Search For Specific Packages

Terminal:~$

sudo aptitude search ~ipackagename

sudo aptitude search ~igoogle

Search Results

Terminal:~$

sudo aptitude search package-name

This will return similar to the following:

Terminal:~$

p   aptitude:i386     - terminal-based package manager                                           
i A aptitude-common   - architecture independent files for the aptitude package manager

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
  • 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:

  • i - meaning that the package will be installed (the most common)
  • d - meaning that the package will be deleted
  • p - meaning that the package and its configuration files will be removed.

If the third character is A, the package was automatically installed.

Purging Config Files

If a search result displays a 'c' this shows that the package was deleted but its configuration files remain on the system, for example:

Terminal:~$

c   libvlc5           - multimedia player and streamer library

To purge the files:

 Terminal:~$

sudo aptitude purge libvlc5
