purge-old-kernels

purge-old-kernels [--keep N] [apt-get options...]

purge-old-kernels removes old Linux kernel and header packages from Ubuntu and Debian systems to reclaim disk space, particularly in the /boot partition. Over time, kernel upgrades accumulate previous versions that are no longer needed, and this utility automates their safe removal. It will never remove the currently running kernel.By default the tool keeps the 2 most recent kernels, configurable with the --keep option. Any additional arguments are passed directly to apt-get(8), so -s can be used for dry-run simulation and -y to skip confirmation. The command is part of the byobu package on Ubuntu/Debian systems and requires root privileges.Note: This utility is now deprecated. Its functionality is expected to be integrated into apt(8).

--keep N

Number of old kernels to keep. Defaults to 2.

Any additional arguments are passed directly to apt-get(8). Common examples: -y (assume yes), -s (simulate/dry-run), -q (quiet).

Ubuntu/Debian specific. Requires root. The currently running kernel is never removed. Now deprecated in favor of apt(8) integration.

purge-old-kernels was created for Ubuntu kernel package cleanup.
