How to know what differences that "git push" is going to push?

Question

After I have git add, and git commit, my workspace, index cached, and local repository became the same. So how can I know when I "push", what differences are there in this patch set?

Answer 1

In conjunction with git-diff

git diff origin/master [ <local-branch-name> ]

you might be looking for

git push --dry-run --verbose

This will simulate a push and print all information you need on the way. From the git man page:

git-push:
-v
--verbose

    Run verbosely.

-n
--dry-run

    Do everything except actually send the updates.
