Get the name of the remote tracked branch of my local branch for use in script

Can I programmatically get the name of the remote branch which my local branch is tracking?

I'm interested in scripting around git-range-diff(1), so that I could do something like this:

[alias]
    rd = range-diff master..REMOTE_BRANCH remote1/master..HEAD

and then be able to run on the command line git rd to get a range diff between the remote state of my branch and the local one (represented by HEAD).

What should I put in REMOTE_BRANCH to make this work?

I'm not exactly sure what you want with the whole of rd, but

…programmatically get the name of the remote branch which my local branch is tracking…

sounds very much like the @{upstream}/@{u} shortcut. You can provide a branch before it to refer to the tracked remote of that branch, or leave it bare to refer to the tracked remote of the branch you currently have checked out.

If remote1 is actually the tracking remote for master, you could even write the alias as

[alias]
    rd = range-diff master..@{u} master@{u}..HEAD

Purpose of the rd alias
alx‭ wrote about 10 hours ago

The purpose of the rd alias is that as a contributor/comaintainer of a given project (in this specific case I'll be using it, the shadow-utils project), I have many branches as pull requests. Whenever something is merged into master, I rebase my branches. And for showing the reviewers the changes between revisions, I show them the list of changes as a git-range-diff(1), I do this operation very often (yesterday, around 20 times), and it gets tedious to type the right branches, when the alias could just do it for me. :)
