了解文件上的git diff [英] Understanding git diff on files

问题描述

git diff 的含义是什么？

  diff --git a / README.md b / README.md 
 index 24aa464..49c20f4 100644 
 --- a / README.md 
 +++ b / README.md 
 @@ -1,3 +1,2 @@ 
 LINE1 
 -LINE2 
 LINE3 
  

我想我明白 - 新的LINE2意味着工作区中的版本没有处于暂存状态的LINE2，但是 @@ - 1,3 +1,2 @@ 意思是

解决方案

差异与该大块有关，意思是/ README.md中的第1行至第3行以及b / README.md中的第1行至第2行。

What does the folowing output of git diff mean?

diff --git a/README.md b/README.md
index 24aa464..49c20f4 100644
--- a/README.md
+++ b/README.md
@@ -1,3 +1,2 @@
 LINE1
-LINE2
 LINE3

I think I understand that the "-" new LINE2 means that the version on have in workspace does not have the LINE2 that is in staging, but what does @@ -1,3 +1,2 @@ mean??

解决方案

It is the line ranges that the diff is concerned with for that hunk, meaning lines 1 to 3 in a/README.md and lines 1 to 2 in b/README.md.
