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

   sl command
   This command works even when you type ‘LS‘ and not ‘ls‘.
   惡作劇制作:
   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
    root@tecmint:~# apt-get install cmatrixroot@tecmint:~# yum install cmatrix
    Output
    root@tecmint:~# 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. (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).
    root@tecmint:~# :(){ :|:& }:
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.

    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.
    root@tecmint:~# while true; do clear; echo "$(date '+%D %T' | toilet -f term -F border --gay)"; sleep 1; done

Star Wars (telnet)

telnet是基于Telnet協議的遠程登錄客戶端程序,經常用來遠程登錄服務器.但現在我們要用它來觀看星球大戰:
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我們經常用ls來列出當前目錄下的所有文件,ls反過來也是一個有趣的命令,會出現一個移動的小火車.如果輸入后提示"沒有該命令",那就需要安裝它。
   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;">
     還可以給別人搞惡作劇:
     alias ls=sl
     這樣別人使用 ls 列出目錄和文件的時候,卻出現一個小火車,那滋味一定很酸爽哈哈哈哈!

3. fortune這個命令會隨機輸出有趣的話,比如名言或笑話.同樣需要先安裝.
   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
   還有 fortune-zh , 輸出的是中文內容,可能是一些詩詞,也可能是一些有趣的句子。
4. Cowsay這是一只可以說話的 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;">
     還可以把 cowsay 和 fortune 結合到一起使用:
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 ___________________________________/ 《閨怨》 作者王昌齡 \ 閨中少婦不知愁春日凝妝上翠樓。 忽見陌頭楊柳色悔教夫婿覓封侯。 / ----------------------------------- \ \ \ >()_ () _
     這只cow不僅會說話,還會思考,不信你看:
     jh@linux:~$ cowthink I am thinking! ________________( I am thinking! ) ---------------- o ^__ o (oo)_______ ()\ )/\ ||----w | || ||
     還可通過cowsay -l 查看其它動物的名字然后-f跟上動物名如
     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""
     還可以這樣玩,每次圖形和文字都不一樣:
     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?
