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.
101: .It Fl 8
102: Like
103: .Fl 2 ,
1.6 jmc 104: but indicates that the terminal supports 88 colours.
1.345 nicm 105: .It Fl C
106: Start in control mode.
107: Given twice
108: .Xo ( Fl CC ) Xc
109: disables echo.
1.91 nicm 110: .It Fl c Ar shell-command
111: Execute
112: .Ar shell-command
113: using the default shell.
114: If necessary, the
115: .Nm
116: server will be started to retrieve the
117: .Ic default-shell
118: option.
1.153 nicm 119: This option is for compatibility with
120: .Xr sh 1
121: when
122: .Nm
123: is used as a login shell.
1.1 nicm 124: .It Fl f Ar file
125: Specify an alternative configuration file.
126: By default,
127: .Nm
1.26 nicm 128: loads the system configuration file from
129: .Pa /etc/tmux.conf ,
130: if present, then looks for a user configuration file at
1.1 nicm 131: .Pa ~/.tmux.conf .
1.306 nicm 132: .Pp
1.1 nicm 133: The configuration file is a set of
134: .Nm
135: commands which are executed in sequence when the server is first started.
1.306 nicm 136: .Nm
137: loads configuration files once when the server process has started.
138: The
139: .Ic source-file
140: command may be used to load a file later.
1.61 nicm 141: .Pp
142: .Nm
1.306 nicm 143: shows any error messages from commands in configuration files in the first
144: session created, and continues to process the rest of the configuration file.
1.1 nicm 145: .It Fl L Ar socket-name
146: .Nm
147: stores the server socket in a directory under
1.208 nicm 148: .Pa /tmp
149: (or
150: .Ev TMPDIR
151: if set);
1.1 nicm 152: the default socket is named
153: .Em default .
154: This option allows a different socket name to be specified, allowing several
155: independent
156: .Nm
157: servers to be run.
158: Unlike
159: .Fl S
160: a full path is not necessary: the sockets are all created in the same
161: directory.
1.2 nicm 162: .Pp
163: If the socket is accidentally removed, the
1.6 jmc 164: .Dv SIGUSR1
1.2 nicm 165: signal may be sent to the
166: .Nm
167: server process to recreate it.
1.166 sobrado 168: .It Fl l
169: Behave as a login shell.
170: This flag currently has no effect and is for compatibility with other shells
171: when using tmux as a login shell.
1.4 sobrado 172: .It Fl q
1.133 nicm 173: Set the
174: .Ic quiet
175: server option to prevent the server sending various informational messages.
1.1 nicm 176: .It Fl S Ar socket-path
177: Specify a full alternative path to the server socket.
178: If
179: .Fl S
180: is specified, the default socket directory is not used and any
181: .Fl L
182: flag is ignored.
183: .It Fl u
184: .Nm
1.14 nicm 185: attempts to guess if the terminal is likely to support UTF-8 by checking the
186: first of the
187: .Ev LC_ALL ,
188: .Ev LC_CTYPE
189: and
1.2 nicm 190: .Ev LANG
1.14 nicm 191: environment variables to be set for the string "UTF-8".
1.5 nicm 192: This is not always correct: the
1.2 nicm 193: .Fl u
194: flag explicitly informs
195: .Nm
1.6 jmc 196: that UTF-8 is supported.
1.33 nicm 197: .Pp
198: If the server is started from a client passed
199: .Fl u
200: or where UTF-8 is detected, the
201: .Ic utf8
202: and
203: .Ic status-utf8
204: options are enabled in the global window and session options respectively.
1.1 nicm 205: .It Fl v
206: Request verbose logging.
207: This option may be specified multiple times for increasing verbosity.
208: Log messages will be saved into
209: .Pa tmux-client-PID.log
210: and
211: .Pa tmux-server-PID.log
212: files in the current directory, where
213: .Em PID
1.6 jmc 214: is the PID of the server or client process.
1.1 nicm 215: .It Ar command Op Ar flags
216: This specifies one of a set of commands used to control
217: .Nm ,
1.6 jmc 218: as described in the following sections.
1.59 jmc 219: If no commands are specified, the
1.1 nicm 220: .Ic new-session
221: command is assumed.
1.57 jmc 222: .El
1.64 nicm 223: .Sh KEY BINDINGS
224: .Nm
225: may be controlled from an attached client by using a key combination of a
226: prefix key,
227: .Ql C-b
228: (Ctrl-b) by default, followed by a command key.
229: .Pp
1.172 nicm 230: The default command key bindings are:

