       aptitude help

説明
       aptitude は Debian GNU/Linux のパッケージシステムに対するテキストベースのインタフェースです。

       ユーザはパッケージの一覧を表示したり、パッケージのインストール・更新・削除などといったパッケージ管理作業を行ったりできます。アクションはビジュ
       アルインタフェースとコマンドラインから行えます。

COMMAND-LINE ACTIONS
       ハイフン (「-」) から始まらない最初の引数は、プログラムが行うアクションだと見なされます。アクションがコマンドラインで与えられない場
       合、aptitude はビジュアルモードで起動します。

       以下のアクションが利用可能です。

       install
           Install one or more packages. The packages should be listed after
           the 「install」 command; if a package name contains a tilde character
           (「~」) or a question mark (「?」), it will be treated as a search
           pattern and every package matching the pattern will be installed
           (see the section 「Search Patterns」 in the aptitude reference
           manual).

           To select a particular version of the package, append 「=<version>」
           to the package name: for instance, 「aptitude install apt=0.3.1」.
           Similarly, to select a package from a particular archive, append
           「/<archive>」 to the package name: for instance, 「aptitude install
           apt/experimental」. You cannot specify both an archive and a version
           for a package.

           必ずしも、コマンドラインに連ねられたパッケージすべてがインストール対象でなければいけないわけではありません。パッケージ名に「上書き指定
           子」を付記すると、そのパッケージに対して aptitude に別のことをさせることが可能です。例えば、aptitude remove
           wesnoth+ とすると、wesnoth を削除ではなくインストールできます。以下の上書き指定子が利用可能です。

           <パッケージ>+
               <パッケージ> をインストールします。

               If the package was not installed, it is marked as manually
               installed, and the dependencies newly installed are marked with
               the automatic flag. If the package or the dependencies were
               already installed, the automatic flag is preserved. See the
               section about automatic installations in the documentation for
               more information.

           <パッケージ>+M
               <パッケージ> をインストールし、その後すぐに、自動的にインストールされたという印をそれに添付します (<パッケージ> に依存
               するものがなくなった場合、そのパッケージはすぐに削除されてしまうことに注意してください)。

           <パッケージ>-
               <パッケージ> を削除します。

           <パッケージ>_
               <パッケージ> を完全削除します。すなわち、パッケージ自体とそれに関連する設定ファイルやデータファイルを削除します。

           <パッケージ>=
               <パッケージ> を固定します。すなわち、今後どのようなインストール・更新・削除を行っても、このパッケージは自動的には更新されま
               せん。

           <パッケージ>:
               <パッケージ> を現在のバージョンに一時的に固定します。つまり、インストール・削除・更新をすべて取り消します。「hold」
               (前述) とは異なり、このコマンドを用いても将来パッケージが自動的に更新されなくなることはありません。

           <パッケージ>&M
               自動的にインストールされたという印を <パッケージ> に添付します。

           <パッケージ>&m
               手動でインストールされたという印を <パッケージ> に添付します。

           <package>&BD
               Install the build-dependencies of a <package>.

           特別な場合として、引数を与えずに「install」を実行すると、保存されているアクションや実行されていないアクションが実行されます。

               注記
               Once you enter Y at the final confirmation prompt, the
               「install」 command will modify aptitude's stored information
               about what actions to perform. Therefore, if you issue (e.g.)
               the command 「aptitude install foo bar」 on packages previously
               uninstalled, and then the installation fails once aptitude has
               started downloading and installing packages, you will need to
               run 「aptitude remove foo bar」 to go back to the previous state
               (and possibly undo installations or upgrades to other packages
               that were affected by the 「install」 action).

       remove, purge, reinstall
           These commands are the same as 「install」, but apply the named
           action to all packages given on the command line for which it is
           not overridden.

           例えば、「aptitude remove '~ndeity'」とすると、「deity」を名前に含むパッケージがすべて削除されます。

       build-depends, build-dep
           Satisfy the build-dependencies of a package. Each package name may
           be a source package, in which case the build dependencies of that
           source package are installed; otherwise, binary packages are found
           in the same way as for the 「install」 command, and the
           build-dependencies of the source packages that build those binary
           packages are satisfied.

           If the command-line parameter --arch-only is present, only
           architecture-dependent build dependencies (i.e., not
           Build-Depends-Indep or Build-Conflicts-Indep) will be obeyed.

       markauto, unmarkauto
           それぞれ、自動的にインストールされた、および手動でインストールされたという印をパッケージに添付します。パッケージの指定は
           「install」コマンドとまったく同じ方法で行います。例えば「aptitude markauto '~slibs'」を実行する
           と、「libs」セクションのパッケージすべてに、自動的にインストールされたという印が添付されます。

           自動的にインストールしたパッケージについてのさらに詳しい情報は、aptitude リファレンスマニュアルの「自動的にインストールした
           パッケージの管理」セクションを参照してください。

       hold, unhold, keep
           Mark packages to be on hold, remove this property, or set to keep
           in the current state. Packages are specified in exactly the same
           way as for the 「install」 command. For instance, 「aptitude hold
           '~e^dpkg$'」 will mark all packages coming from the source package
           「dpkg」 to be on hold.

