      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.

               Note
               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”.
           Unless you pass the -F option, the output of aptitude search will look something like this:

               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

           Each search result is listed on a separate line. The first character of each line indicates the current state of the package: the most
           common states are p, meaning that no trace of the package exists on the system, c, meaning that the package was deleted but its
           configuration files remain on the system, i, meaning that the package is installed, and v, meaning that the package is virtual. The
           second character indicates the stored action (if any; otherwise a blank space is displayed) to be performed on the package, with the
           most common actions being i, meaning that the package will be installed, d, meaning that the package will be deleted, and p, meaning
           that the package and its configuration files will be removed. If the third character is A, the package was automatically installed.

           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.
