There are pleny of console ASCII stuff out there that can make your console sysadmin boring life a little bit more funny and cherish some memories from the old times of 8 bit computers :).

One of this as I blogged earlier is cowsay and cowthink to generate a ascii picture with a cow with your custom message.
I've earlier blogged about that in my previous articleCreate ASCII Art Text bannners in Linux console / terminal with figlet and toilet

One of this cool things I'm using daily on my servers  is a cowsay console goodie together with a bash shell script that does visualize a random ASCII picture from a preset of pictures on each and every ssh login to my server.
The script I use is cowrand below is code:

#!/bin/bash
# cowsay pix randomizer by hip0
# it shows random ascii from the cowsay prog during logging. :]
a=0
b=1
cowrand='/etc/cowrand';
dir='/usr/share/cowsay/cows';
var=`ls -1 $dir | wc -l | awk '{ print $1}'`
#RANGE=$var
number=$RANDOM
let "number %= $var"
var1=`ls -1 $dir | head -n $number | tail -n 1 | head -n 1`
if [ -z “$var1” ]; then
$cowrand;
else
/usr/bin/cowsay -f $var1 Welc0m3 t0 pC-fREAK … Enj0y.
fi

 

The script is set as executable under /etc/cowrand

hipo@pcfreak:~$ ls -al /etc/cowrand
-rwxr-xr-x 1 hipo hipo 432 Nov 24 19:21 /etc/cowrand*

I've set this script to my /etc/profile to auto start on every login on my Debian Linux systems right after the comments like so:

hipo@pcfreak:~$ grep -i cowrand -A 2 -B 3 /etc/profile
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), …).
echo '';
/etc/cowrand | lolcat
echo '';
#/usr/bin/verse

As you can see to make my life even more funnier, I've installed another fun command lolcat

lolcat-screenshot

hipo@pcfreak:~$ apt-cache show lolcat |grep -i desc -A 3
Description-en: colorful `cat`
 lolcat concatenates files like the UNIX `cat` program, but colors it for the
 lulz in a rainbow animation. Terminals with 256 colors and animations are
 supported.

You can think of lolcat as a standard cat command that has been made to print in colors, this gives a funny results.

To add some spice to everything nice as a recipee for thethe creation of powerpuffgirls, I've come up with a way to use fortune
console tool that uses to print quotes out of a database to use as a source a big database containing the Holy Bible books of Old and New Testament Books. The fortune prints me out a quote extract from the bible on each and every remote SSH login to my machine. The content of this bible database for fortune bible_quotes_fortune.tar.gz can be downloaded and used from here.

The command used to print out a verse from the holy bible is:
 

 

hipo@pcfreak:~$ /usr/games/fortune -s /usr/local/fortune/
For if thou refuse to let them go, and wilt hold them still,
        — Exodus 9:2
hipo@pcfreak:~$ /usr/games/fortune -s /usr/local/fortune/
And when the queen of Sheba heard of the fame of Solomon concerning
the name of the LORD, she came to prove him with hard questions.
        — 1 Kings 10:1
hipo@pcfreak:~$ /usr/games/fortune -s /usr/local/fortune/
And Shelemiah, and Nathan, and Adaiah,
        — Ezra 10:39
hipo@pcfreak:~$ /usr/games/fortune -s /usr/local/fortune/
For by thee I have run through a troop: by my God have I leaped
over a wall.
        — 2 Samuel 22:30
hipo@pcfreak:~$ /usr/games/fortune -s /usr/local/fortune/
Unto the place of the altar, which he had make there at the first:
and there Abram called on the name of the LORD.
        — Genesis 13:4
hipo@pcfreak:~$ /usr/games/fortune -s /usr/local/fortune/
And there shall dwell in Judah itself, and in all the cities thereof
together, husbandmen, and they that go forth with flocks.
        — Jeremiah 31:24
hipo@pcfreak:~$ /usr/games/fortune -s /usr/local/fortune/
And he hath put a new song in my mouth, even praise unto our God:
many shall see it, and fear, and shall trust in the LORD.
        — Psalms 40:3
hipo@pcfreak:~$ /usr/games/fortune -s /usr/local/fortune/
And Jehoshaphat made peace with the king of Israel.
        — 1 Kings 22:44
 

 

The fortune is really awesome as it reminds me often of a verses from Holy Bible I often forget, the database is using the all famous King James Bible famous as (KJB) / (KJV) from 1611 this bible version that is like a protestant standard nowadays takes its name after James VI and I (James Charles Stuart; 19 June 1566 – 27 March 1625 – King of Scotland and Ireland) who was the sponsor of KJV collection and print.

Finally after adding the /usr/games/fortune -s /usr/local/fortune/ to the beginning of /etc/profile together with cowsay and cowrand I got this beautiful and educational result that combines fun with wisdom, below is example of what you will get after you  do a remote ssh login;

 

ssh your-machine.com

Those who have a Linux Graphical Environment desktop might also enjoy xcowsay

Another must I recommend to the text geeks is the caca-utils package which contains cool things such as aafire (cacafire)

cacaview-fire-screenshot-ascii-art

Or (Image to text converter) img2txt / cacaview (a text console picture viewer) that could give you a raw idea on how a png / jpg picture looks like (or at least the picture shapes) without a need for a GUI picture viewer such as Eye of the Gnome.

bear-for-you-picture-rose

Here is a original bear

cacaview-a-bear-for-you-picture-in-plain-text-ascii

And here is the one you'll see in cacaview 🙂
To read more about cacaview I have and its uses, check my previous article Viewing JPEG,GIF and PNG in ASCII with cacaview in Linux.
If you want to show off even more as a '1337 h4x0r' you might also show your sysadm 1337 5K!11Z to colleagues by showng them how you check weather via console (i've a separate article for how to ASCII art check colorful weather forecast via console / terminal ).

If you're too bored in your daily sys admin job, you might make some fun and take some useless effort to install ASCII Art Aquarium ASCIIQUARIUM

asciiquarium1

asciiquarium2

asciiquarium3

If you're crazy enough and want to torture your other sysadmin colleagues and a get a nice prank, you might install and set asciiquarium to auto run for their specific account on each and every login to some server until they control C or if you're a bit evil you can even set a small auto load on account login via ~/.bashrc shell script to 'Disable CTRL + C' combination 🙂
 

Of course there is plenty of other cool ASCII games and stuff. I've collected some of them by launching the Play Cool Ascii games service on my machine for ASCII art geeks to test out some ASCII games here.

Do you remember the bsdgames package which had the good old tetris-bsd – an ASCII tetris for terminal / console along with nethack, hunt and number of other cool ascii games? If you don't you can give a try to install the package if you don't have it yet, install it on Debian Linux / Ubuntu with.

linux:~# apt-get install –yes tetris-bsd

Then launch tetris-bsd like so:

$ /usr/games/tetris-bsd

But wait there is more just recently I found out there is a modern colorful version remake of bsd-tetris called bastet

To give it a try install it with apt-get on Deb based Linuces

linux:~$ /usr/games/bastet

FreeBSD users can also install it either via freebsd ports :

freebsd#  cd /usr/ports/games/bastet/ && make install clean

or through binary package with:


freebsd# pkg install bastet

Mac OS X users can also enjoy it but you need to install Mac OS X home brew package manager

Once having brew command install the tiny ASCII tetris game through Mac OS X terminal with:

$ brew install basket

Enjoy bastet 🙂