           The difference between hold and keep is that hold will cause a
           package to be ignored by future safe-upgrade or full-upgrade
           commands, while keep merely cancels any scheduled actions on the
           package.  unhold will allow a package to be upgraded by future
           safe-upgrade or full-upgrade commands, without otherwise altering
           its state.

       keep-all
           設定されていたアクションをすべてのパッケージについて取り消します。つまり、インストール・削除・更新といった面倒な状態をもったあらゆる
           パッケージから、そういった状態を取り除きます。

       forget-new
           どのパッケージが「新規」かについての内部情報を消去します (ビジュアルモードで「f」を押すのと等価です)。

           This command accepts package names or patterns as arguments. If the
           string contains a tilde character (「~」) or a question mark (「?」),
           it will be treated as a search pattern and every package matching
           the pattern will be considered (see the section 「Search Patterns」
           in the aptitude reference manual).

       forbid-version
           Forbid a package from being upgraded to a particular version, while
           allowing automatic upgrades to future versions. This is useful for
           example to avoid a known broken version of a package, without
           having to set and clear manual holds.

           By default, aptitude will select the forbidden version to be the
           one which the package would normally be upgraded (the candidate
           version). This may be overridden by appending 「=<version>」 to the
           package name: for instance, 「aptitude forbid-version
           vim=1.2.3.broken-4」.

           To revert the action, 「aptitude install <package>」 will remove the
           ban. To remove the forbidden version without installing the
           candidate version, the current version should be appended: 「install
           <package>=<version>」.

       update
           apt 入手先から入手可能なパッケージの一覧を更新します (これは、「apt-get update」と等価です)。

       safe-upgrade
           Upgrades installed packages to their most recent version. Installed
           packages will not be removed unless they are unused (see the
           section 「Managing Automatically Installed Packages」 in the aptitude
           reference manual). Packages which are not currently installed may
           be installed to resolve dependencies unless the --no-new-installs
           command-line option is supplied.

           If no <package>s are listed on the command line, aptitude will
           attempt to upgrade every package that can be upgraded. Otherwise,
           aptitude will attempt to upgrade only the packages which it is
           instructed to upgrade. The <package>s can be extended with suffixes
           in the same manner as arguments to aptitude install, so you can
           also give additional instructions to aptitude here; for instance,
           aptitude safe-upgrade bash dash- will attempt to upgrade the bash
           package and remove the dash package.

           It is sometimes necessary to remove one package in order to upgrade
           another; this command is not able to upgrade packages in such
           situations. Use the full-upgrade command to upgrade as many
           packages as possible.

       full-upgrade
           Upgrades installed packages to their most recent version, removing
           or installing packages as necessary. It also installs new Essential
           or Required packages. This command is less conservative than
           safe-upgrade and thus more likely to perform unwanted actions.
           However, it is capable of upgrading packages that safe-upgrade
           cannot upgrade.

           If no <package>s are listed on the command line, aptitude will
           attempt to upgrade every package that can be upgraded. Otherwise,
           aptitude will attempt to upgrade only the packages which it is
           instructed to upgrade. The <package>s can be extended with suffixes
           in the same manner as arguments to aptitude install, so you can
           also give additional instructions to aptitude here; for instance,
           aptitude full-upgrade bash dash- will attempt to upgrade the bash
           package and remove the dash package.

               注記
               This command was originally named dist-upgrade for historical
               reasons, and aptitude still recognizes dist-upgrade as a
               synonym for full-upgrade.

       search
           Searches for packages matching one of the patterns supplied on the
           command line. All packages which match any of the given patterns
           will be displayed; for instance, 「aptitude search '~N' edit」 will
           list all 「new」 packages and all packages whose name contains
           「edit」. For more information on search patterns, see the section
           「Search Patterns」 in the aptitude reference manual.

               注記
               In the example above, 「aptitude search '~N' edit」 has two
               arguments after search and thus is searching for two patterns:
               「~N」 and 「edit」. As described in the search pattern reference,
               a single pattern composed of two sub-patterns separated by a
               space (such as 「~N edit」) matches only if both patterns match.
               Thus, the command 「aptitude search '~N edit'」 will only show
               「new」 packages whose name contains 「edit」.
           -F オプションを与えない場合、aptitude search の出力はこのようになります。

               i   apt                             - Advanced front-end for dpkg
               pi  apt-build                       - frontend to apt to build, optimize and in
               cp  apt-file                        - APT package searching utility -- command-
               ihA raptor-utils                    - Raptor RDF Parser utilities

