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
1.523 nicm 179: When starting,
1.1 nicm 180: .Nm
1.523 nicm 181: looks for the
1.14 nicm 182: .Ev LC_ALL ,
183: .Ev LC_CTYPE
184: and
1.2 nicm 185: .Ev LANG
1.523 nicm 186: environment variables: if the first found contains
187: .Ql UTF-8 ,
188: then the terminal is assumed to support UTF-8.
1.5 nicm 189: This is not always correct: the
1.2 nicm 190: .Fl u
191: flag explicitly informs
192: .Nm
1.6 jmc 193: that UTF-8 is supported.
1.33 nicm 194: .Pp
1.458 nicm 195: Note that
196: .Nm
1.459 jmc 197: itself always accepts UTF-8; this controls whether it will send UTF-8
198: characters to the terminal it is running (if not, they are replaced by
1.458 nicm 199: .Ql _ ) .
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:

1.57 jmc 354: .Sh COMMANDS
355: This section contains a list of the commands supported by
356: .Nm .
357: Most commands accept the optional
358: .Fl t
1.432 nicm 359: (and sometimes
360: .Fl s )
1.57 jmc 361: argument with one of
362: .Ar target-client ,
363: .Ar target-session
364: .Ar target-window ,
365: or
366: .Ar target-pane .
367: These specify the client, session, window or pane which a command should affect.
1.423 nicm 368: .Pp
1.57 jmc 369: .Ar target-client
1.540 nicm 370: should be the name of the client,
371: typically the
1.57 jmc 372: .Xr pty 4
373: file to which the client is connected, for example either of
374: .Pa /dev/ttyp1
375: or
376: .Pa ttyp1
377: for the client attached to
378: .Pa /dev/ttyp1 .
1.423 nicm 379: If no client is specified,
380: .Nm
381: attempts to work out the client currently in use; if that fails, an error is
382: reported.
1.57 jmc 383: Clients may be listed with the
384: .Ic list-clients
385: command.
1.1 nicm 386: .Pp
1.57 jmc 387: .Ar target-session
1.423 nicm 388: is tried as, in order:
389: .Bl -enum -offset Ds
390: .It
391: A session ID prefixed with a $.
392: .It
393: An exact name of a session (as listed by the
1.57 jmc 394: .Ic list-sessions
1.423 nicm 395: command).
396: .It
397: The start of a session name, for example
398: .Ql mysess
399: would match a session named
400: .Ql mysession .
401: .It
402: An
1.57 jmc 403: .Xr fnmatch 3
1.423 nicm 404: pattern which is matched against the session name.
405: .El
406: .Pp
1.441 nicm 407: If the session name is prefixed with an
408: .Ql = ,
1.435 nicm 409: only an exact match is accepted (so
410: .Ql =mysess
411: will only match exactly
412: .Ql mysess ,
413: not
414: .Ql mysession ) .
1.441 nicm 415: .Pp
1.423 nicm 416: If a single session is found, it is used as the target session; multiple matches
1.57 jmc 417: produce an error.
418: If a session is omitted, the current session is used if available; if no
1.117 nicm 419: current session is available, the most recently used is chosen.
1.1 nicm 420: .Pp

1.57 jmc 426: specifies a window in the form
427: .Em session Ns \&: Ns Em window .

429: follows the same rules as for
430: .Ar target-session ,
431: and
432: .Em window
1.423 nicm 433: is looked for in order as:
434: .Bl -enum -offset Ds
435: .It
436: A special token, listed below.
437: .It
438: A window index, for example
439: .Ql mysession:1
440: is window 1 in session
441: .Ql mysession .
442: .It
443: A window ID, such as @1.
444: .It
445: An exact window name, such as
446: .Ql mysession:mywindow .
447: .It
448: The start of a window name, such as
449: .Ql mysession:mywin .
450: .It
451: As an
1.57 jmc 452: .Xr fnmatch 3
1.423 nicm 453: pattern matched against the window name.
454: .El
455: .Pp
1.435 nicm 456: Like sessions, a
457: .Ql =
458: prefix will do an exact match only.
1.57 jmc 459: An empty window name specifies the next unused index if appropriate (for
460: example the
461: .Ic new-window
462: and
463: .Ic link-window
464: commands)
465: otherwise the current window in
466: .Em session
467: is chosen.
1.423 nicm 468: .Pp
1.424 nicm 469: The following special tokens are available to indicate particular windows.
470: Each has a single-character alternative form.
1.423 nicm 471: .Bl -column "XXXXXXXXXX" "X"

