Finding the attributes of a package in Ubuntu


i want to find and print all attributes of a package using python. I'm using ubuntu and developing in python. I can search and find all packages. FOr example one these packages is "eclipse-cdt". I want to develop a code giving the attributes of this package, such as, isInstalled, isUpdateable, versionNumber, dependentPackages etc. How can i do this?

Thanks in advance


Solution

  • apt-cache yields a lot of information about a package, e.g.:

    apt-cache show bash
    
    Package: bash
    Version: 4.3-12
    Essential: yes
    Installed-Size: 5367
    Maintainer: Matthias Klose <doko@debian.org>
    Architecture: amd64
    Replaces: bash-completion (<< 20060301-0), bash-doc (<= 2.05-1)
    Depends: base-files (>= 2.1.12), debianutils (>= 2.15)
    Pre-Depends: dash (>= 0.5.5.1-2.2), libc6 (>= 2.15), libncurses5 (>= 5.5-5~), libtinfo5
    Recommends: bash-completion (>= 20060301-0)
    Suggests: bash-doc
    Conflicts: bash-completion (<< 20060301-0)
    Description-en: GNU Bourne Again SHell
    ...
    

    You can get a list of packages that will be upgraded with:

    apt-get --just-print upgrade
    

    However, don't reinvent the wheel. There's a quite complete Python library to access APT:
