The program 'mc' is currently not installed. You can install it by typing:

Come posso ottenere dettagli sul programma 'mc' prima di installarlo? Voglio confermare che quello è il file che voglio e non un altro.

Il modo più veloce è usare un terminale apt-cachee un po 'di fiducia ;)

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.

Usando la GUI puoi aprire "Ubuntu Software Center" e cercare mco Midnight Commander.
Ti darà una descrizione completa del pacchetto. È anche utile se non si conosce il nome esatto del pacchetto.
Inoltre puoi installare Synaptic e fare una ricerca simile lì.
Il software può essere installato anche in Software Center o Synaptic senza utilizzare la riga di comando.
Ci sono molti modi per farlo. Il più semplice per impostazione predefinita è apt-cache search.
apt-cache search <regex>
Ti darà qualcosa del genere:
$ 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
Questo è in qualche modo equivalente a:
dpkg-query -Wf '${Package} ${binary:Summary}\n'
dpkg-querySolo che sembra funzionare solo su cose che hai già installato.
apt listha una ricerca glob (piuttosto che regex) che è un po 'più naturale per la maggior parte degli utenti ma non è ancora possibile modificare il formato di output. Tuttavia, avendo esaminato la fonte , è possibile generare il riepilogo:
$ apt list -o 'APT::Cmd::List-Include-Summary=1' *cheese*
