34: .Sh DESCRIPTION
35: .Nm
1.59 jmc 36: is a terminal multiplexer:
37: it enables a number of terminals to be created, accessed, and
38: controlled from a single screen.
1.67 jmc 39: .Nm
40: may be detached from a screen
41: and continue running in the background,
42: then later reattached.
1.1 nicm 43: .Pp
1.60 nicm 44: When
45: .Nm
46: is started it creates a new
47: .Em session
48: with a single
49: .Em window
50: and displays it on screen.
51: A status line at the bottom of the screen
52: shows information on the current session
53: and is used to enter interactive commands.
54: .Pp
55: A session is a single collection of
56: .Em pseudo terminals
57: under the management of
58: .Nm .
59: Each session has one or more
60: windows linked to it.
61: A window occupies the entire screen
62: and may be split into rectangular panes,
63: each of which is a separate pseudo terminal
64: (the
65: .Xr pty 4
66: manual page documents the technical details of pseudo terminals).
67: Any number of
68: .Nm
69: instances may connect to the same session,
70: and any number of windows may be present in the same session.
71: Once all sessions are killed,
72: .Nm
73: exits.
74: .Pp
1.64 nicm 75: Each session is persistent and will survive accidental disconnection
1.66 jmc 76: (such as
1.64 nicm 77: .Xr ssh 1
1.67 jmc 78: connection timeout) or intentional detaching (with the
1.64 nicm 79: .Ql C-b d
80: key strokes).
81: .Nm
82: may be reattached using:
83: .Pp
84: .Dl $ tmux attach
1.60 nicm 85: .Pp
1.64 nicm 86: In
87: .Nm ,
88: a session is displayed on screen by a
89: .Em client
90: and all sessions are managed by a single
91: .Em server .
92: The server and each client are separate processes which communicate through a
93: socket in
94: .Pa /tmp .
1.65 nicm 95: .Pp
1.1 nicm 96: The options are as follows:
97: .Bl -tag -width "XXXXXXXXXXXX"
98: .It Fl 2
99: Force
100: .Nm
101: to assume the terminal supports 256 colours.
1.744 nicm 102: This is equivalent to
103: .Fl T Ar 256 .
1.345 nicm 104: .It Fl C
1.369 nicm 105: Start in control mode (see the
106: .Sx CONTROL MODE
107: section).
1.345 nicm 108: Given twice
109: .Xo ( Fl CC ) Xc
110: disables echo.
1.91 nicm 111: .It Fl c Ar shell-command
112: Execute
113: .Ar shell-command
114: using the default shell.
115: If necessary, the
116: .Nm
117: server will be started to retrieve the
118: .Ic default-shell
119: option.
1.153 nicm 120: This option is for compatibility with
121: .Xr sh 1
122: when
123: .Nm
124: is used as a login shell.
1.767 nicm 125: .It Fl D
126: Do not start the
127: .Nm
128: server as a daemon.
129: This also turns the
130: .Ic exit-empty
131: option off.
132: With
133: .Fl D ,
134: .Ar command
135: may not be specified.
1.1 nicm 136: .It Fl f Ar file
137: Specify an alternative configuration file.
138: By default,
139: .Nm
1.26 nicm 140: loads the system configuration file from
141: .Pa /etc/tmux.conf ,
142: if present, then looks for a user configuration file at
1.1 nicm 143: .Pa ~/.tmux.conf .
1.306 nicm 144: .Pp
1.1 nicm 145: The configuration file is a set of
146: .Nm
147: commands which are executed in sequence when the server is first started.
1.306 nicm 148: .Nm
149: loads configuration files once when the server process has started.
150: The
151: .Ic source-file
152: command may be used to load a file later.
