From eda6f5931d42c77e1480347b1fc3eef2f8d33806 Mon Sep 17 00:00:00 2001 From: David van Moolenbroek Date: Wed, 1 Oct 2014 15:59:46 +0000 Subject: [PATCH] Import tmux We have to use SOCK_SEQPACKET instead of SOCK_STREAM for client/server communication, because UDS does things with control messages that tmux does not expect.

command Op Ar flags +.Ek +.Sh DESCRIPTION +.Nm +is a terminal multiplexer: +it enables a number of terminals to be created, accessed, and +controlled from a single screen. +.Nm +may be detached from a screen +and continue running in the background, +then later reattached. +.Pp +When +.Nm +is started it creates a new +.Em session +with a single +.Em window +and displays it on screen. +A status line at the bottom of the screen +shows information on the current session +and is used to enter interactive commands. +.Pp +A session is a single collection of +.Em pseudo terminals +under the management of +.Nm . +Each session has one or more +windows linked to it. +A window occupies the entire screen +and may be split into rectangular panes, +each of which is a separate pseudo terminal +(the +.Xr pty 4 +manual page documents the technical details of pseudo terminals). +Any number of +.Nm +instances may connect to the same session, +and any number of windows may be present in the same session. +Once all sessions are killed, +.Nm +exits. +.Pp +Each session is persistent and will survive accidental disconnection +(such as +.Xr ssh 1 +connection timeout) or intentional detaching (with the +.Ql C-b d +key strokes). +.Nm +may be reattached using: +.Pp +.Dl $ tmux attach +.Pp +In +.Nm , +a session is displayed on screen by a +.Em client +and all sessions are managed by a single +.Em server . +The server and each client are separate processes which communicate through a +socket in +.Pa /tmp . +.Pp +The options are as follows: +.Bl -tag -width "XXXXXXXXXXXX" +.It Fl 2 +Force +.Nm +to assume the terminal supports 256 colours. +.It Fl 8 +Like +.Fl 2 , +but indicates that the terminal supports 88 colours. +.It Fl c Ar shell-command +Execute +.Ar shell-command +using the default shell. +If necessary, the +.Nm +server will be started to retrieve the +.Ic default-shell +option. +This option is for compatibility with +.Xr sh 1 +when +.Nm +is used as a login shell. +.It Fl f Ar file +Specify an alternative configuration file. +By default, +.Nm +loads the system configuration file from +.Pa /etc/tmux.conf , +if present, then looks for a user configuration file at +.Pa ~/.tmux.conf . +The configuration file is a set of +.Nm +commands which are executed in sequence when the server is first started. +.Pp +If a command in the configuration file fails, +.Nm +will report an error and exit without executing further commands. +.It Fl L Ar socket-name +.Nm +stores the server socket in a directory under +.Pa /tmp +(or +.Ev TMPDIR +if set); +the default socket is named +.Em default . +This option allows a different socket name to be specified, allowing several +independent +.Nm +servers to be run. +Unlike +.Fl S +a full path is not necessary: the sockets are all created in the same +directory. +.Pp +If the socket is accidentally removed, the +.Dv SIGUSR1 +signal may be sent to the +.Nm +server process to recreate it. +.It Fl l +Behave as a login shell. +This flag currently has no effect and is for compatibility with other shells +when using tmux as a login shell. +.It Fl q +Set the +.Ic quiet +server option to prevent the server sending various informational messages. +.It Fl S Ar socket-path +Specify a full alternative path to the server socket. +If +.Fl S +is specified, the default socket directory is not used and any +.Fl L +flag is ignored. +.It Fl u +.Nm +attempts to guess if the terminal is likely to support UTF-8 by checking the +first of the +.Ev LC_ALL , +.Ev LC_CTYPE +and +.Ev LANG +environment variables to be set for the string "UTF-8". +This is not always correct: the +.Fl u +flag explicitly informs +.Nm +that UTF-8 is supported. +.Pp +If the server is started from a client passed +.Fl u +or where UTF-8 is detected, the +.Ic utf8 +and +.Ic status-utf8 +options are enabled in the global window and session options respectively. +.It Fl v +Request verbose logging. +This option may be specified multiple