Hardly a day goes by when I do not sit down at my computer and fire up the command line. Whether I am installing programs or managing users and permissions I find that I am much faster when using the command line. The command line is simply much more efficient than using the graphical user interface. The command line is also known as the terminal, shell, the console, command prompt, and command line interface ( CLI).
When working from the command line you may find that you are wanting to install a specific package for a certain task but do not know what that package is called. There is a way to search through the available packages or software from the repositories in the command line or terminal. This search tool is called apt-cache. This tutorial will show you the basic functions of the apt-cache command.

Debian’s Advanced Package Tool or APT for short is a system that helps with installation of software. APT was the first system to properly install software while adhering to any dependencies that are required. For example, when installing software in Linux you may find that that particular software you’re trying to install needs another program in order to run properly. You would then have to install that dependency before installing the software you actually wanted. When using APT you do not have to worry about dependencies because it is taken care of for you.
