Remove old Ubuntu- / Debian kernel images
#!/bin/bash KEEP=2 CURRENT=$(uname -r) KERNELCOUNT=$(dpkg -l linux-image-3* | grep ii | wc -l) KERNELS=$(dpkg -l linux-image-3* | grep ii | cut -d' ' -f 3) REMOVECOUNT=$((KERNELCOUNT-KEEP)) REMOVEKERNELS=$(dpkg -l linux-image-3* | grep -v $CURRENT | grep ii | cut -d' ' -f 3 | head -n $REMOVECOUNT) if [ $REMOVECOUNT -le 0 ]; then echo "I was told to keep $KEEP kernel revisions (including current version), but only $KERNELCOUNT kernels are installed. Exiting now." exit 1 fi echo "Currently running on kernel $CURRENT, found $KERNELCOUNT installed kernels:" echo "$KERNELS" echo "I was told to keep $KEEP kernel revisions (including current version), so i will remove $REMOVECOUNT old kernel packages." echo echo "About to purge kernel versions:" echo $REMOVEKERNELS echo apt-get purge $REMOVEKERNELS
Make sure to be running the latest kernel image that is installed on your system! (also, use at your own risk)
