SYNOPSIS

       cupt [ option... ] action [ { parameter | option } ... ]

ACTIONS

   Query actions
       version,-v,--version
	   prints versions of packages 'cupt' and 'libcupt-perl'

       help,-h,--help
	   prints the short help for available actions

       config-dump
	   prints all configuration variables to standard output

	   Example:

	   "cupt config-dump"

       show
	   prints version info of specified binary packages

	   This subcommand receives list of "Binary package version expression"'s, see below.

	   Specific options:

	   --all-versions,-a
	       print all versions of the package, not selected one

	       Corresponding configuration variable: apt::cache::allversions

	   --no-all-versions
	       don't print all versions of the package, use only selected one

	       Corresponding configuration variable: apt::cache::allversions

	   --with-release-info
	       also print information about release info where the version of the package live

	   Examples:

	   "cupt show qmmp"

	   "cupt show --all-versions qmmp debianutils"

	   "cupt show --with-release-info audacious/testing apt debianutils=2.3.38"

       showsrc
	   The same as show, only for source packages.

	   Examples:

	   "cupt showsrc --all-versions qmmp"

	   "cupt showsrc --with-release-info audacious/testing apt"

	   "cupt showsrc libxine1"

       search
	   searches for packages that contains some string within package names and package descriptions

	   This subcommand receives a list a Perl-compatible Regular Expressions (PCRE) to search. Only those packages will be printed that
	   contain all of specified patterns.

	   Specific options:

	   --case-sensitive
	       search case-sensitively

	   --names-only,-n
	       search only in package names

	       Corresponding configuration variable: apt::cache::namesonly

	   "cupt search nvidia driver"

	   "cupt search --case-sensitive Vim"

	   "cupt search -n vim"

	   "cupt search "package manager""

       showauto
	   prints list of automatically/manually installed packages, one package name per line

	   "cupt showauto": prints list of automatically installed packages

	   "cupt showauto --invert": prints list of manually installed packages

       depends
	   prints dependency relation expressions for given version of package

	   By default prints 'Pre-Depends', 'Depends' and 'Recommends' for the version.

	   This subcommand receives list of "Binary package version expression"'s, see below.

	   Specific options:

	   --with-suggests
	       take also 'Suggests' dependencies into account

	   --recurse
	       process the dependencies recursively

	       Corresponding configuration variable: apt::cache::recursedepends

	   --all-versions,-a
	       when --recurse is specified, pick up all versions for the relation expression, not the "best" one

	       Corresponding configuration variable: apt::cache::allversions

	   Examples:

	   "cupt depends nlkt perl/stable"

	   "cupt depends --important xserver-xorg-core"

	   "cupt depends --recurse xmlto"

       rdepends
	   same as depends, but prints reverse relations instead of forward ones

       why prints one of available dependency paths between package(s)/system and the package.

	   This subcommand receives a list of binary package expressions (which can be empty), then one binary package expression without
	   wildcards.

	   If the list of binary package expressions is empty (i.e. subcommand received only one argument), then the list is build of manually
	   installed packages in the system.

	   If no dependency paths found, prints nothing.

	   Uses configuration variables cupt::resolver::keep-recommends and cupt::resolver::keep-suggests to determine whether to honor Recommends
	   and Suggests respectively when building dependency paths.

	   Examples:

	   "cupt why kmail libgnutls26"

	   "cupt why libgnutls26"

	   "cupt why icedove kmail libgnutls26"

       policy
	   Given arguments, prints available versions with pins and release info for each binary package

	   Arguments: list of binary package names.

	   Given no arguments, prints available Release info for binary packages.

	   Specific options:

	   --show-dates
	       Show also publish and expiration dates for each record. Works only for a second form (i.e. no arguments).

	   Examples:

	   "cupt policy"

	   Examples:

	   "cupt policysrc"

	   "cupt policysrc --show-dates"

	   "cupt policysrc dpkg"

	   "cupt policysrc libpqxx libpqxx3"

       pkgnames
	   prints package names that start with a supplied suffix

	   If no suffix is given, prints all package names

	   Examples:

	   "cupt pkgnames"

	   "cupt pkgnames liba"

       changelog
	   displays changelog for given versions of packages

	   This subcommand receives list of "Binary package version expression"'s, see below.

	   actions

   Management actions
       update
	   updates package indexes

	   This subcommand receives no arguments.

	   Example:

	   "cupt update"

       install
	   installs, upgrades or downgrades specified packages

	   This subcommand receives list of "Binary package version expression"'s, see below.

	   If some version of package was already installed, this command will upgrade/downgrade it; otherwise, the package will be freshly
	   installed.

	   Examples:

	   "cupt install nlkt"

	   "cupt install devscripts xserver-xorg/experimental xfce4-mixer=4.6.0-2"

       remove
	   removes specified packages

	   This subcommand receives the list of package names.

