Cheat Sheet for dpkg/apt-get

  • Apt/Dpkg: Beyond the basic use of installing programs, apt and dpkg have many features that are useful for packaging.
    • apt-cache dump - lists every package in the cache. This command is especially helpful in combination with a grep pipe such as apt-cache dump | grep foo to search for packages whose names or dependencies include “foo”.
    • apt-cache policy - lists the repositories (main/restricted/universe/multiverse) in which a package exists.
    • apt-cache show - displays information about a binary package.
    • apt-cache showsrc - displays information about a source package.
    • apt-cache rdepends - shows reverse dependencies for a package (which packages require the queried one.
    • dpkg -S - lists the binary package to which a particular file belongs.
    • dpkg -l - lists currently installed packages. This is similar to apt-cache dump but for installed packages.
    • dpkg -c - lists the contents of a binary package. It is useful for ensuring that files are installed to the right places.
    • dpkg -f - shows the control file for a binary package. It is useful for ensuring that the dependencies are correct.
    • grep-dctrl - searches for specialized information in packages. It is a specific use of the grep package (but not installed by default).

Dublin..



A bumpy flight into Dublin. Quite some rain and clouds and occasional sun rays. A long night out in a pub that challenged me by hiding. Needed to clear my head the day after. Went on a long walk in Dublin bay. Luckily this part of Ireland wasn't affected by the flood. Rushed to meet up for a coffee in heavy rainfalls. The ticket machine refused to serve me. Had to face the Dublin traffic and the rain. Went to a friend's home and finally also met their little one. Have never seen a kid smiling that much. Extremely charming. An early start the next day. A very friendly taxi driver. Got deep-freezed at the gate and almost blown off my feet when entering the plane. Were held on the ground for an hour due to the gusts. Then the familiar culture shock at Nuremberg train station. Anyway, back home. Almost forgot: Hope to go back for the gorilla advertisement. Here are some pics of the short trip:
