Git 暂存修改文件 取消暂存

序：Git 已经用了不少年了，起步用的SourceTree ，所以对命令不是很熟悉，最近换了台电脑，索性不按sourceTree了，总结下命令行。
Git 最经常使用的操作就是：  
工作空间----已修改文件----暂存----提交到本地git---push到远程git
这是一条我们没有特殊需求，没有出现错误和冲突的流程。
1.查看工作空间已修改的文件
git status
example:
zhangyudeiMac:server-psi zhangyu$ git statusOn branch masterYour branch is up-to-date with 'origin/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:   web/Application/Common/Conf/config.php modified:   web/Application/Mobile/Controller/PurchaseDetailController.class.php modified:   web/Application/Mobile/View/Purchase/purchaseList.html modified:   web/Application/Mobile/View/PurchaseDetail/purchaseDetail.html modified:   web/Public/Scripts/Mobile/PurchaseDetail/PurchaseDetail.js
no changes added to commit (use "git add" and/or "git commit -a")

2.上个命令我们就可以看出所有修改过的文件，让后我们应该暂存这些文件。
  * 单文件暂存
        git add  "Path(文件路径)" example:
zhangyudeiMac:server-psi zhangyu$ git  add web/Application/Mobile/Controller/PurchaseDetailController.class.php

  * 暂存全部已修改文件
git add  -u

example:
zhangyudeiMac:server-psi zhangyu$ git add -u zhangyudeiMac:server-psi zhangyu$ git status On branch master Your branch is up-to-date with 'origin/master'.
Changes to be committed:   (use "git reset HEAD <file>..." to unstage)
modified:   web/Application/Common/Conf/config.php modified:   web/Application/Mobile/Controller/PurchaseDetailController.class.php modified:   web/Application/Mobile/View/Purchase/purchaseList.html modified:   web/Application/Mobile/View/PurchaseDetail/purchaseDetail.html modified:   web/Public/Scripts/Mobile/PurchaseDetail/PurchaseDetail.js

3.暂存的文件都是要为提交做准备的文件，如果我们有些文件已经暂存了，我们想还原到非暂存怎么办。
git reset  "Path(文件路径)"
example: zhangyudeiMac:server-psi zhangyu$ git reset web/Application/Common/Conf/config.php Unstaged changes after reset: M web/Application/Common/Conf/config.php zhangyudeiMac:server-psi zhangyu$ git status On branch master Your branch is up-to-date with 'origin/master'.
Changes to be committed:   (use "git reset HEAD <file>..." to unstage)
modified:   web/Application/Mobile/Controller/PurchaseDetailController.class.php modified:   web/Application/Mobile/View/Purchase/purchaseList.html modified:   web/Application/Mobile/View/PurchaseDetail/purchaseDetail.html modified:   web/Public/Scripts/Mobile/PurchaseDetail/PurchaseDetail.js
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:   web/Application/Common/Conf/config.php
4.最后一步是提交到本地git和push到远程git，估计都会还是贴上吧。
zhangyudeiMac:server-psi zhangyu$ git commit -m "bangdingwuliuadd"
zhangyudeiMac:server-psi zhangyu$ git push
