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.

1747: The search commands come in several varieties:
1748: .Ql search-forward
1749: and
1750: .Ql search-backward
1751: search for a regular expression;
1752: the
1753: .Ql -text
1754: variants search for a plain text string rather than a regular expression;
1755: .Ql -incremental
1756: perform an incremental search and expect to be used with the
1757: .Fl i
1758: flag to the
1759: .Ic command-prompt
1760: command.
1761: .Ql search-again
1762: repeats the last search and
1763: .Ql search-reverse
1764: does the same but reverses the direction (forward becomes backward and backward
1765: becomes forward).
1.589 nicm 1766: .Pp
1.633 nicm 1767: Copy commands may take an optional buffer prefix argument which is used
1768: to generate the buffer name (the default is
1769: .Ql buffer
1770: so buffers are named
1771: .Ql buffer0 ,
1772: .Ql buffer1
1773: and so on).
1774: Pipe commands take a command argument which is the command to which the
1.820 nicm 1775: selected text is piped.
1776: .Ql copy-pipe
1777: variants also copy the selection.
1.589 nicm 1778: The
1779: .Ql -and-cancel
1780: variants of some commands exit copy mode after they have completed (for copy
1781: commands) or when the cursor reaches the bottom (for scrolling commands).
1.638 nicm 1782: .Ql -no-clear
1783: variants do not clear the selection.
1.146 nicm 1784: .Pp
1785: The next and previous word keys use space and the
1786: .Ql - ,
1.154 nicm 1787: .Ql _
1.146 nicm 1788: and
1789: .Ql @
1.154 nicm 1790: characters as word delimiters by default, but this can be adjusted by
1791: setting the
1792: .Em word-separators
1.255 nicm 1793: session option.
1.146 nicm 1794: Next word moves to the start of the next word, next word end to the end of the
1795: next word and previous word to the start of the previous word.
1796: The three next and previous space keys work similarly but use a space alone as
1797: the word separator.
1.157 nicm 1798: .Pp
1799: The jump commands enable quick movement within a line.
1800: For instance, typing
1801: .Ql f
1802: followed by
1803: .Ql /
1804: will move the cursor to the next
1805: .Ql /
1806: character on the current line.
1807: A
1808: .Ql \&;
1809: will then jump to the next occurrence.
1.1 nicm 1810: .Pp
1.155 nicm 1811: Commands in copy mode may be prefaced by an optional repeat count.
1812: With vi key bindings, a prefix is entered using the number keys; with
1813: emacs, the Alt (meta) key and a number begins prefix entry.
1814: .Pp
1.164 nicm 1815: The synopsis for the

1.450 nicm 1841: .Fl e
1842: specifies that scrolling to the bottom of the history (to the visible screen)
1843: should exit copy mode.
1844: While in copy mode, pressing a key other than those used for scrolling will
1845: disable this behaviour.
1846: This is intended to allow fast scrolling through a pane's history, for
1847: example with:
1848: .Bd -literal -offset indent

1.679 nicm 1853: A number of preset arrangements of panes are available, these are called layouts.
1.38 nicm 1854: These may be selected with the
1855: .Ic select-layout
1856: command or cycled with
1857: .Ic next-layout

1867: .It Ic even-vertical
1868: Panes are spread evenly from top to bottom.
1.2 nicm 1869: .It Ic main-horizontal
1.131 nicm 1870: A large (main) pane is shown at the top of the window and the remaining panes
1871: are spread from left to right in the leftover space at the bottom.
1.2 nicm 1872: Use the
1873: .Em main-pane-height
1874: window option to specify the height of the top pane.
1.1 nicm 1875: .It Ic main-vertical
1.2 nicm 1876: Similar to
1877: .Ic main-horizontal
1878: but the large pane is placed on the left and the others spread from top to
1879: bottom along the right.
1880: See the
1881: .Em main-pane-width
1882: window option.
1.165 nicm 1883: .It Ic tiled
1884: Panes are spread out as evenly as possible over the window in both rows and

1.8 nicm 1887: .Pp
1.181 nicm 1888: In addition,
1889: .Ic select-layout
1890: may be used to apply a previously used layout - the
1891: .Ic list-windows
1892: command displays the layout of each window in a form suitable for use with
1893: .Ic select-layout .
1894: For example:
1895: .Bd -literal -offset indent
1896: $ tmux list-windows
1897: 0: ksh [159x48]
1898: layout: bb62,159x48,0,0{79x48,0,0,79x48,80,0}