1.61 nicm 153: .Pp
154: .Nm
1.306 nicm 155: shows any error messages from commands in configuration files in the first
156: session created, and continues to process the rest of the configuration file.
1.1 nicm 157: .It Fl L Ar socket-name
158: .Nm
159: stores the server socket in a directory under
1.455 nicm 160: .Ev TMUX_TMPDIR
161: or
1.208 nicm 162: .Pa /tmp
1.455 nicm 163: if it is unset.
1.355 nicm 164: The default socket is named
1.1 nicm 165: .Em default .
166: This option allows a different socket name to be specified, allowing several
167: independent
168: .Nm
169: servers to be run.
170: Unlike
171: .Fl S
1.789 nicm 172: a full path is not necessary: the sockets are all created in a directory
173: .Pa tmux-UID
174: under the directory given by
175: .Ev TMUX_TMPDIR
176: or in
177: .Pa /tmp .
178: The
179: .Pa tmux-UID
180: directory is created by
181: .Nm
182: and must not be world readable, writable or executable.
1.2 nicm 183: .Pp
184: If the socket is accidentally removed, the
1.6 jmc 185: .Dv SIGUSR1
1.2 nicm 186: signal may be sent to the
187: .Nm
1.422 nicm 188: server process to recreate it (note that this will fail if any parent
189: directories are missing).
1.166 sobrado 190: .It Fl l
191: Behave as a login shell.
192: This flag currently has no effect and is for compatibility with other shells
193: when using tmux as a login shell.
1.811 nicm 194: .It Fl N
195: Do not start the server even if the command would normally do so (for example
196: .Ic new-session
197: or
198: .Ic start-server ) .
1.1 nicm 199: .It Fl S Ar socket-path
200: Specify a full alternative path to the server socket.
201: If
202: .Fl S
203: is specified, the default socket directory is not used and any
204: .Fl L
205: flag is ignored.
206: .It Fl u
1.644 schwarze 207: Write UTF-8 output to the terminal even if the first environment
208: variable of
1.14 nicm 209: .Ev LC_ALL ,
1.644 schwarze 210: .Ev LC_CTYPE ,
211: or
1.2 nicm 212: .Ev LANG
1.644 schwarze 213: that is set does not contain
214: .Qq UTF-8
215: or
216: .Qq UTF8 .
1.744 nicm 217: This is equivalent to
218: .Fl T Ar UTF-8 .
219: .It Fl T Ar features
220: Set terminal features for the client.
221: This is a comma-separated list of features.
222: See the
223: .Ic terminal-features
224: option.
1.1 nicm 225: .It Fl v
226: Request verbose logging.
227: Log messages will be saved into
228: .Pa tmux-client-PID.log
229: and
230: .Pa tmux-server-PID.log
231: files in the current directory, where
232: .Em PID
1.6 jmc 233: is the PID of the server or client process.
1.558 nicm 234: If
235: .Fl v
236: is specified twice, an additional
237: .Pa tmux-out-PID.log
238: file is generated with a copy of everything
239: .Nm
240: writes to the terminal.
241: .Pp
242: The
243: .Dv SIGUSR2
244: signal may be sent to the
245: .Nm
246: server process to toggle logging between on (as if
247: .Fl v
248: was given) and off.
1.708 nicm 249: .It Fl V
250: Report the
251: .Nm
252: version.
1.1 nicm 253: .It Ar command Op Ar flags
254: This specifies one of a set of commands used to control
255: .Nm ,
1.6 jmc 256: as described in the following sections.
1.59 jmc 257: If no commands are specified, the
1.1 nicm 258: .Ic new-session
259: command is assumed.
1.57 jmc 260: .El
1.627 nicm 261: .Sh DEFAULT KEY BINDINGS
1.64 nicm 262: .Nm

