在Git中创建远程repo的不同命令

Git（VCS工具）中的这些命令之间有什么区别：

请您向我解释一下好吗？

从手册页：

   --shared[=(false|true|umask|group|all|world|everybody|0xxx)]
       Specify that the git repository is to be shared amongst several users. This allows users belonging to the same group to push into that repository. When
       specified, the config variable "core.sharedRepository" is set so that files and directories under $GIT_DIR are created with the requested permissions. When
       not specified, git will use permissions reported by umask(2).

你到底在想什么？

我在终端中使用“mangit”命令，但还没有看到这样的行！您从哪里获得它们的？或者，

git init--help

（您可以将

--help

与任何git命令一起使用）

   --shared[=(false|true|umask|group|all|world|everybody|0xxx)]
       Specify that the git repository is to be shared amongst several users. This allows users belonging to the same group to push into that repository. When
       specified, the config variable "core.sharedRepository" is set so that files and directories under $GIT_DIR are created with the requested permissions. When
       not specified, git will use permissions reported by umask(2).
