Each -virtual terminal provides the functions of the DEC VT100 terminal and, -in addition, several control functions from the ISO 6429 (ECMA 48, ANSI -X3.64) 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 user's terminal. - - When a program terminates, `screen' (per default) kills the window -that contained it. If this window was in the foreground, the display -switches to the previously displayed window; if none are left, `screen' -exits. - - Everything you type is sent to the program running in the current -window. The only exception to this is the one keystroke that is used to -initiate a command to the window manager. By default, each command -begins with a control-a (abbreviated `C-a' from now on), and is -followed by one other keystroke. The command character (*note Command -Character::) and all the key bindings (*note Key Binding::) can be fully -customized to be anything you like, though they are always two -characters in length. - - `Screen' does not understand the prefix `C-' to mean control. -Please use the caret notation (`^A' instead of `C-a') as arguments to -e.g. the `escape' command or the `-e' option. `Screen' will also print -out control characters in caret notation. - - The standard way to create a new window is to type `C-a c'. 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. Similarly, you can create a new window with a custom -command in it by first binding the command to a keystroke (in your -`.screenrc' file or at the `C-a :' command line) and then using it just -like the `C-a c' command. In addition, new windows can be created by -running a command like: - - screen emacs prog.c - -from a shell prompt within a previously created 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. The -above example would start the `emacs' editor (editing `prog.c') and -switch to its window. - - If `/etc/utmp' is writable by `screen', an appropriate record will -be written to this file for each window, and removed when the window is -closed. This is useful for working with `talk', `script', `shutdown', -`rsend', `sccs' and other similar programs that use the utmp file to -determine who you are. As long as `screen' is active on your terminal, -the terminal's own record is removed from the utmp file. *Note Login::. - - -File: screen.info, Node: Getting Started, Next: Invoking Screen, Prev: Overview, Up: Top - -Getting Started -*************** - - Before you begin to use `screen' you'll need to make sure you have -correctly selected your terminal type, just as you would for any other -termcap/terminfo program. (You can do this by using `tset', `qterm', -or just `set term=mytermtype', for example.) - - If you're impatient and want to get started without doing a lot more -reading, you should remember this one command: `C-a ?' (*note Key -Binding::). Typing these two characters will display a list of the -available `screen' commands and their bindings. Each keystroke is -discussed in the section on keystrokes (*note Default Key Bindings::). -Another section (*note Customization::) deals with the contents of your -`.screenrc'. - - If your terminal is a "true" auto-margin terminal (it doesn't allow -the last position on the screen to be updated without scrolling the -screen) consider using a version of your terminal's termcap that has -automatic margins turned _off_. This will ensure an accurate and -optimal update of the screen in all circumstances. Most terminals -nowadays have "magic" margins (automatic margins plus usable last -column). This is the VT100 style type and perfectly suited for -`screen'. If all you've got is a "true" auto-margin terminal `screen' -will be content to use it, but updating a character put into the last -position on the screen may not be possible until the screen scrolls or -the character is moved into a safe position in some other way. This -delay can be shortened by using a terminal with insert-character -capability. - - *Note Special Capabilities::, for more information about telling -`screen' what kind of terminal you have. - - -File: screen.info, Node: Invoking Screen, Next: Customization, Prev: Getting Started, Up: Top - -Invoking `Screen' -***************** - - Screen has the following command-line options: - -`-a' - Include _all_ capabilities (with some minor exceptions) in each - window's termcap, even if `screen' must redraw parts of the display - in order to implement a function. - -`-A' - Adapt the sizes of all windows to the size of the display. By - default, `screen' may try to restore its old window sizes when - attaching to resizable terminals (those with `WS' in their - descriptions, e.g. `suncmd' or some varieties of `xterm'). - -`-c FILE' - Use FILE as the user's configuration file instead of the default - of `$HOME/.screenrc'. - -`-d [PID.SESSIONNAME]' -`-D [PID.SESSIONNAME]' - Do not start `screen', but instead detach a `screen' session - running elsewhere (*note Detach::). `-d' has the same effect as - typing `C-a d' from the controlling terminal for the session. - `-D' is the equivalent to the power detach key. If no session can - be