1.使用git status查看版本库的状态
$ git status
On branch master
nothing to commit, working directory clean
Git告诉我们当前没有需要提交的修改，而且，工作目录是干净（working directory clean）的。
2.现在去修改readme.txt的内容
原本内容为：
Git is a version control system.
Git is free software.
修改后：
Git is distributed a version control system.
Git is free software.
3.git status查询版本库的状态
$ git status
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")
[email protected] MINGW64 /e/learngit (master)
看到提示readme.txt是modified，但是没有准备提交修改
4.git diff readme.txt 查看readme.txt修改前后的差别
[email protected] MINGW64 /e/learngit (master)
$ git diff readme.txt
diff --git a/readme.txt b/readme.txt
index d8036c1..487c372 100644
--- a/readme.txt
+++ b/readme.txt
