This is the Just Share What I founded a post of Funny Linux 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
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
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:~# fortune You'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.

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

7. Command: Cowsay

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.
apt-get insatll xcowsay yum install xcowsay
Output
root@tecmint:~# xcowsay I Love nix
xcowsay command
apt-get insatll cowthink yum install cowthink
Output
root@tecmint:~# cowthink ....Linux is sooo funny
