提取git提交中更改的所有文件

Question

I need to make a patch for someone (they are not using git) - a zip of the files changed by a commit.

I thought something like

git archive --format=zip commitguid > myfiles.zip

but this extracts the entire thing, not just the changed files. Is there any way to do this? And to make it more complicated - is there any way of doing this with multiple commits (yes I should have branched before making the changes but that's hindsight)

EDIT

Based on @Amber solution below I can do this in 2 steps in Git Bash for windows with 7Zip installed in c:\\data\\progs.

git diff --name-only a-sha b-sha > tmp.txt
/C/data/progs/7za.exe a myzip.zip @tmp.txt

Answer 1

git diff --name-only <oldsha> <newsha> | zip dest.zip -@

filling in the proper SHAs/refs. For instance, to create a zip of only the files that changed between the master and feature branches:

git diff --name-only master feature | zip dest.zip -@

Answer 2

See also git help format-patch . It produces a diff patch of all changes in a commit along with commit author, date, message, and some nice diff stats. You could zip and send that.
