windows - How to check the status of all git repositories at once?

Question

Introduction

In order to check the status of git repositores, git status could be issued from the root of a repository.

C:pathogit_repositoriesgit_repo_1>git status
On branch master
Your branch is up-to-date with 'origin/master'.

nothing to commit, working directory clean

If a directory consists of multiple, e.g. 50 git repositories

C:pathogit_repositories>dir

 Directory of C:pathogit_repositories

  .ssh
  git_repo_1
  ...
  git_repo_50

C:pathogit_repositories>git status .
fatal: Not a git repository (or any of the parent directories): .git

neither

C:pathogit_repositories>git status ./.
fatal: Not a git repository (or any of the parent directories): .git

is able to check the status of all repositories

How to check the status of all git repositories at once?

Answer 1

You could use a for loop that changes into each directory, does git status and then changes back up:

for /f "tokens=*" %a in ('dir /ad /b') do cd %a & git status & cd ..

You need to double the percentages if you use this in a batch file:

for /f "tokens=*" %%a in ('dir /ad /b') do cd %%a & git status & cd ..

Edit:

As suggested by Cupcake, you could do this instead:

for /f "tokens=*" %a in ('dir /ad /b') do git --git-dir=%a/.git --work-tree=%a status

This feels like a more robust and flexible solution (e.g. you could adapt it more easily to work with a list of paths stored in a text file).
