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.
1.91 nicm 105: .It Fl c Ar shell-command
106: Execute
107: .Ar shell-command
108: using the default shell.
109: If necessary, the
110: .Nm
111: server will be started to retrieve the
112: .Ic default-shell
113: option.
1.153 nicm 114: This option is for compatibility with
115: .Xr sh 1
116: when
117: .Nm
118: is used as a login shell.
1.1 nicm 119: .It Fl f Ar file
120: Specify an alternative configuration file.
121: By default,
122: .Nm
1.26 nicm 123: loads the system configuration file from
124: .Pa /etc/tmux.conf ,
125: if present, then looks for a user configuration file at
1.1 nicm 126: .Pa ~/.tmux.conf .
127: The configuration file is a set of
128: .Nm
129: commands which are executed in sequence when the server is first started.
1.61 nicm 130: .Pp
131: If a command in the configuration file fails,
132: .Nm
133: will report an error and exit without executing further commands.
1.1 nicm 134: .It Fl L Ar socket-name
135: .Nm
136: stores the server socket in a directory under
137: .Pa /tmp ;
138: the default socket is named
139: .Em default .
140: This option allows a different socket name to be specified, allowing several
141: independent
142: .Nm
143: servers to be run.
144: Unlike
145: .Fl S
146: a full path is not necessary: the sockets are all created in the same
147: directory.
1.2 nicm 148: .Pp
149: If the socket is accidentally removed, the
1.6 jmc 150: .Dv SIGUSR1
1.2 nicm 151: signal may be sent to the
152: .Nm
153: server process to recreate it.
1.166 sobrado 154: .It Fl l
155: Behave as a login shell.
156: This flag currently has no effect and is for compatibility with other shells
157: when using tmux as a login shell.
1.4 sobrado 158: .It Fl q
1.133 nicm 159: Set the
160: .Ic quiet
161: server option to prevent the server sending various informational messages.
1.1 nicm 162: .It Fl S Ar socket-path
163: Specify a full alternative path to the server socket.
164: If
165: .Fl S
166: is specified, the default socket directory is not used and any
167: .Fl L
168: flag is ignored.
169: .It Fl u
170: .Nm
1.14 nicm 171: attempts to guess if the terminal is likely to support UTF-8 by checking the
172: first of the
173: .Ev LC_ALL ,
174: .Ev LC_CTYPE
175: and
1.2 nicm 176: .Ev LANG
1.14 nicm 177: environment variables to be set for the string "UTF-8".
1.5 nicm 178: This is not always correct: the
1.2 nicm 179: .Fl u
180: flag explicitly informs
181: .Nm
1.6 jmc 182: that UTF-8 is supported.
1.33 nicm 183: .Pp
184: If the server is started from a client passed
185: .Fl u
186: or where UTF-8 is detected, the
187: .Ic utf8
188: and
189: .Ic status-utf8
190: options are enabled in the global window and session options respectively.
1.1 nicm 191: .It Fl v
192: Request verbose logging.
193: This option may be specified multiple times for increasing verbosity.
194: Log messages will be saved into
195: .Pa tmux-client-PID.log
196: and
197: .Pa tmux-server-PID.log
198: files in the current directory, where
199: .Em PID
1.6 jmc 200: is the PID of the server or client process.
1.1 nicm 201: .It Ar command Op Ar flags
202: This specifies one of a set of commands used to control
203: .Nm ,
1.6 jmc 204: as described in the following sections.
1.59 jmc 205: If no commands are specified, the
1.1 nicm 206: .Ic new-session
207: command is assumed.
1.57 jmc 208: .El
1.64 nicm 209: .Sh KEY BINDINGS
210: .Nm

