: top; border: none;">
   telnet command
3. Command: fortune

what about getting your random fortune, sometimes funny in terminal.
Install fortune
root@tecmint:~# apt-get install fortune (for aptitude based system)root@tecmint:~# yum install fortune (for yum based system)
root@tecmint:~# fortuneYou'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.

4. Command: rev (Reverse)

   root@tecmint:~# rev123abc cba321 xuniL eb ot nrobborn to be Linux
5. Command: factor
   Time for some Mathematics, this command output all the possible factors of a given number.
   root@tecmint:~# factor5 5: 5 12 12: 2 2 3 1001 1001: 7 11 13 5442134 5442134: 2 2721067
6. Command: script
   OK fine this is not a command and a script but it is nice.
   root@tecmint:~# for i in {1..12}; do for j in $(seq 1 $i); do echo -ne $i—$j=$((i*j))\t;done; echo;done 1—1=1 2—1=2 2—2=4 3—1=3 3—2=6 3—3=9 4—1=4 4—2=8 4—3=12 4—4=16 5—1=5 5—2=10 5—3=15 5—4=20 5—5=25 6—1=6 6—2=12 6—3=18 6—4=24 6—5=30 6—6=36 7—1=7 7—2=14 7—3=21 7—4=28 7—5=35 7—6=42 7—7=49 8—1=8 8—2=16 8—3=24 8—4=32 8—5=40 8—6=48 8—7=56 8—8=64 9—1=9 9—2=18 9—3=27 9—4=36 9—5=45 9—6=54 9—7=63 9—8=72 9—9=81 10—1=10 10—2=20 10—3=30 10—4=40 10—5=50 10—6=60 10—7=70 10—8=80 10—9=90 10—10=100 11—1=11 11—2=22 11—3=33 11—4=44 11—5=55 11—6=66 11—7=77 11—8=88 11—9=99 11—10=110 11—11=121 12—1=12 12—2=24 12—3=36 12—4=48 12—5=60 12—6=72 12—7=84 12—8=96 12—9=108 12—10=120 12—11=132 12—12=144
7. Command: Cowsay
   An ASCII cow in terminal that will say what ever you want.
   Install Cowsay
   root@tecmint:~# apt-get install cowsay (for Debian based OS)root@tecmint:~# yum install cowsay (for Red Hat based OS)
   Output
   root@tecmint:~# cowsay I Love nix ____________< I Love nix > ------------ \ ^__ \ (oo)_______ ()\ )/\ ||----w | || ||
   How about pipelineing ‘fortune command‘, described above with cowsay?
   root@tecmint:~# 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 xcowsayyum install xcowsay
   Output
   root@tecmint:~# xcowsay I Love nix
   650) this.width=650;" class="size-full wp-image-3012" src="http://www.tecmint.com/wp-content/uploads/2013/05/xcowsay.png" alt="install xcowsay" height="387" width="620" onabort="" onblur="" onchange="" onclick="" ondblclick="" onerror="" onfocus="" onkeydown="" onkeypress="" onkeyup="" onmousedown="" onmousemove="" onmouseout="" onmouseover="" onmouseup="" onreset="" onresize="" onselect="" onsubmit="" onunload="" style="padding: 0px; margin: 0px; vertical-align: top; border: none;">
   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 cowthinkyum install cowthink
   Output
   root@tecmint:~# 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.
   root@tecmint:~# yes I Love LinuxI Love LinuxI Love LinuxI Love LinuxI Love LinuxI Love LinuxI Love LinuxI Love LinuxI Love LinuxI Love LinuxI Love LinuxI Love LinuxI 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
   root@tecmint:~# apt-get install toilet root@tecmint:~# yum install toilet
   Output
   root@tecmint:~# 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.
   root@tecmint:~# toilet -f mono12 -F metal Tecmint.com
   650) this.width=650;" class="size-full wp-image-3013" src="http://www.tecmint.com/wp-content/uploads/2013/05/toilet.png" alt="install toilet command" height="387" width="620" onabort="" onblur="" onchange="" onclick="" ondblclick="" onerror="" onfocus="" onkeydown="" onkeypress="" onkeyup="" onmousedown="" onmousemove="" onmouseout="" onmouseover="" onmouseup="" onreset="" onresize="" onselect="" onsubmit="" onunload="" style="padding: 0px; margin: 0px; vertical-align: top; border: none;">
   toilet command
   Note: Figlet is another command that more or less provide such kind of effect in terminal.
10. Command: 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.
    Install cmatrix

    cmatrix command
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
    root@tecmint:~# apt-get install onekoroot@tecmint:~# yum install oneko
    Output
    root@tecmint:~# oneko
    650) this.width=650;" class="size-full wp-image-3015" src="http://www.tecmint.com/wp-content/uploads/2013/05/oneko.png" alt="install oneko" height="387" width="620" onabort="" onblur="" onchange="" onclick="" ondblclick="" onerror="" onfocus="" onkeydown="" onkeypress="" onkeyup="" onmousedown="" onmousemove="" onmouseout="" onmouseover="" onmouseup="" onreset="" onresize="" onselect="" onsubmit="" onunload="" style="padding: 0px; margin: 0px; vertical-align: top; border: none;">
    oneko command
    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.

