** git镇楼：git config --global core.filemode false**

如何利用python执行bash脚本？
如何像cd xxx/一样任性跳转目录执行bash命令？

这两个问题解决了，才算是解决了使用python脚本执行bash命令的全部痛点。

一一解答：

如何利用python执行bash脚本？

os.popen(bash_comand)即可

如何像cd xxx/一样任性跳转目录执行bash命令？

os.chdir(path)就如同cd xxx/一般，可以任性地切换到任意目录

于是，就有了如下代码：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# @name   : find_t.py
# @author : cat
# @date   : 2017/8/2.

import os
import time

def bash_shell(bash_command):
    """
    python 中执行 bash 命令
    :param bash_command:
    :return: bash 命令执行后的控制台输出
    """
    try:
        return os.popen(bash_command).read().strip()
    except:
        return None


def find_target(target_path="./../", key='.git'):
    """
    查找目标目录所在的目录 ： 如 ／aa/bb/.git --> return /aa/bb/
    :param target_path:
    :param key: target
    :return:
    """
    walk = os.walk(target_path)
    for super_dir, dir_names, file_names in walk:
        for dir_name in dir_names:
            if dir_name == key:
                dir_full_path = os.path.join(super_dir, dir_name)
                # print(dir_full_path, super_dir, dir_name, sep=" ## ")
                yield super_dir


if __name__ == '__main__':
    print("start execute bash ...........")
    st = time.time()
    cwd = os.getcwd()
    # this for repo
    for repo_path in find_target(os.getcwd(), key='.repo'):
        os.chdir(repo_path)
        if repo_path == os.getcwd():
            print('find repo in -->', repo_path)
            print(bash_shell('pwd'))
            print(bash_shell('repo forall -c git config core.fileMode false	--replace-all'))

        else:
            print('error in chdir 2 {}'.format(repo_path))
        if os.getcwd() != cwd:
            os.chdir(cwd)
        if os.getcwd() != cwd:
            print('change 2 cwd FAIL !!!  {}'.format(cwd))

    # this for git
    for git_path in find_target(os.getcwd(), key='.git'):
        os.chdir(git_path)
        if git_path == os.getcwd():
            print('find git in -->', git_path)
            print(bash_shell('pwd'))
            print(bash_shell('git config --global core.filemode false'))
        else:
            print('error in chdir 2 {}'.format(git_path))
        if os.getcwd() != cwd:
            os.chdir(cwd)
        if os.getcwd() != cwd:
            print('change 2 cwd FAIL !!!  {}'.format(cwd))

    et = time.time()
    print('\n\n    #### execute finished in {:.3f} seconds ####'.format(et - st))
    print('\n')
    # test for bash_command
    # print(bash_shell('git init'))
    # print(bash_shell('ls -al'))

于是，执行之后的输出如下：

bash_command = pwd
/Users/cat/Desktop/testGit/a6
bash_command = pwd
/Users/cat/Desktop/testGit/a6/frameworks/base
bash_command = pwd
/Users/cat/Desktop/testGit/a6/packages/apps/Email
bash_command = pwd
/Users/cat/Desktop/testGit/a6/packages/apps/Music
bash_command = pwd
/Users/cat/Desktop/testGit/a6/packages/apps/Settings
bash_command = pwd
/Users/cat/Desktop/testGit/a6/vender/customer
spend time : 0.096 seconds
end  ####################  end

Process finished with exit code 0

通过输出可以看到，所有的.repo以及.git目录所在目录是已经找出来了。然后执行bash_commad(command)即可在仓库目录执行git / repo命令了。