321: .Ic unbind-key
322: commands.
1.57 jmc 323: .Sh COMMANDS
324: This section contains a list of the commands supported by
325: .Nm .
326: Most commands accept the optional
327: .Fl t
328: argument with one of
329: .Ar target-client ,
330: .Ar target-session
331: .Ar target-window ,
332: or
333: .Ar target-pane .
334: These specify the client, session, window or pane which a command should affect.
335: .Ar target-client
336: is the name of the
337: .Xr pty 4
338: file to which the client is connected, for example either of
339: .Pa /dev/ttyp1
340: or
341: .Pa ttyp1
342: for the client attached to
343: .Pa /dev/ttyp1 .
344: If no client is specified, the current client is chosen, if possible, or an
345: error is reported.
346: Clients may be listed with the
347: .Ic list-clients
348: command.
1.1 nicm 349: .Pp
1.57 jmc 350: .Ar target-session
351: is either the name of a session (as listed by the
352: .Ic list-sessions
353: command) or the name of a client with the same syntax as
354: .Ar target-client ,
355: in which case the session attached to the client is used.
356: When looking for the session name,
357: .Nm
358: initially searches for an exact match; if none is found, the session names
359: are checked for any for which
360: .Ar target-session
361: is a prefix or for which it matches as an
362: .Xr fnmatch 3
363: pattern.
364: If a single match is found, it is used as the target session; multiple matches
365: produce an error.
366: If a session is omitted, the current session is used if available; if no
1.117 nicm 367: current session is available, the most recently used is chosen.
1.1 nicm 368: .Pp
1.57 jmc 369: .Ar target-window
370: specifies a window in the form
371: .Em session Ns \&: Ns Em window .
372: .Em session
373: follows the same rules as for
374: .Ar target-session ,
375: and
376: .Em window
377: is looked for in order: as a window index, for example mysession:1; as an exact
378: window name, such as mysession:mywindow; then as an
379: .Xr fnmatch 3
380: pattern or the start of a window name, such as mysession:mywin* or
381: mysession:mywin.
382: An empty window name specifies the next unused index if appropriate (for
383: example the
384: .Ic new-window
385: and
386: .Ic link-window
387: commands)
388: otherwise the current window in
389: .Em session
390: is chosen.
1.140 nicm 391: The special character
392: .Ql \&!
393: uses the last (previously current) window, or
394: .Ql +
395: and
396: .Ql -
397: are the next window or the previous window by number.
1.57 jmc 398: When the argument does not contain a colon,
399: .Nm
400: first attempts to parse it as window; if that fails, an attempt is made to
401: match a session.
1.1 nicm 402: .Pp
1.57 jmc 403: .Ar target-pane
404: takes a similar form to
405: .Ar target-window
406: but with the optional addition of a period followed by a pane index, for
407: example: mysession:mywindow.1.
408: If the pane index is omitted, the currently active pane in the specified
409: window is used.
410: If neither a colon nor period appears,
1.13 nicm 411: .Nm
1.57 jmc 412: first attempts to use the argument as a pane index; if that fails, it is looked
413: up as for
414: .Ar target-window .
1.156 nicm 415: A
416: .Ql +
417: or
418: .Ql -
419: indicate the next or previous pane index, respectively.
1.132 nicm 420: One of the strings
421: .Em top ,
422: .Em bottom ,
423: .Em left ,
424: .Em right ,
425: .Em top-left ,
426: .Em top-right ,
427: .Em bottom-left or
428: .Em bottom-right
429: may be used instead of a pane index.
1.177 ! nicm 430: .Pp
! 431: The special characters
! 432: .Ql +
! 433: and
! 434: .Ql -
! 435: may be followed by an offset, for example:
! 436: .Bd -literal -offset indent
! 437: select-window -t:+2
! 438: .Ed
! 439: .Pp
! 440: When dealing with a session that doesn't contain sequential window indexes,
! 441: they will be correctly skipped.
1.15 jmc 442: .Pp
1.153 nicm 443: .Ar shell-command
444: arguments are
445: .Xr sh 1
446: commands.
447: These must be passed as a single item, which typically means quoting them, for
448: example:
449: .Bd -literal -offset indent
450: new-window 'vi /etc/passwd'
451: .Ed
452: .Pp
453: .Ar command
454: .Op Ar arguments
455: refers to a
456: .Nm
457: command, passed with the command and arguments separately, for example:
458: .Bd -literal -offset indent
459: bind-key F1 set-window-option force-width 81
460: .Ed
461: .Pp
462: Or if using
463: .Xr sh 1 :
464: .Bd -literal -offset indent
465: $ tmux bind-key F1 set-window-option force-width 81
466: .Ed
467: .Pp
1.57 jmc 468: Multiple commands may be specified together as part of a
469: .Em command sequence .
470: Each command should be separated by spaces and a semicolon;
471: commands are executed sequentially from left to right.
472: A literal semicolon may be included by escaping it with a backslash (for
473: example, when specifying a command sequence to
474: .Ic bind-key ) .
1.13 nicm 475: .Pp
1.153 nicm 476: Example
477: .Nm
478: commands include:
1.13 nicm 479: .Bd -literal -offset indent
1.57 jmc 480: refresh-client -t/dev/ttyp2
481:
482: rename-session -tfirst newname

485:
486: new-window ; split-window -d
1.13 nicm 487: .Ed
1.153 nicm 488: .Pp
489: Or from

1.57 jmc 498: .Sh CLIENTS AND SESSIONS
1.153 nicm 499: The
500: .Nm
501: server manages clients, sessions, windows and panes.
502: Clients are attached to sessions to interact with them, either
503: when they are created with the
504: .Ic new-session
505: command, or later with the
506: .Ic attach-session
507: command.
508: Each session has one of more windows
509: .Em linked
510: into it.
511: Windows may be linked to multiple sessions and are made up of one or
512: more panes,
513: each of which contains a pseudo terminal.
514: Commands for creating, linking and otherwise manipulating windows
515: are covered
516: in the
