[Solved] Looking for folders containing valid git bare repositories

Question

You should detect them the way Git detects them, which is outlined in the answer you quoted. To wit, you need the following:

an objects/ directory;
a refs/ directory; and
either a HEAD symlink or a HEAD file that is properly formatted.

The exact specification is documented in the source code in setup.c.

If you have what you suspect is a Git repository, you can change into it and run git rev-parse --git-dir, which will exit successfully if you’re in a Git repository, and exit unsuccessfully if you’re not. You can also use git rev-parse --is-bare-repository and look for either true or false to determine whether your repository is bare.

If you don’t want to change into the repository, you can use git -C <DIR> rev-parse --git-dir and similar to operate on the mentioned directory instead.
