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

How about pipelineing ‘**fortune command**‘, described above with cowsay?
root@tecmint:~# fortune | 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.
**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 ####
root@tecmint:~# cowthink ....Linux is sooo funny

### 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 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
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.
**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.
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.
### 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.
root@tecmint:~# while true; do echo "$(date '+%D %T' | toilet -f term -F border --gay)"; sleep 1; done
**Note**: The above script when modified with following command, will gives similar output but with a little difference, check it in your terminal.
root@tecmint:~# while true; do clear; echo "$(date '+%D %T' | toilet -f term -F border --gay)"; sleep 1; done
### 14. Command: 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.
#### Install espeak ####
root@tecmint:~# apt-get install espeak
root@tecmint:~# yum install espeak
#### Output ####
root@tecmint:~# espeak "Tecmint is a very good website dedicated to Foss Community"
### 15. Command: 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.
Won’t it be an awesome feeling for you if you can update you **twitter status** from command line in front of your friend and they seems impressed. OK just replace **username, password** and **your status message** with your’s **username, password** and “**your status message**“.
### 18. 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.
First install “**apt-get install funny-manpages**” and then run man pages for the commands below. Some of them may be **18+**, run at your own risk, they all are too funny.

root@tecmint:~# man baby
### 20. Linux Tweaks ###
It is time for you to have some one liner **tweaks**.
root@tecmint:~# ^How did the sex change operation go?^
bash: :s^How did the sex change operation go?^ : substitution failed
root@tecmint:~# %blow
bash: fg: %blow: no such job
root@tecmint:~# make love
make: *** No rule to make target `love'. Stop.
$ [ whereis my brain?
sh: 2: [: missing ]
% man: why did you get a divorce?
man:: Too many arguments.
% !:say, what is saccharine?
Bad substitute.
server@localhost:/srv$ \(-
bash: (-: command not found
Linux is sexy: **who | grep -i blonde | date; cd ~; unzip; touch; strip; finger; mount; gasp; yes; uptime; umount; sleep** (If you know what i mean)
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.
