1、環境的構建：
使用Mac系統自帶的Git進行版本管理存在，Git是系統的Xcode集成的
查看版本的命令：
1 $ git --version 2 git version 2.14.3 (Apple Git-98)
查看git的安裝目錄：
1 $ which git 2 /usr/bin/git
2、常用命令
1 #使用git命令初始化文件夾,即創建git本地倉庫 2 $ git init 3 Initialized empty Git repository in /Users/Mac/Desktop/myapp/.git/ 4 #配置全局變量 5 $ git config --global user.name "***" 6 $ git config --global user.email '****@qq.com' 7 #將index.jsp 添加到git倉庫中 8 $ git add index.jsp 9 #獲取git本地倉庫狀態 10 $ git status 11 #使用通配符添加文件到本地倉庫,此命令表示將需要添加的本地倉庫的所有html文件添加到本地倉庫 12 $ git add *.html 13 #此命令表示將需要添加的本地倉庫的所有文件添加到本地倉庫 14 $ git add . 15 #從git本地倉庫中移除index.jsp文件 16 $ git rm --cached index.jsp 17 #將已添加到本地倉庫的文件全部提交,當輸入此命令時,會切換到一個編輯頁面,此時需輸入此次提交的備注信息,保存退出即可 18 $ git commit 19 #此命令中參數'-m'后添加備注信息 20 $ git commit -m 'another change' 21 #創建.gitignore文件,該文件的作用是忽略文件中的指定文件,即不用添加提交的文件 22 $ touch .gitignore 23 #演示創建分支的方法,在分支下修改文件,除非合並,否則不會實質性修改主線的內容 24 $ git branch login 25 #切換到master角色下 26 $ git checkout master 27 #在master角色下合並分支命令 28 $ git merge login 29 #以下演示同步到GitHub上 30 #查看是否已有遠程連接 31 $ git remote 32 #創建遠程連接命令,"***"此內容需要在GitHub指定查看上復制 33 $ git remote add origin git@github.com:****/***.git 34 #將本地倉庫中的文件推送到GitHub倉庫上 35 $ git push -u origin master 36 #由於之前已建立連接,故此時只需直接即可push 37 $ git push 38 #從GitHub倉庫中克隆項目到本地倉庫 39 $ git clone **@github.com:***/homework.git
