有此git仓库的相关信息，初始化后要设置当前工作的用户名等相关信息，否则 使用全局设置 # git status #查看当前工作目录和暂存区的状态 On branch master No commits yet nothing to commit (create/copy files and use "git add" to track) # echo 'print("hello #提交当前工作目录的所有文件到暂存区（add为暂存操 作），命令最后有一个点. # git status #再次查看状态 On branch master No commits yet Changes to be commi�ed: (use "git rm --cached ..." to unstage) #查看未暂存的修改，在工作目录增删改文件后，未add的 # git diff --cached #查看未提交的暂存 ★分支操作 分支（branch）的本质其实就是一个提交对象（commit），HEAD是一个指针， 它默认指向master分支，切换分支时就是让HEAD指向不同的分支。每次有新的 提交时，HEAD都会自动指向最新的提交。
