33: .Sh DESCRIPTION
34: .Nm
1.59 jmc 35: is a terminal multiplexer:
36: it enables a number of terminals to be created, accessed, and
37: controlled from a single screen.
1.67 jmc 38: .Nm
39: may be detached from a screen
40: and continue running in the background,
41: then later reattached.
1.1 nicm 42: .Pp
1.60 nicm 43: When
44: .Nm
45: is started it creates a new
46: .Em session
47: with a single
48: .Em window
49: and displays it on screen.
50: A status line at the bottom of the screen
51: shows information on the current session
52: and is used to enter interactive commands.
53: .Pp
54: A session is a single collection of
55: .Em pseudo terminals
56: under the management of
57: .Nm .
58: Each session has one or more
59: windows linked to it.
60: A window occupies the entire screen
61: and may be split into rectangular panes,
62: each of which is a separate pseudo terminal
63: (the
64: .Xr pty 4
65: manual page documents the technical details of pseudo terminals).
66: Any number of
67: .Nm
68: instances may connect to the same session,
69: and any number of windows may be present in the same session.
70: Once all sessions are killed,
71: .Nm
72: exits.
73: .Pp
1.64 nicm 74: Each session is persistent and will survive accidental disconnection
1.66 jmc 75: (such as
1.64 nicm 76: .Xr ssh 1
1.67 jmc 77: connection timeout) or intentional detaching (with the
1.64 nicm 78: .Ql C-b d
79: key strokes).
80: .Nm
81: may be reattached using:
82: .Pp
83: .Dl $ tmux attach
1.60 nicm 84: .Pp
1.64 nicm 85: In
86: .Nm ,
87: a session is displayed on screen by a
88: .Em client
89: and all sessions are managed by a single
90: .Em server .
91: The server and each client are separate processes which communicate through a
92: socket in
93: .Pa /tmp .
1.65 nicm 94: .Pp
1.1 nicm 95: The options are as follows:
96: .Bl -tag -width "XXXXXXXXXXXX"
97: .It Fl 2
98: Force
99: .Nm
100: to assume the terminal supports 256 colours.
1.345 nicm 101: .It Fl C
102: Start in control mode.
103: Given twice
104: .Xo ( Fl CC ) Xc
105: disables echo.
1.91 nicm 106: .It Fl c Ar shell-command
107: Execute
108: .Ar shell-command
109: using the default shell.
110: If necessary, the
111: .Nm
112: server will be started to retrieve the
113: .Ic default-shell
114: option.
1.153 nicm 115: This option is for compatibility with
116: .Xr sh 1
117: when
118: .Nm
119: is used as a login shell.
1.1 nicm 120: .It Fl f Ar file
121: Specify an alternative configuration file.
122: By default,
123: .Nm
1.26 nicm 124: loads the system configuration file from
125: .Pa /etc/tmux.conf ,
126: if present, then looks for a user configuration file at
1.1 nicm 127: .Pa ~/.tmux.conf .
1.306 nicm 128: .Pp
1.1 nicm 129: The configuration file is a set of
130: .Nm
131: commands which are executed in sequence when the server is first started.
1.306 nicm 132: .Nm
133: loads configuration files once when the server process has started.
134: The
135: .Ic source-file
136: command may be used to load a file later.
1.61 nicm 137: .Pp
138: .Nm
1.306 nicm 139: shows any error messages from commands in configuration files in the first
140: session created, and continues to process the rest of the configuration file.
1.1 nicm 141: .It Fl L Ar socket-name
142: .Nm
143: stores the server socket in a directory under
1.208 nicm 144: .Pa /tmp
145: (or
146: .Ev TMPDIR
147: if set);
1.1 nicm 148: the default socket is named
149: .Em default .
150: This option allows a different socket name to be specified, allowing several
151: independent
152: .Nm
153: servers to be run.
154: Unlike
155: .Fl S
156: a full path is not necessary: the sockets are all created in the same
157: directory.
1.2 nicm 158: .Pp
159: If the socket is accidentally removed, the
1.6 jmc 160: .Dv SIGUSR1
1.2 nicm 161: signal may be sent to the
162: .Nm
163: server process to recreate it.
1.166 sobrado 164: .It Fl l
165: Behave as a login shell.
166: This flag currently has no effect and is for compatibility with other shells
167: when using tmux as a login shell.
1.4 sobrado 168: .It Fl q
1.133 nicm 169: Set the
170: .Ic quiet
171: server option to prevent the server sending various informational messages.
1.1 nicm 172: .It Fl S Ar socket-path
173: Specify a full alternative path to the server socket.
