Linux uses Apt-get to install software and uninstall software

1. Install the SOFTWARE:

sudo apt-get install ABC and sudo aptitude install ABC

Of course, the above ABC is only fictitious software. Sudo indicates that you are authorizing administrator (Superuser) permissions to the following command. This requires you to enter the administrator password. This is the same as when you open a new set of passwords, but now it's under the terminal. If you enter sudo directly Aptitude, you will see a newly-made package manager similar to the command-line version.

You can also use the command line search as you would search for software in a new building. The command is as follows:

Apt-cache Search ABC or aptitude search ABC

2. Uninstalling the Software

To remove a package command:

sudo apt-get remove ABC and sudo aptitude remove ABC

Delete the configuration file at the same time:

sudo apt-get remove–purge ABC and   sudo aptitude purge abc
