These instructions will work for Ubuntu 12.04 and later.

Install term-animation

First, you need to install Perl module called term-animation. Open a command-line terminal by pressing CTRL+ALT+T.

First, type

sudo apt install libcurses-perl

This will install the program that will run perl scripts on your system.

Next, run

cd /tmp

to change your working directory to /tmp , this is the folder where temporary files are stored.

After you are in /tmp , you are going to have to download the source code for term-animation . To do this, type

wget http://search.cpan.org/CPAN/authors/id/K/KB/KBAUCOM/Term-Animation-2.6.tar.gz

Extract the tarball you just downloaded by running this command:

tar -zxvf Term-Animation-2.6.tar.gz

Change your working directory to the folder you just extracted (NOTE: if you ever forget where your working directory is, simply type pwd ).

cd Term-Animation-2.6

Next, you are going to run the perl script "Makefile.PL"

perl Makefile.PL && make && make test

(The && operator separates commands)

Finally, we can finish installing term-animation by running this command

sudo make install

Download and install Asciiquarium

Once again, we are going to change our working directory to /tmp .

cd /tmp

Now we are going to download the perl script that runs asciiquarium .

wget --no-check-certificate http://www.robobunny.com/projects/asciiquarium/asciiquarium.tar.gz

Extract the tarball you downloaded.

tar -zxvf asciiquarium.tar.gz

Now change the working directory to the folder you extracted.

cd asciiquarium_1.1

Next, we need to copy the perl script to /usr/local/bin where all of the executable commands are.

sudo cp asciiquarium /usr/local/bin/

Finally, to be allowed to run asciiquarium , you need to give yourself permission to execute the perl script.

sudo chmod 0755 /usr/local/bin/asciiquarium

Running asciiquarium

To watch asciiquarium in your terminal, simply type

asciiquarium

Simply press CTRL+C to stop the animation.
