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

347: commands.
1.57 jmc 348: .Sh COMMANDS
349: This section contains a list of the commands supported by
350: .Nm .
351: Most commands accept the optional
352: .Fl t
353: argument with one of
354: .Ar target-client ,
355: .Ar target-session
356: .Ar target-window ,
357: or
358: .Ar target-pane .
359: These specify the client, session, window or pane which a command should affect.
360: .Ar target-client
361: is the name of the
362: .Xr pty 4
363: file to which the client is connected, for example either of
364: .Pa /dev/ttyp1
365: or
366: .Pa ttyp1
367: for the client attached to
368: .Pa /dev/ttyp1 .
369: If no client is specified, the current client is chosen, if possible, or an
370: error is reported.
371: Clients may be listed with the
372: .Ic list-clients
373: command.
1.1 nicm 374: .Pp
1.57 jmc 375: .Ar target-session
1.344 nicm 376: is the session id prefixed with a $, the name of a session (as listed by the
1.57 jmc 377: .Ic list-sessions
1.344 nicm 378: command), or the name of a client with the same syntax as
1.57 jmc 379: .Ar target-client ,
380: in which case the session attached to the client is used.
381: When looking for the session name,
382: .Nm
383: initially searches for an exact match; if none is found, the session names
384: are checked for any for which
385: .Ar target-session
386: is a prefix or for which it matches as an
387: .Xr fnmatch 3
388: pattern.
389: If a single match is found, it is used as the target session; multiple matches
390: produce an error.
391: If a session is omitted, the current session is used if available; if no
1.117 nicm 392: current session is available, the most recently used is chosen.
1.1 nicm 393: .Pp
1.57 jmc 394: .Ar target-window
395: specifies a window in the form
396: .Em session Ns \&: Ns Em window .
397: .Em session
398: follows the same rules as for
399: .Ar target-session ,
400: and
401: .Em window
1.270 nicm 402: is looked for in order: as a window index, for example mysession:1;
1.271 jmc 403: as a window ID, such as @1;
1.270 nicm 404: as an exact window name, such as mysession:mywindow; then as an
1.57 jmc 405: .Xr fnmatch 3
406: pattern or the start of a window name, such as mysession:mywin* or
407: mysession:mywin.
408: An empty window name specifies the next unused index if appropriate (for
409: example the
410: .Ic new-window
411: and
412: .Ic link-window
413: commands)
414: otherwise the current window in
415: .Em session
416: is chosen.
1.140 nicm 417: The special character
418: .Ql \&!
1.311 nicm 419: uses the last (previously current) window,
420: .Ql ^
421: selects the highest numbered window,
422: .Ql $
423: selects the lowest numbered window, and
1.140 nicm 424: .Ql +
425: and
426: .Ql -
1.311 nicm 427: select the next window or the previous window by number.
1.57 jmc 428: When the argument does not contain a colon,
429: .Nm
430: first attempts to parse it as window; if that fails, an attempt is made to
431: match a session.
1.1 nicm 432: .Pp
1.57 jmc 433: .Ar target-pane
434: takes a similar form to
435: .Ar target-window
436: but with the optional addition of a period followed by a pane index, for
437: example: mysession:mywindow.1.
438: If the pane index is omitted, the currently active pane in the specified
439: window is used.
440: If neither a colon nor period appears,
1.13 nicm 441: .Nm
1.57 jmc 442: first attempts to use the argument as a pane index; if that fails, it is looked
443: up as for
444: .Ar target-window .
1.156 nicm 445: A
1.401 nicm 446: .Ql + ,
447: .Ql -
1.156 nicm 448: or
1.401 nicm 449: .Ql \&!
450: indicate the next, previous or last pane.
1.132 nicm 451: One of the strings
452: .Em top ,
453: .Em bottom ,
454: .Em left ,
455: .Em right ,
456: .Em top-left ,
457: .Em top-right ,
1.216 nicm 458: .Em bottom-left
459: or
1.132 nicm 460: .Em bottom-right
461: may be used instead of a pane index.
1.177 nicm 462: .Pp
463: The special characters
464: .Ql +
465: and
466: .Ql -
467: may be followed by an offset, for example:
468: .Bd -literal -offset indent
469: select-window -t:+2
470: .Ed
471: .Pp
472: When dealing with a session that doesn't contain sequential window indexes,
473: they will be correctly skipped.
1.212 nicm 474: .Pp
475: .Nm
476: also gives each pane created in a server an identifier consisting of a
477: .Ql %
478: and a number, starting from zero.
479: A pane's identifier is unique for the life of the
480: .Nm
481: server and is passed to the child process of the pane in the
482: .Ev TMUX_PANE
483: environment variable.
484: It may be used alone to target a pane or the window containing it.
1.15 jmc 485: .Pp
1.153 nicm 486: .Ar shell-command
487: arguments are
488: .Xr sh 1
489: commands.
1.394 nicm 490: This may be a single argument passed to the shell, for example:
1.153 nicm 491: .Bd -literal -offset indent
492: new-window 'vi /etc/passwd'
493: .Ed
1.394 nicm 494: .Pp
495: Will run:
496: .Bd -literal -offset indent
497: /bin/sh -c 'vi /etc/passwd'
498: .Ed
499: .Pp
500: Additionally, the
501: .Ic new-window ,
502: .Ic new-session ,
503: .Ic split-window ,
504: .Ic respawn-window
505: and
506: .Ic respawn-pane
507: commands allow
508: .Ar shell-command
509: to be given as multiple arguments and executed directly (without
510: .Ql sh -c ) .
511: This can avoid issues with shell quoting.
512: For example:
513: .Bd -literal -offset indent
514: $ tmux new-window vi /etc/passwd
515: .Ed
516: .Pp
517: Will run
518: .Xr vi 1
519: directly without invoking the shell.
1.153 nicm 520: .Pp
521: .Ar command
522: .Op Ar arguments
523: refers to a
524: .Nm
525: command, passed with the command and arguments separately, for example:
526: .Bd -literal -offset indent
527: bind-key F1 set-window-option force-width 81
528: .Ed
529: .Pp
530: Or if using
531: .Xr sh 1 :
532: .Bd -literal -offset indent
533: $ tmux bind-key F1 set-window-option force-width 81
534: .Ed
535: .Pp
1.57 jmc 536: Multiple commands may be specified together as part of a
537: .Em command sequence .
538: Each command should be separated by spaces and a semicolon;
1.244 nicm 539: commands are executed sequentially from left to right and
1.293 nicm 540: lines ending with a backslash continue on to the next line,
541: except when escaped by another backslash.
1.57 jmc 542: A literal semicolon may be included by escaping it with a backslash (for
543: example, when specifying a command sequence to
544: .Ic bind-key ) .
1.13 nicm 545: .Pp
1.153 nicm 546: Example
547: .Nm
548: commands include:
1.13 nicm 549: .Bd -literal -offset indent
1.57 jmc 550: refresh-client -t/dev/ttyp2
551:
552: rename-session -tfirst newname

3183: .Nm
3184: identifier for a window or session.
3185: Only panes have titles.
3186: A pane's title is typically set by the program running inside the pane and
3187: is not modified by
3188: .Nm .
3189: It is the same mechanism used to set for example the
3190: .Xr xterm 1
3191: window title in an

3193: window manager.
1.268 nicm 3194: Windows themselves do not have titles - a window's title is the title of its

1.63 nicm 3244: .Pp
3245: The
