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
1.208 nicm 137: .Pa /tmp
138: (or
139: .Ev TMPDIR
140: if set);
1.1 nicm 141: the default socket is named
142: .Em default .
143: This option allows a different socket name to be specified, allowing several
144: independent
145: .Nm
146: servers to be run.
147: Unlike
148: .Fl S
149: a full path is not necessary: the sockets are all created in the same
150: directory.
1.2 nicm 151: .Pp
152: If the socket is accidentally removed, the
1.6 jmc 153: .Dv SIGUSR1
1.2 nicm 154: signal may be sent to the
155: .Nm
156: server process to recreate it.
1.166 sobrado 157: .It Fl l
158: Behave as a login shell.
159: This flag currently has no effect and is for compatibility with other shells
160: when using tmux as a login shell.
1.4 sobrado 161: .It Fl q
1.133 nicm 162: Set the
163: .Ic quiet
164: server option to prevent the server sending various informational messages.
1.1 nicm 165: .It Fl S Ar socket-path
166: Specify a full alternative path to the server socket.
167: If
168: .Fl S
169: is specified, the default socket directory is not used and any
170: .Fl L
171: flag is ignored.
172: .It Fl u
173: .Nm
1.14 nicm 174: attempts to guess if the terminal is likely to support UTF-8 by checking the
175: first of the
176: .Ev LC_ALL ,
177: .Ev LC_CTYPE
178: and
1.2 nicm 179: .Ev LANG
1.14 nicm 180: environment variables to be set for the string "UTF-8".
1.5 nicm 181: This is not always correct: the
1.2 nicm 182: .Fl u
183: flag explicitly informs
184: .Nm
1.6 jmc 185: that UTF-8 is supported.
1.33 nicm 186: .Pp
187: If the server is started from a client passed
188: .Fl u
189: or where UTF-8 is detected, the
190: .Ic utf8
191: and
192: .Ic status-utf8
193: options are enabled in the global window and session options respectively.
1.1 nicm 194: .It Fl v
195: Request verbose logging.
196: This option may be specified multiple times for increasing verbosity.
197: Log messages will be saved into
198: .Pa tmux-client-PID.log
199: and
200: .Pa tmux-server-PID.log
201: files in the current directory, where
202: .Em PID
1.6 jmc 203: is the PID of the server or client process.
1.1 nicm 204: .It Ar command Op Ar flags
205: This specifies one of a set of commands used to control
206: .Nm ,
1.6 jmc 207: as described in the following sections.
1.59 jmc 208: If no commands are specified, the
1.1 nicm 209: .Ic new-session
210: command is assumed.
1.57 jmc 211: .El
1.64 nicm 212: .Sh KEY BINDINGS
213: .Nm