174: If
175: .Fl S
176: is specified, the default socket directory is not used and any
177: .Fl L
178: flag is ignored.
179: .It Fl u
180: .Nm
1.14 nicm 181: attempts to guess if the terminal is likely to support UTF-8 by checking the
182: first of the
183: .Ev LC_ALL ,
184: .Ev LC_CTYPE
185: and
1.2 nicm 186: .Ev LANG
1.14 nicm 187: environment variables to be set for the string "UTF-8".
1.5 nicm 188: This is not always correct: the
1.2 nicm 189: .Fl u
190: flag explicitly informs
191: .Nm
1.6 jmc 192: that UTF-8 is supported.
1.33 nicm 193: .Pp
194: If the server is started from a client passed
195: .Fl u
196: or where UTF-8 is detected, the
197: .Ic utf8
198: and
199: .Ic status-utf8
200: options are enabled in the global window and session options respectively.
1.1 nicm 201: .It Fl v
202: Request verbose logging.
203: This option may be specified multiple times for increasing verbosity.
204: Log messages will be saved into
205: .Pa tmux-client-PID.log
206: and
207: .Pa tmux-server-PID.log
208: files in the current directory, where
209: .Em PID
1.6 jmc 210: is the PID of the server or client process.
1.1 nicm 211: .It Ar command Op Ar flags
212: This specifies one of a set of commands used to control
213: .Nm ,
1.6 jmc 214: as described in the following sections.
1.59 jmc 215: If no commands are specified, the
1.1 nicm 216: .Ic new-session
217: command is assumed.
1.57 jmc 218: .El
1.64 nicm 219: .Sh KEY BINDINGS
220: .Nm
221: may be controlled from an attached client by using a key combination of a
222: prefix key,
223: .Ql C-b
224: (Ctrl-b) by default, followed by a command key.
225: .Pp
1.172 nicm 226: The default command key bindings are:

338: and
339: .Ic unbind-key
340: commands.
1.57 jmc 341: .Sh COMMANDS
342: This section contains a list of the commands supported by
343: .Nm .
344: Most commands accept the optional
345: .Fl t
346: argument with one of
347: .Ar target-client ,
348: .Ar target-session
349: .Ar target-window ,
350: or
351: .Ar target-pane .
352: These specify the client, session, window or pane which a command should affect.
353: .Ar target-client
354: is the name of the
355: .Xr pty 4
356: file to which the client is connected, for example either of
357: .Pa /dev/ttyp1
358: or
359: .Pa ttyp1
360: for the client attached to
361: .Pa /dev/ttyp1 .
362: If no client is specified, the current client is chosen, if possible, or an
363: error is reported.
364: Clients may be listed with the
365: .Ic list-clients
366: command.
1.1 nicm 367: .Pp
1.57 jmc 368: .Ar target-session
1.344 nicm 369: is the session id prefixed with a $, the name of a session (as listed by the
1.57 jmc 370: .Ic list-sessions
1.344 nicm 371: command), or the name of a client with the same syntax as
1.57 jmc 372: .Ar target-client ,
373: in which case the session attached to the client is used.
374: When looking for the session name,
375: .Nm
376: initially searches for an exact match; if none is found, the session names
377: are checked for any for which
378: .Ar target-session
379: is a prefix or for which it matches as an
380: .Xr fnmatch 3
381: pattern.
382: If a single match is found, it is used as the target session; multiple matches
383: produce an error.
384: If a session is omitted, the current session is used if available; if no
1.117 nicm 385: current session is available, the most recently used is chosen.
1.1 nicm 386: .Pp
1.57 jmc 387: .Ar target-window
388: specifies a window in the form
389: .Em session Ns \&: Ns Em window .
390: .Em session
391: follows the same rules as for
392: .Ar target-session ,
393: and
394: .Em window
1.270 nicm 395: is looked for in order: as a window index, for example mysession:1;
1.271 jmc 396: as a window ID, such as @1;
1.270 nicm 397: as an exact window name, such as mysession:mywindow; then as an
1.57 jmc 398: .Xr fnmatch 3
399: pattern or the start of a window name, such as mysession:mywin* or
400: mysession:mywin.
401: An empty window name specifies the next unused index if appropriate (for
402: example the
403: .Ic new-window
404: and
405: .Ic link-window
406: commands)
407: otherwise the current window in
408: .Em session
409: is chosen.
1.140 nicm 410: The special character
411: .Ql \&!
