git's Introduction

git for mac

what we need to do is just install a tool named Command Line Tools

//open the terminal,and type
xcode-select --install enter
//test 
gcc -v
//if it shows below message, then it's installed.
xcode-select: note: install requested for command line developer tools

ssh key

$ ssh-keygen -t rsa -C "[email protected]"
ssh -T [email protected]
ssh -T [email protected]

need pwd to access

git add .
git status
git commit -m ''
git push //if it fails to push, we need to use git pull adn add some message for it
enter your uname
enter your pwd
...
Ok

config

add id_rsa.pub into vps 首先配置自己的身份，这样在提交代码的时候就能知道是谁提交的

输入git config --global user.name "名字"
git config --global user.email "邮箱地址"
输入git init就可以创建啦~
然后使用ls -al查询代码仓库，如果想删除这个仓库，直接从目录下删除这个文件夹就可以了
仓库建立完成之后就可以提交本地代码了，这里只需要用到两个命令，add添加和commit提交
add .是提交所有
add +文件名是提交单个文件
git commit -m "First commit"是提交这里要在-m参数后面加上提交参数，很重要哟，不然会被认为不合法不能提交.