times for increasing verbosity. +Log messages will be saved into +.Pa tmux-client-PID.log +and +.Pa tmux-server-PID.log +files in the current directory, where +.Em PID +is the PID of the server or client process. +.It Fl V +Report the +.Nm +version. +.It Ar command Op Ar flags +This specifies one of a set of commands used to control +.Nm , +as described in the following sections. +If no commands are specified, the +.Ic new-session +command is assumed. +.El +.Sh KEY BINDINGS +.Nm +may be controlled from an attached client by using a key combination of a +prefix key, +.Ql C-b +(Ctrl-b) by default, followed by a command key. +.Pp +The default command key bindings are: +.Pp +.Bl -tag -width "XXXXXXXXXX" -offset indent -compact +.It C-b +Send the prefix key (C-b) through to the application. +.It C-o +Rotate the panes in the current window forwards. +.It C-z +Suspend the +.Nm +client. +.It ! +Break the current pane out of the window. +.It \&" +Split the current pane into two, top and bottom. +.It # +List all paste buffers. +.It $ +Rename the current session. +.It % +Split the current pane into two, left and right. +.It & +Kill the current window. +.It ' +Prompt for a window index to select. +.It , +Rename the current window. +.It - +Delete the most recently copied buffer of text. +.It . +Prompt for an index to move the current window. +.It 0 to 9 +Select windows 0 to 9. +.It : +Enter the +.Nm +command prompt. +.It ; +Move to the previously active pane. +.It = +Choose which buffer to paste interactively from a list. +.It \&? +List all key bindings. +.It D +Choose a client to detach. +.It \&[ +Enter copy mode to copy text or view the history. +.It \&] +Paste the most recently copied buffer of text. +.It c +Create a new window. +.It d +Detach the current client. +.It f +Prompt to search for text in open windows. +.It i +Display some information about the current window. +.It l +Move to the previously selected window. +.It n +Change to the next window. +.It o +Select the next pane in the current window. +.It p +Change to the previous window. +.It q +Briefly display pane indexes. +.It r +Force redraw of the attached client. +.It s +Select a new session for the attached client interactively. +.It L +Switch the attached client back to the last session. +.It t +Show the time. +.It w +Choose the current window interactively. +.It x +Kill the current pane. +.It { +Swap the current pane with the previous pane. +.It } +Swap the current pane with the next pane. +.It ~ +Show previous messages from +.Nm , +if any. +.It Page Up +Enter copy mode and scroll one page up. +.It Up, Down +.It Left, Right +Change to the pane above, below, to the left, or to the right of the current +pane. +.It M-1 to M-5 +Arrange panes in one of the five preset layouts: even-horizontal, +even-vertical, main-horizontal, main-vertical, or tiled. +.It M-n +Move to the next window with a bell or activity marker. +.It M-o +Rotate the panes in the current window backwards. +.It M-p +Move to the previous window with a bell or activity marker. +.It C-Up, C-Down +.It C-Left, C-Right +Resize the current pane in steps of one cell. +.It M-Up, M-Down +.It M-Left, M-Right +Resize the current pane in steps of five cells. +.El +.Pp +Key bindings may be changed with the +.Ic bind-key +and +.Ic unbind-key +commands. +.Sh COMMANDS +This section contains a list of the commands supported by +.Nm . +Most commands accept the optional +.Fl t +argument with one of +.Ar target-client , +.Ar target-session +.Ar target-window , +or +.Ar target-pane . +These specify the client, session, window or pane which a command should affect. +.Ar target-client +is the name of the +.Xr pty 4 +file to which the client is connected, for example either of +.Pa /dev/ttyp1 +or +.Pa ttyp1 +for the client attached to +.Pa /dev/ttyp1 . +If no client is specified, the current client is chosen, if possible, or an +error is reported. +Clients may be listed with the +.Ic list-clients +command. +.Pp +.Ar target-session +is either the name of a session (as listed by the +.Ic list-sessions +command) or the name of a client with the same syntax as +.Ar target-client , +in which case the session attached to the client is used. +When looking for the session name, +.Nm +initially searches