342: and
343: .Ic unbind-key
344: commands.
1.57 jmc 345: .Sh COMMANDS
346: This section contains a list of the commands supported by
347: .Nm .
348: Most commands accept the optional
349: .Fl t
350: argument with one of
351: .Ar target-client ,
352: .Ar target-session
353: .Ar target-window ,
354: or
355: .Ar target-pane .
356: These specify the client, session, window or pane which a command should affect.
357: .Ar target-client
358: is the name of the
359: .Xr pty 4
360: file to which the client is connected, for example either of
361: .Pa /dev/ttyp1
362: or
363: .Pa ttyp1
364: for the client attached to
365: .Pa /dev/ttyp1 .
366: If no client is specified, the current client is chosen, if possible, or an
367: error is reported.
368: Clients may be listed with the
369: .Ic list-clients
370: command.
1.1 nicm 371: .Pp
1.57 jmc 372: .Ar target-session
1.344 nicm 373: is the session id prefixed with a $, the name of a session (as listed by the
1.57 jmc 374: .Ic list-sessions
1.344 nicm 375: command), or the name of a client with the same syntax as
1.57 jmc 376: .Ar target-client ,
377: in which case the session attached to the client is used.
378: When looking for the session name,
379: .Nm
380: initially searches for an exact match; if none is found, the session names
381: are checked for any for which
382: .Ar target-session
383: is a prefix or for which it matches as an
384: .Xr fnmatch 3
385: pattern.
386: If a single match is found, it is used as the target session; multiple matches
387: produce an error.
388: If a session is omitted, the current session is used if available; if no
1.117 nicm 389: current session is available, the most recently used is chosen.
1.1 nicm 390: .Pp
1.57 jmc 391: .Ar target-window
392: specifies a window in the form
393: .Em session Ns \&: Ns Em window .
394: .Em session
395: follows the same rules as for
396: .Ar target-session ,
397: and
398: .Em window
1.270 nicm 399: is looked for in order: as a window index, for example mysession:1;
1.271 jmc 400: as a window ID, such as @1;
1.270 nicm 401: as an exact window name, such as mysession:mywindow; then as an
1.57 jmc 402: .Xr fnmatch 3
403: pattern or the start of a window name, such as mysession:mywin* or
404: mysession:mywin.
405: An empty window name specifies the next unused index if appropriate (for
406: example the
407: .Ic new-window
408: and
409: .Ic link-window
410: commands)
411: otherwise the current window in
412: .Em session
413: is chosen.
1.140 nicm 414: The special character
415: .Ql \&!
1.311 nicm 416: uses the last (previously current) window,
417: .Ql ^
418: selects the highest numbered window,
419: .Ql $
420: selects the lowest numbered window, and
1.140 nicm 421: .Ql +
422: and
423: .Ql -
1.311 nicm 424: select the next window or the previous window by number.
1.57 jmc 425: When the argument does not contain a colon,
426: .Nm
427: first attempts to parse it as window; if that fails, an attempt is made to
428: match a session.
1.1 nicm 429: .Pp
1.57 jmc 430: .Ar target-pane
431: takes a similar form to
432: .Ar target-window
433: but with the optional addition of a period followed by a pane index, for
434: example: mysession:mywindow.1.
435: If the pane index is omitted, the currently active pane in the specified
436: window is used.
437: If neither a colon nor period appears,
1.13 nicm 438: .Nm
1.57 jmc 439: first attempts to use the argument as a pane index; if that fails, it is looked
440: up as for
441: .Ar target-window .
1.156 nicm 442: A
443: .Ql +
444: or
445: .Ql -
446: indicate the next or previous pane index, respectively.
1.132 nicm 447: One of the strings
448: .Em top ,
449: .Em bottom ,
450: .Em left ,
451: .Em right ,
452: .Em top-left ,
453: .Em top-right ,
1.216 nicm 454: .Em bottom-left
455: or
1.132 nicm 456: .Em bottom-right
457: may be used instead of a pane index.
1.177 nicm 458: .Pp
459: The special characters
460: .Ql +
461: and
462: .Ql -
463: may be followed by an offset, for example:
464: .Bd -literal -offset indent
465: select-window -t:+2
466: .Ed
467: .Pp
468: When dealing with a session that doesn't contain sequential window indexes,
469: they will be correctly skipped.
1.212 nicm 470: .Pp
471: .Nm
472: also gives each pane created in a server an identifier consisting of a
473: .Ql %
474: and a number, starting from zero.
475: A pane's identifier is unique for the life of the
476: .Nm
477: server and is passed to the child process of the pane in the
478: .Ev TMUX_PANE
479: environment variable.
480: It may be used alone to target a pane or the window containing it.
1.15 jmc 481: .Pp
1.153 nicm 482: .Ar shell-command
483: arguments are
484: .Xr sh 1
485: commands.
486: These must be passed as a single item, which typically means quoting them, for
487: example:
488: .Bd -literal -offset indent
489: new-window 'vi /etc/passwd'
490: .Ed
491: .Pp
492: .Ar command
493: .Op Ar arguments
494: refers to a
495: .Nm
496: command, passed with the command and arguments separately, for example:
497: .Bd -literal -offset indent
498: bind-key F1 set-window-option force-width 81
499: .Ed
500: .Pp
501: Or if using
502: .Xr sh 1 :
503: .Bd -literal -offset indent
504: $ tmux bind-key F1 set-window-option force-width 81
505: .Ed
506: .Pp
1.57 jmc 507: Multiple commands may be specified together as part of a
508: .Em command sequence .
509: Each command should be separated by spaces and a semicolon;
1.244 nicm 510: commands are executed sequentially from left to right and
1.293 nicm 511: lines ending with a backslash continue on to the next line,
512: except when escaped by another backslash.
1.57 jmc 513: A literal semicolon may be included by escaping it with a backslash (for
514: example, when specifying a command sequence to
515: .Ic bind-key ) .
1.13 nicm 516: .Pp
1.153 nicm 517: Example
518: .Nm
519: commands include:
1.13 nicm 520: .Bd -literal -offset indent
1.57 jmc 521: refresh-client -t/dev/ttyp2

1.57 jmc 542: .Sh CLIENTS AND SESSIONS
1.153 nicm 543: The
544: .Nm
545: server manages clients, sessions, windows and panes.
546: Clients are attached to sessions to interact with them, either
547: when they are created with the
548: .Ic new-session
549: command, or later with the
550: .Ic attach-session
551: command.
1.188 nicm 552: Each session has one or more windows

3121: and are displayed in the status line and various lists: the name is the
3122: .Nm
3123: identifier for a window or session.
3124: Only panes have titles.
3125: A pane's title is typically set by the program running inside the pane and
3126: is not modified by
3127: .Nm .
3128: It is the same mechanism used to set for example the
3129: .Xr xterm 1
3130: window title in an

3132: window manager.
1.268 nicm 3133: Windows themselves do not have titles - a window's title is the title of its
