This patch will remmove old kernel and associated modules directory from
the system.
Few interaction with the script ,below
1) ✔ ~/git-linux/linux-kbuild [master ↑·18|✔]
10:40 $ ./scripts/prune-kernel
2)10:41 $ ./scripts/prune-kernel -h
You need to use this script like this :
./scripts/prune-kernel -r kernel_version modules_directory_name
./scripts/prune-kernel -i option for interactive way to use it.
3) 10:41 $ ./scripts/prune-kernel -r 5.2.2 5.2.2-gentoo
Removed kernel version:5.2.2 and modules directory:5.2.2-gentoo from
the system.
4)10:41 $ ./scripts/prune-kernel -i
Want to removing old kernels and modules dir [YN]: Y
Please give another version to remove: 5.2.2
/boot/vmlinuz-5.3.7-050307-generic
/boot/vmlinuz-5.3.6-050306-generic
find: ‘/boot/efi’: Permission denied
Please give the full modules directory name to remove: 5.2.2-gentoo
5.3.6-050306-generic
5.3.7-050307-generic
Removed kernel version:5.2.2 and associated modules:5.2.2-gentoo
..Done.