	   Examples:

	   "cupt remove nlkt"

	   "cupt remove devscripts kde4-minimal"

       purge
	   removes specified packages along with their configuration files.  Also this command can purge the configuration files when the packages
	   are removed already.

	   This subcommand receives the list of package names.

	   Examples:

	   "cupt purge nlkt"

	   "cupt purge devscripts kde4-minimal"

	   See also the configuration option cupt::worker::purge.

       full-upgrade
	   performs as more upgrades of the installed packages as possible, the recommended way to do upgrades

	   This subcommand is usually invoked without any further parameters:

	   "cupt full-upgrade"

	   List of "Binary package version expression"'s can be however specified as additional parameters.

	   Example: the command "cupt full-upgrade xserver-xorg/installed" will try to upgrade your system, however preserving package
	   'xserver-xorg' to be sticked with currently installed version.

       safe-upgrade
	   the same as "full-upgrade", but with the change that problem resolver won't try to remove non-automatically installed packages in order
	   to upgrade more packages, equivalent of 'full-upgrade --no-remove'.

       dist-upgrade
	   the same as "full-upgrade", but firstly upgrades the package management tools, then upgrades the whole system.

	   Recommended over "full-upgrade" for major upgrades.

	   This subcommand cannot be run under the Cupt shell.

       reinstall
	   reinstalls specified binary packages

	   This subcommand receives list of binary package names.

	   Examples:

	   "cupt unmarkauto kpogre"

	   "cupt unmarkauto dpkg-dev"

       satisfy
	   performs all needed operations to satisfy list of specified relations

	   This subcommand receives the list of relations or relation lines. Relation and relation lines has the same syntax as defined in Debian
	   Policy S7.1.

	   The minus sign can be appended to some of relation expression lines to make relation expressions unsatisfied instead.

	   Examples:

	   "cupt satisfy "kmail (>= 4:4.2), wget (>= 1.10.0)""

	   "cupt satisfy "gettext (= 0.17-7)" "mail-transport-agent-""

       build-dep
	   performs all needed operations to satisfy list of build-dependencies of specified source packages

	   This subcommand receives the list of "Source package version expression"'s.

	   Examples:

	   Example: "cupt clean"

       autoclean
	   removes deb archives which are not available in package indexes and partially downloaded archive files from the cache on a disk

	   This subcommand receives no arguments.

	   Example: "cupt autoclean"

       snapshot save
	   saves a snapshot of the current packages state

	   This subcommand receives one argument - desired snapshot name.

	   Example: "cupt snapshot save old-udev"

	   On every shell prompt you can supply any valid subcommand from this manual page, using all allowed parameters, just if it was command
	   line. Simple shell quotes around arguments are also allowed.

	   You can use 'quit', 'exit', ':q' or 'q' command to exit cupt shell.

       management-specific options

       --no-remove
	   disallow problem resolver to remove manually installed packages. Packages that are marked to remove/purge in the command line will be
	   remove/purged as usual.

	   Corresponding configuration option: cupt::resolver::no-remove

       --no-auto-remove
	   don't try to remove automatically installed packages after doing requested actions

	   Corresponding configuration option: cupt::resolver::auto-remove

       --simulate,-s
	   don't modify anything in the system, just print supposed actions

	   Doesn't require root privileges.

	   Corresponding configuration option: cupt::worker::simulate

       --summary-only
	   Show only summary of actions without details.

	   Corresponding configuration options: cupt::console::actions-preview::show-summary, cupt::console::actions-preview::show-details.

       --no-summary
	   Show only details of actions without a summary.

	   Corresponding configuration options: cupt::console::actions-preview::show-summary, cupt::console::actions-preview::show-details.

       --resolver=
	   string, determines type of resolver: can be

	   fair
	       medium-class resolver. It chooses best possible solution (by overall score) each time. This is a default resolver.

	   full
	       full resolver. Guaranteed to suggest solution in precise order from the best to the worst result score (by the resolver's opinion).
	       Latter means that resolver builds full resolve tree before suggesting the solutions, which means large RAM and speed penalties. Use
	       it with caution.

	   Corresponding configuration option: cupt::resolver::type

       --max-solution-count=
	   number, determines how many maximum solutions will resolver store in memory. This option prevents large memory grows by purging away
	   solutions with worst scores.  Defaults to 512.  Note that very complex requests or requests on multi-repository system will increase
	   size of solution tree dramatically, so prepare to play with increasing this option accordingly.

	   Corresponding configuration option: cupt::resolver::max-solution-count

       --no-install-recommends,-R
	   cupt installs recommended packages by default, this option cancels described behavior

	   Corresponding configuration option: apt::install-recommends

       --show-archives,-A
	   when displaying actions preview prompt, display also release archives for each package

	   Corresponding configuration option: cupt::console::actions-preview::show-archives

       --show-codenames,-N
	   when displaying actions preview prompt, display also release codenames for each package

	   This option cannot be used together with --show-archives.

