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 .
1.306 nicm 127: .Pp
1.1 nicm 128: The configuration file is a set of
129: .Nm
130: commands which are executed in sequence when the server is first started.
1.306 nicm 131: .Nm
132: loads configuration files once when the server process has started.
133: The
134: .Ic source-file
135: command may be used to load a file later.
1.61 nicm 136: .Pp
137: .Nm
1.306 nicm 138: shows any error messages from commands in configuration files in the first
139: session created, and continues to process the rest of the configuration file.
1.1 nicm 140: .It Fl L Ar socket-name
141: .Nm
142: stores the server socket in a directory under
1.208 nicm 143: .Pa /tmp
144: (or
145: .Ev TMPDIR
146: if set);
1.1 nicm 147: the default socket is named
148: .Em default .
149: This option allows a different socket name to be specified, allowing several
150: independent
151: .Nm
152: servers to be run.
153: Unlike
154: .Fl S
155: a full path is not necessary: the sockets are all created in the same
156: directory.
1.2 nicm 157: .Pp
158: If the socket is accidentally removed, the
1.6 jmc 159: .Dv SIGUSR1
1.2 nicm 160: signal may be sent to the
161: .Nm
162: server process to recreate it.
1.166 sobrado 163: .It Fl l
164: Behave as a login shell.
165: This flag currently has no effect and is for compatibility with other shells
166: when using tmux as a login shell.
1.4 sobrado 167: .It Fl q
1.133 nicm 168: Set the
169: .Ic quiet
170: server option to prevent the server sending various informational messages.
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:

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

1.57 jmc 533: .Sh CLIENTS AND SESSIONS
1.153 nicm 534: The
535: .Nm
536: server manages clients, sessions, windows and panes.
537: Clients are attached to sessions to interact with them, either
538: when they are created with the
539: .Ic new-session
540: command, or later with the
541: .Ic attach-session
542: command.
1.188 nicm 543: Each session has one or more windows
1.153 nicm 544: .Em linked
545: into it.
546: Windows may be linked to multiple sessions and are made up of one or
547: more panes,
548: each of which contains a pseudo terminal.
549: Commands for creating, linking and otherwise manipulating windows
550: are covered
551: in the
