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
1.455 nicm 146: .Ev TMUX_TMPDIR
147: or
1.208 nicm 148: .Pa /tmp
1.455 nicm 149: if it is unset.
1.355 nicm 150: The default socket is named
1.1 nicm 151: .Em default .
152: This option allows a different socket name to be specified, allowing several
153: independent
154: .Nm
155: servers to be run.
156: Unlike
157: .Fl S
158: a full path is not necessary: the sockets are all created in the same
159: directory.
1.2 nicm 160: .Pp
161: If the socket is accidentally removed, the
1.6 jmc 162: .Dv SIGUSR1
1.2 nicm 163: signal may be sent to the
164: .Nm
1.422 nicm 165: server process to recreate it (note that this will fail if any parent
166: directories are missing).
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
1.458 nicm 193: Note that
194: .Nm
1.459 jmc 195: itself always accepts UTF-8; this controls whether it will send UTF-8
196: characters to the terminal it is running (if not, they are replaced by
1.458 nicm 197: .Ql _ ) .
1.1 nicm 198: .It Fl v
199: Request verbose logging.
200: This option may be specified multiple times for increasing verbosity.
201: Log messages will be saved into
202: .Pa tmux-client-PID.log
203: and
204: .Pa tmux-server-PID.log
205: files in the current directory, where
206: .Em PID
1.6 jmc 207: is the PID of the server or client process.
1.1 nicm 208: .It Ar command Op Ar flags
209: This specifies one of a set of commands used to control
210: .Nm ,
1.6 jmc 211: as described in the following sections.
1.59 jmc 212: If no commands are specified, the
1.1 nicm 213: .Ic new-session
214: command is assumed.
1.57 jmc 215: .El
1.64 nicm 216: .Sh KEY BINDINGS

218: may be controlled from an attached client by using a key combination of a
219: prefix key,
220: .Ql C-b
221: (Ctrl-b) by default, followed by a command key.
222: .Pp
1.172 nicm 223: The default command key bindings are:

1.57 jmc 352: .Sh COMMANDS
353: This section contains a list of the commands supported by
354: .Nm .
355: Most commands accept the optional
356: .Fl t
1.432 nicm 357: (and sometimes
358: .Fl s )
1.57 jmc 359: argument with one of
360: .Ar target-client ,
361: .Ar target-session
362: .Ar target-window ,
363: or
364: .Ar target-pane .
365: These specify the client, session, window or pane which a command should affect.
1.423 nicm 366: .Pp
1.57 jmc 367: .Ar target-client
1.423 nicm 368: should be the name of the
1.57 jmc 369: .Xr pty 4
370: file to which the client is connected, for example either of
371: .Pa /dev/ttyp1
372: or
373: .Pa ttyp1
374: for the client attached to
375: .Pa /dev/ttyp1 .
1.423 nicm 376: If no client is specified,
377: .Nm
378: attempts to work out the client currently in use; if that fails, an error is
379: reported.
1.57 jmc 380: Clients may be listed with the
381: .Ic list-clients
382: command.
1.1 nicm 383: .Pp
1.57 jmc 384: .Ar target-session
1.423 nicm 385: is tried as, in order:
386: .Bl -enum -offset Ds
387: .It
388: A session ID prefixed with a $.
389: .It
390: An exact name of a session (as listed by the
1.57 jmc 391: .Ic list-sessions
1.423 nicm 392: command).
393: .It
394: The start of a session name, for example
395: .Ql mysess
396: would match a session named
397: .Ql mysession .
398: .It
399: An
1.57 jmc 400: .Xr fnmatch 3
1.423 nicm 401: pattern which is matched against the session name.
402: .El
403: .Pp
1.441 nicm 404: If the session name is prefixed with an
405: .Ql = ,
1.435 nicm 406: only an exact match is accepted (so
407: .Ql =mysess
408: will only match exactly
409: .Ql mysess ,
410: not
411: .Ql mysession ) .
1.441 nicm 412: .Pp
1.423 nicm 413: If a single session is found, it is used as the target session; multiple matches
1.57 jmc 414: produce an error.
415: If a session is omitted, the current session is used if available; if no
1.117 nicm 416: current session is available, the most recently used is chosen.

1.423 nicm 430: is looked for in order as:
431: .Bl -enum -offset Ds
432: .It
433: A special token, listed below.
434: .It
435: A window index, for example
436: .Ql mysession:1

438: .Ql mysession .
439: .It
440: A window ID, such as @1.
441: .It
442: An exact window name, such as

444: .It
445: The start of a window name, such as
446: .Ql mysession:mywin .
447: .It
448: As an

1.423 nicm 450: pattern matched against the window name.
451: .El
452: .Pp
1.435 nicm 453: Like sessions, a
454: .Ql =
455: prefix will do an exact match only.
1.57 jmc 456: An empty window name specifies the next unused index if appropriate (for
457: example the
458: .Ic new-window
459: and
460: .Ic link-window
461: commands)
462: otherwise the current window in

