Installation 安装

常用命令

Getting in ——————— start a new screen session: screen attach to a running session: screen -r the “ultimate attach”: screen -dRR (Attaches to a screen session. If the session is attached elsewhere, detaches that other display. If no session exists, creates one. If multiple sessions exist, uses the first one.)

Escape key

All screen commands are prefixed by an escape key, by default C-a (that’s Control-a, sometimes written ^A). To send a literal C-a to the programs in screen, use C-a a.