for an exact match; if none is found, the session names +are checked for any for which +.Ar target-session +is a prefix or for which it matches as an +.Xr fnmatch 3 +pattern. +If a single match is found, it is used as the target session; multiple matches +produce an error. +If a session is omitted, the current session is used if available; if no +current session is available, the most recently used is chosen. +.Pp +.Ar target-window +specifies a window in the form +.Em session Ns \&: Ns Em window . +.Em session +follows the same rules as for +.Ar target-session , +and +.Em window +is looked for in order: as a window index, for example mysession:1; as an exact +window name, such as mysession:mywindow; then as an +.Xr fnmatch 3 +pattern or the start of a window name, such as mysession:mywin* or +mysession:mywin. +An empty window name specifies the next unused index if appropriate (for +example the +.Ic new-window +and +.Ic link-window +commands) +otherwise the current window in +.Em session +is chosen. +The special character +.Ql \&! +uses the last (previously current) window, or +.Ql + +and +.Ql - +are the next window or the previous window by number. +When the argument does not contain a colon, +.Nm +first attempts to parse it as window; if that fails, an attempt is made to +match a session. +.Pp +.Ar target-pane +takes a similar form to +.Ar target-window +but with the optional addition of a period followed by a pane index, for +example: mysession:mywindow.1. +If the pane index is omitted, the currently active pane in the specified +window is used. +If neither a colon nor period appears, +.Nm +first attempts to use the argument as a pane index; if that fails, it is looked +up as for +.Ar target-window . +A +.Ql + +or +.Ql - +indicate the next or previous pane index, respectively. +One of the strings +.Em top , +.Em bottom , +.Em left , +.Em right , +.Em top-left , +.Em top-right , +.Em bottom-left +or +.Em bottom-right +may be used instead of a pane index. +.Pp +The special characters +.Ql + +and +.Ql - +may be followed by an offset, for example: +.Bd -literal -offset indent +select-window -t:+2 +.Ed +.Pp +When dealing with a session that doesn't contain sequential window indexes, +they will be correctly skipped. +.Pp +.Nm +also gives each pane created in a server an identifier consisting of a +.Ql % +and a number, starting from zero. +A pane's identifier is unique for the life of the +.Nm +server and is passed to the child process of the pane in the +.Ev TMUX_PANE +environment variable. +It may be used alone to target a pane or the window containing it. +.Pp +.Ar shell-command +arguments are +.Xr sh 1 +commands. +These must be passed as a single item, which typically means quoting them, for +example: +.Bd -literal -offset indent +new-window 'vi /etc/passwd' +.Ed +.Pp +.Ar command +.Op Ar arguments +refers to a +.Nm +command, passed with the command and arguments separately, for example: +.Bd -literal -offset indent +bind-key F1 set-window-option force-width 81 +.Ed +.Pp +Or if using +.Xr sh 1 : +.Bd -literal -offset indent +$ tmux bind-key F1 set-window-option force-width 81 +.Ed +.Pp +Multiple commands may be specified together as part of a +.Em command sequence . +Each command should be separated by spaces and a semicolon; +commands are executed sequentially from left to right. +A literal semicolon may be included by escaping it with a backslash (for +example, when specifying a command sequence to +.Ic bind-key ) . +.Pp +Example +.Nm +commands include: +.Bd -literal -offset indent +refresh-client -t/dev/ttyp2 + +rename-session -tfirst newname + +set-window-option -t:0 monitor-activity on + +new-window ; split-window -d +.Ed +.Pp +Or from +.Xr sh 1 : +.Bd -literal -offset indent +$ tmux kill-window -t :1 + +$ tmux new-window \e; split-window -d + +$ tmux new-session -d 'vi /etc/passwd' \e; split-window -d \e; attach +.Ed +.Sh CLIENTS AND SESSIONS +The +.Nm +server manages clients, sessions, windows and panes. +Clients are attached to sessions to interact with them, either +when they are created with the +.Ic new-session +command, or later with the +.Ic attach-session +command. +Each session has one or more windows +.Em linked +into it. +Windows may be linked to multiple sessions and