This patch will remove old kernels and modules directorey related
to that kernel from the system by interactively and silently.Here
are few interactions with the scripts
1)
✔ ~/git-linux/linux-kbuild [master|AM 1/1 ↑·59|✔]
14:52 $ ./scripts/prune-kernel -h
Usage: prune-kernel [ri]
-r | --remove kernel_ver modules_dir_name
-i | --interactive use as interactive way
✘-1 ~/git-linux/linux-kbuild [master|AM 1/1 ↑·59|✔]
14:52 $ ./scripts/prune-kernel --help
Usage: prune-kernel [ri]
-r | --remove kernel_ver modules_dir_name
-i | --interactive use as interactive way
2)
✘-1 ~/git-linux/linux-kbuild [master|AM 1/1 ↑·59|✔]
14:52 $ ./scripts/prune-kernel -r 5.3.3
You need to provide kernel version and modules dir name
✘-1 ~/git-linux/linux-kbuild [master|AM 1/1 ↑·59|✔]
14:53 $ ./scripts/prune-kernel -r
You need to provide kernel version and modules dir name
✘-1 ~/git-linux/linux-kbuild [master|AM 1/1 ↑·59|✔]
14:54 $ ./scripts/prune-kernel -r 5.3.3 5.3.3-foo
3)
$ ./scripts/prune-kernel --remove
You need to provide kernel version and modules dir name
✘-1 ~/git-linux/linux-kbuild [master|AM 1/1 ↑·59|✔]
14:55 $ ./scripts/prune-kernel --remove 5.3.3
You need to provide kernel version and modules dir name
✘-1 ~/git-linux/linux-kbuild [master|AM 1/1 ↑·59|✔]
14:55 $ ./scripts/prune-kernel --remove 5.3.3 5.3.3-foo
4)14:55 $ ./scripts/prune-kernel -i
Enter kernel version to remove or blank/empty to exit:
5)14:57 $ ./scripts/prune-kernel --interactive
Enter kernel version to remove or blank/empty to exit:
✔ ~/git-linux/linux-kbuild [master|AM 1/1 ↑·59|✔]
6)14:59 $ ./scripts/prune-kernel --interactive
Enter kernel version to remove or blank/empty to exit:5.3.3
Please give the full modules directory name to remove:5.3.3-foo
Removed kernel version:5.3.3 and associated modules:5.3.3-foo ...Done.
7)15:00 $ ./scripts/prune-kernel -i
Enter kernel version to remove or blank/empty to exit:5.3.3
Please give the full modules directory name to remove:5.3.3-foo
