![]() The above example would start the emacs editor (editing prog.c) and switch to its window. This will not run another copy of screen, but will instead supply the command name and its arguments to the window manager (specified in the $STY environment variable) who will use it to create the new window. ![]() In addition, new windows can be created by running a command like:įrom a shell prompt within a previously created window. ![]() screenrc file or at the C-a : command line) and then using it just like the C-a c command. Similarly, you can create a new window with a custom command in it by first binding the command to a keystroke (in your. This creates a new window running a shell and switches to that window immediately, regardless of the state of the process running in the current window. The standard way to create a new window is to type C-a c. Screen will also print out control characters in caret notation. ![]() Please use the caret notation (^A instead of C-a) as arguments to e.g. Screen does not understand the prefix C- to mean control, although this notation is used in this manual for readability. The command character and all the key bindings can be fully customized to be anything you like, though they are always two characters in length. By default, each command begins with a control-a (abbreviated C-a from now on), and is followed by one other keystroke. The only exception to this is the one keystroke that is used to initiate a command to the window manager. screenrc command).Įverything you type is sent to the program running in the current window. Screen runs them as sub-shells, unless told otherwise (See shell. Shells usually distinguish between running as login-shell or sub-shell. If this window was in the foreground, the display switches to the previous window if none are left, screen exits. When a program terminates, screen (per default) kills the window that contained it. Programs continue to run when their window is currently not visible and even when the whole screen session is detached from the user's terminal. All windows run their programs completely independent of each other. Then, at any time, you can create new (full-screen) windows with other programs in them (including more shells), kill existing windows, view a list of windows, turn output logging on and off, copy-and-paste text between windows, view the scrollback history, switch between windows in whatever manner you wish, etc. 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. There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows moving text regions between windows. insert/delete line and support for multiple character sets). Each virtual terminal provides the functions of a DEC VT100 terminal and, in addition, several control functions from the ISO 6429 (ECMA 48, ANSI X3.64) and ISO 2022 standards (e.g. Screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells).
