此外，我还完成了针对个人$sudo git --bare init /var/repos/git/repo00001执行的以下命令，
UNIX users我应该在哪个目录下创建$ git config --global user.email "MyfullName@mindtree.com"
$ git config --global user.name "Anand Sadasivam"
，我在签入文件时遇到问题。应该为目录git repsitories设置权限，用户，组，我将在其下创建git存储库。目前它在root权限下完成。在使用/var/repos/git
UNIX user独占创建单独的git或任何特定的步骤或git命令，以便先创建用户
我观察到git init --bare在init下创建了一些基本结构。但当我git repository时，我的存储库是空的。
由于我使用了git clone，我可以看到如下创建的文件夹结构，

使用--bare init --shared选项创建的存储库具有rw组用户访问权限。

因此，我已将需要使用git存储库的所有用户添加到组git，因为您可以看到git:git已创建存储库，而组git已rwx对于将要维护修订的大多数文件夹。
我添加了＆amp;验证用户是否已添加到群组， - git