1900: .Ed
1.196 nicm 1901: .Pp
1.181 nicm 1902: .Nm

1.57 jmc 3159: .El
3160: .Sh OPTIONS
3161: The appearance and behaviour of
3162: .Nm
3163: may be modified by changing the value of various options.
1.668 nicm 3164: There are four types of option:
1.133 nicm 3165: .Em server options ,
1.831 nicm 3166: .Em session options ,
3167: .Em window options ,
1.57 jmc 3168: and
1.668 nicm 3169: .Em pane options .
1.57 jmc 3170: .Pp
1.133 nicm 3171: The
3172: .Nm
1.686 nicm 3173: server has a set of global server options which do not apply to any particular
1.668 nicm 3174: window or session or pane.
1.133 nicm 3175: These are altered with the
3176: .Ic set-option
3177: .Fl s
3178: command, or displayed with the
3179: .Ic show-options
3180: .Fl s
3181: command.
3182: .Pp
3183: In addition, each individual session may have a set of session options, and
3184: there is a separate set of global session options.
1.57 jmc 3185: Sessions which do not have a particular option configured inherit the value
3186: from the global session options.
3187: Session options are set or unset with the
3188: .Ic set-option
3189: command and may be listed with the
3190: .Ic show-options
3191: command.
1.133 nicm 3192: The available server and session options are listed under the
1.57 jmc 3193: .Ic set-option
3194: command.
3195: .Pp
1.668 nicm 3196: Similarly, a set of window options is attached to each window and a set of pane
3197: options to each pane.
3198: Pane options inherit from window options.
3199: This means any pane option may be set as a window option to apply the option to
3200: all panes in the window without the option set, for example these commands will
3201: set the background colour to red for all panes except pane 0:
3202: .Bd -literal -offset indent
3203: set -w window-style bg=red
3204: set -pt:.0 window-style bg=blue
3205: .Ed
3206: .Pp
3207: There is also a set of global window options from which any unset window or
3208: pane options are inherited.
3209: Window and pane options are altered with
3210: .Ic set-option
3211: .Fl w
3212: and
3213: .Fl p
3214: commands and displayed with
3215: .Ic show-option
3216: .Fl w
3217: and
3218: .Fl p .
1.318 nicm 3219: .Pp
3220: .Nm
3221: also supports user options which are prefixed with a

1.321 jmc 3223: User options may have any name, so long as they are prefixed with
3224: .Ql \&@ ,
1.318 nicm 3225: and be set to any string.
1.418 nicm 3226: For example:
1.318 nicm 3227: .Bd -literal -offset indent
1.774 nicm 3228: $ tmux set -wq @foo "abc123"
3229: $ tmux show -wv @foo
1.318 nicm 3230: abc123

1.133 nicm 3245: a server option with
3246: .Fl s ,
3247: otherwise a session option.
1.637 nicm 3248: If the option is not a user option,
3249: .Fl w
1.668 nicm 3250: or
1.637 nicm 3251: .Fl s
1.668 nicm 3252: may be unnecessary -
1.637 nicm 3253: .Nm
1.668 nicm 3254: will infer the type from the option name, assuming
3255: .Fl w
3256: for pane options.
1.133 nicm 3257: If
3258: .Fl g
1.433 nicm 3259: is given, the global session or window option is set.
1.637 nicm 3260: .Pp
1.550 nicm 3261: .Fl F
3262: expands formats in the option value.
1.1 nicm 3263: The
3264: .Fl u
3265: flag unsets an option, so a session inherits the option from the global
1.433 nicm 3266: options (or with
3267: .Fl g ,
3268: restores a global option to the default).
1.808 nicm 3269: .Fl U
3270: unsets an option (like
3271: .Fl u )
3272: but if the option is a pane option also unsets the option on any panes in the
3273: window.
1.796 nicm 3274: .Ar value
3275: depends on the option and may be a number, a string, or a flag (on, off, or
3276: omitted to toggle).
1.336 nicm 3277: .Pp
3278: The
3279: .Fl o
1.446 nicm 3280: flag prevents setting an option that is already set and the
1.281 nicm 3281: .Fl q
1.446 nicm 3282: flag suppresses errors about unknown or ambiguous options.
1.281 nicm 3283: .Pp
1.378 nicm 3284: With
3285: .Fl a ,
3286: and if the option expects a string or a style,
3287: .Ar value
3288: is appended to the existing setting.
3289: For example:
3290: .Bd -literal -offset indent
3291: set -g status-left "foo"
3292: set -ag status-left "bar"
3293: .Ed
3294: .Pp
3295: Will result in