264: prefix key,
265: .Ql C-b
266: (Ctrl-b) by default, followed by a command key.
267: .Pp
1.172 nicm 268: The default command key bindings are:

397: commands.
1.651 nicm 398: .Sh COMMAND PARSING AND EXECUTION
399: .Nm
400: supports a large number of commands which can be used to control its
401: behaviour.
402: Each command is named and can accept zero or more flags and arguments.
403: They may be bound to a key with the
404: .Ic bind-key
405: command or run from the shell prompt, a shell script, a configuration file or
406: the command prompt.
407: For example, the same
408: .Ic set-option
409: command run from the shell prompt, from
410: .Pa ~/.tmux.conf
411: and bound to a key may look like:
412: .Bd -literal -offset indent
413: $ tmux set-option -g status-style bg=cyan
414:
415: set-option -g status-style bg=cyan
416:
417: bind-key C set-option -g status-style bg=cyan
418: .Ed
419: .Pp
420: Here, the command name is
421: .Ql set-option ,
422: .Ql Fl g
423: is a flag and
424: .Ql status-style
425: and
426: .Ql bg=cyan
427: are arguments.
428: .Pp
429: .Nm
430: distinguishes between command parsing and execution.
431: In order to execute a command,
432: .Nm
433: needs it to be split up into its name and arguments.
434: This is command parsing.
435: If a command is run from the shell, the shell parses it; from inside
436: .Nm
437: or from a configuration file,
438: .Nm
439: does.
440: Examples of when
441: .Nm
442: parses commands are:
443: .Bl -dash -offset indent
444: .It
445: in a configuration file;
446: .It
447: typed at the command prompt (see
448: .Ic command-prompt ) ;
449: .It
450: given to
451: .Ic bind-key ;
452: .It
453: passed as arguments to
454: .Ic if-shell
455: or
456: .Ic confirm-before .
457: .El
458: .Pp
459: To execute commands, each client has a
460: .Ql command queue .
461: A global command queue not attached to any client is used on startup
462: for configuration files like
463: .Pa ~/.tmux.conf .
464: Parsed commands added to the queue are executed in order.
465: Some commands, like
466: .Ic if-shell
467: and
468: .Ic confirm-before ,
469: parse their argument to create a new command which is inserted immediately
470: after themselves.
471: This means that arguments can be parsed twice or more - once when the parent command (such as
472: .Ic if-shell )
473: is parsed and again when it parses and executes its command.
474: Commands like
475: .Ic if-shell ,
476: .Ic run-shell
477: and
478: .Ic display-panes
479: stop execution of subsequent commands on the queue until something happens -
480: .Ic if-shell
481: and
482: .Ic run-shell
483: until a shell command finishes and
484: .Ic display-panes
485: until a key is pressed.
486: For example, the following commands:
487: .Bd -literal -offset indent
488: new-session; new-window
489: if-shell "true" "split-window"
490: kill-session
491: .Ed
492: .Pp
493: Will execute
494: .Ic new-session ,
495: .Ic new-window ,
496: .Ic if-shell ,
497: the shell command
498: .Xr true 1 ,
1.671 nicm 499: .Ic split-window
1.651 nicm 500: and
501: .Ic kill-session
502: in that order.
503: .Pp
504: The
505: .Sx COMMANDS
506: section lists the
507: .Nm
508: commands and their arguments.
509: .Sh PARSING SYNTAX
510: This section describes the syntax of commands parsed by
511: .Nm ,
512: for example in a configuration file or at the command prompt.
1.671 nicm 513: Note that when commands are entered into the shell, they are parsed by the shell
1.651 nicm 514: - see for example
515: .Xr ksh 1
516: or
517: .Xr csh 1 .
518: .Pp
519: Each command is terminated by a newline or a semicolon (;).
520: Commands separated by semicolons together form a
521: .Ql command sequence
522: - if a command in the sequence encounters an error, no subsequent commands are
523: executed.
1.825 nicm 524: .Pp
525: It is recommended that a semicolon used as a command separator should be
526: written as an individual token, for example from
527: .Xr sh 1 :
528: .Bd -literal -offset indent
529: $ tmux neww \\; splitw
530: .Ed
531: .Pp
532: Or:
533: .Bd -literal -offset indent
534: $ tmux neww ';' splitw
535: .Ed
536: .Pp
537: Or from the tmux command prompt:
538: .Bd -literal -offset indent
539: neww ; splitw
540: .Ed
541: .Pp
542: However, a trailing semicolon is also interpreted as a command separator,
543: for example in these
544: .Xr sh 1
545: commands:
546: .Bd -literal -offset indent
1.826 jmc 547: $ tmux neww\e\e; splitw
1.825 nicm 548: .Ed
549: .Pp
550: Or:
551: .Bd -literal -offset indent
552: $ tmux 'neww;' splitw
553: .Ed
554: .Pp
555: As in these examples, when running tmux from the shell extra care must be taken
556: to properly quote semicolons:
557: .Bl -enum -offset Ds
558: .It
559: Semicolons that should be interpreted as a command separator
560: should be escaped according to the shell conventions.
561: For
562: .Xr sh 1
563: this typically means quoted (such as
564: .Ql neww ';' splitw )
565: or escaped (such as
1.826 jmc 566: .Ql neww \e\e\e\e; splitw ) .
1.825 nicm 567: .It
568: Individual semicolons or trailing semicolons that should be interpreted as
569: arguments should be escaped twice: once according to the shell conventions and
570: a second time for
571: .Nm ;
572: for example:
573: .Bd -literal -offset indent

