推荐答案

棒棒（ !! ）命令的快捷方式的重复previous命令你在终端上输入。当你忘了，你需要管理员权限做出了一定的作用这个命令非常有用，并让您具有超级用户权限重复只需键入

The bang bang (!!) command is a shortcut to repeat the previous command you entered in your terminal. This command is very useful when you forget that you need admin rights to make a certain action, and lets you repeat it with super-user rights just by typing

sudo !!

而不是键入向上箭头，滚动到行的开头，加入须藤并按下回车键（想象一下，通过这些的 loooong 的<滚动code> apt-get的命令）。因此，许多秒获得！的耶！的

instead of typing arrow-up, scrolling to the beginning of the line, adding sudo and hitting enter (imagine scrolling through those loooong apt-get commands). So many seconds gained! Yay!