3298: .Bd -literal -offset indent
3299: set -g status-style "bg=red"
3300: set -ag status-style "fg=blue"
3301: .Ed
3302: .Pp
3303: Will result in a red background
3304: .Em and
3305: blue foreground.
3306: Without

3319: the window options with
3320: .Fl w ,
3321: the server options with

3324: If the option is not a user option,
3325: .Fl w
3326: or
3327: .Fl s
3328: may be unnecessary -
3329: .Nm
3330: will infer the type from the option name, assuming
3331: .Fl w
3332: for pane options.
3333: Global session or window options are listed if
3334: .Fl g
3335: is used.
3336: .Fl v
3337: shows only the option value, not the name.
3338: If
3339: .Fl q
3340: is set, no error will be returned if
3341: .Ar option
3342: is unset.
3343: .Fl H
3344: includes hooks (omitted by default).

1.133 nicm 3349: .Pp
3350: Available server options are:
3351: .Bl -tag -width Ds
1.695 nicm 3352: .It Ic backspace Ar key
3353: Set the key sent by

3364: If an unknown command matches
3365: .Ar name ,
3366: it is replaced with
3367: .Ar value .
3368: For example, after:
3369: .Pp
1.565 nicm 3370: .Dl set -s command-alias[100] zoom='resize-pane -Z'
1.526 nicm 3371: .Pp
3372: Using:

3375: .Pp
3376: Is equivalent to:
3377: .Pp
3378: .Dl resize-pane -Z -t:.1
3379: .Pp
3380: Note that aliases are expanded when a command is parsed rather than when it is

3382: .Ic bind-key
3383: will bind the expanded form.
1.425 nicm 3384: .It Ic default-terminal Ar terminal

1.724 nicm 4492: .Pp
4493: The

4495: events are fired for the second click of a double click, even if there may be a
4496: third click which will fire
4497: .Ql TripleClick
4498: instead of
4499: .Ql DoubleClick .
1.419 nicm 4500: .Pp
4501: Each should be suffixed with a location, for example
4502: .Ql MouseDown1Status .
4503: .Pp
1.423 nicm 4504: The special token
4505: .Ql {mouse}
4506: or
1.419 nicm 4507: .Ql =
4508: may be used as
4509: .Ar target-window
4510: or
4511: .Ar target-pane
4512: in commands bound to mouse key bindings.
4513: It resolves to the window or pane over which the mouse event took place
4514: (for example, the window in the status line over which button 1 was released for a
4515: .Ql MouseUp1Status
4516: binding, or the pane over which the wheel was scrolled for a
4517: .Ql WheelDownPane
4518: binding).
4519: .Pp
4520: The
4521: .Ic send-keys
4522: .Fl M
4523: flag may be used to forward a mouse event to a pane.
4524: .Pp
4525: The default key bindings allow the mouse to be used to select and resize panes,
4526: to copy text and to change window using the status line.
4527: These take effect if the
4528: .Ic mouse
4529: option is turned on.
1.245 nicm 4530: .Sh FORMATS
1.294 nicm 4531: Certain commands accept the
1.245 nicm 4532: .Fl F
4533: flag with a
4534: .Ar format
4535: argument.
4536: This is a string which controls the output format of the command.
1.678 nicm 4537: Format variables are enclosed in
1.245 nicm 4538: .Ql #{
4539: and
4540: .Ql } ,
4541: for example
1.359 nicm 4542: .Ql #{session_name} .
1.409 nicm 4543: The possible variables are listed in the table below, or the name of a
4544: .Nm
4545: option may be used for an option's value.
4546: Some variables have a shorter alias such as
1.598 nicm 4547: .Ql #S ;
1.376 nicm 4548: .Ql ##
4549: is replaced by a single
1.598 nicm 4550: .Ql # ,
4551: .Ql #,
4552: by a
4553: .Ql \&,
4554: and
4555: .Ql #}
4556: by a
4557: .Ql } .
1.409 nicm 4558: .Pp
4559: Conditionals are available by prefixing with
1.246 jmc 4560: .Ql \&?
1.245 nicm 4561: and separating two alternatives with a comma;
4562: if the specified variable exists and is not zero, the first alternative
1.246 jmc 4563: is chosen, otherwise the second is used.
4564: For example
1.245 nicm 4565: .Ql #{?session_attached,attached,not attached}
4566: will include the string
4567: .Ql attached
4568: if the session is attached and the string
4569: .Ql not attached
1.409 nicm 4570: if it is unattached, or
4571: .Ql #{?automatic-rename,yes,no}
4572: will include