586: Comments are marked by the unquoted # character - any remaining text after a
587: comment is ignored until the end of the line.
588: .Pp
589: If the last character of a line is \e, the line is joined with the following
590: line (the \e and the newline are completely removed).
591: This is called line continuation and applies both inside and outside quoted
1.656 nicm 592: strings and in comments, but not inside braces.
1.651 nicm 593: .Pp
1.655 nicm 594: Command arguments may be specified as strings surrounded by single (') quotes,
595: double quotes (") or braces ({}).
1.651 nicm 596: .\" "
597: This is required when the argument contains any special character.
1.655 nicm 598: Single and double quoted strings cannot span multiple lines except with line
599: continuation.
600: Braces can span multiple lines.
1.651 nicm 601: .Pp
602: Outside of quotes and inside double quotes, these replacements are performed:
603: .Bl -dash -offset indent
604: .It
605: Environment variables preceded by $ are replaced with their value from the
606: global environment (see the
607: .Sx GLOBAL AND SESSION ENVIRONMENT
608: section).
609: .It
610: A leading ~ or ~user is expanded to the home directory of the current or
611: specified user.
612: .It
613: \euXXXX or \euXXXXXXXX is replaced by the Unicode codepoint corresponding to
614: the given four or eight digit hexadecimal number.
615: .It
616: When preceded (escaped) by a \e, the following characters are replaced: \ee by
617: the escape character; \er by a carriage return; \en by a newline; and \et by a
618: tab.
1.660 nicm 619: .It
620: \eooo is replaced by a character of the octal value ooo.
621: Three octal digits are required, for example \e001.
622: The largest valid character is \e377.
623: .It
1.651 nicm 624: Any other characters preceded by \e are replaced by themselves (that is, the \e
625: is removed) and are not treated as having any special meaning - so for example
626: \e; will not mark a command sequence and \e$ will not expand an environment
627: variable.
628: .El
629: .Pp
1.776 nicm 630: Braces are parsed as a configuration file (so conditions such as
631: .Ql %if
632: are processed) and then converted into a string.
633: They are designed to avoid the need for additional escaping when passing a
634: group of
1.655 nicm 635: .Nm
1.776 nicm 636: commands as an argument (for example to
637: .Ic if-shell ) .
1.655 nicm 638: These two examples produce an identical command - note that no escaping is

1.651 nicm 657: Environment variables may be set by using the syntax
658: .Ql name=value ,
659: for example
660: .Ql HOME=/home/user .
661: Variables set during parsing are added to the global environment.
1.728 nicm 662: A hidden variable may be set with
663: .Ql %hidden ,
664: for example:
665: .Bd -literal -offset indent
666: %hidden MYVAR=42
667: .Ed
668: .Pp
669: Hidden variables are not passed to the environment of processes created

676: .Ql %if ,
677: .Ql %elif ,
678: .Ql %else
679: and
680: .Ql %endif .
681: The argument to
682: .Ql %if
683: and
684: .Ql %elif
685: is expanded as a format (see
686: .Sx FORMATS )
687: and if it evaluates to false (zero or empty), subsequent text is ignored until
688: the closing
689: .Ql %elif ,
690: .Ql %else

