In Ubuntu one can add a repository via following command -
sudo add-apt-repository ppa:yannubuntu/boot-repair
As Ubuntu is based on Debian code base, I was expecting that the same would work in Debian too, but it doesn't.
Note: I know I can edit /etc/apt/sources.list, but I want to achieve this from the shell. I also want to know why the same command won't work when the code base is the same.
As pointed out by @voltagex in the comments, it can now be found in the software-properties-common package:
sudo apt-get install software-properties-common
The program add-apt-repository is available in Debian. It's in the python-software-properties package:
sudo apt-get install python-software-properties
It was added to that package in version 0.75. The current version in Debian Stable ('squeeze") is 0.60, so it doesn't have it. The version currently in Debian Testing ("wheezy") is 0.82.7.1debian1, so it's available there.

Assuming you're running a non-ancient version of Debian (Etch or later), you can just drop a file in /etc/apt/sources.list.d/ The file name must end with .list; Debian Stretch (not yet released) will likely add .sources with a different format.
The format is the same as the main sources.list file.
The advantage is, especially if this is for some software you're distributing, you don't have to worry merging your changes into a possibly-edited /etc/apt/sources.list file (especially hard to deal with if your program is uninstalled). You can use dpkg conffile support to put the file in /etc/apt/sources.list.d/.
apt-add-repository takes care of things like translating "ppa:" to an http://ppa.launchpad... type, and to download and install the repository key so that packages are not treated as suspicious

add-apt-repository can now be found in the software-properties-common package.
/etc/apt/sources.list, you might look at @Goez 's answer in this question.
Ubuntu is based on Debian but includes things Debian doesn't (and in turn are often incorporated into Debian later). The add-apt-repository command is an example which was included in Ubuntu first.
The add-apt-repository actually just executes a couple of commands to add the repository:
/etc/apt/sources.listA script that sort of does the same that can be found here is quoted below
#!/bin/bash
if [ $# -eq 1 ]
NM=$(uname -a && date)
NAME=$(echo $NM | md5sum | cut -f1 -d" ")
then
ppa_name=$(echo "$1" | cut -d":" -f2 -s)
if [ -z "$ppa_name" ]
then
echo "PPA name not found"
echo "Utility to add PPA repositories in your debian machine"
echo "$0 ppa:user/ppa-name"
else
echo "$ppa_name"
echo "deb http://ppa.launchpad.net/$ppa_name/ubuntu lucid main" >> /etc/apt/sources.list
apt-get update >> /dev/null 2> /tmp/${NAME}_apt_add_key.txt
key=$(cat /tmp/${NAME}_apt_add_key.txt | cut -d":" -f6 | cut -d" " -f3)
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys $key
rm -rf /tmp/${NAME}_apt_add_key.txt
fi
else
echo "Utility to add PPA repositories in your debian machine"
echo "$0 ppa:user/ppa-name"
fi