detached, this option is ignored. In combination with the - `-r'/`-R' option more powerful effects can be achieved: - - `-d -r' - Reattach a session and if necessary detach it first. - - `-d -R' - Reattach a session and if necessary detach or even create - it first. - - `-d -RR' - Reattach a session and if necessary detach or create it. Use - the first session if more than one session is available. - - `-D -r' - Reattach a session. If necessary detach and logout remotely - first. - - `-D -R' - Attach here and now. In detail this means: If a session is - running, then reattach. If necessary detach and logout - remotely first. If it was not running create it and notify - the user. This is the author's favorite. - - `-D -RR' - Attach here and now. Whatever that means, just do it. - - _Note_: It is a good idea to check the status of your sessions - with `screen -list' before using this option. - -`-e XY' - Set the command character to X, and the character generating a - literal command character (when typed after the command character) - to Y. The defaults are `C-a' and `a', which can be specified as - `-e^Aa'. When creating a `screen' session, this option sets the - default command character. In a multiuser session all users added - will start off with this command character. But when attaching to - an already running session, this option only changes the command - character of the attaching user. This option is equivalent to the - commands `defescape' or `escape' respectively. (*note Command - Character::). - -`-f' -`-fn' -`-fa' - Set flow-control to on, off, or automatic switching mode, - respectively. This option is equivalent to the `defflow' command - (*note Flow Control::). - -`-h NUM' - Set the history scrollback buffer to be NUM lines high. - Equivalent to the `defscrollback' command (*note Copy::). - -`-i' - Cause the interrupt key (usually `C-c') to interrupt the display - immediately when flow control is on. This option is equivalent to - the `interrupt' argument to the `defflow' command (*note Flow - Control::). Its use is discouraged. - -`-l' -`-ln' - Turn login mode on or off (for `/etc/utmp' updating). This option - is equivalent to the `deflogin' command (*note Login::). - -`-ls [MATCH]' -`-list [MATCH]' - Do not start `screen', but instead print a list of session - identification strings (usually of the form PID.TTY.HOST; *note - Session Name::). Sessions marked `detached' can be resumed with - `screen -r'. Those marked `attached' are running and have a - controlling terminal. If the session runs in multiuser mode, it - is marked `multi'. Sessions marked as `unreachable' either live - on a different host or are dead. An unreachable session is - considered dead, when its name matches either the name of the - local host, or the specified parameter, if any. See the `-r' flag - for a description how to construct matches. Sessions marked as - `dead' should be thoroughly checked and removed. Ask your system - administrator if you are not sure. Remove sessions with the - `-wipe' option. - -`-L' - Tell `screen' to turn on automatic output logging for the windows. - -`-m' - Tell `screen' to ignore the `$STY' environment variable. When - this option is used, a new session will always be created, - regardless of whether `screen' is being called from within another - `screen' session or not. This flag has a special meaning in - connection with the `-d' option: - `-d -m' - Start `screen' in _detached_ mode. This creates a new session - but doesn't attach to it. This is useful for system startup - scripts. - - `-D -m' - This also starts `screen' in _detached_ mode, but doesn't fork - a new process. The command exits if the session terminates. - -`-p NAME_OR_NUMBER' - Preselect a window. This is usefull when you want to reattach to a - specific windor or you want to send a command via the `-X' option - to a specific window. As with screen's select commant, `-' selects - the blank window. As a special case for reattach, `=' brings up - the windowlist on the blank window. - -`-q' - Suppress printing of error messages. In combination with `-ls' the - exit value is set as follows: 9 indicates a directory without - sessions. 10 indicates a directory with running but not attachable - sessions. 11 (or more) indicates 1 (or more) usable sessions. In - combination with `-r' the exit value is as follows: 10 indicates - that there is no session to resume. 