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

771: .Ql mysess ,
772: not
773: .Ql mysession ) .
1.441 nicm 774: .Pp
1.423 nicm 775: If a single session is found, it is used as the target session; multiple matches
1.57 jmc 776: produce an error.

1601: A window may be split into panes using the
1602: .Ic split-window
1603: command.
1604: Windows may be split horizontally (with the
1605: .Fl h
1606: flag) or vertically.
1607: Panes may be resized with the
1608: .Ic resize-pane
1609: command (bound to
1610: .Ql C-Up ,
1611: .Ql C-Down
1612: .Ql C-Left

1621: commands may be used to swap panes without changing their position.
1622: Panes are numbered beginning from zero in the order they are created.
1623: .Pp
1624: By default, a
1.1 nicm 1625: .Nm
1.679 nicm 1626: pane permits direct access to the terminal contained in the pane.
1627: A pane may also be put into one of several modes:
1628: .Bl -dash -offset indent
1629: .It
1630: Copy mode, which permits a section of a window or its
1.164 nicm 1631: history to be copied to a
1.1 nicm 1632: .Em paste buffer
1633: for later insertion into another window.
1634: This mode is entered with the
1635: .Ic copy-mode
1636: command, bound to
1.113 nicm 1637: .Ql \&[
1.1 nicm 1638: by default.
1.734 nicm 1639: Copied text can be pasted with the
1640: .Ic paste-buffer
1641: command, bound to

1.679 nicm 1643: .It
1644: View mode, which is like copy mode but is entered when a command that produces
1645: output, such as
1.164 nicm 1646: .Ic list-keys ,
1647: is executed from a key binding.
1.679 nicm 1648: .It
1649: Choose mode, which allows an item to be chosen from a list.
1650: This may be a client, a session or window or pane, or a buffer.

1.1 nicm 1658: .Pp
1.678 nicm 1659: In copy mode an indicator is displayed in the top-right corner of the pane with
1660: the current position and the number of lines in the history.
1661: .Pp
1.497 nicm 1662: Commands are sent to copy mode using the
1663: .Fl X
1664: flag to the
1665: .Ic send-keys

1.1 nicm 1761: .El
1.726 nicm 1762: .Pp
1763: The search commands come in several varieties:
1764: .Ql search-forward
1765: and
1766: .Ql search-backward
1767: search for a regular expression;
1768: the
1769: .Ql -text
1770: variants search for a plain text string rather than a regular expression;
1771: .Ql -incremental
1772: perform an incremental search and expect to be used with the
1773: .Fl i
1774: flag to the
1775: .Ic command-prompt
1776: command.
1777: .Ql search-again
1778: repeats the last search and
1779: .Ql search-reverse
1780: does the same but reverses the direction (forward becomes backward and backward
1781: becomes forward).
1.589 nicm 1782: .Pp
1.633 nicm 1783: Copy commands may take an optional buffer prefix argument which is used
1784: to generate the buffer name (the default is
1785: .Ql buffer
1786: so buffers are named
1787: .Ql buffer0 ,
1788: .Ql buffer1
1789: and so on).
1790: Pipe commands take a command argument which is the command to which the
1.820 nicm 1791: selected text is piped.
1792: .Ql copy-pipe
1793: variants also copy the selection.
1.589 nicm 1794: The
1795: .Ql -and-cancel
1796: variants of some commands exit copy mode after they have completed (for copy
1797: commands) or when the cursor reaches the bottom (for scrolling commands).
1.638 nicm 1798: .Ql -no-clear
1799: variants do not clear the selection.
1.146 nicm 1800: .Pp
1.841 nicm 1801: The next and previous word keys skip over whitespace and treat consecutive
1802: runs of either word separators or other letters as words.
1803: Word separators can be customized with the
1.154 nicm 1804: .Em word-separators
1.255 nicm 1805: session option.
1.146 nicm 1806: Next word moves to the start of the next word, next word end to the end of the
1807: next word and previous word to the start of the previous word.
1808: The three next and previous space keys work similarly but use a space alone as
1809: the word separator.
1.841 nicm 1810: Setting
1811: .Em word-separators
1812: to the empty string makes next/previous word equivalent to next/previous space.
1.157 nicm 1813: .Pp
1814: The jump commands enable quick movement within a line.
1815: For instance, typing
1816: .Ql f
1817: followed by
1818: .Ql /
1819: will move the cursor to the next
1820: .Ql /
1821: character on the current line.
1822: A
1823: .Ql \&;
1824: will then jump to the next occurrence.
1.1 nicm 1825: .Pp
1.155 nicm 1826: Commands in copy mode may be prefaced by an optional repeat count.
1827: With vi key bindings, a prefix is entered using the number keys; with
1828: emacs, the Alt (meta) key and a number begins prefix entry.
1829: .Pp
1.164 nicm 1830: The synopsis for the

1840: The
1841: .Fl u
1842: option scrolls one page up.
1.419 nicm 1843: .Fl M
1844: begins a mouse drag (only valid if bound to a mouse key binding, see
1.420 jmc 1845: .Sx MOUSE SUPPORT ) .
1.716 nicm 1846: .Fl H
1847: hides the position indicator in the top right.
1.720 nicm 1848: .Fl q
1849: cancels copy mode and any other modes.
1.735 nicm 1850: .Fl s
1851: copies from

1.716 nicm 1855: .Pp
1.450 nicm 1856: .Fl e
1857: specifies that scrolling to the bottom of the history (to the visible screen)
1858: should exit copy mode.
1859: While in copy mode, pressing a key other than those used for scrolling will
1860: disable this behaviour.
1861: This is intended to allow fast scrolling through a pane's history, for
1862: example with:

1.57 jmc 1866: .El
1.18 nicm 1867: .Pp
1.679 nicm 1868: A number of preset arrangements of panes are available, these are called layouts.
1.38 nicm 1869: These may be selected with the
1870: .Ic select-layout
1871: command or cycled with
1872: .Ic next-layout
1873: (bound to
1.149 nicm 1874: .Ql Space
1.131 nicm 1875: by default); once a layout is chosen, panes within it may be moved and resized
1876: as normal.

1878: The following layouts are supported:
1879: .Bl -tag -width Ds
1880: .It Ic even-horizontal
1881: Panes are spread out evenly from left to right across the window.
1882: .It Ic even-vertical
1883: Panes are spread evenly from top to bottom.
1.2 nicm 1884: .It Ic main-horizontal
1.131 nicm 1885: A large (main) pane is shown at the top of the window and the remaining panes
1886: are spread from left to right in the leftover space at the bottom.
1.2 nicm 1887: Use the
1888: .Em main-pane-height
1889: window option to specify the height of the top pane.
1.1 nicm 1890: .It Ic main-vertical
1.2 nicm 1891: Similar to
1892: .Ic main-horizontal
1893: but the large pane is placed on the left and the others spread from top to
1894: bottom along the right.
1895: See the
1896: .Em main-pane-width
1897: window option.
1.165 nicm 1898: .It Ic tiled
1899: Panes are spread out as evenly as possible over the window in both rows and
1900: columns.
1.1 nicm 1901: .El
1.8 nicm 1902: .Pp
1.181 nicm 1903: In addition,
1904: .Ic select-layout
1905: may be used to apply a previously used layout - the
1906: .Ic list-windows
1907: command displays the layout of each window in a form suitable for use with
1908: .Ic select-layout .
1909: For example:
1910: .Bd -literal -offset indent
1911: $ tmux list-windows
1912: 0: ksh [159x48]
1913: layout: bb62,159x48,0,0{79x48,0,0,79x48,80,0}
1914: $ tmux select-layout bb62,159x48,0,0{79x48,0,0,79x48,80,0}
1915: .Ed
1.196 nicm 1916: .Pp
1.181 nicm 1917: .Nm
1918: automatically adjusts the size of the layout for the current window size.

