[...] Opposed to some other replies I have to say that dpkg -l (or --list) does *not* show installed packages only. It also shows you packages which have already been removed but their respective configuration remained. But one can filter those out: $ dpkg -l | grep ^ii | less But this method lacks some informations you asked for. Again my preference lies on aptitude: $ aptitude show ~i | less This will show the same list as the above $ aptitude show package name for all installed packages. If you like to use graphical tools, then you can use the interactive mode of aptitude (aptitude called with no arguments) on the console, or you can give Synaptic a try as it was already suggested.

problem searching packages
Hi there ! Newcomer on Debian (former user of RedHat 7.2), I find the Debian packages kind of hard to manage. With RedHat rpm, I could find very easily whether a package was installed or not, what was the version number etc.. With Debian, I have not yet found the way to go ; I suppose that I should read a greater number of pages, but there is so much doc that it is not easy to find the right one right away. #apt-cache search package_name gives me some information on said package, but not the version number. In fact, I suspect that this command does not read in my local base, but in the distant servers, so that I don't know if a given package is being installed on my system or not. For instance : #apt-cache search hplip lists a number of related packages that, I think, are supposed de operate together... but this does not tell me whether hplip is installed or not in my system. I think it is not installed, since #man hplip tells me that there is no manual entry for hplip. In fact, hplip has been in turn installed, removed, re-installed and re-removed on my system, so it should not be there at this time, except if I got mixed up somewhere. I can't remember what hplip version I had, and I don't plan to reinstall blindly as I had done before. Now, if I try #dpkg -I hplip I get : dpkg-deb: unable to read the archive hplip, no file or directory of this type. But, if I try the same command with cups or gimp as arguments, I get the same kind of answers, despites that cups and gimp are properly installed. I imagine that I should write, as an argument, not a guessed package name such as 'gimp', but a real package name with a version number and .deb in the end... but where am I to find such information on debian packages ? My first question will be : How to check whether hplip (or any other package) is installed on my system or not ? The second question : how to investigate what packages are installed in my system, with all informations (package name, version etc...)
