14.04 Ubuntuターミナルで「mc」と入力すると、
The program 'mc' is currently not installed. You can install it by typing:
sudo apt-get install mc
インストールする前に、プログラム 'mc'の詳細を取得するにはどうすればよいですか？私はそれが私が望むファイルであって、他のファイルではないことを確認したい。
パッケージの詳細を取得してからインストールしますか？

最速の方法は、端末とapt-cache少し信頼 を使用することです;）

Description-en: Midnight Commander - a powerful file manager
GNU Midnight Commander is a text-mode full-screen file manager. It
uses a two panel interface and a subshell for command execution. It
includes an internal editor with syntax highlighting and an internal
viewer with support for binary files. Also included is Virtual
Filesystem (VFS), that allows files on remote systems (e.g. FTP, SSH
servers) and files inside archives to be manipulated like real files.

Description: terminal-based package manager
aptitude is a package manager with a number of useful features, including: a mutt-like syntax for matching packages in a flexible manner, dselect-like persistence of user actions, the ability to retrieve and display the Debian
changelog of most packages, and a command-line mode similar to that of apt-get.
aptitude is also Y2K-compliant, non-fattening, naturally cleansing, and housebroken.

これを行う方法はたくさんあります。最も簡単なデフォルトではありますapt-cache search。
apt-cache search <regex>
次のようになります。
$ apt-cache search cheese
cheese - tool to take pictures and videos from your webcam
gir1.2-cheese-3.0 - tool to take pictures and videos from your webcam - gir bindings
libcheese-dev - tool to take pictures and videos from your webcam - base dev
libcheese-doc - tool to take pictures and videos from your webcam - documentation
libcheese-gtk-dev - tool to take pictures and videos from your webcam - widgets dev
libcheese-gtk23 - tool to take pictures and videos from your webcam - widgets
libcheese7 - tool to take pictures and videos from your webcam - base library
cheese-common - Common files for the Cheese tool to take pictures and videos
python-pyip - Python modules for raw ip packet assembling/disassembling
これは次のようなものです。
dpkg-query -Wf '${Package} ${binary:Summary}\n'
それ以外は、dpkg-query既にインストール済みのものに対してのみ機能するようです。
apt list（正規表現ではなく）glob検索があります。これはほとんどのユーザーにとって少し自然ですが、出力形式を（まだ）変更することはできません。ただし、ソースを確認した後、要約を出力できます。
$ apt list -o 'APT::Cmd::List-Include-Summary=1' *cheese*
Listing... Done