1.421 nicm 3027: Keys are bound in a key table.
3028: By default (without -T), the key is bound in
3029: the
3030: .Em prefix
3031: key table.
3032: This table is used for keys pressed after the prefix key (for example,
3033: by default

3045: .Ql c
3046: to
3047: .Ic new-window
3048: in the
3049: .Em root

1.57 jmc 3178: .El
3179: .Sh OPTIONS
3180: The appearance and behaviour of
3181: .Nm
3182: may be modified by changing the value of various options.
1.668 nicm 3183: There are four types of option:
1.133 nicm 3184: .Em server options ,
1.831 nicm 3185: .Em session options ,
3186: .Em window options ,
1.57 jmc 3187: and
1.668 nicm 3188: .Em pane options .
1.57 jmc 3189: .Pp
1.133 nicm 3190: The
3191: .Nm
1.686 nicm 3192: server has a set of global server options which do not apply to any particular
1.668 nicm 3193: window or session or pane.
1.133 nicm 3194: These are altered with the
3195: .Ic set-option
3196: .Fl s
3197: command, or displayed with the
3198: .Ic show-options
3199: .Fl s
3200: command.
3201: .Pp
3202: In addition, each individual session may have a set of session options, and
3203: there is a separate set of global session options.
1.57 jmc 3204: Sessions which do not have a particular option configured inherit the value
3205: from the global session options.
3206: Session options are set or unset with the
3207: .Ic set-option
3208: command and may be listed with the
3209: .Ic show-options
3210: command.
1.133 nicm 3211: The available server and session options are listed under the
1.57 jmc 3212: .Ic set-option
3213: command.
3214: .Pp
1.668 nicm 3215: Similarly, a set of window options is attached to each window and a set of pane
3216: options to each pane.
3217: Pane options inherit from window options.
3218: This means any pane option may be set as a window option to apply the option to
3219: all panes in the window without the option set, for example these commands will
3220: set the background colour to red for all panes except pane 0:
3221: .Bd -literal -offset indent
3222: set -w window-style bg=red
3223: set -pt:.0 window-style bg=blue
3224: .Ed
3225: .Pp
3226: There is also a set of global window options from which any unset window or
3227: pane options are inherited.
3228: Window and pane options are altered with
3229: .Ic set-option
3230: .Fl w
3231: and
3232: .Fl p
3233: commands and displayed with
3234: .Ic show-option
3235: .Fl w
3236: and
3237: .Fl p .
1.318 nicm 3238: .Pp
3239: .Nm
3240: also supports user options which are prefixed with a

1.321 jmc 3242: User options may have any name, so long as they are prefixed with
3243: .Ql \&@ ,
1.318 nicm 3244: and be set to any string.
1.418 nicm 3245: For example:
1.318 nicm 3246: .Bd -literal -offset indent
1.774 nicm 3247: $ tmux set -wq @foo "abc123"
3248: $ tmux show -wv @foo
1.318 nicm 3249: abc123

1.1 nicm 3257: .Ar option Ar value
3258: .Xc

3262: a window option with
3263: .Fl w ,
1.133 nicm 3264: a server option with
3265: .Fl s ,
3266: otherwise a session option.
1.637 nicm 3267: If the option is not a user option,
3268: .Fl w
1.668 nicm 3269: or
1.637 nicm 3270: .Fl s
1.668 nicm 3271: may be unnecessary -
1.637 nicm 3272: .Nm
1.668 nicm 3273: will infer the type from the option name, assuming
3274: .Fl w
3275: for pane options.
1.133 nicm 3276: If
3277: .Fl g
1.433 nicm 3278: is given, the global session or window option is set.
1.637 nicm 3279: .Pp
1.550 nicm 3280: .Fl F
3281: expands formats in the option value.
1.1 nicm 3282: The
3283: .Fl u
3284: flag unsets an option, so a session inherits the option from the global
1.433 nicm 3285: options (or with
3286: .Fl g ,
3287: restores a global option to the default).
1.808 nicm 3288: .Fl U
3289: unsets an option (like
3290: .Fl u )
3291: but if the option is a pane option also unsets the option on any panes in the
3292: window.
1.796 nicm 3293: .Ar value
3294: depends on the option and may be a number, a string, or a flag (on, off, or
3295: omitted to toggle).
1.336 nicm 3296: .Pp
3297: The
3298: .Fl o
1.446 nicm 3299: flag prevents setting an option that is already set and the
1.281 nicm 3300: .Fl q
1.446 nicm 3301: flag suppresses errors about unknown or ambiguous options.
1.281 nicm 3302: .Pp
1.378 nicm 3303: With
3304: .Fl a ,
3305: and if the option expects a string or a style,
3306: .Ar value
3307: is appended to the existing setting.
3308: For example:
3309: .Bd -literal -offset indent
3310: set -g status-left "foo"
3311: set -ag status-left "bar"
3312: .Ed
3313: .Pp
3314: Will result in

3317: .Bd -literal -offset indent
3318: set -g status-style "bg=red"
3319: set -ag status-style "fg=blue"
3320: .Ed
3321: .Pp
3322: Will result in a red background
3323: .Em and
3324: blue foreground.
3325: Without
3326: .Fl a ,
3327: the result would be the default background and a blue foreground.

