apt-get

DESCRIPTION
       apt-get is the command-line tool for handling packages, and may be
       considered the user's "back-end" to other tools using the APT library.
       Several "front-end" interfaces exist, such as aptitude(8), synaptic(8)
       and wajig(1). [...]

 update
           update is used to resynchronize the package index files from their
           sources. The indexes of available packages are fetched from the
           location(s) specified in /etc/apt/sources.list. For example, when
           using a Debian archive, this command retrieves and scans the
           Packages.gz files, so that information about new and updated
           packages is available. An update should always be performed before
           an upgrade or dist-upgrade. Please be aware that the overall
           progress meter will be incorrect as the size of the package files
           cannot be known in advance.

upgrade
           upgrade is used to install the newest versions of all packages
           currently installed on the system from the sources enumerated in
           /etc/apt/sources.list. Packages currently installed with new
           versions available are retrieved and upgraded; under no
           circumstances are currently installed packages removed, or packages
           not already installed retrieved and installed. New versions of
           currently installed packages that cannot be upgraded without
           changing the install status of another package will be left at
           their current version. An update must be performed first so that
           apt-get knows that new versions of packages are available.
[...]
install
           install is followed by one or more packages desired for
           installation or upgrading. Each package is a package name, not a
           fully qualified filename (for instance, in a Debian system,
           apt-utils would be the argument provided, not
           apt-utils_1.2.10_amd64.deb). All packages required by the
           package(s) specified for installation will also be retrieved and
           installed. [...]
remove
           remove is identical to install except that packages are removed
           instead of installed. Note that removing a package leaves its
           configuration files on the system. [...]
purge
           purge is identical to remove except that packages are removed and
           purged (any configuration files are deleted too).
[...]
autoremove (and the auto-remove alias since 1.1)
           autoremove is used to remove packages that were automatically
           installed to satisfy dependencies for other packages and are now no
           longer needed
