NAME

   apt-mark - show, set and unset various settings for a package

SYNOPSIS

   apt-mark {-f=filename | {auto | manual} pkg...  |
            {showauto | showmanual} [pkg...] } | {-v | --version} |
            {-h | --help}

   apt-mark {hold | unhold | install | remove | purge} pkg...  |
            {showhold | showinstall | showremove | showpurge} [pkg...]

DESCRIPTION

   apt-mark can be used as a unified front-end to set various settings for
   a package, such as marking a package as being automatically/manually
   installed or changing dpkg selections such as hold, install, deinstall
   and purge which are respected e.g. by apt-get dselect-upgrade or
   aptitude.

AUTOMATICALLY AND MANUALLY INSTALLED PACKAGES

   When you request that a package is installed, and as a result other
   packages are installed to satisfy its dependencies, the dependencies
   are marked as being automatically installed, while the package you
   installed explicitly is marked as manually installed. Once an
   automatically installed package is no longer depended on by any
   manually installed package it is considered no longer needed and e.g.
   apt-get or aptitude will at least suggest removing them.

   auto
       auto is used to mark a package as being automatically installed,
       which will cause the package to be removed when no more manually
       installed packages depend on this package.

   manual
       manual is used to mark a package as being manually installed, which
       will prevent the package from being automatically removed if no
       other packages depend on it.

   showauto
       showauto is used to print a list of automatically installed
       packages with each package on a new line. All automatically
       installed packages will be listed if no package is given. If
       packages are given only those which are automatically installed
       will be shown.

   showmanual
       showmanual can be used in the same way as showauto except that it
       will print a list of manually installed packages instead.

   Options
   -f=filename, --file=filename
       Read/Write package stats from the filename given with the parameter
       filename instead of from the default location, which is
       extended_status in the directory defined by the Configuration Item:
       Dir::State.

PREVENT CHANGES FOR A PACKAGE

   hold
       hold is used to mark a package as held back, which will prevent the
       package from being automatically installed, upgraded or removed.

   unhold
       unhold is used to cancel a previously set hold on a package to
       allow all actions again.

   showhold
       showhold is used to print a list of packages on hold in the same
       way as for the other show commands.

SCHEDULE PACKAGES FOR INSTALL, REMOVE AND PURGE

   Some front-ends like apt-get dselect-upgrade can be used to apply
   previously scheduled changes to the install state of packages. Such
   changes can be scheduled with the install, remove (also known as
   deinstall) and purge commands. Packages with a specific selection can
   be displayed with showinstall, showremove and showpurge respectively.
   More information about these so called dpkg selections can be found in
   dpkg(1).

OPTIONS

   -h, --help
       Show a short usage summary.

   -v, --version
       Show the program version.

   -c, --config-file
       Configuration File; Specify a configuration file to use. The
       program will read the default configuration file and then this
       configuration file. If configuration settings need to be set before
       the default configuration files are parsed specify a file with the
       APT_CONFIG environment variable. See apt.conf(5) for syntax
       information.

   -o, --option
       Set a Configuration Option; This will set an arbitrary
       configuration option. The syntax is -o Foo::Bar=bar.  -o and
       --option can be used multiple times to set different options.

FILES

   /var/lib/apt/extended_states
       Status list of auto-installed packages. Configuration Item:
       Dir::State::extended_states.
