Installing Software

Command Line

The most flexible method of installing and managing software is via the command line. The primary command we use for this is apt-get. The apt-get command automatically handles resolving dependencies, downloading, and installing (or removing) software packages.

apt-get commands are in the following form.

$ sudo apt-get <verb> <name>

Install a Package

$ sudo apt-get install <name>

For example,

$ sudo apt-get install csci1030u

Uninstall a Package

There are two methods of uninstalling a package. The first (remove) involves removing the package files, but leaves any configuration files installed. The second (purging) involves removing all of the package files, as well as any configuration files. When in doubt: remove, don't purge.

Remove

$ sudo apt-get remove <name>

For example, to remove csci1030u,

$ sudo apt-get remove csci1030u

Purge

$ sudo apt-get purge <name>

For example, to remove csci1030u and any configuration files,

$ sudo apt-get purge csci1030u

Note: The csci1030u package does not have any configuration files, so the two above commands are equivalent in this case. The difference becomes more apparent in packages such as vmware-view-client-config.