           検索結果はそれぞれ異なる行に一覧表示されます。各行の第 1 文字はパッケージの現在の状態を示します。最もありふれた状態は、システムに
           パッケージが存在した形跡がないという意味の p、パッケージが削除されたがシステムに設定ファイルが残っているという意味の c、パッケージ
           がインストールされているという意味の i、パッケージが仮想パッケージであるという意味の v です。第 2 文字は、パッケージに対して行
           うよう保存されたアクションを示します (アクションが存在する場合で、なければ空欄が表示されます)。最もありふれた状態は、パッケージがイ
           ンストール予定であるという意味の i、パッケージが削除予定であるという意味の d、パッケージおよびその設定ファイルが削除予定であるとい
           う意味の p です。第 3 文字が A である場合、そのパッケージは自動的にインストールされたものです。

           For a complete list of the possible state and action flags, see the
           section 「Accessing Package Information」 in the aptitude reference
           guide. To customize the output of search, see the command-line
           options -F and --sort.

       show
           Displays detailed information about one or more packages. If a
           package name contains a tilde character (「~」) or a question mark
           (「?」), it will be treated as a search pattern and all matching
           packages will be displayed (see the section 「Search Patterns」 in
           the aptitude reference manual).

           饒舌レベルが 1 以上の場合 (つまり、コマンドラインに -v が 1 つ以上与えられている場合)、そのパッケージのすべてのバージョン
           について情報が表示されます。それ以外の場合は「バージョン候補」(「aptitude install」がダウンロードするバージョン) に
           関する情報が表示されます。

           You can display information about a different version of the
           package by appending =<version> to the package name; you can
           display the version from a particular archive or release by
           appending /<archive> or /<release> to the package name: for
           instance, /unstable or /sid. If either of these is present, then
           only the version you request will be displayed, regardless of the
           verbosity level.

           饒舌レベルが 1 以上の場合、パッケージのアーキテクチャ・圧縮サイズ・ファイル名・md5sum の各フィールドが表示されます。饒舌レベ
           ルが 2 以上の場合、各アーカイブについて、そのアーカイブがもつ 1 つ以上の選択バージョンが一度ずつ表示されます。

       showsrc
           Displays detailed information about one or more source packages.

           This is a thin wrapper over apt(8).

       source
           Downloads one or more source packages.

           This is a thin wrapper over apt(8).

       versions
           Displays the versions of the packages listed on the command-line.

               $ aptitude versions wesnoth
               p   1:1.4.5-1                                                             100
               p   1:1.6.5-1                                    unstable                 500
               p   1:1.7.14-1                                   experimental             1

           Each version is listed on a separate line. The leftmost three
           characters indicate the current state, planned state (if any), and
           whether the package was automatically installed; for more
           information on their meanings, see the documentation of aptitude
           search. To the right of the version number you can find the
           releases from which the version is available, and the pin priority
           of the version.

           If a package name contains a tilde character (「~」) or a question
           mark (「?」), it will be treated as a search pattern and all matching
           versions will be displayed (see the section 「Search Patterns」 in
           the aptitude reference manual). This means that, for instance,
           aptitude versions '~i' will display all the versions that are
           currently installed on the system and nothing else, not even other
           versions of the same packages.

               $ aptitude versions '~nexim4-daemon-light'
               Package exim4-daemon-light:
               i   4.71-3                                                                100
               p   4.71-4                                       unstable                 500

               Package exim4-daemon-light-dbg:
               p   4.71-4                                       unstable                 500

           If the input is a search pattern, or if more than one package's
           versions are to be displayed, aptitude will automatically group the
           output by package, as shown above. You can disable this via
           --group-by=none, in which case aptitude will display a single list
           of all the versions that were found and automatically include the
           package name in each output line:

               $ aptitude versions --group-by=none '~nexim4-daemon-light'
               i   exim4-daemon-light 4.71-3                                             100
               p   exim4-daemon-light 4.71-4                    unstable                 500
               p   exim4-daemon-light-dbg 4.71-4                unstable                 500

           To disable the package name, pass --show-package-names=never:

               $ aptitude versions --show-package-names=never --group-by=none '~nexim4-daemon-light'
               i   4.71-3                                                                100
               p   4.71-4                                       unstable                 500
               p   4.71-4                                       unstable                 500

           In addition to the above options, the information printed for each
           version can be controlled by the command-line option -F. The order
           in which versions are displayed can be controlled by the
           command-line option --sort. To prevent aptitude from formatting the
           output into columns, use --disable-columns.

       add-user-tag, remove-user-tag
           Adds a user tag to or removes a user tag from the selected group of
           packages. If a package name contains a tilde (「~」) or question mark
           (「?」), it is treated as a search pattern and the tag is added to or
           removed from all the packages that match the pattern (see the
           section 「Search Patterns」 in the aptitude reference manual).

           User tags are arbitrary strings associated with a package. They can
           be used with the ?user-tag(<tag>) search term, which will select
           all the packages that have a user tag matching <tag>.

       why, why-not
           Explains the reason that a particular package should or cannot be
           installed on the system.