12 (or more) indicates that - there are 2 (or more) sessions to resume and you should specify - which one to choose. In all other cases `-q' has no effect. - -`-r [PID.SESSIONNAME]' -`-r SESSIONOWNER/[PID.SESSIONNAME]' - Resume a detached `screen' session. No other options (except - combinations with `-d' or `-D') may be specified, though the - session name (*note Session Name::) may be needed to distinguish - between multiple detached `screen' sessions. The second form is - used to connect to another user's screen session which runs in - multiuser mode. This indicates that screen should look for - sessions in another user's directory. This requires setuid-root. - -`-R' - Resume the first appropriate detached `screen' session. If - successful, all other command-line options are ignored. If no - detached session exists, start a new session using the specified - options, just as if `-R' had not been specified. This option is - set by default if screen is run as a login-shell (actually screen - uses `-xRR' in that case). For combinations with the `-D'/`-d' - option see there. - -`-s PROGRAM' - Set the default shell to be PROGRAM. By default, `screen' uses - the value of the environment variable `$SHELL', or `/bin/sh' if it - is not defined. This option is equivalent to the `shell' command - (*note Shell::). - -`-S SESSIONNAME' - Set the name of the new session to SESSIONNAME. This option can - be used to specify a meaningful name for the session in place of - the default TTY.HOST suffix. This name identifies the session for - the `screen -list' and `screen -r' commands. This option is - equivalent to the `sessionname' command (*note Session Name::). - -`-t NAME' - Set the title (name) for the default shell or specified program. - This option is equivalent to the `shelltitle' command (*note - Shell::). - -`-U' - Run screen in UTF-8 mode. This option tells screen that your - terminal sends and understands UTF-8 encoded characters. It also - sets the default encoding for new windows to `utf8'. - -`-v' - Print the version number. - -`-wipe [MATCH]' - List available screens like `screen -ls', but remove destroyed - sessions instead of marking them as `dead'. An unreachable - session is considered dead, when its name matches either the name - of the local host, or the explicitly given parameter, if any. See - the `-r' flag for a description how to construct matches. - -`-x' - Attach to a session which is already attached elsewhere - (multi-display mode). - -`-X' - Send the specified command to a running screen session. You can use - the `-d' or `-r' option to tell screen to look only for attached - or detached screen sessions. Note that this command doesn't work - if the session is password protected. - - - -File: screen.info, Node: Customization, Next: Commands, Prev: Invoking Screen, Up: Top - -Customizing `Screen' -******************** - - You can modify the default settings for `screen' to fit your tastes -either through a personal `.screenrc' file which contains commands to -be executed at startup, or on the fly using the `colon' command. - -* Menu: - -* Startup Files:: The `.screenrc' file. -* Source:: Read commands from a file. -* Colon:: Entering customization commands interactively. - - -File: screen.info, Node: Startup Files, Next: Source, Up: Customization - -The `.screenrc' file -==================== - - When `screen' is invoked, it executes initialization commands from -the files `.screenrc' in the user's home directory and -`/usr/local/etc/screenrc'. These defaults can be overridden in the -following ways: For the global screenrc file `screen' searches for the -environment variable `$SYSSCREENRC' (this override feature may be -disabled at compile-time). The user specific screenrc file is searched -for in `$SCREENRC', then ``$HOME'/.screenrc'. The command line option -`-c' specifies which file to use (*note Invoking Screen::. Commands in -these files are used to set options, bind commands to keys, and to -automatically establish one or more windows at the beginning of your -`screen' session. Commands are listed one per line, with empty lines -being ignored. A command's arguments are separated by tabs or spaces, -and may be surrounded by single or double quotes. A `#' turns the rest -of the line into a comment, except in quotes. Unintelligible lines are -warned about and ignored. Commands may contain references to -environment variables. The syntax is the shell-like `$VAR' or -`${VAR}'. Note that this causes incompatibility with previous `screen' -versions, as now the '$'-character has to be protected with '\' if no -variable substitution is intended. A string in single-quotes is also -protected from variable substitution. - - Two configuration files are shipped as examples with your screen -distribution: `etc/screenrc' and `etc/etcscreenrc'. They contain a -number of useful examples for various commands. - - -File: screen.info, Node: Source, Next: Colon, Prev: Startup Files, Up: Customization - -Source -====== - - - Command: source file - (none) - Read and execute commands from file FILE. Source commands may be - nested to a maximum recursion level of ten. If FILE is not an - absolute path and screen is already processing a source - command, the parent directory of the running source command file - is used to search for the new command file before screen's - current directory. - - Note that termcap/terminfo/termcapinfo commands only work at - startup and reattach time, so they must be reached via the - default screenrc files to have an effect. - - -File: screen.info, Node: Colon, Prev: Source, Up: Customization - -Colon -===== - - Customization can also be done online, with this command: - - - Command: colon - (`C-a :') - Allows you to enter `.screenrc' command lines.

