How to manage packages using apt

apt is the Advanced Packaging Tool. It is a group of command-line programs that allow you to manage the set of installed packages on a system. The tool was created to run on Debian Linux releases. The primary command-line programs are apt-cache to find programs to download and install with the apt-get tool to do the actual downloading and installation. apt also manages the relationships between different packages, like if application A needs library B, apt will make sure B is installed first whenever you install A.

If you try to execute a command that isn't found on your system, you'll be told the apt-get command to download and install the package. For instance 'xjump' is a text adventure game most people won't have installed. If you try to run the program on a machine without the game, here is what you would see:

$ xjump

The program 'xjump' is currently not installed. You can install it by typing:

sudo apt-get install xjump

You would then run the "sudo apt-get install tome" specified, providing the password and pressing Y when asked to install.

$ sudo apt-get install xjump

If you're unclear what you want to install, just use the apt-cache command with the search option:

apt-cache search xjump
gnujump - platform game where you have to jump up to survive
gnujump-data - platform game where you have to jump up to survive - data files
xjump - jumping game for X

If you want to find out about a specific package to install, use the show option of apt-cache:

apt-cache show xjump
gnujump - platform game where you have to jump up to survive
gnujump-data - platform game where you have to jump up to survive - data files
xjump - jumping game for X
$ apt-cache show xjump

Description-en: jumping game for X
The epitome of addictive and pointless games, xjump is simply a game
where one jumps from one platform to a higher platform, over and over. If
you can't keep up with the pace of jumping, the floor swallows you up and
your game is over.