are made up of one or +more panes, +each of which contains a pseudo terminal. +Commands for creating, linking and otherwise manipulating windows +are covered +in the +.Sx WINDOWS AND PANES +section. +.Pp +The following commands are available to manage clients and sessions: +.Bl -tag -width Ds +.It Xo Ic attach-session +.Op Fl dr +.Op Fl t Ar target-session +.Xc +.D1 (alias: Ic attach ) +If run from outside +.Nm , +create a new client in the current terminal and attach it to +.Ar target-session . +If used from inside, switch the current client. +If +.Fl d +is specified, any other clients attached to the session are detached. +.Fl r +signifies the client is read-only (only keys bound to the +.Ic detach-client +command have any effect) +.Pp +If no server is started, +.Ic attach-session +will attempt to start it; this will fail unless sessions are created in the +configuration file. +.Pp +The +.Ar target-session +rules for +.Ic attach-session +are slightly adjusted: if +.Nm +needs to select the most recently used session, it will prefer the most +recently used +.Em unattached +session. +.It Xo Ic detach-client +.Op Fl P +.Op Fl s Ar target-session +.Op Fl t Ar target-client +.Xc +.D1 (alias: Ic detach ) +Detach the current client if bound to a key, the client specified with +.Fl t , +or all clients currently attached to to the session specified by +.Fl s . +If +.Fl P +is given, send SIGHUP to the parent process of the client, typically causing it +to exit. +.It Ic has-session Op Fl t Ar target-session +.D1 (alias: Ic has ) +Report an error and exit with 1 if the specified session does not exist. +If it does exist, exit with 0. +.It Ic kill-server +Kill the +.Nm +server and clients and destroy all sessions. +.It Ic kill-session Op Fl t Ar target-session +Destroy the given session, closing any windows linked to it and no other +sessions, and detaching all clients attached to it. +.It Ic list-clients Op Fl t Ar target-session +.D1 (alias: Ic lsc ) +List all clients attached to the server. +If +.Ar target-session +is specified, list only clients connected to that session. +.It Ic list-commands +.D1 (alias: Ic lscm ) +List the syntax of all commands supported by +.Nm . +.It Ic list-sessions +.D1 (alias: Ic ls ) +List all sessions managed by the server. +.It Ic lock-client Op Fl t Ar target-client +.D1 (alias: Ic lockc ) +Lock +.Ar target-client , +see the +.Ic lock-server +command. +.It Ic lock-session Op Fl t Ar target-session +.D1 (alias: Ic locks ) +Lock all clients attached to +.Ar target-session . +.It Xo Ic new-session +.Op Fl d +.Op Fl n Ar window-name +.Op Fl s Ar session-name +.Op Fl t Ar target-session +.Op Fl x Ar width +.Op Fl y Ar height +.Op Ar shell-command +.Xc +.D1 (alias: Ic new ) +Create a new session with name +.Ar session-name . +.Pp +The new session is attached to the current terminal unless +.Fl d +is given. +.Ar window-name +and +.Ar shell-command +are the name of and shell command to execute in the initial window. +If +.Fl d +is used, +.Fl x +and +.Fl y +specify the size of the initial window (80 by 24 if not given). +.Pp +If run from a terminal, any +.Xr termios 4 +special characters are saved and used for new windows in the new session. +.Pp +If +.Fl t +is given, the new session is +.Em grouped +with +.Ar target-session . +This means they share the same set of windows - all windows from +.Ar target-session +are linked to the new session and any subsequent new windows or windows being +closed are applied to both sessions. +The current and previous window and any session options remain independent and +either session may be killed without affecting the other. +Giving +.Fl n +or +.Ar shell-command +are invalid if +.Fl t +is used. +.It Ic refresh-client Op Fl t Ar target-client +.D1 (alias: Ic refresh ) +Refresh the current client if bound to a key, or a single client if one is given +with +.Fl t . +.It Xo Ic rename-session +.Op Fl t Ar target-session +.Ar new-name +.Xc +.D1 (alias: Ic rename ) +Rename the session to +.Ar new-name . +.It Xo Ic show-messages +.Op Fl t Ar target-client +.Xc +.D1 (alias: Ic showmsgs ) +Any messages displayed on the status line are saved in a per-client message +log, up to a maximum of the limit set by the +.Ar message-limit +session option for the