When a new window is created, the first available -number from the range 0...9 is assigned to it. The number of windows -is limited at compile-time by the MAXWIN configuration parameter. - -* Menu: - -* Chdir:: Change the working directory for new windows. -* Screen Command:: Create a new window. -* Setenv:: Set environment variables for new windows. -* Shell:: Parameters for shell windows. -* Term:: Set the terminal type for new windows. -* Window Types:: Creating different types of windows. - - -File: screen.info, Node: Chdir, Next: Screen Command, Up: New Window - -Chdir -===== - - - Command: chdir [directory] - (none) - Change the current directory of `screen' to the specified directory - or, if called without an argument, to your home directory (the - value of the environment variable `$HOME'). All windows that are - created by means of the `screen' command from within `.screenrc' - or by means of `C-a : screen ...' or `C-a c' use this as their - default directory. Without a `chdir' command, this would be the - directory from which `screen' was invoked. Hardcopy and log files - are always written to the _window's_ default directory, _not_ the - current directory of the process running in the window. You can - use this command multiple times in your `.screenrc' to start - various windows in different default directories, but the last - `chdir' value will affect all the windows you create interactively. - - -File: screen.info, Node: Screen Command, Next: Setenv, Prev: Chdir, Up: New Window - -Screen Command -============== - - - Command: screen [opts] [n] [cmd [args]] - (`C-a c', `C-a C-c') - Establish a new window. The flow-control options (`-f', `-fn' and - `-fa'), title option (`-t'), login options (`-l' and `-ln') , - terminal type option (`-T TERM'), the all-capability-flag (`-a') - and scrollback option (`-h NUM') may be specified with each - command. The option (`-M') turns monitoring on for this window. - The option (`-L') turns output logging on for this window. If an - optional number N in the range 0...9 is given, the window number N - is assigned to the newly created window (or, if this number is - already in-use, the next available number). If a command is - specified after `screen', this command (with the given arguments) - is started in the window; otherwise, a shell is created. - - Screen has built in some functionality of `cu' and `telnet'. - *Note Window Types::. - - Thus, if your `.screenrc' contains the lines - - # example for .screenrc: - screen 1 - screen -fn -t foobar 2 -L telnet foobar - -`screen' creates a shell window (in window #1) and a window with a -TELNET connection to the machine foobar (with no flow-control using the -title `foobar' in window #2) and will write a logfile `screenlog.2' of -the telnet session. If you do not include any `screen' commands in -your `.screenrc' file, then `screen' defaults to creating a single -shell window, number zero. When the initialization is completed, -`screen' switches to the last window specified in your .screenrc file -or, if none, it opens default window #0. - - -File: screen.info, Node: Setenv, Next: Shell, Prev: Screen Command, Up: New Window - -Setenv -====== - - - Command: setenv var string - (none) - Set the environment variable VAR to value STRING. If only VAR is - specified, the user will be prompted to enter a value. If no - parameters are specified, the user will be prompted for both - variable and value. The environment is inherited by all - subsequently forked shells. - - - Command: unsetenv var - (none) - Unset an environment variable. - - -File: screen.info, Node: Shell, Next: Term, Prev: Setenv, Up: New Window - -Shell -===== - - - Command: shell command - - Command: defshell command - (none) - Set the command to be used to create a new shell. This overrides - the value of the environment variable `$SHELL'. This is useful if - you'd like to run a tty-enhancer which is expecting to execute the - program specified in `$SHELL'. If the command begins with a `-' - character, the shell will be started as a login-shell. - - `defshell' is currently a synonym to the `shell' command. - - - Command: shelltitle title - (none) - Set the title for all shells created during startup or by the C-a - C-c command. *Note Naming Windows::, for details about what - titles are. - - -File: screen.info, Node: Term, Next: Window Types, Prev: Shell, Up: New Window - -Term -==== - - - Command: term term - (none) - In each window `screen' opens, it sets the `$TERM' variable to - `screen' by default, unless no description for `screen' is - installed in the local termcap or terminfo data base. In that - case it pretends that the terminal emulator is `vt100'. This - won't do much harm, as `screen' is VT100/ANSI compatible. The use - of the `term' command is discouraged for non-default purpose. - That is, one may want to specify special `$TERM' settings (e.g. - vt100) for the next `screen rlogin othermachine' command. Use the - command `screen -T vt100 rlogin othermachine' rather than setting - and resetting the default. - |
