How to check if remote branch exists on a given remote repository?
I need to do a subtree merge for a specific branch, if it exists on a given remote repository. The problem is that the remote repository is not checked out locally, so I can't use git branch -r . All I have is a remote address, something like this https://github.com/project-name/project-name.git . Is there a way to list remote branches just by a remote address? I couldn't find anything usefull :(
In fact you can also specify the name of the branch you are searching for:
$ git ls-remote --heads git@github.com:user/repo.git branch
In case branch with name branch is found you will get the following output:
b523c9000c4df1afbd8371324083fef218669108 refs/heads/branch
Otherwise no output will be sent.
So piping it to wc will give you 1 or 0 :
$ git ls-remote --heads git@github.com:user/repo.git branch | wc -l
Alternatively you can set --exit-code flag on git ls-remote which will return exit code 2 in case no matching refs are found.

您可以在当前文件夹中使用的另一种方式，如果它是运行git repo
git branch -a | egrep 'remotes/origin/${YOUR_BRANCH_NAME}$'
