Kernel Source updater script

Kernel Source updater script

[Matteo Croce]

Hi all,

I know that this is useless to people using git, but it was so fun to write
and I use it to update regularly my pc kernel source from time to time
while saving servers (and home) bandwidth

cheers!

#!/bin/sh

ver=$(awk '/^VERSION/{print$3}' Makefile)
patch=$(awk '/^PATCHLEVEL/{print$3}' Makefile)
sub=$(awk '/^SUBLEVEL/{print$3}' Makefile)

echo "Current kernel: $ver.$patch.$sub"

[ -d .pc ] && quilt pop -a

up_sub() {
	next=$((sub + 1))
	while wget -q --spider
http://www.kernel.org/pub/linux/kernel/v$ver.0/incr/patch-$ver.$patch.$sub-$next.xz;
do
		url="$url http://www.kernel.org/pub/linux/kernel/v$ver.0/incr/patch-$ver.$patch.$sub-$next.xz"
		sub=$next
		next=$((next + 1))
	done

	echo "Upgrading to version: $ver.$patch.$sub"

	wget -qO- $url |xz -d |patch -p1 |sed -u 's/$/
                  /' |tr '[\n]' '[\r]'
	echo

up_patch(){
	if [ $sub -gt 0 ]; then

Have you looked at the python script called 'ketchup'?  I think it
already does a lot of what you are doing here.

I tried to get it to work with 3.x kernels, and I don't think I was
successful. Hopefully someone else did the job?

It would be nice to include it in the scripts/ directory, to save
duplicate work. (Or drivers/staging/scripts? :-).
