The apt-cache search command will return all packages that have name in the package name or description:

apt-cache search name 

Once you have a package name, you can get more detailed information on the package using the apt-cache show and apt-cache showpkg commands.

apt-cache show package_name apt-cache showpkg package_name 

apt-cache search

While both aptitude and apt-cache do the job well, there is a new kid on the block; axi-cache.

axi-cache works a lot like apt-cache, but on steroids. ;) It uses a sophisticated tool called xapian to build an index and then queries that index. It bundles something called in with the index as well. Debtags allow you to create little tags that stick to deb packages. Suffice it to say that debtags are a powerful way to search for packages and tools to get stuff done.

For example, if you wanted a WebDAV client in Debian you could do this;

axi-cache search protocol::webdav 

That search produces this on my machine;

axi-cache search protocol::webdav 14 results found. Results 1-14: 100% gstreamer0.10-gnomevfs - GStreamer plugin for GnomeVFS 100% sitecopy - A program for managing a WWW site via FTP, DAV or HTTP 100% davfs2 - mount a WebDAV resource as a regular file system 100% blosxom - light, feature-packed weblog app with plugin extensibility 100% lighttpd-mod-webdav - WebDAV module for lighttpd 100% nd - small command line interface to WebDAV servers 100% cadaver - command-line WebDAV client 100% subversion-tools - Assorted tools related to Subversion 100% libapache2-svn - Subversion server modules for Apache 100% libcommons-vfs-java - Java API for accessing various filesystems 100% subversion - Advanced version control system 100% eldav - interface to the WebDAV servers for Emacs. 100% libhttp-dav-perl - WebDAV client library for Perl, and "dave" CLI client 100% fusedav - filesystem to mount WebDAV shares More terms: webdav servers authoring versioning files subversion remote More tags: network::client protocol::http role::program implemented-in::c interface::commandline protocol::ftp devel::rcs 

As you can see a lot of tools show up which is quite handy if you're not really sure what you are looking for but you know for example the problem area you're looking at.

Install aptitude, them it's just aptitude search xyz for a list of packages with xyz in their name or one-line description.

sudo apt list package_name sudo apt search text_to_search_for_in_all_package_fields 

As root:

apt-get search <package name> 

If you didn't know about this, it is usually a good idea to run:

command --help 

to see how you can you use the command. that or look at the man pages using

man <command>
