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.

SCREENDIR Environment variable overriding the default directory for session sockets (default: /tmp/screens/S-username). KEY BINDINGS All commands are prefixed with Ctrl+a (command character): Ctrl+a c : Create new window Ctrl+a n/p : Next/previous window Ctrl+a " : List windows Ctrl+a 0-9 : Switch to window number Ctrl+a d : Detach from session Ctrl+a k : Kill current window Ctrl+a S : Split horizontally Ctrl+a \| : Split vertically Ctrl+a Tab : Switch between regions Ctrl+a X : Close current region Ctrl+a [ : Enter copy/scrollback mode Ctrl+a ] : Paste Ctrl+a ? : Show key bindings CAVEATS Screen's default configuration may conflict with some terminal features. Customize via ~/.screenrc . The command prefix Ctrl+a conflicts with readline's beginning-of-line. Remap with escape in .screenrc if needed. Nested screen sessions require pressing the prefix twice ( Ctrl+a a ) to send commands to the inner session. For modern alternatives with more features, consider tmux .

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. ## [PARAMETERS](https://linuxcommandlibrary.com/man/screen#parameters) \-S name > Create session with specified name \-r \[name\] > Reattach to a detached session \-R > Reattach if possible, otherwise start new session \-d > Detach a running session \-D > Detach and logout \-ls, \-list > List all sessions \-x > Attach to a session that is already attached (multi-display) \-dm > Start in detached mode (for scripts) \-X command > Send command to a running session \-L > Enable logging \-h lines > Set scrollback buffer size ## [CONFIGURATION](https://linuxcommandlibrary.com/man/screen#configuration) ~/.screenrc > Per-user configuration file for setting default options, key bindings, startup windows, and visual settings. /etc/screenrc > System-wide configuration file applied to all users before the per-user file. SCREENDIR > Environment variable overriding the default directory for session sockets (default: /tmp/screens/S-username). ## [KEY BINDINGS](https://linuxcommandlibrary.com/man/screen#key-bindings) All commands are prefixed with Ctrl+a (command character):Ctrl+a c: Create new windowCtrl+a n/p: Next/previous windowCtrl+a ": List windowsCtrl+a 0-9: Switch to window numberCtrl+a d: Detach from sessionCtrl+a k: Kill current windowCtrl+a S: Split horizontallyCtrl+a \\|: Split verticallyCtrl+a Tab: Switch between regionsCtrl+a X: Close current regionCtrl+a \[: Enter copy/scrollback modeCtrl+a \]: PasteCtrl+a ?: Show key bindings ## [CAVEATS](https://linuxcommandlibrary.com/man/screen#caveats) Screen's default configuration may conflict with some terminal features. Customize via ~/.screenrc.The command prefix Ctrl+a conflicts with readline's beginning-of-line. Remap with escape in .screenrc if needed.Nested screen sessions require pressing the prefix twice (Ctrl+a a) to send commands to the inner session.For modern alternatives with more features, consider tmux. ## [HISTORY](https://linuxcommandlibrary.com/man/screen#history) Screen was originally written by Oliver Laumann in 1987 and has been maintained by the GNU project. It was one of the first terminal multiplexers and established the paradigm that tmux and others follow. ## [SEE ALSO](https://linuxcommandlibrary.com/man/screen#see-also)
