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.
1.1 nicm 417: .Pp
1.57 jmc 418: .Ar target-window
419: specifies a window in the form
420: .Em session Ns \&: Ns Em window .
421: .Em session
422: follows the same rules as for
423: .Ar target-session ,
424: and
425: .Em window
1.423 nicm 426: is looked for in order as:
427: .Bl -enum -offset Ds
428: .It
429: A special token, listed below.
430: .It
431: A window index, for example
432: .Ql mysession:1
433: is window 1 in session
434: .Ql mysession .
435: .It
436: A window ID, such as @1.
437: .It
438: An exact window name, such as
439: .Ql mysession:mywindow .
440: .It
441: The start of a window name, such as
442: .Ql mysession:mywin .
443: .It
444: As an
1.57 jmc 445: .Xr fnmatch 3
1.423 nicm 446: pattern matched against the window name.
447: .El
448: .Pp
1.435 nicm 449: Like sessions, a
450: .Ql =
451: prefix will do an exact match only.
1.57 jmc 452: An empty window name specifies the next unused index if appropriate (for
453: example the
454: .Ic new-window
455: and
456: .Ic link-window
457: commands)
458: otherwise the current window in
459: .Em session
460: is chosen.
1.423 nicm 461: .Pp
1.424 nicm 462: The following special tokens are available to indicate particular windows.
463: Each has a single-character alternative form.
1.423 nicm 464: .Bl -column "XXXXXXXXXX" "X"

1.57 jmc 476: .Ar target-window
1.423 nicm 477: but with the optional addition of a period followed by a pane index or pane ID,
478: for example:
479: .Ql mysession:mywindow.1 .
1.57 jmc 480: If the pane index is omitted, the currently active pane in the specified

2054: allows a command to be bound to most keys, with or without a prefix key.
2055: When specifying keys, most represent themselves (for example
2056: .Ql A
2057: to
1.95 jmc 2058: .Ql Z ) .
1.93 nicm 2059: Ctrl keys may be prefixed with
2060: .Ql C-
2061: or
1.95 jmc 2062: .Ql ^ ,
2063: and Alt (meta) with
1.93 nicm 2064: .Ql M- .
2065: In addition, the following special key names are accepted:
1.126 nicm 2066: .Em Up ,
2067: .Em Down ,
2068: .Em Left ,
2069: .Em Right ,
1.93 nicm 2070: .Em BSpace ,
2071: .Em BTab ,
2072: .Em DC
2073: (Delete),
2074: .Em End ,

2076: .Em Escape ,
2077: .Em F1
2078: to
1.402 nicm 2079: .Em F12 ,
1.93 nicm 2080: .Em Home ,

2084: .Em PPage/PageUp/PgUp ,
1.93 nicm 2085: .Em Space ,
2086: and
2087: .Em Tab .
2088: Note that to bind the
2089: .Ql \&"
2090: or
2091: .Ql '
2092: keys, quotation marks are necessary, for example:
2093: .Bd -literal -offset indent
2094: bind-key '"' split-window
1.167 nicm 2095: bind-key "'" new-window
1.93 nicm 2096: .Ed

2108: .Ar key
2109: to
2110: .Ar command .
1.421 nicm 2111: Keys are bound in a key table.
2112: By default (without -T), the key is bound in
2113: the
2114: .Em prefix
2115: key table.
2116: This table is used for keys pressed after the prefix key (for example,
2117: by default
2118: .Ql c
2119: is bound to
2120: .Ic new-window
2121: in the
2122: .Em prefix
2123: table, so
2124: .Ql C-b c
2125: creates a new window).
2126: The
2127: .Em root
2128: table is used for keys pressed without the prefix key: binding
2129: .Ql c
2130: to
2131: .Ic new-window
2132: in the
2133: .Em root
2134: table (not recommended) means a plain
2135: .Ql c
2136: will create a new window.
1.57 jmc 2137: .Fl n
1.421 nicm 2138: is an alias
2139: for

2141: Keys may also be bound in custom key tables and the
2142: .Ic switch-client
2143: .Fl T
2144: command used to switch to them from a key binding.
1.1 nicm 2145: The
1.57 jmc 2146: .Fl r
2147: flag indicates this key may repeat, see the
2148: .Ic repeat-time

2201: Send a key or keys to a window.
2202: Each argument
2203: .Ar key
2204: is the name of the key (such as
2205: .Ql C-a
2206: or
2207: .Ql npage
2208: ) to send; if the string is not recognised as a key, it is sent as a series of
2209: characters.
1.273 nicm 2210: The
2211: .Fl l
2212: flag disables key name lookup and sends the keys literally.
1.57 jmc 2213: All arguments are sent sequentially from first to last.
1.265 nicm 2214: The

