git diff HEAD与git diff --staged有什么区别? [英] What is the difference between git diff HEAD vs. git diff --staged?

问题描述

git diff HEAD和git diff --staged有什么区别?我都尝试过，但是都给出相同的输出.

What is the difference between git diff HEAD and git diff --staged? I tried both but both give the same output.

推荐答案

假设此输出为git status:

$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   new file:   y
#
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#   modified:   x
#

如您所见，已经修改了一个文件，但未准备好提交该文件，并且添加了一个准备好提交的新文件.

As you see, there is one file modified but not staged for commit, and a new file added that is ready to be committed.

git diff --staged仅显示对暂存"区域中文件的更改.

git diff --staged will only show changes to files in the "staged" area.

git diff HEAD将显示对跟踪文件的所有更改.如果您已准备好所有更改以进行提交，那么这两个命令将输出相同的内容.

git diff HEAD will show all changes to tracked files. If you have all changes staged for commit, then both commands will output the same.
