Force git to run post-receive hook, even if everything is “up-to-date”

Question

How do I force git to run a post-receive hook on a server even if I don\'t have a new commit to push?

Background

I use git to aut

Answer 1

Use '--allow-empty'

After the initial push replacing the script, you can do this :

git commit --allow-empty -m 'push to execute post-receive'

The --allow-empty flag overrides git's default behavior of preventing you from making a commit when there are no changes.

Use an alias and make your life even easier

Add the following to ~/.gitconfig

[alias]
    pushpr = "!f() { git push origin master;git commit --allow-empty -m 'push to execute post-receive';git push origin master; }; f"

Now Just do git pushpr

git pushpr

This will push any changes to master, which in your case will trigger your post receive replacement script, then it will push again (using the --allow-empty flag) which will then execute your updated post-receive script.