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

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

650. this.width=650;" src="http://mmbiz.qpic.cn/mmbiz/MOwlO0INfQrfZln4Pg14Y4FBfS9WNpSSfcDwOicR0BoRWE4FToBMtMwsjoLp1je1seWPAqgoRHhHeF8LW7wyicoQ/640?wx_fmt=jpeg&wxfrom=5&wx_lazy=1" class="origin_image zh-lightbox-thumb lazy" alt="640?wx_fmt=jpeg&wxfrom=5&wx_lazy=1" width="690" onabort="" onblur="" onchange="" onclick="" ondblclick="" onerror="" onfocus="" onkeydown="" onkeypress="" onkeyup="" onmousedown="" onmousemove="" onmouseout="" onmouseover="" onmouseup="" onreset="" onresize="" onselect="" onsubmit="" onunload="" style="padding: 0px; margin: 0px; vertical-align: top; border: none; width: auto; height: auto;">

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

650. this.width=650;" src="http://mmbiz.qpic.cn/mmbiz/MOwlO0INfQrfZln4Pg14Y4FBfS9WNpSSYYiaEq1iczlkFOuibicKTuJZbdDLujXfPx5f8yVF4S5t2MnX5Mia8VImC8g/640?wx_fmt=jpeg&wxfrom=5&wx_lazy=1" class="origin_image zh-lightbox-thumb lazy" alt="640?wx_fmt=jpeg&wxfrom=5&wx_lazy=1" width="1009" onabort="" onblur="" onchange="" onclick="" ondblclick="" onerror="" onfocus="" onkeydown="" onkeypress="" onkeyup="" onmousedown="" onmousemove="" onmouseout="" onmouseover="" onmouseup="" onreset="" onresize="" onselect="" onsubmit="" onunload="" style="padding: 0px; margin: 0px; vertical-align: top; border: none; width: auto; height: auto;">
     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)
   jh@linux:~$ fortuneThere 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。
4. Cowsay这是一只可以说话的 ASCII Cow。

650. this.width=650;" src="http://mmbiz.qpic.cn/mmbiz/MOwlO0INfQrfZln4Pg14Y4FBfS9WNpSStQ7aic32NShR1SodNzSxeBQblhOSTZkfAkKNqkVPkRw8UuwJ52PcBEA/640?wx_fmt=jpeg&wxfrom=5&wx_lazy=1" class="content_image lazy" alt="640?wx_fmt=jpeg&wxfrom=5&wx_lazy=1" width="362" onabort="" onblur="" onchange="" onclick="" ondblclick="" onerror="" onfocus="" onkeydown="" onkeypress="" onkeyup="" onmousedown="" onmousemove="" onmouseout="" onmouseover="" onmouseup="" onreset="" onresize="" onselect="" onsubmit="" onunload="" style="padding: 0px; margin: 0px; vertical-align: top; border: none; width: auto; height: auto;">
     还可以把 cowsay 和 fortune 结合到一起使用:
651. this.width=650;" src="http://mmbiz.qpic.cn/mmbiz/MOwlO0INfQrfZln4Pg14Y4FBfS9WNpSSjNfdsEL2vxPz7vJ3NfcLn2Iib4DrRrp0Y5Gfk8LQtkbuGBPYKTwWBOg/640?wx_fmt=jpeg&wxfrom=5&wx_lazy=1" class="origin_image zh-lightbox-thumb lazy" alt="640?wx_fmt=jpeg&wxfrom=5&wx_lazy=1" width="561" onabort="" onblur="" onchange="" onclick="" ondblclick="" onerror="" onfocus="" onkeydown="" onkeypress="" onkeyup="" onmousedown="" onmousemove="" onmouseout="" onmouseover="" onmouseup="" onreset="" onresize="" onselect="" onsubmit="" onunload="" style="padding: 0px; margin: 0px; vertical-align: top; border: none; width: auto; height: auto;">
     jh@linux:~$ fortune -s | cowsay -f duck ___________________________________/ 《闺怨》 作者王昌龄 \ 闺中少妇不知愁春日凝妆上翠楼。 忽见陌头杨柳色悔教夫婿觅封侯。 / ----------------------------------- \ \ \ >()_ () _
     这只cow不仅会说话,还会思考,不信你看:
     jh@linux:~$ cowthink I am thinking! ________________( I am thinking! ) ---------------- o ^__ o (oo)_______ ()\ )/\ ||----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
     jh@linux:~$ cowsay -f ghostbusters Who you Gonna Call ____________________< Who you Gonna Call > -------------------- \ \ \ --- - /--______ --( / \ )XXXXXXXXXXX\v. .-XXX( O O )XXXXXXXXXXXXXXX- /XXX( U ) XXXXXXX\ /XXXXX( )-- XXXXXXXXXXX\ /XXXXX/ ( O ) XXXXXX \XXXXX\ XXXXX/ / XXXXXX _ \XXXXX XXXXXX/ XXXXXX _----> ---___ XXX__/ XXXXXX __ / - --__/ /\ XXXXXX / --/= -\ / XXXXXX '--- XXXXXX -/XXX\ XXXXXX /XXXXX \XXXXXXXXX \ /XXXXX/ \XXXXXX > /XXXXX/ \XXXXX--/ -- XXXX/ -XXXXXXXX--------------- XXXXXX- \XXXXXXXXXXXXXXXXXXXXXXXXXX/ ""VXXXXXXXXXXXXXXXXXXV""
     还可以这样玩,每次图形和文字都不一样:
     jh@linux:~$ cowsay -f "$(ls /usr/share/cowsay/cows | sort -R | head -1)" "$(fortune -s)" _______________________________________/ Q: What's the difference betweeen USL | and the Graf Zeppelin?