	   Corresponding configuration option: cupt::console::actions-preview::show-codenames

       --show-components,-C
	   when displaying actions preview prompt, display also release components for each package

	   Corresponding configuration option: cupt::console::actions-preview::show-components

       --show-versions,-V
	   when displaying actions preview prompt, display also versions of packages

	   Corresponding configuration option: cupt::console::actions-preview::show-versions

       --show-vendors,-O
	   when displaying actions preview prompt, display also vendors of packages

	   Corresponding configuration option: cupt::console::actions-preview::show-vendors

       --show-size-changes,-Z
	   when displaying actions preview prompt, display also changes in disk space usage for each package

	   Corresponding configuration option: cupt::console::actions-preview::show-size-changes

	   when displaying actions preview prompt, display also reasons why this action was considered to perform

	   Corresponding configuration option: cupt::resolver::track-reasons

       --show-not-preferred
	   when displaying actions preview prompt, display also packages which will have a not preferred version after the proposed changes

	   Corresponding configuration option: cupt::console::actions-preview::show-not-preferred

       --download-only,-d
	   stop after download stage, don't modify the system; not applicable for "markauto" and "unmarkauto" actions

	   Corresponding configuration option: cupt::worker::download-only

       --assume-yes,--yes,-y
	   don't ask for solution confirmation, assume the answer is 'y' ("yes"), except for dangerous actions, where assume 'q' ("decline and
	   exit")

	   Corresponding configuration options: apt::get::assume-yes, cupt::console::assume-yes

       management modifiers: action override options

       Unlike all the other options, these ones are positional and are effective only for the rest of parameters (and before next override option
       if any). One can specify as many action override options as needed.

       --install
	   install the rest of packages

	   Example:

	   "cupt remove msmtp-mta --install exim4-daemon-light esmtp" - install the packages 'exim4-daemon-light' and 'esmtp', remove the package
	   'msmtp-mta'

       --remove
	   remove rest of packages

	   Example:

	   "cupt install exim4-daemon-light --remove msmtp-mta esmtp" - install the package 'exim4-daemon-light', remove the packages 'msmtp-mta'
	   and 'esmtp'

       --purge
	   purge the rest of packages

	   Example:

	   "cupt purge libkate1 --remove libass4 --purge libdirac-decoder0" - remove the package 'libass4', purge packages 'libkate1' and
	   'libdirac-decoder0'

       --satisfy
	   satisfy the rest of relation expressions

	   Example:

	   "cupt install lightspark --remove gnash --satisfy "iceweasel (>= 5)"" - install the package 'lightspark', remove the packae 'gnash',
	   and make sure that iceweasel (at least of version 5) is installed

       --unsatisfy
	   unsatisfy the rest of relation expressions

	   Example:

	   "cupt install sieve-connect --unsatisfy "iceweasel (<< 3.5.20)"" - install the package 'sieve-connect', upgrade or remove the package
	   'iceweasel' if it is installed and has the version lower than '3.5.20'

       --iii
	   "install if installed" (see "iii" subcommand) the rest of packages

	   Example:

	   "cupt install libv4l-0 cupt --iii libreadline6 vlc*" - install packages 'libv4l-0' and 'cupt', install the preferred version of
	   'libreadline6' if it's installed already, install the preferred versions of packages which names start with 'vlc' and which are
	   installed already

       management modifiers: package name suffixes

       -   remove the package, can be used in non-remove actions

	   Examples:

	   "cupt install kde4 icewm-" - install the package 'kde4' and remove the package 'icewm' simultaneously.

	   "cupt full-upgrade iceweasel- icedove-" - upgrade the system, deleting iceweasel and icedove

       +   install the package, can be used in remove actions

	   Examples:

	   "cupt remove kde konqueror+" - remove kde, but install/upgrade konqueror

	   "cupt remove kde konqueror/installed+" - remove kde, but leave konqueror

EXPRESSIONS

       This section documents some common expressions used by actions.

   Binary package version expression
       package_name[modifier]

       selects one version of given binary package.

       Possible modifiers:

       <none>
	   selects policy version of the package

	   Example: "audacious".

       =<version string>
	   selects specified version of the package

	   Example: "audacious=1.5.1-2"

       /<distribution>
	   selects a version from specified distribution (archive name or codename)

	   Examples: "audacious/lenny" (by codename), "audacious/stable" (by archive name)

       /installed
	   selects installed version of the package

	   Example: "audacious/installed"

       Also, you may specify shell wildcars '*' and '?' in the package names.

       Examples: "xfce4-*", "python2.5-*/unstable", "?aff*/installed"

       For all management subcommands, there is also '@<path-to-file>' syntax. In this case this construction will be substituted by binary
       package expressions listed in the specified file one by line.

   Source package version expression
       package_name[modifier]

       selects one version of given source package.

       Possible modifiers are identical to those defined in "Binary package version expression", except for '/installed'.

       Also, you can specify "Binary package version expression" as "Source package version expression", then binary-to-source mapping will be
       performed.
