I'm not much of a unix guy so I'll just go ahead and ask:
I have a following problem - two folders with plenty of subfolders. I need to diff them.
I tried this:
diff -drupN vanila_kernel_3.0.8 my_kernel_3.0.8 > kernel.patch
and that results in a 85mb file... and not really what I want.
I want the result of the diff to be many smaller patches, ideally one for every changed file with the contents of the change. That means I have t ochange the way I use diff, and I need to put it in some sort of a loop... So i tried running this little script
for file in original_308/*.*; do
diff -dupN "$file" "my_308/${file##*/}" > "$file".patch
done
But it doesn't work :/
Ideally, I want to have a .patch file for every change, but having patches for files that changed in original would do just fine (as I could filter the newly added files and just copy them over)
Can someone provide me with a decent way to do this please?
EDIT:
Here's something choroba asked me to post
diff -Naur -x '*.o' -x '*.cmd' -x '*.d' original_308/arch/arm/boot/compressed/head.S my_308/arch/arm/boot/compressed/head.S

So yes, it is the proper output even though gedit/geany cannot open it. UltraEdit does...
