How about using git fetch instead?

[rofrol]

for example this is how I update default branch without switching to it:

git fetch -f . "$REMOTE_AND_BRANCH":"$BRANCH"

or with the script git fm

Hi @rofrol ,

thanks for taking the time to report a possible improvement.

Thanks for the suggestion to use git fetch to get the default branch!

I'd like to avoid a remote call for the git operation. But maybe I can cache this information.

I'll think about it and come back to this.

Best regards, Christoph

but this is local call git fetch -f . when using dot .