1.311 nicm 412: uses the last (previously current) window,
413: .Ql ^
414: selects the highest numbered window,
415: .Ql $
416: selects the lowest numbered window, and
1.140 nicm 417: .Ql +
418: and
419: .Ql -
1.311 nicm 420: select the next window or the previous window by number.
1.57 jmc 421: When the argument does not contain a colon,
422: .Nm
423: first attempts to parse it as window; if that fails, an attempt is made to
424: match a session.
1.1 nicm 425: .Pp
1.57 jmc 426: .Ar target-pane
427: takes a similar form to
428: .Ar target-window
429: but with the optional addition of a period followed by a pane index, for
430: example: mysession:mywindow.1.
431: If the pane index is omitted, the currently active pane in the specified
432: window is used.
433: If neither a colon nor period appears,
1.13 nicm 434: .Nm
1.57 jmc 435: first attempts to use the argument as a pane index; if that fails, it is looked
436: up as for
437: .Ar target-window .
1.156 nicm 438: A
439: .Ql +
440: or
441: .Ql -
442: indicate the next or previous pane index, respectively.
1.132 nicm 443: One of the strings
444: .Em top ,
445: .Em bottom ,
446: .Em left ,
447: .Em right ,
448: .Em top-left ,
449: .Em top-right ,
1.216 nicm 450: .Em bottom-left
451: or
1.132 nicm 452: .Em bottom-right
453: may be used instead of a pane index.
1.177 nicm 454: .Pp
455: The special characters
456: .Ql +
457: and
458: .Ql -
459: may be followed by an offset, for example:
460: .Bd -literal -offset indent
461: select-window -t:+2
462: .Ed
463: .Pp
464: When dealing with a session that doesn't contain sequential window indexes,
465: they will be correctly skipped.
1.212 nicm 466: .Pp
467: .Nm
468: also gives each pane created in a server an identifier consisting of a
469: .Ql %
470: and a number, starting from zero.
471: A pane's identifier is unique for the life of the
472: .Nm
473: server and is passed to the child process of the pane in the
474: .Ev TMUX_PANE
475: environment variable.
476: It may be used alone to target a pane or the window containing it.
1.15 jmc 477: .Pp
1.153 nicm 478: .Ar shell-command
479: arguments are
480: .Xr sh 1
481: commands.
482: These must be passed as a single item, which typically means quoting them, for
483: example:
484: .Bd -literal -offset indent
485: new-window 'vi /etc/passwd'
486: .Ed
487: .Pp
488: .Ar command
489: .Op Ar arguments
490: refers to a
491: .Nm
492: command, passed with the command and arguments separately, for example:
493: .Bd -literal -offset indent
494: bind-key F1 set-window-option force-width 81
495: .Ed
496: .Pp
497: Or if using
498: .Xr sh 1 :
499: .Bd -literal -offset indent
500: $ tmux bind-key F1 set-window-option force-width 81
501: .Ed
502: .Pp
1.57 jmc 503: Multiple commands may be specified together as part of a
504: .Em command sequence .
505: Each command should be separated by spaces and a semicolon;
1.244 nicm 506: commands are executed sequentially from left to right and
1.293 nicm 507: lines ending with a backslash continue on to the next line,
508: except when escaped by another backslash.
1.57 jmc 509: A literal semicolon may be included by escaping it with a backslash (for
510: example, when specifying a command sequence to
511: .Ic bind-key ) .
1.13 nicm 512: .Pp
1.153 nicm 513: Example
514: .Nm
515: commands include:
1.13 nicm 516: .Bd -literal -offset indent
1.57 jmc 517: refresh-client -t/dev/ttyp2

1.57 jmc 538: .Sh CLIENTS AND SESSIONS
1.153 nicm 539: The
540: .Nm
541: server manages clients, sessions, windows and panes.
542: Clients are attached to sessions to interact with them, either
543: when they are created with the
544: .Ic new-session
545: command, or later with the
546: .Ic attach-session
547: command.
1.188 nicm 548: Each session has one or more windows
1.153 nicm 549: .Em linked
550: into it.
551: Windows may be linked to multiple sessions and are made up of one or
552: more panes,

3109: Windows and sessions have names, which may be used to specify them in targets
3110: and are displayed in the status line and various lists: the name is the
3111: .Nm
3112: identifier for a window or session.
3113: Only panes have titles.
3114: A pane's title is typically set by the program running inside the pane and
3115: is not modified by
3116: .Nm .
3117: It is the same mechanism used to set for example the
3118: .Xr xterm 1
3119: window title in an

3121: window manager.
1.268 nicm 3122: Windows themselves do not have titles - a window's title is the title of its