           This command searches for packages that require or conflict with
           the given package. It displays a sequence of dependencies leading
           to the target package, along with a note indicating the installed
           state of each package in the dependency chain:

               $ aptitude why kdepim
               i   nautilus-data Recommends nautilus
               i A nautilus      Recommends desktop-base (>= 0.2)
               i A desktop-base  Suggests   gnome | kde | xfce4 | wmaker
               p   kde           Depends    kdepim (>= 4:3.4.3)

           The command why finds a dependency chain that installs the package
           named on the command line, as above. Note that the dependency that
           aptitude produced in this case is only a suggestion. This is
           because no package currently installed on this computer depends on
           or recommends the kdepim package; if a stronger dependency were
           available, aptitude would have displayed it.

           In contrast, why-not finds a dependency chain leading to a conflict
           with the target package:

               $ aptitude why-not textopo
               i   ocaml-core          Depends   ocamlweb
               i A ocamlweb            Depends   tetex-extra | texlive-latex-extra
               i A texlive-latex-extra Conflicts textopo

           If one or more <pattern>s are present (in addition to the mandatory
           last argument, which should be a valid <package> name), then
           aptitude will begin its search at these patterns. That is, the
           first package in the chain it prints to explain why <package> is or
           is not installed, will be a package matching the pattern in
           question. The patterns are considered to be package names unless
           they contain a tilde character (「~」) or a question mark (「?」), in
           which case they are treated as search patterns (see the section
           「Search Patterns」 in the aptitude reference manual).

           If no patterns are present, then aptitude will search for
           dependency chains beginning at manually installed packages. This
           effectively shows the packages that have caused or would cause a
           given package to be installed.

               注記
               aptitude why does not perform full dependency resolution; it
               only displays direct relationships between packages. For
               instance, if A requires B, C requires D, and B and C conflict,
               「aptitude why-not D」 will not produce the answer 「A depends on
               B, B conflicts with C, and D depends on C」.
           By default aptitude outputs only the 「most installed, strongest,
           tightest, shortest」 dependency chain. That is, it looks for a chain
           that only contains packages which are installed or will be
           installed; it looks for the strongest possible dependencies under
           that restriction; it looks for chains that avoid ORed dependencies
           and Provides; and it looks for the shortest dependency chain
           meeting those criteria. These rules are progressively weakened
           until a match is found.

           If the verbosity level is 1 or more, then all the explanations
           aptitude can find will be displayed, in inverse order of relevance.
           If the verbosity level is 2 or more, a truly excessive amount of
           debugging information will be printed to standard output.

           This command returns 0 if successful, 1 if no explanation could be
           constructed, and -1 if an error occurred.

       clean
           以前ダウンロードした .deb ファイルをパッケージキャッシュディレクトリ (通常 /var/cache/apt/archives)

       changelog
           指定されたソースパッケージまたはバイナリパッケージの各々について、Debian パッケージ更新履歴をダウンロードして表示します。

           By default, the changelog for the version which would be installed
           with 「aptitude install」 is downloaded. You can select a particular
           version of a package by appending =<version> to the package name;
           you can select the version from a particular archive or release by
           appending /<archive> or /<release> to the package name (for
           instance, /unstable or /sid).

       download
           指定されたパッケージの .deb ファイルをカレントディレクトリにダウンロードします。

           This is a thin wrapper over apt(8).

       extract-cache-subset
           Copy the apt configuration directory (/etc/apt) and a subset of the
           package database to the specified directory. If no packages are
           listed, the entire package database is copied; otherwise only the
           entries corresponding to the named packages are copied. Each
           package name may be a search pattern, and all the packages matching
           that pattern will be selected (see the section 「Search Patterns」 in
           the aptitude reference manual). Any existing package database files
           in the output directory will be overwritten.

           Dependencies in binary package stanzas will be rewritten to remove
           references to packages not in the selected set.

       help
           利用可能なコマンドとオプションを簡潔にまとめて表示します。

オプション
       以上のアクションの振る舞いを変更するのに、以下のオプションが利用可能です。どのオプションも全てのコマンドに使えますが、オプションによっては特定
       のコマンドに適用できず無視されます。

       --add-user-tag <tag>
           For full-upgrade, safe-upgrade, forbid-version, hold, install,
           keep-all, markauto, unmarkauto, purge, reinstall, remove, unhold,
           and unmarkauto: add the user tag <tag> to all packages that are
           installed, removed, or upgraded by this command as if with the
           add-user-tag command.

       --add-user-tag-to <tag>,<pattern>
           For full-upgrade, safe-upgrade, forbid-version, hold, install,
           keep-all, markauto, unmarkauto, purge, reinstall, remove, unhold,
           and unmarkauto: add the user tag <tag> to all packages that match
           <pattern> as if with the add-user-tag command. The pattern is a
           search pattern as described in the section 「Search Patterns」 in the
           aptitude reference manual.

           For instance, aptitude safe-upgrade --add-user-tag-to
           "new-installs,?action(install)" will add the tag new-installs to
           all the packages installed by the safe-upgrade command.

       --allow-new-upgrades
           When the safe resolver is being used (i.e., --safe-resolver was
           passed, the action is safe-upgrade, or
           Aptitude::Always-Use-Safe-Resolver is set to true), allow the
           dependency resolver to install upgrades for packages regardless of
           the value of Aptitude::Safe-Resolver::No-New-Upgrades.

