how is the concatenate dog utility installed?

Question

Where is the repo to install dog?

To get the command on Ubuntu you can just open a terminal and type:

sudo apt-get install dog

After the installation you can retrieve all the information you need about dog...

I get:

thufir@doge:~$ 
thufir@doge:~$ sudo apt-get install dog
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package dog
thufir@doge:~$ 
thufir@doge:~$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04 LTS"
thufir@doge:~$ 

Just that it's the antagonist to cat makes it interesting.

My repos:

thufir@doge:~$ 
thufir@doge:~$ cat /etc/apt/sources.list

Answer 1

After searching for a while, I did find the launchpad page for dog: https://code.launchpad.net/ubuntu/+source/dog The problem is that it is only available for trusty (14.04) , precise (12.04), and vivid(15.04). So you will have to grab source code, and build it from that: http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/dog/trusty/files

Instructions on how to build it from source are in the README files supplied with the source code
