Linux下screen的简单介绍

官网上的英文介绍:
Screen is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. Each virtual terminal provides the functions of the DEC VT100 terminal and, in addition, several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022 standards (e.g., insert/delete line and support for multiple character sets). There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows the user to move text regions between windows. When screen is called, it creates a single window with a shell in it (or the specified command) and then gets out of your way so that you can use the program as you normally would. Then, at any time, you can create new (full-screen) windows with other programs in them (including more shells), kill the current window, view a list of the active windows, turn output logging on and off, copy text between windows, view the scrollback history, switch between windows, etc. All windows run their programs completely independent of each other. Programs continue to run when their window is currently not visible and even when the whole screen session is detached from the users terminal.
ubuntu下的安装命令
sudo apt-get install screen
screen常用命令
screen -S <name> 创建并打开一个叫name的screen会话, 打开的界面如下所示
screen -ls 查看当前有哪些screen会话在运行, 有Attached和Detached两个, ctrl+a+d就是保存会话退出, Detached状态, 之后可以恢复
screen -r <name> 连接到已有的screen会话, 例如使用screen -r test 重新连接到已有的会话中
