git branch --create branchname works fine, but is not documented anywhere

git branch branchname creates new branch "branchname", we know that.

However,

git branch --create branchname also creates new branch "branchname":

yet the latter is not documented anywhere, not even in git docs.

I usually don't trust ChatGPT, but out of the curiosity, I've asked the same question to it, and it also says, that there is no git branch --create branchname.

This is weird.

Any tips?

4 It's implied to be the longest form --create-reflog, I guess? You can shorten long option names as long as it's unique – Romain Valeri Commented Mar 17 at 14:37

2 @RomainValeri is correct according to my testing. (1) git branch <branch> creates a branch (2) --create-reflog is an option you can provide (3) you can shorten that option to --create or --create-r (however short as long as it is not ambigious) (4) git branch --create <branch> is the same as git branch --create-reflog <branch>. – Guildenstern Commented Mar 17 at 14:46
2 @UlrichEckhardt that is exactly the question for SO, and it was answered quickly. So, you're downvoting because there is no discrete StackExchange page and I've asked it here?.. look around SO, and you'll find question way off the topic of programming that git.. weird downvotes are happening here! – Gii Tsiklauri Commented Mar 17 at 15:06
2 @UlrichEckhardt It's often said in a joking tone, but seriously here, it's not a bug, it's a feature! It is documented. See the link I shared above. – Romain Valeri Commented Mar 17 at 15:11

Your git branch --create foo is assumed by git to be git branch --create-reflog foo because no other option starts with --create

As confusing as it can be to quite a lot of people, it's git's way to interpret incomplete option names.

One can abbreviate long options as long as it's unique. (doc)
