[How to] Install new application through Terminal

So, you have installed a clean Ubuntu in your hard disk. The next thing you will do for sure is to get as many applications and software you need in this charming OS. For easy and simple solution to download and install new apps, just fire up your pre-installed Ubuntu Software Center and search for your desired application. Hit install and that's it. However, there's another way to get your applications which is by using Terminal. Terminal allow us to download and install (even multiple) known software fast and easy. In this post we will look into how to do this.

To install apps via Terminal, you need to have the application PPA in your repository while most of the daily apps we use should already have their PPA ready in the repository.

First, launch Terminal. Update the list of available software by typing:

sudo apt-get update

Then hit "Enter". It will ask for your password. Just type it and hit "Enter" again. (Note that the password you typed will not appear on the screen, not even in * form). Now it will update the software list to make sure you get the latest version of software later on.

After the list was updated, type:

 sudo apt-get install [name of the application(s)]

Example:

sudo apt-get install arista

Now this code will initiate the download and install process of an application named Arista which is a multimedia transcoder. You can install multiple application with one line of command at once by put a space between each app's name:

Example:

sudo apt-get install vlc firefox chromium-browser arista emesene

You might be asked to confirm the installation. Just type "Y" and hit "Enter":

Now wait the application(s) to be downloaded and installed. The time needed varies depends on the application and also internet speed. After the process finishes, you are now free to use the application you have just installed!
