git学习心得

   git是一款十分有用的版本控制软件，程序员必备。

http://www.liaoxuefeng.com/wiki/0013739516305929606dd18361248578c67b8067c8c017b000/0013743256916071d599b3aed534aaab22a0db6c4e07fd0000

1.生成key 

 ssh-keygen -t rsa 

将生成的位于.ssh下的pub文件cat后，复制到git的ssh key当中。

2.在.ssh目录下2新建config，加入port XXXX (端口)

3.修改config权限 chmod 600

4.git pull origin master 该步骤要位于当前工作空间之下

当前工作空间：

F:\Program Files\Git\guoxungit\hearthdap-front

//取消更改 回滚到上次状态

1.git reset --hard

2.git reset --hard head^^ //回滚到上上次 ……head~1//回滚到上一次版本

一.提交代码操作流程：

1.查看当前本地分支 git branch


2.查看网络分支 git branch -a


3.添加本地分支 git branch guoxun


4.切换到本地分支 git checkout guoxun


5.git status 查看当前文件状态


6.文件的三种状态 只有暂存区域的文件（即：文件状态为“Changes to be committed”）才会被提交
http://phplaber.iteye.com/blog/1699926
除了之前的“Changes to be committed”状态，现在又多了一条“Changes not staged for commit”状态，表明文件已经修改，但是还没有放入暂存区域，也就是没生成快照。如果现在进行commit操作，只是将修改之前的文件快照提交到了git目录，一定记住：只有暂存区域的文件（即：文件状态为“Changes to be committed”）才会被提交。正如提示，通过“git add README.txt”命令将已修改文件更新到暂存区域中，如果想撤销修改，可以使用“git checkout -- README.txt”命令


7.git add application/ 将以application开头的文件设为Changes to be committed状态


8.git reset HEAD .idea 将以.idea开头的文件从change to be committed状态回退到前一个状态


9.git log 查看近期修改日志


10.git commit -m "add index of help" 提交


11.git push origin guoxun 把修改提交到分支上

二.解决远端冲突问题：

1.这里有个暴力解法 在保证你本地已经是你当前所需的结果，那么可以直接删除远端。

http://git.qyidea.com/hui.chen/hearthdap-front/branches

在这个网站上直接删除了远端分支，解决了问题· 也可以用 git push origin :guoxun 来删除远端 本质上，不是删除，是覆盖远端。