1.423 nicm 727: .Pp
1.57 jmc 728: .Ar target-client
1.540 nicm 729: should be the name of the client,
730: typically the

1.441 nicm 774: .Pp
1.423 nicm 775: If a single session is found, it is used as the target session; multiple matches

1789: search for a regular expression;
1790: the
1791: .Ql -text
1792: variants search for a plain text string rather than a regular expression;
1793: .Ql -incremental
1794: perform an incremental search and expect to be used with the
1795: .Fl i
1796: flag to the
1797: .Ic command-prompt
1798: command.
1799: .Ql search-again
1800: repeats the last search and
1801: .Ql search-reverse
1802: does the same but reverses the direction (forward becomes backward and backward
1803: becomes forward).
1.589 nicm 1804: .Pp
1.633 nicm 1805: Copy commands may take an optional buffer prefix argument which is used
1806: to generate the buffer name (the default is
1807: .Ql buffer
1808: so buffers are named
1809: .Ql buffer0 ,
1810: .Ql buffer1
1811: and so on).
1812: Pipe commands take a command argument which is the command to which the
1.820 nicm 1813: selected text is piped.
1814: .Ql copy-pipe
1815: variants also copy the selection.
1.589 nicm 1816: The
1817: .Ql -and-cancel
1818: variants of some commands exit copy mode after they have completed (for copy
1819: commands) or when the cursor reaches the bottom (for scrolling commands).
1.638 nicm 1820: .Ql -no-clear
1821: variants do not clear the selection.
1.146 nicm 1822: .Pp
1.841 nicm 1823: The next and previous word keys skip over whitespace and treat consecutive
1824: runs of either word separators or other letters as words.
1825: Word separators can be customized with the
1.154 nicm 1826: .Em word-separators
1.255 nicm 1827: session option.
1.146 nicm 1828: Next word moves to the start of the next word, next word end to the end of the
1829: next word and previous word to the start of the previous word.
1830: The three next and previous space keys work similarly but use a space alone as
1831: the word separator.
1.841 nicm 1832: Setting
1833: .Em word-separators
1834: to the empty string makes next/previous word equivalent to next/previous space.
1.157 nicm 1835: .Pp
1836: The jump commands enable quick movement within a line.
1837: For instance, typing
1838: .Ql f
1839: followed by
1840: .Ql /
1841: will move the cursor to the next
1842: .Ql /
1843: character on the current line.
1844: A
1845: .Ql \&;
1846: will then jump to the next occurrence.
1.1 nicm 1847: .Pp
1.155 nicm 1848: Commands in copy mode may be prefaced by an optional repeat count.
1849: With vi key bindings, a prefix is entered using the number keys; with

1.505 nicm 4502: Most
1.483 nicm 4503: .Nm
1.505 nicm 4504: commands have an
1.483 nicm 4505: .Em after
4506: hook and there are a number of hooks not associated with commands.
4507: .Pp
1.640 nicm 4508: Hooks are stored as array options, members of the array are executed in
4509: order when the hook is triggered.
1.740 nicm 4510: Like options different hooks may be global or belong to a session, window or pane.
1.640 nicm 4511: Hooks may be configured with the

4522: set-hook -g pane-mode-changed[42] 'set -g status-left-style bg=red'
4523: set-option -g pane-mode-changed[42] 'set -g status-left-style bg=red'
4524: .Ed
4525: .Pp
4526: Setting a hook without specifying an array index clears the hook and sets the
4527: first member of the array.
4528: .Pp
1.505 nicm 4529: A command's after
4530: hook is run after it completes, except when the command is run as part of a hook
1.483 nicm 4531: itself.
1.505 nicm 4532: They are named with an
1.483 nicm 4533: .Ql after-

1.246 jmc 4742: is chosen, otherwise the second is used.
4743: For example
1.245 nicm 4744: .Ql #{?session_attached,attached,not attached}

1.714 nicm 4806: An optional argument specifies flags:
1.664 nicm 4807: .Ql r
4808: means the pattern is a regular expression instead of the default
4809: .Xr fnmatch 3
4810: pattern, and