3338: the window options with
3339: .Fl w ,
3340: the server options with

3343: If the option is not a user option,
3344: .Fl w
3345: or
3346: .Fl s
3347: may be unnecessary -
3348: .Nm
3349: will infer the type from the option name, assuming
3350: .Fl w
3351: for pane options.
3352: Global session or window options are listed if
3353: .Fl g
3354: is used.
3355: .Fl v
3356: shows only the option value, not the name.
3357: If
3358: .Fl q
3359: is set, no error will be returned if
3360: .Ar option

3362: .Fl H

1.133 nicm 3368: .Pp
3369: Available server options are:
3370: .Bl -tag -width Ds
1.695 nicm 3371: .It Ic backspace Ar key
3372: Set the key sent by

3383: If an unknown command matches
3384: .Ar name ,
3385: it is replaced with
3386: .Ar value .
3387: For example, after:
3388: .Pp
1.565 nicm 3389: .Dl set -s command-alias[100] zoom='resize-pane -Z'
1.526 nicm 3390: .Pp
3391: Using:

3394: .Pp
3395: Is equivalent to:
3396: .Pp
3397: .Dl resize-pane -Z -t:.1
3398: .Pp
3399: Note that aliases are expanded when a command is parsed rather than when it is
3400: executed, so binding an alias with
3401: .Ic bind-key
3402: will bind the expanded form.
1.425 nicm 3403: .It Ic default-terminal Ar terminal

4597: if the specified variable exists and is not zero, the first alternative
1.246 jmc 4598: is chosen, otherwise the second is used.
4599: For example
1.245 nicm 4600: .Ql #{?session_attached,attached,not attached}
4601: will include the string

1.520 nicm 4638: or
1.652 nicm 4639: .Ql >=

4641: For example
1.544 nicm 4642: .Ql #{==:#{host},myhost}
1.520 nicm 4643: will be replaced by

1.664 nicm 4655: .Pp
4656: An
4657: .Ql m
4658: specifies an
4659: .Xr fnmatch 3
4660: or regular expression comparison.
4661: The first argument is the pattern and the second the string to compare.
1.714 nicm 4662: An optional argument specifies flags:
1.664 nicm 4663: .Ql r
4664: means the pattern is a regular expression instead of the default
4665: .Xr fnmatch 3
4666: pattern, and
4667: .Ql i
4668: means to ignore case.
4669: For example:
4670: .Ql #{m:*foo*,#{host}}
4671: or
4672: .Ql #{m/ri:^A,MYVAR} .
1.554 nicm 4673: A
4674: .Ql C
4675: performs a search for an
4676: .Xr fnmatch 3
1.664 nicm 4677: pattern or regular expression in the pane content and evaluates to zero if not
4678: found, or a line number if found.
4679: Like
4680: .Ql m ,
1.665 jmc 4681: an
1.664 nicm 4682: .Ql r
4683: flag means search for a regular expression and
4684: .Ql i
4685: ignores case.
4686: For example:
4687: .Ql #{C/r:^Start}
1.714 nicm 4688: .Pp
4689: Numeric operators may be performed by prefixing two comma-separated alternatives with an
4690: .Ql e
4691: and an operator.
4692: An optional
4693: .Ql f
4694: flag may be given after the operator to use floating point numbers, otherwise integers are used.
4695: This may be followed by a number giving the number of decimal places to use for the result.
4696: The available operators are:
4697: addition
4698: .Ql + ,
4699: subtraction
4700: .Ql - ,
4701: multiplication
4702: .Ql * ,

