初步学习Git——分布式版本管理系统(2)

如果我们对readme.text做以下改动

Git is a distributed version control system.
Git is free software.

会发生什么呢，我们可以通过这两个命令来查看他们的变化

staus命令

Administrator@PC-20140823TXAB MINGW64 /c/learngit (master)
$ 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")

Administrator@PC-20140823TXAB MINGW64 /c/learngit (master)
$

satus命令可以让我们时刻掌握仓库当前的状态，上面的命令告诉我们，readme.txt被修改过了，但还没有准备提交的修改。

git diff命令

git diff顾名思义就是查看difference

$ git diff
diff --git a/readme.txt b/readme.txt
index d8036c1..ee2c1ea 100644
--- a/readme.txt
+++ b/readme.txt
