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 Funny Commands

20 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


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.

3. Command: fortune

what about getting your random fortune, sometimes funny in terminal.

Install fortune

4. Command: rev (Reverse)

It reverse every string given to it, is not it funny.

7. Command: Cowsay

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

Install Cowsay

How about pipelineing ‘fortune command‘, described above with 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.