4816: .Ql #{m/ri:^A,MYVAR} .
1.554 nicm 4817: A
4818: .Ql C
4819: performs a search for an

1.664 nicm 4821: pattern or regular expression in the pane content and evaluates to zero if not

4824: .Ql m ,
1.665 jmc 4825: an
1.664 nicm 4826: .Ql r
4827: flag means search for a regular expression and

4829: ignores case.
4830: For example:
4831: .Ql #{C/r:^Start}
1.714 nicm 4832: .Pp
4833: Numeric operators may be performed by prefixing two comma-separated alternatives with an

4835: and an operator.
4836: An optional
4837: .Ql f
4838: flag may be given after the operator to use floating point numbers, otherwise integers are used.
4839: This may be followed by a number giving the number of decimal places to use for the result.

4862: .Ql < ,
4863: .Ql <= ,
4864: .Ql >

1.714 nicm 4867: For example,
4868: .Ql #{e|*|f|4:5.5,3}
4869: multiplies 5.5 by 3 for a result with four decimal places and
4870: .Ql #{e|%%:7,3}
4871: returns the modulus of 7 and 3.
1.833 nicm 4872: .Ql a
4873: replaces a numeric argument by its ASCII equivalent, so
4874: .Ql #{a:98}
4875: results in
4876: .Ql b .
1.867 nicm 4877: .Ql c

1.479 nicm 4885: a number and a colon.
4886: Positive numbers count from the start of the string and negative from the end,
4887: so
4888: .Ql #{=5:pane_title}
1.653 nicm 4889: will include at most the first five characters of the pane title, or
1.479 nicm 4890: .Ql #{=-5:pane_title}
1.653 nicm 4891: the last five characters.
4892: A suffix or prefix may be given as a second argument - if provided then it is

1.698 nicm 4898: Similarly,
4899: .Ql p
4900: pads the string to a given width, for example
4901: .Ql #{p10:pane_title}
4902: will result in a width of at least 10 characters.
4903: A positive width pads on the left, a negative on the right.
1.791 nicm 4904: .Ql n
1.803 nicm 4905: expands to the length of the variable and
4906: .Ql w
4907: to its width when displayed, for example
1.791 nicm 4908: .Ql #{n:window_name} .
1.653 nicm 4909: .Pp
1.453 nicm 4910: Prefixing a time variable with
1.683 nicm 4911: .Ql t:\&

1.453 nicm 4916: .Ql #{t:window_activity}

4974: For windows and panes, two comma-separated formats may be given:
4975: the second is used for the current window or active pane.
4976: For example, to get a list of windows formatted like the status line:

1.664 nicm 4999: The first argument may be an extended regular expression and a final argument may be
5000: .Ql i
5001: to ignore case, for example
1.683 nicm 5002: .Ql s/a(.)/\e1x/i:\&

5011: .Ql #(uptime)
5012: will insert the system's uptime.
5013: When constructing formats,
5014: .Nm
5015: does not wait for
5016: .Ql #()
5017: commands to finish; instead, the previous result from running the same command is used,
5018: or a placeholder if the command has not been run before.
1.543 nicm 5019: If the command hasn't exited, the most recent line of output will be used, but the status

5376: Only panes have titles.
1.577 nicm 5377: A pane's title is typically set by the program running inside the pane using
5378: an escape sequence (like it would set the
1.261 nicm 5379: .Xr xterm 1
1.577 nicm 5380: window title in
1.578 nicm 5381: .Xr X 7 ) .
1.268 nicm 5382: Windows themselves do not have titles - a window's title is the title of its

5433: .Em global environment ;
5434: in addition, each session has a
5435: .Em session environment .
1.193 nicm 5436: When a window is created, the session and global environments are merged.
5437: If a variable exists in both, the value from the session environment is used.
5438: The result is the initial environment passed to the new process.
1.63 nicm 5439: .Pp
5440: The
5441: .Ic update-environment
5442: session option may be used to update the session environment from the client