       --allow-new-installs
           Allow the safe-upgrade command to install new packages; when the
           safe resolver is being used (i.e., --safe-resolver was passed, the
           action is safe-upgrade, or Aptitude::Always-Use-Safe-Resolver is
           set to true), allow the dependency resolver to install new
           packages. This option takes effect regardless of the value of
           Aptitude::Safe-Resolver::No-New-Installs.

       --allow-untrusted
           Install packages from untrusted sources without prompting. You
           should only use this if you know what you are doing, as it could
           easily compromise your system's security.

       --disable-columns
           This option causes aptitude search and aptitude versions to output
           their results without any special formatting. In particular:
           normally aptitude will add whitespace or truncate search results in
           an attempt to fit its results into vertical 「columns」. With this
           flag, each line will be formed by replacing any format escapes in
           the format string with the corresponding text; column widths will
           be ignored.

           For instance, the first few lines of output from 「aptitude search
           -F '%p %V' --disable-columns libedataserver」 might be:

               disksearch 1.2.1-3
               hp-search-mac 0.1.3
               libbsearch-ruby 1.5-5
               libbsearch-ruby1.8 1.5-5
               libclass-dbi-abstractsearch-perl 0.07-2
               libdbix-fulltextsearch-perl 0.73-10

           As in the above example, --disable-columns is often useful in
           combination with a custom display format set using the command-line
           option -F.

           This corresponds to the configuration option
           Aptitude::CmdLine::Disable-Columns.

       -D, --show-deps
           For commands that will install or remove packages (install,
           full-upgrade, etc), show brief explanations of automatic
           installations and removals.

           これは設定オプション Aptitude::CmdLine::Show-Deps に相当します。

       -d, --download-only
           必要に応じてパッケージをパッケージキャッシュにダウンロードしますが、インストールや削除はしません。デフォルトでは、パッケージキャッシュ
           は /var/cache/apt/archives に保存されます。

           これは設定オプション Aptitude::CmdLine::Download-Only に相当します。

       -F <フォーマット>, --display-format <フォーマット>
           Specify the format which should be used to display output from the
           search and versions commands. For instance, passing 「%p %v %V」 for
           <format> will display a package's name, followed by its currently
           installed version and its candidate version (see the section
           「Customizing how packages are displayed」 in the aptitude reference
           manual for more information).

           The command-line option --disable-columns is often useful in
           combination with -F.

           For search, this corresponds to the configuration option
           Aptitude::CmdLine::Package-Display-Format; for versions, this
           corresponds to the configuration option
           Aptitude::CmdLine::Version-Display-Format.

       -f
           コマンドラインで要求されたアクションを無視することになってもなお、破損パッケージの依存関係を修正しようとします。

           これは設定項目 Aptitude::CmdLine::Fix-Broken に相当します。

       --full-resolver
           When package dependency problems are encountered, use the default
           「full」 resolver to solve them. Unlike the 「safe」 resolver activated
           by --safe-resolver, the full resolver will happily remove packages
           to fulfill dependencies. It can resolve more situations than the
           safe algorithm, but its solutions are more likely to be
           undesirable.

           This option can be used to force the use of the full resolver even
           when Aptitude::Always-Use-Safe-Resolver is true.

       --group-by <grouping-mode>
           Control how the versions command groups its output. The following
           values are recognized:

           •   archive to group packages by the archive they occur in
               (「stable」, 「unstable」, etc). If a package occurs in several
               archives, it will be displayed in each of them.

           •   auto to group versions by their package unless there is exactly
               one argument and it is not a search pattern.

           •   none to display all the versions in a single list without any
               grouping.

           •   package to group versions by their package.

           •   source-package to group versions by their source package.

           •   source-version to group versions by their source package and
               source version.

           This corresponds to the configuration option
           Aptitude::CmdLine::Versions-Group-By.

       -h, --help
           簡潔なヘルプメッセージを表示します。help アクションと同一です。

       --log-file=<file>
           If <file> is a nonempty string, log messages will be written to it,
           except that if <file> is 「-」, the messages will be written to
           standard output instead. If this option appears multiple times, the
           last occurrence is the one that will take effect.

           This does not affect the log of installations that aptitude has
           performed (/var/log/aptitude); the log messages written using this
           configuration include internal program events, errors, and
           debugging messages. See the command-line option --log-level to get
           more control over what gets logged.

           This corresponds to the configuration option
           Aptitude::Logging::File.

       --log-level=<level>, --log-level=<category>:<level>
           --log-level=<level> causes aptitude to only log messages whose
           level is <level> or higher. For instance, setting the log level to
           error will cause only messages at the log levels error and fatal to
           be displayed; all others will be hidden. Valid log levels (in
           descending order) are off, fatal, error, warn, info, debug, and
           trace. The default log level is warn.