4574: if
4575: .Ic automatic-rename
4576: is enabled, or
4577: .Ql no
4578: if not.
1.599 nicm 4579: Conditionals can be nested arbitrarily.
4580: Inside a conditional,
4581: .Ql \&,
4582: and
4583: .Ql }
4584: must be escaped as
4585: .Ql #,
4586: and
4587: .Ql #} ,
4588: unless they are part of a
4589: .Ql #{...}
1.600 nicm 4590: replacement.
4591: For example:
1.599 nicm 4592: .Bd -literal -offset indent
4593: #{?pane_in_mode,#[fg=white#,bg=red],#[fg=red#,bg=white]}#W .
4594: .Ed
1.520 nicm 4595: .Pp
1.678 nicm 4596: String comparisons may be expressed by prefixing two comma-separated

1.652 nicm 4598: .Ql == ,
4599: .Ql != ,
4600: .Ql < ,
4601: .Ql > ,
4602: .Ql <=
1.520 nicm 4603: or
1.652 nicm 4604: .Ql >=
1.520 nicm 4605: and a colon.
4606: For example
1.544 nicm 4607: .Ql #{==:#{host},myhost}
1.520 nicm 4608: will be replaced by
4609: .Ql 1
4610: if running on
4611: .Ql myhost ,
4612: otherwise by
1.554 nicm 4613: .Ql 0 .
4614: .Ql ||
4615: and
4616: .Ql &&
4617: evaluate to true if either or both of two comma-separated alternatives are
4618: true, for example
1.595 nicm 4619: .Ql #{||:#{pane_in_mode},#{alternate_on}} .
1.664 nicm 4620: .Pp
4621: An
4622: .Ql m
4623: specifies an
4624: .Xr fnmatch 3
4625: or regular expression comparison.
4626: The first argument is the pattern and the second the string to compare.
1.714 nicm 4627: An optional argument specifies flags:
1.664 nicm 4628: .Ql r
4629: means the pattern is a regular expression instead of the default
4630: .Xr fnmatch 3
4631: pattern, and
4632: .Ql i
4633: means to ignore case.
4634: For example:
4635: .Ql #{m:*foo*,#{host}}
4636: or
4637: .Ql #{m/ri:^A,MYVAR} .
1.554 nicm 4638: A
4639: .Ql C
4640: performs a search for an
4641: .Xr fnmatch 3
1.664 nicm 4642: pattern or regular expression in the pane content and evaluates to zero if not
4643: found, or a line number if found.
4644: Like
4645: .Ql m ,
1.665 jmc 4646: an
1.664 nicm 4647: .Ql r
4648: flag means search for a regular expression and
4649: .Ql i
4650: ignores case.
4651: For example:
4652: .Ql #{C/r:^Start}
1.714 nicm 4653: .Pp
4654: Numeric operators may be performed by prefixing two comma-separated alternatives with an
4655: .Ql e
4656: and an operator.
4657: An optional
4658: .Ql f
4659: flag may be given after the operator to use floating point numbers, otherwise integers are used.
4660: This may be followed by a number giving the number of decimal places to use for the result.
4661: The available operators are:
4662: addition
4663: .Ql + ,
4664: subtraction
4665: .Ql - ,
4666: multiplication
4667: .Ql * ,
4668: division
4669: .Ql / ,
1.801 nicm 4670: modulus
1.714 nicm 4671: .Ql m
4672: or
4673: .Ql %
4674: (note that
4675: .Ql %
4676: must be escaped as
4677: .Ql %%
4678: in formats which are also expanded by
1.801 nicm 4679: .Xr strftime 3 )
4680: and numeric comparison operators
4681: .Ql == ,
4682: .Ql != ,
4683: .Ql < ,
4684: .Ql <= ,
4685: .Ql >
4686: and
4687: .Ql >= .
1.714 nicm 4688: For example,
4689: .Ql #{e|*|f|4:5.5,3}
4690: multiplies 5.5 by 3 for a result with four decimal places and
4691: .Ql #{e|%%:7,3}
4692: returns the modulus of 7 and 3.
1.833 nicm 4693: .Ql a
4694: replaces a numeric argument by its ASCII equivalent, so
4695: .Ql #{a:98}
4696: results in
4697: .Ql b .
1.453 nicm 4698: .Pp
1.367 nicm 4699: A limit may be placed on the length of the resultant string by prefixing it
4700: by an
4701: .Ql = ,
1.479 nicm 4702: a number and a colon.
4703: Positive numbers count from the start of the string and negative from the end,
4704: so
4705: .Ql #{=5:pane_title}
1.653 nicm 4706: will include at most the first five characters of the pane title, or
1.479 nicm 4707: .Ql #{=-5:pane_title}
1.653 nicm 4708: the last five characters.
4709: A suffix or prefix may be given as a second argument - if provided then it is
4710: appended or prepended to the string if the length has been trimmed, for example
4711: .Ql #{=/5/...:pane_title}
4712: will append
4713: .Ql ...
4714: if the pane title is more than five characters.
