git 使用学习

• git add :stage the file

• git rm --cached : unstage the file

• git status :查看当前状态

• vim readtest: new file
  git status 会发现 untracked files : #r readtest

git add readtest : add readtest into the staged area and track it.

readtest会出现在 changes to be committed下 说明已readtest已进入暂存状态 staged

• vim README.md 做出修改后, :wq 保存退出

• git status : changes not staged for commit

  • git add README.md : to update what has been changed
  • git checkout -- : to discard the changes in working directory

$ git mv README.txt README
$ git status
On branch master
Changes to be committed:
(use "git reset HEAD ..." to unstage)

    renamed:    README.txt -> README

其实 git mv运行了三条命令
$ mv README.txt README
$ git rm README.txt
$ git add README