           --log-level=<category>:<level> causes messages in <category> to
           only be logged if their level is <level> or higher.

           --log-level may appear multiple times on the command line; the most
           specific setting is the one that takes effect, so if you pass
           --log-level=aptitude.resolver:fatal and
           --log-level=aptitude.resolver.hints.match:trace, then messages in
           aptitude.resolver.hints.parse will only be printed if their level
           is fatal, but all messages in aptitude.resolver.hints.match will be
           printed. If you set the level of the same category two or more
           times, the last setting is the one that will take effect.

           This does not affect the log of installations that aptitude has
           performed (/var/log/aptitude); the log messages written using this
           configuration include internal program events, errors, and
           debugging messages. See the command-line option --log-file to
           change where log messages go.

           This corresponds to the configuration group
           Aptitude::Logging::Levels.

       --log-resolver
           Set some standard log levels related to the resolver, to produce
           logging output suitable for processing with automated tools. This
           is equivalent to the command-line options
           --log-level=aptitude.resolver.search:trace
           --log-level=aptitude.resolver.search.tiers:info.

       --no-new-installs
           Prevent safe-upgrade from installing any new packages; when the
           safe resolver is being used (i.e., --safe-resolver was passed or
           Aptitude::Always-Use-Safe-Resolver is set to true), forbid the
           dependency resolver from installing new packages. This option takes
           effect regardless of the value of
           Aptitude::Safe-Resolver::No-New-Installs.

           This mimics the historical behavior of apt-get upgrade.

       --no-new-upgrades
           When the safe resolver is being used (i.e., --safe-resolver was
           passed or Aptitude::Always-Use-Safe-Resolver is set to true),
           forbid the dependency resolver from installing upgrades for
           packages regardless of the value of
           Aptitude::Safe-Resolver::No-New-Upgrades.

       --no-show-resolver-actions
           Do not display the actions performed by the 「safe」 resolver,
           overriding any configuration option or earlier
           --show-resolver-actions.

       -O <順序>, --sort <順序>
           Specify the order in which output from the search and versions
           commands should be displayed. For instance, passing 「installsize」
           for <order> will list packages in order according to their size
           when installed (see the section 「Customizing how packages are
           sorted」 in the aptitude reference manual for more information).

           Prepending the order keyword with a tilde character (~) reverses
           the order from ascending to descending.

           The default sort order is name,version.

       -o <キー>=<>
           設定ファイルオプションを直接設定します。例えば -o Aptitude::Log=/tmp/my-log を用いると、aptitude
           のアクションを /tmp/my-log に記録できます。設定ファイルオプションについてのさらに詳しい情報は、aptitude リファレ
           ンスマニュアルの「設定ファイルリファレンス」セクションを参照してください。

       -P, --prompt
           Always display a prompt before downloading, installing or removing
           packages, even when no actions other than those explicitly
           requested will be performed.

           これは設定オプション Aptitude::CmdLine::Always-Prompt に相当します。

       --purge-unused
           If Aptitude::Delete-Unused is set to 「true」 (its default), then in
           addition to removing each package that is no longer required by any
           installed package, aptitude will also purge them, removing their
           configuration files and perhaps other important data. For more
           information about which packages are considered to be 「unused」, see
           the section 「Managing Automatically Installed Packages」 in the
           aptitude reference manual.  THIS OPTION CAN CAUSE DATA LOSS! DO NOT
           USE IT UNLESS YOU KNOW WHAT YOU ARE DOING!

           This corresponds to the configuration option
           Aptitude::Purge-Unused.

       -q[=<n>], --quiet[=<n>]
           すべての進行状況を逐一表示させず、したがって出力を記録可能にします。プログラムの出力をより少なくするために、このオプションを何回も繰り
           返し与えてもかまいません。しかし apt-get とは異なり、aptitude では、-q を複数回与えた場合は -y を与えることは
           できません。

           任意で =<n> をつけると、出力の少なさを直接設定できます (例えば、/etc/apt/apt.conf の設定を上書きするのに利用
           できます)。このときプログラムは、-q をちょうど <n> 回与えたときのように振る舞います。

       -R, --without-recommends
           Do not treat recommendations as dependencies when installing new
           packages (this overrides settings in /etc/apt/apt.conf and
           ~/.aptitude/config). Packages previously installed due to
           recommendations will not be removed.

           This corresponds to the pair of configuration options
           APT::Install-Recommends and APT::AutoRemove::RecommendsImportant.

       -r, --with-recommends
           新しいパッケージをインストールする際に、推奨を依存関係として扱います (これは、/etc/apt/apt.conf および
           ~/.aptitude/config の設定を上書きします)。

           This corresponds to the configuration option
           APT::Install-Recommends

       --remove-user-tag <tag>
           For full-upgrade, safe-upgrade forbid-version, hold, install,
           keep-all, markauto, unmarkauto, purge, reinstall, remove, unhold,
           and unmarkauto: remove the user tag <tag> from all packages that
           are installed, removed, or upgraded by this command as if with the
           add-user-tag command.

