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.
