因?yàn)镸ac下已經(jīng)自帶了git，所以我們跳過(guò)此步驟，如果你是Linux的其他系統(tǒng)，可以使用一下代碼進(jìn)行安裝：
sudo apt-get install git-core //安裝Git
用戶配置
git config --global user.name "Your Name" //配置用戶名稱(chēng)
git config --global user.email "Your Email" //配置用戶郵箱
git config --list //查看配置信息
第一次初始化git版本庫(kù)
開(kāi)始一個(gè)新的項(xiàng)目，初始化新的代碼倉(cāng)庫(kù)，要對(duì)現(xiàn)有的某個(gè)項(xiàng)目開(kāi)始用 Git 管理，只需到此項(xiàng)目所在的目錄，執(zhí)行：
git init
會(huì)在當(dāng)前目錄下生成一個(gè).git目錄，包含了所有g(shù)it需要的數(shù)據(jù)和資源
進(jìn)行g(shù)it添加，提交，推送操作
touch README //創(chuàng)建README
git add . //添加左右新增或者改動(dòng)過(guò)的文件
git commit -a -m "添加README" //提交變更到本地版本庫(kù)
git push origin <branch name> //推送本地版本庫(kù)到遠(yuǎn)程倉(cāng)庫(kù)
git克隆遠(yuǎn)程倉(cāng)庫(kù)
//Git本身的源代碼你既可以用 git:// 協(xié)議來(lái)訪問(wèn)：
git clone git@git.jianshu.net:******/****.git
//也可以通過(guò)http 協(xié)議來(lái)訪問(wèn):
git clone https://git.jianshu.net/******/****.git
//自定義目錄名稱(chēng)，如果不自定義，默認(rèn)為遠(yuǎn)程倉(cāng)庫(kù)的項(xiàng)目目錄名稱(chēng)
git clone https://git.jianshu.net/******/****.git mygrit
Git分支操作
查看分支 git branch
創(chuàng)建分支 git branch <branch name>
切換分支 git checkout branch
合并分支 git merge <branch name> //合并某分支到當(dāng)前分支
刪除分支git branch -d <branch name>
mac git --help