       --remove-user-tag-from <tag>,<pattern>
           For full-upgrade, safe-upgrade forbid-version, hold, install,
           keep-all, markauto, unmarkauto, purge, reinstall, remove, unhold,
           and unmarkauto: remove the user tag <tag> from all packages that
           match <pattern> as if with the remove-user-tag command. The pattern
           is a search pattern as described in the section 「Search Patterns」
           in the aptitude reference manual.

           For instance, aptitude safe-upgrade --remove-user-tag-from
           "not-upgraded,?action(upgrade)" will remove the not-upgraded tag
           from all packages that the safe-upgrade command is able to upgrade.

       -s, --simulate
           コマンドラインモードで、通常なら実行されるアクションを、実際には実行せずに表示します。これには root 権限は要りません。ビジュアル
           インタフェースでは、使用者が root であるかないかに関わらず、常に読み取り専用モードでキャッシュを開きます。

           これは設定オプション Aptitude::Simulate に相当します。

       --safe-resolver
           When package dependency problems are encountered, use a 「safe」
           algorithm to solve them. This resolver attempts to preserve as many
           of your choices as possible; it will never remove a package or
           install a version of a package other than the package's default
           candidate version. It is the same algorithm used in safe-upgrade;
           indeed, aptitude --safe-resolver full-upgrade is equivalent to
           aptitude safe-upgrade. Because safe-upgrade always uses the safe
           resolver, it does not accept the --safe-resolver flag.

           This option is equivalent to setting the configuration variable
           Aptitude::Always-Use-Safe-Resolver to true.

       --schedule-only
           パッケージの状態を変化させるコマンドに対して、操作をその場では実行せずに、将来実行するよう設定します。引数を与えずに aptitude
           install を実行すると、設定されたアクションを実際に行うことができます。これは、ビジュアルモードで相当する選択を行ってからプログ
           ラムを正常に終了させるのと等価です。

           例えば、aptitude --schedule-only install evolution を実行すると、evolution パッ
           ケージを後でインストールするよう設定できます。

       --show-package-names <when>
           Controls when the versions command shows package names. The
           following settings are allowed:

           •   always: display package names every time that aptitude versions
               runs.

           •   auto: display package names when aptitude versions runs if the
               output is not grouped by package, and either there is a
               pattern-matching argument or there is more than one argument.

           •   never: never display package names in the output of aptitude
               versions.

           This option corresponds to the configuration item
           Aptitude::CmdLine::Versions-Show-Package-Names.

       --show-resolver-actions
           Display the actions performed by the 「safe」 resolver and by
           safe-upgrade.

           When executing the command safe-upgrade or when the option
           --safe-resolver is present, aptitude will display a summary of the
           actions performed by the resolver before printing the installation
           preview. This is equivalent to the configuration option
           Aptitude::Safe-Resolver::Show-Resolver-Actions.

       --show-summary[=<MODE>]
           Changes the behavior of 「aptitude why」 to summarize each dependency
           chain that it outputs, rather than displaying it in long form. If
           this option is present and <MODE> is not 「no-summary」, chains that
           contain Suggests dependencies will not be displayed: combine
           --show-summary with -v to see a summary of all the reasons for the
           target package to be installed.

           <MODE> can be any one of the following:

            1. no-summary: don't show a summary (the default behavior if
               --show-summary is not present).

            2. first-package: display the first package in each chain. This is
               the default value of <MODE> if it is not present.

            3. first-package-and-type: display the first package in each
               chain, along with the strength of the weakest dependency in the
               chain.

            4. all-packages: briefly display each chain of dependencies
               leading to the target package.

            5. all-packages-with-dep-versions: briefly display each chain of
               dependencies leading to the target package, including the
               target version of each dependency.

           This option corresponds to the configuration item
           Aptitude::CmdLine::Show-Summary; if --show-summary is present on
           the command-line, it will override Aptitude::CmdLine::Show-Summary.

           例12 Usage of --show-summary --show-summary used with -v to display
           all the reasons a package is installed:

           --show-summary used to list a chain on one line:

               $ aptitude --show-summary=all-packages why aptitude-gtk libglib2.0-data
               Packages requiring libglib2.0-data:
                 aptitude-gtk D: libglib2.0-0 R: libglib2.0-data

       -t <リリース>, --target-release <リリース>
           Set the release from which packages should be installed. For
           instance, 「aptitude -t experimental ...」 will install packages from
           the experimental distribution unless you specify otherwise.

           This will affect the default candidate version of packages
           according to the rules described in apt_preferences(5).

