通过一个Git远程跟踪分支的名字如何找到本地分支跟踪它？

Question

By a given name of a Git remote-tracking branch, for example, upstream/develop how to find which local branch tracks it if any?

If possible I'm looking for a solution that not relies on shell scripting and also works on Windows.

Answer 1

An alternative is to use a conditional format with for-each-ref

git for-each-ref --format="%(if:equals=upstream/develop)%(upstream:short)%(then)%(refname:short)%(end)" refs/heads | sort -u

which could be more conveniently put into an alias like

git config --global alias.who-tracks '!f() { git for-each-ref --format="%(if:equals=upstream/$1)%(upstream:short)%(then)%(refname:short)%(end)" refs/heads | sort -u; }; f'

# then when you need it :
git who-tracks develop
git who-tracks another/branch

In this alias, I assumed a unique remote, but of course if you want to be able to use it on different remotes, tweak a little bit to include the remote name in the parameter:

git config --global alias.who-tracks '!f() { git for-each-ref --format="%(if:equals=$1)%(upstream:short)%(then)%(refname:short)%(end)" refs/heads | sort -u; }; f'

# then when you need it :
git who-tracks upstream/develop
git who-tracks origin/another/branch

Answer 2

Another alternative is to filter the very verbose output of the simple git branch with grep

git branch -vv | grep upstream/develop

Answer 3

Based on this answer (branch enumeration) and this answer (retrieving upstream branch), you can iterate through local branches and check if any of them has the desired tracking remote branch:

git for-each-ref --shell \
  --format='test %(upstream:short) = "upstream/develop" && echo %(refname:short)' \
  refs/heads/ | sh
