screen 命令

常用示例

说明

screen is a terminal multiplexer that allows running multiple terminal sessions within a single window. Sessions can be detached and reattached, making them persistent across disconnections—essential for remote work and long-running processes. Each screen session can contain multiple windows, each running its own shell or program. Windows can be split into regions to view multiple windows simultaneously. Sessions persist even when you disconnect, whether intentionally or due to network issues. This makes screen invaluable for running processes on remote servers that must survive connection drops. Copy mode allows scrolling through terminal history and copying text between windows or to the clipboard.