1.801 nicm 4705: modulus
1.714 nicm 4706: .Ql m

4708: .Ql %
4709: (note that
4710: .Ql %
4711: must be escaped as
4712: .Ql %%
4713: in formats which are also expanded by
1.801 nicm 4714: .Xr strftime 3 )
4715: and numeric comparison operators
4716: .Ql == ,
4717: .Ql != ,
4718: .Ql < ,
4719: .Ql <= ,
4720: .Ql >
4721: and
4722: .Ql >= .
1.714 nicm 4723: For example,
4724: .Ql #{e|*|f|4:5.5,3}
4725: multiplies 5.5 by 3 for a result with four decimal places and
4726: .Ql #{e|%%:7,3}
4727: returns the modulus of 7 and 3.
1.833 nicm 4728: .Ql a
4729: replaces a numeric argument by its ASCII equivalent, so
4730: .Ql #{a:98}
4731: results in
4732: .Ql b .
1.453 nicm 4733: .Pp
1.367 nicm 4734: A limit may be placed on the length of the resultant string by prefixing it
4735: by an
4736: .Ql = ,
1.479 nicm 4737: a number and a colon.
4738: Positive numbers count from the start of the string and negative from the end,
4739: so
4740: .Ql #{=5:pane_title}
1.653 nicm 4741: will include at most the first five characters of the pane title, or
1.479 nicm 4742: .Ql #{=-5:pane_title}
1.653 nicm 4743: the last five characters.
4744: A suffix or prefix may be given as a second argument - if provided then it is
4745: appended or prepended to the string if the length has been trimmed, for example
4746: .Ql #{=/5/...:pane_title}
4747: will append
4748: .Ql ...
4749: if the pane title is more than five characters.
1.698 nicm 4750: Similarly,
4751: .Ql p
4752: pads the string to a given width, for example
4753: .Ql #{p10:pane_title}
4754: will result in a width of at least 10 characters.
4755: A positive width pads on the left, a negative on the right.
1.791 nicm 4756: .Ql n
1.803 nicm 4757: expands to the length of the variable and
4758: .Ql w
4759: to its width when displayed, for example
1.791 nicm 4760: .Ql #{n:window_name} .
1.653 nicm 4761: .Pp
1.453 nicm 4762: Prefixing a time variable with
1.683 nicm 4763: .Ql t:\&
1.453 nicm 4764: will convert it to a string, so if
4765: .Ql #{window_activity}
4766: gives
1.454 jmc 4767: .Ql 1445765102 ,
1.453 nicm 4768: .Ql #{t:window_activity}
4769: gives
4770: .Ql Sun Oct 25 09:25:02 2015 .
1.751 nicm 4771: Adding
4772: .Ql p (
4773: .Ql `t/p` )
4774: will use shorter but less accurate time format for times in the past.
1.765 nicm 4775: A custom format may be given using an
4776: .Ql f
4777: suffix (note that
4778: .Ql %
4779: must be escaped as
4780: .Ql %%
4781: if the format is separately being passed through
4782: .Xr strftime 3 ,
4783: for example in the

4788: .Xr strftime 3 .
4789: .Pp
1.453 nicm 4790: The

1.453 nicm 4792: and
1.683 nicm 4793: .Ql d:\&
1.453 nicm 4794: prefixes are
4795: .Xr basename 3
4796: and
4797: .Xr dirname 3
4798: of the variable respectively.
1.683 nicm 4799: .Ql q:\&
1.610 nicm 4800: will escape
4801: .Xr sh 1
1.812 nicm 4802: special characters or with a
4803: .Ql h
1.806 nicm 4804: suffix, escape hash characters (so
4805: .Ql #
4806: becomes
1.807 nicm 4807: .Ql ## ) .
1.683 nicm 4808: .Ql E:\&
1.617 nicm 4809: will expand the format twice, for example
4810: .Ql #{E:status-left}
4811: is the result of expanding the content of the
4812: .Ic status-left
1.671 nicm 4813: option rather than the option itself.
1.683 nicm 4814: .Ql T:\&
1.620 nicm 4815: is like
1.683 nicm 4816: .Ql E:\&
1.620 nicm 4817: but also expands

