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

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).

I went with:

find . -name .git -execdir bash -c 'echo -en "\033[1;31m"repo: "\033[1;34m"; basename "`git rev-parse --show-toplevel`"; git status -s' \;

I think it's nicer because treats directories recursively.

Edited to show the name of the repo in a cleaner way.

If you are a kind of a tool-guy, you could use a little helper called RepoZ I wrote recently (and still write).

I answered a quite similar question in more detail here.

Here's a screenshot from the current development stage so hopefully you can see whether it seems helpful to you or not:

If you are wondering what that strings like +45 ~403 -88 mean - they are condensed status strings telling you whether there are commits to fetch or push and whether there are added/modified/deleted files locally. More detail on the project site on GitHub
