Using Git to create an archive of changed files

Question

I am looking for a simple solution to make a archive of recent changed file.

I get this simple command from google

git archive -o update.zip HEAD $(git diff --name-only HEAD^)

When I run it in GIT BUSH, it keeps saying saying fatal: Not a valid object name

Answer 1

I'm using this answer in that case that tells me to

tar czf changed-files.tar.gz `git diff --name-only [diff options]`

For example, to create an archive containing the files changed in the last four revisions, I'd do

tar czf changed-files.tar.gz `git diff --name-only HEAD~4..`

This assumes – of course – that HEAD~4 does actually exist.
