apt-mark


SYNOPSIS
       apt-mark [-hv] [-f=FILENAME]
                {auto | manual | showauto | showmanual} package...

DESCRIPTION
       apt-mark will change whether a package has been marked as being
       automatically installed.

       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. Once these automatically
       installed packages are no longer depended on by any manually installed
       packages, they will be removed by e.g.  apt-get or aptitude.

       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.

       hold
           hold is used to mark a package as hold back, which will prevent the
           package from being automatically installed, upgraded or removed.
           The command is only a wrapper around dpkg --set-selections and the
           state is therefore maintained by dpkg(1) and not effected by the
           --filename option.

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

       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.

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

OPTIONS
       -f=FILENAME, --file=FILENAME
           Read/Write package stats from FILENAME instead of the default
           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.
