Re: How to prevent empty git commit --amend

Is there a way to prevent a *git commit --amend** with nothing to
commit from working?
If not, I would like to suggest that this feature would be very helpful :)

I don't know any way to let Git do the check for you, but 

git diff --staged --quiet || git commit --amend

should do it. You can alias it like

[alias]
	amend = !git diff --staged --quiet || git commit --amend

and then use "git amend".

That would not let you say "git amend Makefile", no?

	!sh -c 'git diff --cached --quiet "$@" || git commit --amend "$@"' -

or something, perhaps?
