查看版本

git –version

生成密钥

ssh-keygen -t rsa -C “desc key”

ssh-add ~/.ssh/id_rsa

Could not open a connection to your authentication agent.

eval

ssh-agent

ssh-add ~/.ssh/id_rsa

cat ~/.ssh/id_rsa.pub

注意：每台电脑每个用户生成的key不一样，-C后面的参数尽量描述清楚生成的key属于哪台电脑哪个用户

配置全局环境变量

git config –global user.name “xxx”

全局变量用户名

git config –global user.email “xxx@xxx.com”

全局变量用户邮箱

git config –global core.autocrlf false

Carriage-Return Line-Feed 回车换行设置

git config –global gui.encoding utf-8

字符集

查看配置参数

git config –list

常规使用

git init

初始化版本库

git status

查看状态

git add .

添加文件

git commit -am ‘commit message’

提交

git remote add origin git@git.oschina.net:xxx/xxx.git

添加远程分支

git branch

查看分支

git branch -r –>查看远程分支

git push -u origin master

提交代码到远程master分支

hint: See the 'Note about fast-forwards' in 'git push --help' for details.

提交代码前先pull一下代码

或者强制提交，覆盖

git push -u -f origin master

git pull

更新代码

git branch –set-upstream-to=origin/master master

本地分支与远程分支关联

http://higoge.github.io/2015/07/06/git-remote03/

git checkout -b v1.0 origin/master

建立分支

切换远程分支

git remote set-url origin url

git remote rm origin

git remote add origin git@github.com:sheng/demo.git

如果你的项目有加入版本控制，那可以到项目根目录下，查看隐藏文件夹， 发现.git文件夹，找到其中的config文件，就可以修改其中的git remote origin地址了

git config remote.origin.push refs/heads/*:refs/for/*

当执行push命令时，将会推送到refs/for/当前head所在的分支上
