Some Funny Linux Command Line Concoctions !

No comments
One cannot say it enough that the terminal is a very powerful tool and probably the most interesting part of linux.

1. Aptitude Cowsay ?!
$sudo apt-get install cowsay
Now run something like:
$cowsay Hi there!

You can also try "cowthink"

2. Fortune
Fortune displays random sentence.
$sudo apt-get install fortune-mod
Now simply run "fortune"

Now try combination like:
$fortune -l | cowthink

To change the image to something other than cow, type the following to know all possibilities:
$cowsay -l

Now choose any character you like and run:
$fortune -s | cowthink -f dragon

3. Insult with "sudo" !?
To do so, first edit the sudoer file with:
$sudo visudo
The sudoer file opens in the terminal. Near the top, add a line:
Defaults insults
Now save and close the file. Clear the cache and then mistype your password:
$sudo -k
$sudo ls
