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: Log messages will be saved into
203: .Pa tmux-client-PID.log
204: and
205: .Pa tmux-server-PID.log
206: files in the current directory, where
207: .Em PID
1.6 jmc 208: is the PID of the server or client process.
1.558 nicm 209: .Pp
210: If
211: .Fl v
212: is specified twice, an additional
213: .Pa tmux-out-PID.log
214: file is generated with a copy of everything
215: .Nm
216: writes to the terminal.
217: .Pp
218: The
219: .Dv SIGUSR2
220: signal may be sent to the
221: .Nm
222: server process to toggle logging between on (as if
223: .Fl v
224: was given) and off.
1.1 nicm 225: .It Ar command Op Ar flags
226: This specifies one of a set of commands used to control
227: .Nm ,
1.6 jmc 228: as described in the following sections.
1.59 jmc 229: If no commands are specified, the
1.1 nicm 230: .Ic new-session
231: command is assumed.
1.57 jmc 232: .El
1.64 nicm 233: .Sh KEY BINDINGS
234: .Nm
235: may be controlled from an attached client by using a key combination of a
236: prefix key,
237: .Ql C-b
238: (Ctrl-b) by default, followed by a command key.
239: .Pp
1.172 nicm 240: The default command key bindings are:

1.57 jmc 369: .Sh COMMANDS
370: This section contains a list of the commands supported by
371: .Nm .
372: Most commands accept the optional
373: .Fl t
1.432 nicm 374: (and sometimes
375: .Fl s )
1.57 jmc 376: argument with one of
377: .Ar target-client ,
378: .Ar target-session
379: .Ar target-window ,
380: or
381: .Ar target-pane .
382: These specify the client, session, window or pane which a command should affect.
1.423 nicm 383: .Pp
1.57 jmc 384: .Ar target-client
1.540 nicm 385: should be the name of the client,
386: typically the
1.57 jmc 387: .Xr pty 4
388: file to which the client is connected, for example either of
389: .Pa /dev/ttyp1
390: or
391: .Pa ttyp1
392: for the client attached to
393: .Pa /dev/ttyp1 .
1.423 nicm 394: If no client is specified,
395: .Nm
396: attempts to work out the client currently in use; if that fails, an error is
397: reported.
1.57 jmc 398: Clients may be listed with the
399: .Ic list-clients
400: command.
1.1 nicm 401: .Pp
1.57 jmc 402: .Ar target-session
1.423 nicm 403: is tried as, in order:
404: .Bl -enum -offset Ds
405: .It
406: A session ID prefixed with a $.
407: .It
408: An exact name of a session (as listed by the
1.57 jmc 409: .Ic list-sessions
1.423 nicm 410: command).
411: .It
412: The start of a session name, for example
413: .Ql mysess
414: would match a session named
415: .Ql mysession .
416: .It
417: An
1.57 jmc 418: .Xr fnmatch 3
1.423 nicm 419: pattern which is matched against the session name.
420: .El
421: .Pp
1.441 nicm 422: If the session name is prefixed with an
423: .Ql = ,
1.435 nicm 424: only an exact match is accepted (so
425: .Ql =mysess
426: will only match exactly
427: .Ql mysess ,
428: not
429: .Ql mysession ) .
1.441 nicm 430: .Pp
1.423 nicm 431: If a single session is found, it is used as the target session; multiple matches
1.57 jmc 432: produce an error.
433: If a session is omitted, the current session is used if available; if no
1.117 nicm 434: current session is available, the most recently used is chosen.
1.1 nicm 435: .Pp
1.57 jmc 436: .Ar target-window
1.472 nicm 437: (or
438: .Ar src-window
439: or
440: .Ar dst-window )
1.57 jmc 441: specifies a window in the form
442: .Em session Ns \&: Ns Em window .
443: .Em session
444: follows the same rules as for
445: .Ar target-session ,
446: and
447: .Em window
1.423 nicm 448: is looked for in order as:
449: .Bl -enum -offset Ds
450: .It
451: A special token, listed below.
452: .It
453: A window index, for example
454: .Ql mysession:1
455: is window 1 in session
456: .Ql mysession .
457: .It
458: A window ID, such as @1.
459: .It
460: An exact window name, such as
461: .Ql mysession:mywindow .
462: .It
463: The start of a window name, such as
464: .Ql mysession:mywin .
465: .It
466: As an
1.57 jmc 467: .Xr fnmatch 3
1.423 nicm 468: pattern matched against the window name.
469: .El
470: .Pp
1.435 nicm 471: Like sessions, a
472: .Ql =
473: prefix will do an exact match only.
1.57 jmc 474: An empty window name specifies the next unused index if appropriate (for
475: example the
476: .Ic new-window
477: and
478: .Ic link-window
479: commands)
480: otherwise the current window in
481: .Em session
482: is chosen.
1.423 nicm 483: .Pp
1.424 nicm 484: The following special tokens are available to indicate particular windows.
485: Each has a single-character alternative form.
1.423 nicm 486: .Bl -column "XXXXXXXXXX" "X"
487: .It Sy "Token" Ta Sy "" Ta Sy "Meaning"
488: .It Li "{start}" Ta "^" Ta "The lowest-numbered window"

