  • dpkg: purge all packages matching some name

    Recently in Debian Wheezy the dpkg command refuses to work with wildcards, so this is the one-liner alternative. (alternative to #13614)

    sudo dpkg -P $(dpkg -l yourPkgName* | awk '$2 ~ /yourPkgName.*/ && $1 ~ /.i/ {print $2}')

  • Remove all unused kernels with apt-get

    Same as 7272 but that one was too dangerous so i added -P to prompt users to continue or cancel Note the double space: "...^ii␣␣linux-image-2..." Like 5813, but fixes two bugs: [1]This leaves the meta-packages 'linux-headers-generic' and 'linux-image-generic' alone so that automatic upgrades work correctly in the future. [2]Kernels newer than the currently running one are left alone (this can happen if you didn't reboot after installing a new kernel).


    -1
    sudo aptitude remove -P $(dpkg -l|awk '/^ii linux-image-2/{print $2}'|sed 's/linux-image-//'|awk -v v=`uname -r` 'v>$0'|sed 's/-generic//'|awk '{printf("linux-headers-%s\nlinux-headers-%s-generic\nlinux-image-%s-generic\n",$0,$0,$0)}')

mhwd ? Manjaro Hardware Detection
One base component is our hardware detection. It is a C++ library and app and is designed after a dynamic structure. Any kind of hardware, no matter if usb or pci, can be configured by mhwd. There is just a simple configuration file which tells mhwd what to do. This way we also support hybrid graphics cards out of the box. However there are currently only mhwd configs for nvidia optimus setups. But this gap will be filled soon. Just play with some of those commands to get a feeling about mhwd.