2284: .Pp
1.133 nicm 2285: The

2287: server has a set of global options which do not apply to any particular
2288: window or session.
2289: These are altered with the
2290: .Ic set-option
2291: .Fl s
2292: command, or displayed with the
2293: .Ic show-options
2294: .Fl s
2295: command.
2296: .Pp
2297: In addition, each individual session may have a set of session options, and
2298: there is a separate set of global session options.
1.57 jmc 2299: Sessions which do not have a particular option configured inherit the value
2300: from the global session options.
2301: Session options are set or unset with the
2302: .Ic set-option
2303: command and may be listed with the
2304: .Ic show-options
2305: command.
1.133 nicm 2306: The available server and session options are listed under the
1.57 jmc 2307: .Ic set-option
2308: command.
2309: .Pp
2310: Similarly, a set of window options is attached to each window, and there is
2311: a set of global window options from which any unset options are inherited.
2312: Window options are altered with the
2313: .Ic set-window-option
2314: command and can be listed with the
2315: .Ic show-window-options
2316: command.
2317: All window options are documented with the

2349: otherwise a session option.
2350: If
2351: .Fl g
1.433 nicm 2352: is given, the global session or window option is set.
1.1 nicm 2353: The
2354: .Fl u

1.433 nicm 2356: options (or with
2357: .Fl g ,
2358: restores a global option to the default).
1.336 nicm 2359: .Pp
2360: The

1.446 nicm 2362: flag prevents setting an option that is already set and the
1.281 nicm 2363: .Fl q
1.446 nicm 2364: flag suppresses errors about unknown or ambiguous options.
1.281 nicm 2365: .Pp
1.378 nicm 2366: With
2367: .Fl a ,
2368: and if the option expects a string or a style,
2369: .Ar value
2370: is appended to the existing setting.
2371: For example:
2372: .Bd -literal -offset indent
2373: set -g status-left "foo"
2374: set -ag status-left "bar"
2375: .Ed
2376: .Pp

3376: .Pp
3377: The
3378: .Ic send-keys
3379: .Fl M
3380: flag may be used to forward a mouse event to a pane.
3381: .Pp
3382: The default key bindings allow the mouse to be used to select and resize panes,
3383: to copy text and to change window using the status line.
3384: These take effect if the
3385: .Ic mouse
3386: option is turned on.
1.245 nicm 3387: .Sh FORMATS
1.294 nicm 3388: Certain commands accept the

3392: argument.
3393: This is a string which controls the output format of the command.
3394: Replacement variables are enclosed in

3396: and
3397: .Ql } ,
3398: for example
1.359 nicm 3399: .Ql #{session_name} .
1.409 nicm 3400: The possible variables are listed in the table below, or the name of a
3401: .Nm
3402: option may be used for an option's value.
3403: Some variables have a shorter alias such as
3404: .Ql #S ,
3405: and
1.376 nicm 3406: .Ql ##
3407: is replaced by a single
3408: .Ql # .

1.245 nicm 3412: and separating two alternatives with a comma;
3413: if the specified variable exists and is not zero, the first alternative
1.246 jmc 3414: is chosen, otherwise the second is used.
3415: For example
1.245 nicm 3416: .Ql #{?session_attached,attached,not attached}

3418: .Ql attached
3419: if the session is attached and the string

3428: .Ql no
3429: if not.
1.453 nicm 3430: .Pp
1.367 nicm 3431: A limit may be placed on the length of the resultant string by prefixing it
3432: by an
3433: .Ql = ,
1.479 nicm 3434: a number and a colon.
3435: Positive numbers count from the start of the string and negative from the end,
3436: so
3437: .Ql #{=5:pane_title}
3438: will include at most the first 5 characters of the pane title, or
3439: .Ql #{=-5:pane_title}
3440: the last 5 characters.
1.453 nicm 3441: Prefixing a time variable with
3442: .Ql t:
3443: will convert it to a string, so if
3444: .Ql #{window_activity}

1.454 jmc 3446: .Ql 1445765102 ,
1.453 nicm 3447: .Ql #{t:window_activity}

3450: The

3452: and
3453: .Ql d:
3454: prefixes are
3455: .Xr basename 3
3456: and

3458: of the variable respectively.
1.461 nicm 3459: A prefix of the form
3460: .Ql s/foo/bar/:
3461: will substitute
3462: .Ql foo
3463: with
3464: .Ql bar
3465: throughout.
1.431 nicm 3466: .Pp
3467: In addition, the first line of a shell command's output may be inserted using
3468: .Ql #() .
3469: For example,
3470: .Ql #(uptime)
3471: will insert the system's uptime.
3472: When constructing formats,
3473: .Nm
3474: does not wait for
3475: .Ql #()
3476: commands to finish; instead, the previous result from running the same command is used,

3591: .Nm
3592: identifier for a window or session.
3593: Only panes have titles.
3594: A pane's title is typically set by the program running inside the pane and
3595: is not modified by
3596: .Nm .
3597: It is the same mechanism used to set for example the
