Remove All Unused Ubuntu Kernel Images, Headers, and Modules
Seeing that my linux box is running low on free space I decided to remove all unused Linux kernel images on my Ubuntu 10.04 system.
dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge
If you don't understand what this command does I recommend to dig into the topic. I must admit it is a little bit complex, but the command is working well.
Use it at your own risk!
Now my system is cleaned up and still boots the correct and latest kernel. All other kernel images, headers and modules are completely removed.
