Git与Github使用之--常用本地命令介绍

查看当前仓库状态

运行git status 命令可以查看结果：

MacBook-Pro-2% git status
On branch master
nothing to commit, working tree clean

git status 可以让我们时刻掌握仓库当前状态，上面的命令告诉我们在上次提交后没有被修改的文件
，那么我们修改后再试试看：

MacBook-Pro-2% 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")
MacBook-Pro-2% 

这里没有显示修改的内容，如果能看什么被修改了但是没提交那是极好的。所以我们需要git diff 这个命令来看看：

MacBook-Pro-2% git diff
diff --git a/readme.txt b/readme.txt
index 884b2bc..0b138d6 100644
--- a/readme.txt
+++ b/readme.txt
@@ -1,2 +1,3 @@
 this is the readme file for myweb
 i can learn web by practice!
+we can show our reaserch result though web tech!

我们在这里可以看到readme.txt文件被修改了，并且知道了修改了什么内容，接下来就可以先用git add 再用git commit 来提交修改了：

MacBook-Pro-2% git add readme.txt
MacBook-Pro-2% git commit -a
Aborting commit due to empty commit message.
MacBook-Pro-2% git commit -m "add distributed"
[master 130362a] add distributed
 Committer: Chenjun Xiong <ChadwinSean@MacBook-Pro-2.local>