4819: specifiers.
1.683 nicm 4820: .Ql S:\& ,
4821: .Ql W:\&
1.618 nicm 4822: or

1.618 nicm 4824: will loop over each session, window or pane and insert the format once
1.619 nicm 4825: for each.
4826: For windows and panes, two comma-separated formats may be given:
4827: the second is used for the current window or active pane.
4828: For example, to get a list of windows formatted like the status line:
1.618 nicm 4829: .Bd -literal -offset indent
4830: #{W:#{E:window-status-format} ,#{E:window-status-current-format} }
4831: .Ed
1.817 nicm 4832: .Pp
4833: .Ql N:\&
4834: checks if a window (without any suffix or with the
4835: .Ql w
4836: suffix) or a session (with the
4837: .Ql s
4838: suffix) name exists, for example
4839: .Ql `N/w:foo`
4840: is replaced with 1 if a window named
4841: .Ql foo
4842: exists.
1.625 nicm 4843: .Pp
1.461 nicm 4844: A prefix of the form
1.683 nicm 4845: .Ql s/foo/bar/:\&
1.461 nicm 4846: will substitute
4847: .Ql foo
4848: with
4849: .Ql bar
4850: throughout.
1.664 nicm 4851: The first argument may be an extended regular expression and a final argument may be
4852: .Ql i
4853: to ignore case, for example
1.683 nicm 4854: .Ql s/a(.)/\e1x/i:\&
1.664 nicm 4855: would change
4856: .Ql abABab
4857: into

1.431 nicm 4859: .Pp
1.671 nicm 4860: In addition, the last line of a shell command's output may be inserted using
1.431 nicm 4861: .Ql #() .
4862: For example,
4863: .Ql #(uptime)
4864: will insert the system's uptime.
4865: When constructing formats,
4866: .Nm
4867: does not wait for
4868: .Ql #()
4869: commands to finish; instead, the previous result from running the same command is used,
4870: or a placeholder if the command has not been run before.
1.543 nicm 4871: If the command hasn't exited, the most recent line of output will be used, but the status
4872: line will not be updated more than once a second.
1.431 nicm 4873: Commands are executed with the

6352: .Sh ENVIRONMENT
6353: When
6354: .Nm
6355: is started, it inspects the following environment variables:
6356: .Bl -tag -width LC_CTYPE
6357: .It Ev EDITOR
6358: If the command specified in this variable contains the string
6359: .Ql vi
6360: and
6361: .Ev VISUAL
6362: is unset, use vi-style key bindings.
6363: Overridden by the
6364: .Ic mode-keys
6365: and
6366: .Ic status-keys
6367: options.
6368: .It Ev HOME
6369: The user's login directory.
6370: If unset, the
6371: .Xr passwd 5
6372: database is consulted.
6373: .It Ev LC_CTYPE
6374: The character encoding
6375: .Xr locale 1 .
6376: It is used for two separate purposes.
6377: For output to the terminal, UTF-8 is used if the

6379: option is given or if
6380: .Ev LC_CTYPE
6381: contains
6382: .Qq UTF-8
6383: or
6384: .Qq UTF8 .
6385: Otherwise, only ASCII characters are written and non-ASCII characters
6386: are replaced with underscores
6387: .Pq Ql _ .
6388: For input,
6389: .Nm
6390: always runs with a UTF-8 locale.
6391: If en_US.UTF-8 is provided by the operating system it is used and
6392: .Ev LC_CTYPE
6393: is ignored for input.
6394: Otherwise,
6395: .Ev LC_CTYPE
6396: tells
6397: .Nm
6398: what the UTF-8 locale is called on the current system.
6399: If the locale specified by
6400: .Ev LC_CTYPE
6401: is not available or is not a UTF-8 locale,
6402: .Nm
6403: exits with an error message.
6404: .It Ev LC_TIME
6405: The date and time format
6406: .Xr locale 1 .

6409: format specifiers.
6410: .It Ev PWD
6411: The current working directory to be set in the global environment.
6412: This may be useful if it contains symbolic links.
6413: If the value of the variable does not match the current working
6414: directory, the variable is ignored and the result of
6415: .Xr getcwd 3
6416: is used instead.
6417: .It Ev SHELL
6418: The absolute path to the default shell for new windows.
6419: See the
6420: .Ic default-shell
6421: option for details.
6422: .It Ev TMUX_TMPDIR
6423: The parent directory of the directory containing the server sockets.
6424: See the
6425: .Fl L
6426: option for details.
6427: .It Ev VISUAL
6428: If the command specified in this variable contains the string
6429: .Ql vi ,
6430: use vi-style key bindings.