1.423 nicm 487: but with the optional addition of a period followed by a pane index or pane ID,
488: for example:
489: .Ql mysession:mywindow.1 .
1.57 jmc 490: If the pane index is omitted, the currently active pane in the specified
491: window is used.
1.423 nicm 492: The following special tokens are available for the pane index:
493: .Bl -column "XXXXXXXXXXXXXX" "X"
494: .It Sy "Token" Ta Sy "" Ta Sy "Meaning"

2279: and
2280: .Em window options .
2281: .Pp
1.133 nicm 2282: The

2284: server has a set of global options which do not apply to any particular
2285: window or session.
2286: These are altered with the
2287: .Ic set-option
2288: .Fl s
2289: command, or displayed with the
2290: .Ic show-options
2291: .Fl s
2292: command.
2293: .Pp
2294: In addition, each individual session may have a set of session options, and
2295: there is a separate set of global session options.
1.57 jmc 2296: Sessions which do not have a particular option configured inherit the value
2297: from the global session options.
2298: Session options are set or unset with the
2299: .Ic set-option
2300: command and may be listed with the
2301: .Ic show-options
2302: command.
1.133 nicm 2303: The available server and session options are listed under the
1.57 jmc 2304: .Ic set-option
2305: command.
2306: .Pp
2307: Similarly, a set of window options is attached to each window, and there is
2308: a set of global window options from which any unset options are inherited.
2309: Window options are altered with the
2310: .Ic set-window-option
2311: command and can be listed with the
2312: .Ic show-window-options
2313: command.

2346: otherwise a session option.
2347: If
2348: .Fl g
1.433 nicm 2349: is given, the global session or window option is set.
1.1 nicm 2350: The
2351: .Fl u
2352: flag unsets an option, so a session inherits the option from the global
1.433 nicm 2353: options (or with
2354: .Fl g ,
2355: restores a global option to the default).
1.336 nicm 2356: .Pp
2357: The
2358: .Fl o
1.446 nicm 2359: flag prevents setting an option that is already set and the
1.281 nicm 2360: .Fl q
1.446 nicm 2361: flag suppresses errors about unknown or ambiguous options.
1.281 nicm 2362: .Pp
1.378 nicm 2363: With
2364: .Fl a ,
2365: and if the option expects a string or a style,
2366: .Ar value
2367: is appended to the existing setting.
2368: For example:
2369: .Bd -literal -offset indent
2370: set -g status-left "foo"
2371: set -ag status-left "bar"
2372: .Ed
2373: .Pp
2374: Will result in

2377: .Bd -literal -offset indent
2378: set -g status-style "bg=red"
2379: set -ag status-style "fg=blue"
2380: .Ed
2381: .Pp
2382: Will result in a red background
2383: .Em and
2384: blue foreground.
2385: Without
2386: .Fl a ,
2387: the result would be the default background and a blue foreground.
2388: .Pp
1.133 nicm 2389: Available window options are listed under

1.274 nicm 2391: .Pp
2392: .Ar value

2396: Available server options are:
2397: .Bl -tag -width Ds
1.198 nicm 2398: .It Ic buffer-limit Ar number
2399: Set the number of buffers; as new buffers are added to the top of the stack,