1.698 nicm 4715: Similarly,
4716: .Ql p
4717: pads the string to a given width, for example
4718: .Ql #{p10:pane_title}
4719: will result in a width of at least 10 characters.
4720: A positive width pads on the left, a negative on the right.
1.791 nicm 4721: .Ql n
1.803 nicm 4722: expands to the length of the variable and
4723: .Ql w
4724: to its width when displayed, for example
1.791 nicm 4725: .Ql #{n:window_name} .
1.653 nicm 4726: .Pp
1.453 nicm 4727: Prefixing a time variable with
1.683 nicm 4728: .Ql t:\&
1.453 nicm 4729: will convert it to a string, so if
4730: .Ql #{window_activity}
4731: gives
1.454 jmc 4732: .Ql 1445765102 ,
1.453 nicm 4733: .Ql #{t:window_activity}
4734: gives
4735: .Ql Sun Oct 25 09:25:02 2015 .
1.751 nicm 4736: Adding
4737: .Ql p (
4738: .Ql `t/p` )
4739: will use shorter but less accurate time format for times in the past.
1.765 nicm 4740: A custom format may be given using an
4741: .Ql f
4742: suffix (note that
4743: .Ql %
4744: must be escaped as
4745: .Ql %%
4746: if the format is separately being passed through
4747: .Xr strftime 3 ,
4748: for example in the
4749: .Ic status-left
4750: option):
4751: .Ql #{t/f/%%H#:%%M:window_activity} ,
4752: see
4753: .Xr strftime 3 .
4754: .Pp
1.453 nicm 4755: The
1.683 nicm 4756: .Ql b:\&
1.453 nicm 4757: and
1.683 nicm 4758: .Ql d:\&
1.453 nicm 4759: prefixes are
4760: .Xr basename 3
4761: and
4762: .Xr dirname 3
4763: of the variable respectively.
1.683 nicm 4764: .Ql q:\&
1.610 nicm 4765: will escape
4766: .Xr sh 1
1.812 nicm 4767: special characters or with a
4768: .Ql h
1.806 nicm 4769: suffix, escape hash characters (so
4770: .Ql #
4771: becomes
1.807 nicm 4772: .Ql ## ) .
1.683 nicm 4773: .Ql E:\&
1.617 nicm 4774: will expand the format twice, for example
4775: .Ql #{E:status-left}
4776: is the result of expanding the content of the
4777: .Ic status-left
1.671 nicm 4778: option rather than the option itself.
1.683 nicm 4779: .Ql T:\&
1.620 nicm 4780: is like
1.683 nicm 4781: .Ql E:\&
1.620 nicm 4782: but also expands
4783: .Xr strftime 3
4784: specifiers.
1.683 nicm 4785: .Ql S:\& ,
4786: .Ql W:\&
1.618 nicm 4787: or
1.683 nicm 4788: .Ql P:\&
1.618 nicm 4789: will loop over each session, window or pane and insert the format once
1.619 nicm 4790: for each.
4791: For windows and panes, two comma-separated formats may be given:
4792: the second is used for the current window or active pane.
4793: For example, to get a list of windows formatted like the status line:
1.618 nicm 4794: .Bd -literal -offset indent
4795: #{W:#{E:window-status-format} ,#{E:window-status-current-format} }
4796: .Ed
1.817 nicm 4797: .Pp
4798: .Ql N:\&
4799: checks if a window (without any suffix or with the
4800: .Ql w
4801: suffix) or a session (with the
4802: .Ql s
4803: suffix) name exists, for example
4804: .Ql `N/w:foo`
4805: is replaced with 1 if a window named
4806: .Ql foo
4807: exists.
1.625 nicm 4808: .Pp
1.461 nicm 4809: A prefix of the form
1.683 nicm 4810: .Ql s/foo/bar/:\&
1.461 nicm 4811: will substitute
4812: .Ql foo
4813: with
4814: .Ql bar
4815: throughout.
1.664 nicm 4816: The first argument may be an extended regular expression and a final argument may be
4817: .Ql i
4818: to ignore case, for example
1.683 nicm 4819: .Ql s/a(.)/\e1x/i:\&
1.664 nicm 4820: would change
4821: .Ql abABab
4822: into
4823: .Ql bxBxbx .
1.431 nicm 4824: .Pp
1.671 nicm 4825: In addition, the last line of a shell command's output may be inserted using
1.431 nicm 4826: .Ql #() .
4827: For example,
4828: .Ql #(uptime)
4829: will insert the system's uptime.
4830: When constructing formats,
4831: .Nm
4832: does not wait for
4833: .Ql #()
4834: commands to finish; instead, the previous result from running the same command is used,
4835: or a placeholder if the command has not been run before.
1.543 nicm 4836: If the command hasn't exited, the most recent line of output will be used, but the status
4837: line will not be updated more than once a second.
1.431 nicm 4838: Commands are executed with the
4839: .Nm
4840: global environment set (see the

