linux scripted git pull error: cannot open .git/FETCH_HEAD: Permission Denied
提问by idonaldson
Need a little help scripting a git pull.
需要一些帮助来编写 git pull 脚本。
We have an intranet server that we are trying to script a git pull to, and I'm running into a permission issue.
我们有一个内部网服务器，我们正在尝试编写 git pull 脚本，但我遇到了权限问题。
error: cannot open .git/FETCH_HEAD: Permission denied
We've setup a user account on the server, cloned the project to that account, chmod 775 -R the directory tree, and setup the ssh key so there is no password prompt.
我们已经在服务器上设置了一个用户帐户，将项目克隆到该帐户，chmod 775 -R 目录树，并设置了 ssh 密钥，因此没有密码提示。
The script looks like so:
脚本如下所示：
#! /bin/bash
sudo /bin/su - gitrepouser
cd /some/directory/for/git && git pull
When I run the script as another user, it runs the sudo command, and stops, after typing exit and I get the error message.
当我以另一个用户身份运行脚本时，它会运行 sudo 命令，然后在输入 exit 后停止，我收到错误消息。
This script will be called by our batch process on a 10 minute interval, pulling any production changes down from BitBucket.
该脚本将由我们的批处理以 10 分钟的间隔调用，从 BitBucket 中提取任何生产更改。
Thoughts?

You probably need to make the user the owner of the folder
您可能需要使用户成为文件夹的所有者
chown gitrepouser -Rf /some/directory/for/git

The problem is that sustarts its own shell; the second command isn't executed in that shell, but in the original one. You can demonstrate this by running the following script:
问题是su启动了自己的shell；第二个命令不是在那个 shell 中执行，而是在原始命令中执行。您可以通过运行以下脚本来演示这一点：
#!/bin/bash
su
whoami
Unless you're already root when you run it, it won't output root.
除非你在运行它时已经是 root，否则它不会输出root.
The solution is to use su's -cswitch:
解决方案是使用su的-c开关：
sudo /bin/su -c "cd /some/directory/for/git && git pull" - gitrepouser