329: and
330: .Ic unbind-key
331: commands.
1.57 jmc 332: .Sh COMMANDS
333: This section contains a list of the commands supported by
334: .Nm .
335: Most commands accept the optional
336: .Fl t
337: argument with one of
338: .Ar target-client ,
339: .Ar target-session
340: .Ar target-window ,
341: or
342: .Ar target-pane .
343: These specify the client, session, window or pane which a command should affect.
344: .Ar target-client
345: is the name of the
346: .Xr pty 4
347: file to which the client is connected, for example either of
348: .Pa /dev/ttyp1
349: or
350: .Pa ttyp1
351: for the client attached to
352: .Pa /dev/ttyp1 .
353: If no client is specified, the current client is chosen, if possible, or an
354: error is reported.
355: Clients may be listed with the
356: .Ic list-clients
357: command.
1.1 nicm 358: .Pp
1.57 jmc 359: .Ar target-session
360: is either the name of a session (as listed by the
361: .Ic list-sessions
362: command) or the name of a client with the same syntax as
363: .Ar target-client ,
364: in which case the session attached to the client is used.
365: When looking for the session name,
366: .Nm
367: initially searches for an exact match; if none is found, the session names
368: are checked for any for which
369: .Ar target-session
370: is a prefix or for which it matches as an
371: .Xr fnmatch 3
372: pattern.
373: If a single match is found, it is used as the target session; multiple matches
374: produce an error.
375: If a session is omitted, the current session is used if available; if no
1.117 nicm 376: current session is available, the most recently used is chosen.
1.1 nicm 377: .Pp
1.57 jmc 378: .Ar target-window
379: specifies a window in the form
380: .Em session Ns \&: Ns Em window .
381: .Em session
382: follows the same rules as for
383: .Ar target-session ,
384: and
385: .Em window
386: is looked for in order: as a window index, for example mysession:1; as an exact
387: window name, such as mysession:mywindow; then as an
388: .Xr fnmatch 3
389: pattern or the start of a window name, such as mysession:mywin* or
390: mysession:mywin.
391: An empty window name specifies the next unused index if appropriate (for
392: example the
393: .Ic new-window
394: and
395: .Ic link-window
396: commands)
397: otherwise the current window in
398: .Em session
399: is chosen.
1.140 nicm 400: The special character
401: .Ql \&!
402: uses the last (previously current) window, or
403: .Ql +
404: and
405: .Ql -
406: are the next window or the previous window by number.
1.57 jmc 407: When the argument does not contain a colon,
408: .Nm
409: first attempts to parse it as window; if that fails, an attempt is made to
410: match a session.
1.1 nicm 411: .Pp
1.57 jmc 412: .Ar target-pane
413: takes a similar form to
414: .Ar target-window
415: but with the optional addition of a period followed by a pane index, for
416: example: mysession:mywindow.1.
417: If the pane index is omitted, the currently active pane in the specified
418: window is used.
419: If neither a colon nor period appears,
1.13 nicm 420: .Nm
1.57 jmc 421: first attempts to use the argument as a pane index; if that fails, it is looked
422: up as for
423: .Ar target-window .
1.156 nicm 424: A
425: .Ql +
426: or
427: .Ql -
428: indicate the next or previous pane index, respectively.
1.132 nicm 429: One of the strings
430: .Em top ,
431: .Em bottom ,
432: .Em left ,
433: .Em right ,
434: .Em top-left ,
435: .Em top-right ,
1.216 nicm 436: .Em bottom-left
437: or
1.132 nicm 438: .Em bottom-right
439: may be used instead of a pane index.
1.177 nicm 440: .Pp
441: The special characters
442: .Ql +
443: and
444: .Ql -
445: may be followed by an offset, for example:
446: .Bd -literal -offset indent
447: select-window -t:+2
448: .Ed
449: .Pp
450: When dealing with a session that doesn't contain sequential window indexes,
451: they will be correctly skipped.
1.212 nicm 452: .Pp
453: .Nm
454: also gives each pane created in a server an identifier consisting of a
455: .Ql %
456: and a number, starting from zero.
457: A pane's identifier is unique for the life of the
458: .Nm
459: server and is passed to the child process of the pane in the
460: .Ev TMUX_PANE
461: environment variable.
462: It may be used alone to target a pane or the window containing it.
1.15 jmc 463: .Pp
1.153 nicm 464: .Ar shell-command
465: arguments are
466: .Xr sh 1
467: commands.
468: These must be passed as a single item, which typically means quoting them, for
469: example:
470: .Bd -literal -offset indent
471: new-window 'vi /etc/passwd'
472: .Ed
473: .Pp
474: .Ar command
475: .Op Ar arguments
476: refers to a
477: .Nm
478: command, passed with the command and arguments separately, for example:
479: .Bd -literal -offset indent
480: bind-key F1 set-window-option force-width 81
481: .Ed
482: .Pp
483: Or if using
484: .Xr sh 1 :
485: .Bd -literal -offset indent
486: $ tmux bind-key F1 set-window-option force-width 81
487: .Ed
488: .Pp
1.57 jmc 489: Multiple commands may be specified together as part of a
490: .Em command sequence .
491: Each command should be separated by spaces and a semicolon;
492: commands are executed sequentially from left to right.
493: A literal semicolon may be included by escaping it with a backslash (for
494: example, when specifying a command sequence to
495: .Ic bind-key ) .
1.13 nicm 496: .Pp
1.153 nicm 497: Example
498: .Nm
499: commands include:
1.13 nicm 500: .Bd -literal -offset indent
1.57 jmc 501: refresh-client -t/dev/ttyp2
502:
503: rename-session -tfirst newname

506:
507: new-window ; split-window -d
1.13 nicm 508: .Ed
1.153 nicm 509: .Pp
510: Or from
511: .Xr sh 1 :

1.57 jmc 519: .Sh CLIENTS AND SESSIONS
1.153 nicm 520: The
521: .Nm
522: server manages clients, sessions, windows and panes.
523: Clients are attached to sessions to interact with them, either
524: when they are created with the
525: .Ic new-session
526: command, or later with the
527: .Ic attach-session
528: command.
1.188 nicm 529: Each session has one or more windows
1.153 nicm 530: .Em linked
531: into it.
532: Windows may be linked to multiple sessions and are made up of one or
533: more panes,
534: each of which contains a pseudo terminal.
535: Commands for creating, linking and otherwise manipulating windows
536: are covered
537: in the
538: .Sx WINDOWS AND PANES
539: section.
540: .Pp
541: The following commands are available to manage clients and sessions:
1.57 jmc 542: .Bl -tag -width Ds
543: .It Xo Ic attach-session
1.148 nicm 544: .Op Fl dr
1.57 jmc 545: .Op Fl t Ar target-session
546: .Xc
547: .D1 (alias: Ic attach )
548: If run from outside
549: .Nm ,
550: create a new client in the current terminal and attach it to
551: .Ar target-session .
552: If used from inside, switch the current client.
553: If
554: .Fl d
555: is specified, any other clients attached to the session are detached.
1.148 nicm 556: .Fl r
557: signifies the client is read-only (only keys bound to the
558: .Ic detach-client
559: command have any effect)
1.13 nicm 560: .Pp
1.57 jmc 561: If no server is started,
562: .Ic attach-session
