  • 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)}')
