前言：

最近為了跑多個shell來上傳映象，所以接觸了screen，但是一般介紹的screen教程比較少，不能提供比較實用的快捷方式，這裡搜尋到了就分享下：

正文：

screen is a much under utilised program, which provides the following functionality:

• Remote terminal session management (detaching or sharing terminal sessions)
• unlimited windows (unlike the hardcoded number of Linux virtual consoles)
• scrollback buffer (not limited to video memory like Linux virtual consoles)
• copy/paste between windows
• notification of either activity or inactivity in a window
  split terminal (horizontally and vertically) into multiple regions
• locking other users out of terminal

  See also the tmux alternative
  See also the byobu screen config manager.
  See also the reptyr as another way to reattach programs to a terminal.
  Note for nested screen sessions, use “Ctrl+a a” to send commands to the inner screen,
  and the standard “Ctrl+a” to send commands to the outer screen.
