find all git repositories (and git working directories) starting from the current directory and perform a 'git fsck' on them.

list_git_dir.py

import contextlib
import os
import subprocess
from datetime import datetime

# performing git fsck(file system check) seems slower, so I mane this hack
# still can be found on it's upstream or here : https://gist.github.com/neingeist/7d448e574e9da30b6bcd

def git_directories(startdir):
    for dirpath, dirnames, _ in os.walk(startdir):
        if set(['info', 'objects', 'refs']).issubset(set(dirnames)):
            yield dirpath


@contextlib.contextmanager
def working_directory(directory):
    saved_cwd = os.getcwd()
    os.chdir(directory)
    yield
    os.chdir(saved_cwd)

def remote_v(directory):
    file = open("config","r")
    for line in file :
        if ".git" in line:
            print(line)
            # add correct path for you - where you want to log your data
            with open('D:\git_log.txt', 'a') as logfile:
                #print(datetime.now())
                logfile.write(directory+" -M- "+ str(datetime.now()) + " -M- "+line)


for git_directory in git_directories('.'):
    with working_directory(git_directory):
        print('\n{} : '.format(os.getcwd()))
        remote_v(os.getcwd())
        # it will produce some extra upstream location such as [lfs], [hooks], [and some submodule links]
