10 Funny Commands of Linux or Linux is Fun in Terminal

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

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.

input
 root@tecmint:~# telnet towel.blinkenlights.nl



 

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)

6. 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.

root@tecmint:~# apt-get install oneko
root@tecmint:~# yum install oneko

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 xcowsay yum install xcowsay

Output

root@tecmint:~# xcowsay I Love nix

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 install cowthink yum install cowthink