1.472 nicm 496: (or
497: .Ar src-pane
498: or
499: .Ar dst-pane )
500: may be a pane ID or takes a similar form to
1.57 jmc 501: .Ar target-window
1.423 nicm 502: but with the optional addition of a period followed by a pane index or pane ID,
503: for example:
504: .Ql mysession:mywindow.1 .
1.57 jmc 505: If the pane index is omitted, the currently active pane in the specified
506: window is used.
1.423 nicm 507: The following special tokens are available for the pane index:
508: .Bl -column "XXXXXXXXXXXXXX" "X"
509: .It Sy "Token" Ta Sy "" Ta Sy "Meaning"

1.154 nicm 1171: .Ql _
1.146 nicm 1172: and
1173: .Ql @
1.154 nicm 1174: characters as word delimiters by default, but this can be adjusted by
1175: setting the

1.146 nicm 1178: Next word moves to the start of the next word, next word end to the end of the
1179: next word and previous word to the start of the previous word.
1180: The three next and previous space keys work similarly but use a space alone as
1181: the word separator.
1.157 nicm 1182: .Pp
1183: The jump commands enable quick movement within a line.
1184: For instance, typing
1185: .Ql f
1186: followed by

1216: should exit copy mode.
1217: While in copy mode, pressing a key other than those used for scrolling will
1218: disable this behaviour.
1219: This is intended to allow fast scrolling through a pane's history, for
1220: example with:

1.133 nicm 2345: The

2354: .Fl s
2355: command.
2356: .Pp
2357: In addition, each individual session may have a set of session options, and
2358: there is a separate set of global session options.
1.57 jmc 2359: Sessions which do not have a particular option configured inherit the value
2360: from the global session options.
2361: Session options are set or unset with the
2362: .Ic set-option
2363: command and may be listed with the
2364: .Ic show-options
2365: command.
1.133 nicm 2366: The available server and session options are listed under the
1.57 jmc 2367: .Ic set-option
2368: command.
2369: .Pp
2370: Similarly, a set of window options is attached to each window, and there is
2371: a set of global window options from which any unset options are inherited.
2372: Window options are altered with the
2373: .Ic set-window-option
2374: command and can be listed with the
2375: .Ic show-window-options

1.433 nicm 2412: is given, the global session or window option is set.
1.550 nicm 2413: .Fl F
2414: expands formats in the option value.
1.1 nicm 2415: The
2416: .Fl u

1.433 nicm 2418: options (or with
2419: .Fl g ,
2420: restores a global option to the default).
1.336 nicm 2421: .Pp
2422: The

1.446 nicm 2424: flag prevents setting an option that is already set and the
1.281 nicm 2425: .Fl q
1.446 nicm 2426: flag suppresses errors about unknown or ambiguous options.
1.281 nicm 2427: .Pp
1.378 nicm 2428: With
2429: .Fl a ,
2430: and if the option expects a string or a style,
2431: .Ar value

2435: set -g status-left "foo"
2436: set -ag status-left "bar"
2437: .Ed
2438: .Pp

2444: set -ag status-style "fg=blue"
2445: .Ed

1.198 nicm 2463: .It Ic buffer-limit Ar number
2464: Set the number of buffers; as new buffers are added to the top of the stack,

2466: length.
1.526 nicm 2467: .It Xo Ic command-alias[]
2468: .Ar name=value
2469: .Xc
2470: This is an array of custom aliases for commands.
2471: If an unknown command matches
2472: .Ar name ,
2473: it is replaced with
2474: .Ar value .
2475: For example, after:
2476: .Pp
1.565 nicm 2477: .Dl set -s command-alias[100] zoom='resize-pane -Z'
1.526 nicm 2478: .Pp
2479: Using:
2480: .Pp
2481: .Dl zoom -t:.1
2482: .Pp
2483: Is equivalent to:
2484: .Pp
2485: .Dl resize-pane -Z -t:.1
2486: .Pp
2487: Note that aliases are expanded when a command is parsed rather than when it is
2488: executed, so binding an alias with
2489: .Ic bind-key
2490: will bind the expanded form.
1.425 nicm 2491: .It Ic default-terminal Ar terminal

1.245 nicm 3552: and separating two alternatives with a comma;
3553: if the specified variable exists and is not zero, the first alternative
1.246 jmc 3554: is chosen, otherwise the second is used.
3555: For example
1.245 nicm 3556: .Ql #{?session_attached,attached,not attached}
3557: will include the string
3558: .Ql attached
3559: if the session is attached and the string
3560: .Ql not attached
1.409 nicm 3561: if it is unattached, or

3613: .Ql #{=-5:pane_title}
3614: the last 5 characters.
1.453 nicm 3615: Prefixing a time variable with
3616: .Ql t:
3617: will convert it to a string, so if

3632: of the variable respectively.
1.461 nicm 3633: A prefix of the form
3634: .Ql s/foo/bar/:
3635: will substitute
3636: .Ql foo
3637: with
3638: .Ql bar
3639: throughout.
1.431 nicm 3640: .Pp
3641: In addition, the first line of a shell command's output may be inserted using
3642: .Ql #() .
3643: For example,
3644: .Ql #(uptime)
3645: will insert the system's uptime.
3646: When constructing formats,
3647: .Nm
3648: does not wait for
3649: .Ql #()
3650: commands to finish; instead, the previous result from running the same command is used,
3651: or a placeholder if the command has not been run before.
1.543 nicm 3652: If the command hasn't exited, the most recent line of output will be used, but the status
3653: line will not be updated more than once a second.
1.431 nicm 3654: Commands are executed with the