1.57 jmc 2247: .El
2248: .Sh OPTIONS
2249: The appearance and behaviour of
2250: .Nm
2251: may be modified by changing the value of various options.
1.133 nicm 2252: There are three types of option:
2253: .Em server options ,
1.57 jmc 2254: .Em session options
2255: and
2256: .Em window options .
2257: .Pp
1.133 nicm 2258: The
2259: .Nm
2260: server has a set of global options which do not apply to any particular
2261: window or session.
2262: These are altered with the
2263: .Ic set-option
2264: .Fl s
2265: command, or displayed with the
2266: .Ic show-options
2267: .Fl s
2268: command.
2269: .Pp
2270: In addition, each individual session may have a set of session options, and
2271: there is a separate set of global session options.
1.57 jmc 2272: Sessions which do not have a particular option configured inherit the value
2273: from the global session options.
2274: Session options are set or unset with the
2275: .Ic set-option
2276: command and may be listed with the
2277: .Ic show-options
2278: command.
1.133 nicm 2279: The available server and session options are listed under the
1.57 jmc 2280: .Ic set-option
2281: command.
2282: .Pp
2283: Similarly, a set of window options is attached to each window, and there is
2284: a set of global window options from which any unset options are inherited.
2285: Window options are altered with the
2286: .Ic set-window-option
2287: command and can be listed with the
2288: .Ic show-window-options
2289: command.
2290: All window options are documented with the
2291: .Ic set-window-option
2292: command.
1.318 nicm 2293: .Pp
2294: .Nm
2295: also supports user options which are prefixed with a
2296: .Ql \&@ .
1.321 jmc 2297: User options may have any name, so long as they are prefixed with
2298: .Ql \&@ ,
1.318 nicm 2299: and be set to any string.
1.418 nicm 2300: For example:
1.318 nicm 2301: .Bd -literal -offset indent
2302: $ tmux setw -q @foo "abc123"
2303: $ tmux showw -v @foo
2304: abc123
2305: .Ed
1.57 jmc 2306: .Pp

2314: .D1 (alias: Ic set )
1.133 nicm 2315: Set a window option with
2316: .Fl w

2318: .Ic set-window-option
2319: command),
2320: a server option with
2321: .Fl s ,
2322: otherwise a session option.
2323: If
2324: .Fl g
1.433 nicm 2325: is given, the global session or window option is set.
1.1 nicm 2326: The
2327: .Fl u
2328: flag unsets an option, so a session inherits the option from the global
1.433 nicm 2329: options (or with
2330: .Fl g ,
2331: restores a global option to the default).
1.336 nicm 2332: .Pp
2333: The
2334: .Fl o
1.446 nicm 2335: flag prevents setting an option that is already set and the
1.281 nicm 2336: .Fl q
1.446 nicm 2337: flag suppresses errors about unknown or ambiguous options.
1.281 nicm 2338: .Pp
1.378 nicm 2339: With
2340: .Fl a ,
2341: and if the option expects a string or a style,
2342: .Ar value
2343: is appended to the existing setting.
2344: For example:
2345: .Bd -literal -offset indent
2346: set -g status-left "foo"
2347: set -ag status-left "bar"
2348: .Ed
2349: .Pp
2350: Will result in
2351: .Ql foobar .
2352: And:
2353: .Bd -literal -offset indent
2354: set -g status-style "bg=red"
2355: set -ag status-style "fg=blue"
2356: .Ed
2357: .Pp
2358: Will result in a red background
2359: .Em and
2360: blue foreground.
2361: Without
2362: .Fl a ,
2363: the result would be the default background and a blue foreground.
2364: .Pp
1.133 nicm 2365: Available window options are listed under
2366: .Ic set-window-option .
1.274 nicm 2367: .Pp
2368: .Ar value
2369: depends on the option and may be a number, a string, or a flag (on, off, or
2370: omitted to toggle).
1.133 nicm 2371: .Pp
2372: Available server options are:
2373: .Bl -tag -width Ds
1.198 nicm 2374: .It Ic buffer-limit Ar number
2375: Set the number of buffers; as new buffers are added to the top of the stack,

2379: Set the default terminal for new windows created in this session - the
2380: default value of the
2381: .Ev TERM
2382: environment variable.
2383: For
2384: .Nm
2385: to work correctly, this
2386: .Em must
2387: be set to

1.359 nicm 3262: .Ql #{session_name} .
1.409 nicm 3263: The possible variables are listed in the table below, or the name of a

3276: if the specified variable exists and is not zero, the first alternative
1.246 jmc 3277: is chosen, otherwise the second is used.
3278: For example
1.245 nicm 3279: .Ql #{?session_attached,attached,not attached}
3280: will include the string
3281: .Ql attached
3282: if the session is attached and the string

1.453 nicm 3293: .Pp
1.367 nicm 3294: A limit may be placed on the length of the resultant string by prefixing it
3295: by an
3296: .Ql = ,
3297: a number and a colon, so
3298: .Ql #{=10:pane_title}
3299: will include at most the first 10 characters of the pane title.
1.453 nicm 3300: Prefixing a time variable with
3301: .Ql t:
3302: will convert it to a string, so if
3303: .Ql #{window_activity}

1.454 jmc 3305: .Ql 1445765102 ,
1.453 nicm 3306: .Ql #{t:window_activity}

3309: The
3310: .Ql b:
3311: and
3312: .Ql d:
3313: prefixes are
3314: .Xr basename 3
3315: and

3317: of the variable respectively.
1.461 nicm 3318: A prefix of the form
3319: .Ql s/foo/bar/:

3324: throughout.
1.431 nicm 3325: .Pp
3326: In addition, the first line of a shell command's output may be inserted using
3327: .Ql #() .
3328: For example,

3330: will insert the system's uptime.
3331: When constructing formats,

3335: commands to finish; instead, the previous result from running the same command is used,

3443: Only panes have titles.
3444: A pane's title is typically set by the program running inside the pane and

1.268 nicm 3452: Windows themselves do not have titles - a window's title is the title of its