1.431 nicm 4842: section).
1.671 nicm 4843: .Pp
4844: An

4846: specifies that a string should be interpreted literally and not expanded.
4847: For example

6266: When
6267: .Nm
6268: is started, it inspects the following environment variables:
6269: .Bl -tag -width LC_CTYPE
6270: .It Ev EDITOR
6271: If the command specified in this variable contains the string
6272: .Ql vi
6273: and
6274: .Ev VISUAL
6275: is unset, use vi-style key bindings.
6276: Overridden by the
6277: .Ic mode-keys
6278: and
6279: .Ic status-keys
6280: options.
6281: .It Ev HOME
6282: The user's login directory.
6283: If unset, the
6284: .Xr passwd 5
6285: database is consulted.
6286: .It Ev LC_CTYPE
6287: The character encoding
6288: .Xr locale 1 .
6289: It is used for two separate purposes.
6290: For output to the terminal, UTF-8 is used if the
6291: .Fl u
6292: option is given or if
6293: .Ev LC_CTYPE
6294: contains
6295: .Qq UTF-8
6296: or
6297: .Qq UTF8 .
6298: Otherwise, only ASCII characters are written and non-ASCII characters
6299: are replaced with underscores
6300: .Pq Ql _ .
6301: For input,
6302: .Nm
6303: always runs with a UTF-8 locale.
6304: If en_US.UTF-8 is provided by the operating system it is used and
6305: .Ev LC_CTYPE
6306: is ignored for input.
6307: Otherwise,
6308: .Ev LC_CTYPE
6309: tells
6310: .Nm
6311: what the UTF-8 locale is called on the current system.
6312: If the locale specified by
6313: .Ev LC_CTYPE
6314: is not available or is not a UTF-8 locale,
6315: .Nm
6316: exits with an error message.
6317: .It Ev LC_TIME
6318: The date and time format
6319: .Xr locale 1 .
6320: It is used for locale-dependent
6321: .Xr strftime 3
6322: format specifiers.
6323: .It Ev PWD
6324: The current working directory to be set in the global environment.
6325: This may be useful if it contains symbolic links.
6326: If the value of the variable does not match the current working
6327: directory, the variable is ignored and the result of
6328: .Xr getcwd 3
6329: is used instead.
6330: .It Ev SHELL
6331: The absolute path to the default shell for new windows.
6332: See the
6333: .Ic default-shell
6334: option for details.
6335: .It Ev TMUX_TMPDIR
6336: The parent directory of the directory containing the server sockets.
6337: See the
6338: .Fl L
6339: option for details.
6340: .It Ev VISUAL
6341: If the command specified in this variable contains the string
6342: .Ql vi ,
6343: use vi-style key bindings.
