Git学习笔记-2

一、修改文件

将文件内容：

This is first sentence.
This is second sentence.

 修改为：

This is my first sentence.
This is my second sentence.

 二、查看当前状态

$ git status

 提示一下内容：

On branch master
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:   readme.txt

no changes added to commit (use "git add" and/or "git commit -a")

提示内容告诉我们，文件已经被修改了，但是不可以看到具体修改内容。

 三、查看具体修改内容

$ git diff readme.txt

 提示一下内容：

diff --git a/readme.txt b/readme.txt
index 78762af..6991a86 100644
--- a/readme.txt
+++ b/readme.txt
@@ -1,2 +1,2 @@
-This is first sentence.
