Question

每当我在git中使用子模块时，发现自己在做

git submodule init
git submodule update

每次基本执行这些命令时，两个命令中的逻辑是什么？

Answer 1

不确定分离，但一个简单的解决方法是使用别名。

alias gitrox="git submodule init && git submodule update"

Answer 2

git submodule init初始化机器，而git submodule update为子模块引入新的更改。如果您要添加子模块，则无需更新任何内容，因此您只需运行git submodule init即可初始化回购。（它会创建一个.gitmodules文件，以及.git/中用于跟踪子模块的一些内容。）

Answer 3

他们确实有办法在一次通话中完成：

为什么没有git submodule init和git submodule更新一个命令？
