We have covered Adding PPAs in Ubuntu ,But that method seems to be consuming a lot of time.

We know that CLI can really save our precious time, so here's the simple tutorial explaining how-to add PPA from Terminal.

Suppose, I wanna download HandBrake: Open Source Video TranscoderApplication from Official PPA of Handbrake.
PPAs are usually found in : Personal Package Archives : Ubuntu

Go to Launchpad website & search for the Application you need to download, In this tutorial we will be adding Handbrake Official PPA.

Now, Open the Terminal & Type :

 sudo add-apt-repository APT-Line 

What is APT-Line ? Check out the image below :


So,
To Add "Handbrake" Official PPA, I have to type in Terminal as :

 sudo add-apt-repository ppa:stebbins/handbrake-releases 

& Press Enter.
Again two options in Terminal will pop, something like :
- Press "Enter" to ADD PPA ( or continue)
- Press "Ctrl+c" to leave.

Press "Enter" & the keyrings & repository.list will be downloaded to your computer.

Now, In Terminal Type :

 sudo apt-get update 

to update the repository.

And then, you can use :

 sudo apt-get install APP_NAME 

to Download the Application/File you want to install from modified repository.

Here as we are using PPA for handbrake, we'll download Handbrake by:

 sudo apt-get install handbrake-gtk 

👍
