add-apt-ppa 
Fetch the only corresponding apt package list immediately after added ppa repo.
Installation
Download the released tarball from releases page, extract the files, checkin the directory, and run make install as root. You can also clone the repo via git clone https://github.com/PeterDaveHello/ColorEchoForShell.git to get the files.
Usage
All the same as add-apt-repository/apt-add-repository(in package:software-properties-common)
The difference
Will do apt-get update for the ppa repository after added the repository. So that we don't need to do apt-get udpate, and can save time and resource because it will only update info about the just added ppa repository.