2401: length.
1.526 nicm 2402: .It Xo Ic command-alias[]
2403: .Ar name=value
2404: .Xc
2405: This is an array of custom aliases for commands.
2406: If an unknown command matches
2407: .Ar name ,
2408: it is replaced with
2409: .Ar value .
2410: For example, after:
2411: .Pp
2412: .Dl set -s command-alias[2] zoom='resize-pane -Z'
2413: .Pp
2414: Using:
2415: .Pp
2416: .Dl zoom -t:.1
2417: .Pp
2418: Is equivalent to:
2419: .Pp
2420: .Dl resize-pane -Z -t:.1
2421: .Pp
2422: Note that aliases are expanded when a command is parsed rather than when it is
2423: executed, so binding an alias with
2424: .Ic bind-key
2425: will bind the expanded form.
1.425 nicm 2426: .It Ic default-terminal Ar terminal
2427: Set the default terminal for new windows created in this session - the

3375: binding).
3376: .Pp
3377: The

3394: Replacement variables are enclosed in
3395: .Ql #{
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 # .
1.409 nicm 3409: .Pp
3410: Conditionals are available by prefixing with
1.246 jmc 3411: .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}
3417: will include the string
3418: .Ql attached
3419: if the session is attached and the string
3420: .Ql not attached
1.409 nicm 3421: if it is unattached, or

3423: will include
3424: .Ql yes
3425: if

3427: is enabled, or
3428: .Ql no
3429: if not.
1.520 nicm 3430: .Pp
3431: Simple comparisons may be expressed by prefixing two comma-separated
3432: alternatives by
3433: .Ql ==
3434: or
3435: .Ql !=
3436: and a colon.
3437: For example
3438: .Ql #{==,#{host},myhost}
3439: will be replaced by
3440: .Ql 1
3441: if running on
3442: .Ql myhost ,
3443: otherwise by
3444: .Ql 0.
1.453 nicm 3445: .Pp
1.367 nicm 3446: A limit may be placed on the length of the resultant string by prefixing it
3447: by an
3448: .Ql = ,
1.479 nicm 3449: a number and a colon.
3450: Positive numbers count from the start of the string and negative from the end,
3451: so
3452: .Ql #{=5:pane_title}
3453: will include at most the first 5 characters of the pane title, or
3454: .Ql #{=-5:pane_title}
3455: the last 5 characters.
1.453 nicm 3456: Prefixing a time variable with
3457: .Ql t:
3458: will convert it to a string, so if
3459: .Ql #{window_activity}
3460: gives
1.454 jmc 3461: .Ql 1445765102 ,
1.453 nicm 3462: .Ql #{t:window_activity}
3463: gives
3464: .Ql Sun Oct 25 09:25:02 2015 .
3465: The
3466: .Ql b:
3467: and
3468: .Ql d:
3469: prefixes are
3470: .Xr basename 3
3471: and
3472: .Xr dirname 3
3473: of the variable respectively.
1.461 nicm 3474: A prefix of the form
3475: .Ql s/foo/bar/:
3476: will substitute
3477: .Ql foo
3478: with
3479: .Ql bar
3480: throughout.
1.431 nicm 3481: .Pp
3482: In addition, the first line of a shell command's output may be inserted using
3483: .Ql #() .
3484: For example,
3485: .Ql #(uptime)
3486: will insert the system's uptime.
3487: When constructing formats,
3488: .Nm
3489: does not wait for
3490: .Ql #()
3491: commands to finish; instead, the previous result from running the same command is used,
3492: or a placeholder if the command has not been run before.
3493: Commands are executed with the

3611: .Nm
3612: distinguishes between names and titles.
3613: Windows and sessions have names, which may be used to specify them in targets
3614: and are displayed in the status line and various lists: the name is the
3615: .Nm
3616: identifier for a window or session.
3617: Only panes have titles.
3618: A pane's title is typically set by the program running inside the pane and
3619: is not modified by
3620: .Nm .
3621: It is the same mechanism used to set for example the
3622: .Xr xterm 1
3623: window title in an

3625: window manager.
1.268 nicm 3626: Windows themselves do not have titles - a window's title is the title of its
1.261 nicm 3627: active pane.
3628: .Nm

1.63 nicm 3676: .Pp
3677: The