session attached to that client. +This command displays the log for +.Ar target-client . +.It Ic source-file Ar path +.D1 (alias: Ic source ) +Execute commands from +.Ar path . +.It Ic start-server +.D1 (alias: Ic start ) +Start the +.Nm +server, if not already running, without creating any sessions. +.It Xo Ic suspend-client +.Op Fl t Ar target-client +.Xc +.D1 (alias: Ic suspendc ) +Suspend a client by sending +.Dv SIGTSTP +(tty stop). +.It Xo Ic switch-client +.Op Fl lnp +.Op Fl c Ar target-client +.Op Fl t Ar target-session +.Xc +.D1 (alias: Ic switchc ) +Switch the current session for client +.Ar target-client +to +.Ar target-session . +If +.Fl l , +.Fl n +or +.Fl p +is used, the client is moved to the last, next or previous session +respectively. +.El +.Sh WINDOWS AND PANES +A +.Nm +window may be in one of several modes. +The default permits direct access to the terminal attached to the window. +The other is copy mode, which permits a section of a window or its +history to be copied to a +.Em paste buffer +for later insertion into another window. +This mode is entered with the +.Ic copy-mode +command, bound to +.Ql \&[ +by default. +It is also entered when a command that produces output, such as +.Ic list-keys , +is executed from a key binding. +.Pp +The keys available depend on whether emacs or vi mode is selected +(see the +.Ic mode-keys +option). +The following keys are supported as appropriate for the mode: +.Bl -column "FunctionXXXXXXXXXXXXXXXXX" "viXXXXXXXXXX" "emacs" -offset indent +.It Sy "Function" Ta Sy "vi" Ta Sy "emacs" +.It Li "Back to indentation" Ta "^" Ta "M-m" +.It Li "Bottom of history" Ta "G" Ta "M-<" +.It Li "Clear selection" Ta

chars" Ta "" Ta "C-t" +.El +.Pp +The next and previous word keys use space and the +.Ql - , +.Ql _ +and +.Ql @ +characters as word delimiters by default, but this can be adjusted by +setting the +.Em word-separators +window option. +Next word moves to the start of the next word, next word end to the end of the +next word and previous word to the start of the previous word. +The three next and previous space keys work similarly but use a space alone as +the word separator. +.Pp +The jump commands enable quick movement within a line. +For instance, typing +.Ql f +followed by +.Ql / +will move the cursor to the next +.Ql / +character on the current line. +A +.Ql \&; +will then jump to the next occurrence. +.Pp +Commands in copy mode may be prefaced by an optional repeat count. +With vi key bindings, a prefix is entered using the number keys; with +emacs, the Alt (meta) key and a number begins prefix entry. +For example, to move the cursor forward by ten words, use +.Ql M-1 0 M-f +in emacs mode, and +.Ql 10w +in vi. +.Pp +Mode key bindings are defined in a set of named tables: +.Em vi-edit +and +.Em emacs-edit +for keys used when line editing at the command prompt; +.Em vi-choice

+.Pp +Each window displayed by +.Nm +may be split into one or more +.Em panes ; +each pane takes up a certain area of the display and is a separate terminal. +A window may be split into panes using the +.Ic split-window +command. +Windows may be split horizontally (with the +.Fl h +flag) or vertically. +Panes may be resized with the +.Ic resize-pane +command (bound to +.Ql C-up , +.Ql C-down +.Ql C-left +and +.Ql C-right +by default), the current pane may be changed with the +.Ic select-pane +command and the +.Ic rotate-window +and +.Ic swap-pane +commands may be used to swap panes without changing their position. +Panes are numbered beginning from zero in the order they are created. +.Pp +A number of preset +.Em layouts +are available. +These may be selected with the +.Ic

which do not have a particular option configured inherit the value +from the global session options. +Session options are set or unset with the +.Ic set-option +command and may be listed with the +.Ic show-options +command. +The available server and session options are listed under the +.Ic set-option +command. +.Pp +Similarly, a set of window options is attached to each window, and there is +a set of global window options from which any unset options are inherited. +Window options are altered with the +.Ic set-window-option +command and can be listed with the +.Ic show-window-options +command.
