“砰”的意思是什么？或“！”在git命令之前？ [英] What is the meaning of the "bang" or "!" before the git command?

问题描述

正如你从这段摘录中看到的那样，有一个！在git命令之前。有什么意义？

  [别名] 
 commitx =！git add。 &安培;&安培; git commit

我了解别名和命令本身在做什么，但不是！之前的git命令。

解决方案

！表示运行以下作为shell的命令，所以在这种情况下，别名 git commitx 扩展为相当于运行 git add。 &安培;&安培; git commit （这是一个糟糕的主意）

As you can see from this excerpt, there is a "!" before the git command. What's the point?

[alias]
commitx = !git add . && git commit

- https://stackoverflow.com/a/8956546/1354543

I understand aliases and what the command itself is doing, but not the point of the "!" before the git command.

解决方案

The ! means "run the following as commands to the shell", so in this case the alias git commitx expands to the equivalent of running git add . && git commit (which is a terrible terrible idea)