           これは設定項目 APT::Default-Release に相当します。

       -V, --show-versions
           パッケージのどのバージョンがインストールされるか表示します。

           これは設定オプション Aptitude::CmdLine::Show-Versions に相当します。

       -v, --verbose
           いくつかのコマンド (例えば show) が付加的な情報を表示するようにします。さらに詳しい情報を得るために、このオプションを何回も繰
           り返し与えてもかまいません。

           これは設定オプション Aptitude::CmdLine::Verbose に相当します。

       --version
           aptitude のバージョンや、そのコンパイル方法に関する情報を表示します。

       --visual-preview
           コマンドラインからパッケージのインストールや削除を行うときに、通常のプロンプトを表示する代わりに、ビジュアルインタフェースを立ち上げて
           そのプレビュー画面を表示します。

       -W, --show-why
           In the preview displayed before packages are installed or removed,
           show which manually installed package requires each automatically
           installed package. For instance:

               $ aptitude --show-why install mediawiki
               ...
               The following NEW packages will be installed:
                 libapache2-mod-php5{a} (for mediawiki)  mediawiki  php5{a} (for mediawiki)
                 php5-cli{a} (for mediawiki)  php5-common{a} (for mediawiki)
                 php5-mysql{a} (for mediawiki)

           When combined with -v or a non-zero value for
           Aptitude::CmdLine::Verbose, this displays the entire chain of
           dependencies that lead each package to be installed. For instance:

               $ aptitude -v --show-why install libdb4.2-dev
               The following NEW packages will be installed:
                 libdb4.2{a} (libdb4.2-dev D: libdb4.2)  libdb4.2-dev
               The following packages will be REMOVED:
                 libdb4.4-dev{a} (libdb4.2-dev C: libdb-dev P<- libdb-dev)

           This option will also describe why packages are being removed, as
           shown above. In this example, libdb4.2-dev conflicts with
           libdb-dev, which is provided by libdb-dev.

           This argument corresponds to the configuration option
           Aptitude::CmdLine::Show-Why and displays the same information that
           is computed by aptitude why and aptitude why-not.

       -w <>, --width <>
           Specify the display width which should be used for output from the
           search and versions commands (in the command line).

           By default and when the output is seen directly in a terminal, the
           terminal width is used. When the output is redirected or piped, a
           very large "unlimited" line width is used, and this option is
           ignored.

           これは設定オプション Aptitude::CmdLine::Package-Display-Width に相当します。

       -y, --assume-yes
           yes/no プロンプトが表示されたときにユーザが「yes」と入力したと仮定します。特に、パッケージをインストール・更新・削除するとき
           に現れるプロンプトを隠します。必須パッケージの削除などといった「危険な」アクションに対するプロンプトはそのまま表示され続けます。このオ
           プションは -P を上書きします。

           これは設定オプション Aptitude::CmdLine::Assume-Yes に相当します。

       -Z
           インストール・更新・削除される各パッケージがどの程度のディスク領域を使用または解放するかを表示します。

           これは設定オプション Aptitude::CmdLine::Show-Size-Changes に相当します。

       以下のオプションがプログラムのビジュアルモードに適用できますが、これらは主に内部で使用するためのものです。あなたがこれらを自分で使う必要は、通
       常はありません。

       --autoclean-on-startup
           Deletes old downloaded files when the program starts (equivalent to
           starting the program and immediately selecting Actions → Clean
           obsolete files). You cannot use this option and
           「--clean-on-startup」, 「-i」, or 「-u」 at the same time.

       --clean-on-startup
           Cleans the package cache when the program starts (equivalent to
           starting the program and immediately selecting Actions → Clean
           package cache). You cannot use this option and
           「--autoclean-on-startup」, 「-i」, or 「-u」 at the same time.

       -i
           Displays a download preview when the program starts (equivalent to
           starting the program and immediately pressing 「g」). You cannot use
           this option and 「--autoclean-on-startup」, 「--clean-on-startup」, or
           「-u」 at the same time.

       -S <ファイル名>
           標準の状態ファイルではなく <ファイル名> から拡張状態情報をロードします。

       -u
           Begins updating the package lists as soon as the program starts.
           You cannot use this option and 「--autoclean-on-startup」,
           「--clean-on-startup」, or 「-i」 at the same time.

環境変数
       HOME
           If $HOME/.aptitude exists, aptitude will store its configuration
           file in $HOME/.aptitude/config. Otherwise, it will look up the
           current user's home directory using getpwuid(2) and place its
           configuration file there.

       PAGERaptitude changelog」が呼び出されたときに、この環境変数が設定されていると、aptitude は更新履歴を表示するの
           にそれを用います。設定されていない場合のデフォルトは more です。

       TMP
           TMPDIR が設定されていなく TMP が設定されている場合、aptitudeTMP に一時ファイルを保存します。そうでない場
           合は /tmp に保存します。

       TMPDIR
           この環境変数で示される一時ディレクトリに aptitude は一時ファイルを保存します。TMPDIR が設定されていない場合、TMP
           が使用されます。TMP も設定されていない場合、aptitude は /tmp を使用します。

FILES
       /var/lib/aptitude/pkgstates
           The file in which stored package states and some package flags are
           stored.

       /etc/apt/apt.conf, /etc/apt/apt.conf.d/*, ~/.aptitude/config
           The configuration files for aptitude.  ~/.aptitude/config overrides
           /etc/apt/apt.conf. See apt.conf(5) for documentation of the format
           and contents of these files.
