Git Force push syntax, “-f” versus “+branch”
What is the difference between these two git commands when force pushing changes?
git push -f origin branch and git push origin +branch
If you’re only pushing one branch, there is no difference.
git push -f origin branch
git push origin +branch
are exact equivalents. The difference arises when you’re pushing more than one branch with a single
In a nutshell, the optional
+ gives you finer control than
-f does: if you’re pushing more than one ref at a time, the
+ allows you to specify which of the pushed refs get force-pushed, whereas
-f) applies to all the refs that are getting pushed.
git-push man page tells you
The most basic form of
git push that involve one or more refspec(s) is
git push <repository> <refspec>...
The form that the
<refspec>... argument must satisfy is described in the
git-push man page thus:
Specify what destination ref to update with what source object. The format of a `<refspec>` parameter is an optional plus `+`, followed by the source object `<src>`, followed by a colon `:`, followed by the destination ref `<dst>`.
So, just to be clear, the syntax for
:<dst> is omitted, the same ref as
<src> will be updated… unless the
remote.<repository>.push entry (if any) in your Git config says otherwise.
Further down in the
git-push man page, you find
By having the optional leading
+, you can tell Git to update the
ref even if it is not allowed by default (e.g., it is not a
fast-forward.) This does not attempt to merge
And still further down:
--forceapplies to all the refs that are pushed, hence

destinations configured with
remote.*.pushmay overwrite refs other
than the current branch (including local refs that are strictly behind
their remote counterpart). To force a push to only one branch, use a

Consider a local repo with two branches,
develop, which you want to push (with a single
git push command) to an
git push origin master developwill push both branches, but neither will get force-pushed.
git push origin +master developwill push both branches, but only
masterwill get force-pushed.
git push origin master +develop, conversely, will push both branches, but only
developwill get force-pushed.
git push origin +master +developwill force-push both branches. It’s an exact equivalent to
git push -f origin master develop.
