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.

1.726 nicm 1746: .Pp
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

1825: The
1826: .Fl u
1827: option scrolls one page up.
1.419 nicm 1828: .Fl M
1829: begins a mouse drag (only valid if bound to a mouse key binding, see

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
1849: bind PageUp copy-mode -eu
1850: .Ed
1.57 jmc 1851: .El
1.18 nicm 1852: .Pp
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
1858: (bound to
1.149 nicm 1859: .Ql Space

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

3146: .Sh OPTIONS
3147: The appearance and behaviour of
3148: .Nm
3149: may be modified by changing the value of various options.
1.668 nicm 3150: There are four types of option:
1.133 nicm 3151: .Em server options ,
1.57 jmc 3152: .Em session options
1.668 nicm 3153: .Em window options
1.57 jmc 3154: and
1.668 nicm 3155: .Em pane options .
1.57 jmc 3156: .Pp
1.133 nicm 3157: The
3158: .Nm
1.686 nicm 3159: server has a set of global server options which do not apply to any particular
1.668 nicm 3160: window or session or pane.
1.133 nicm 3161: These are altered with the
3162: .Ic set-option
3163: .Fl s
3164: command, or displayed with the
3165: .Ic show-options
3166: .Fl s
3167: command.
3168: .Pp
3169: In addition, each individual session may have a set of session options, and
3170: there is a separate set of global session options.
1.57 jmc 3171: Sessions which do not have a particular option configured inherit the value
3172: from the global session options.
3173: Session options are set or unset with the
3174: .Ic set-option
3175: command and may be listed with the
3176: .Ic show-options
3177: command.
1.133 nicm 3178: The available server and session options are listed under the
1.57 jmc 3179: .Ic set-option
3180: command.
3181: .Pp
1.668 nicm 3182: Similarly, a set of window options is attached to each window and a set of pane
3183: options to each pane.
3184: Pane options inherit from window options.
3185: This means any pane option may be set as a window option to apply the option to
3186: all panes in the window without the option set, for example these commands will
3187: set the background colour to red for all panes except pane 0:
3188: .Bd -literal -offset indent
3189: set -w window-style bg=red
3190: set -pt:.0 window-style bg=blue
3191: .Ed
3192: .Pp
3193: There is also a set of global window options from which any unset window or
3194: pane options are inherited.
3195: Window and pane options are altered with
3196: .Ic set-option
3197: .Fl w
3198: and
3199: .Fl p
3200: commands and displayed with
3201: .Ic show-option
3202: .Fl w
3203: and
3204: .Fl p .
1.318 nicm 3205: .Pp
3206: .Nm
3207: also supports user options which are prefixed with a

1.321 jmc 3209: User options may have any name, so long as they are prefixed with
3210: .Ql \&@ ,
1.318 nicm 3211: and be set to any string.
1.418 nicm 3212: For example:
1.318 nicm 3213: .Bd -literal -offset indent
1.774 nicm 3214: $ tmux set -wq @foo "abc123"
3215: $ tmux show -wv @foo
1.318 nicm 3216: abc123

1.57 jmc 3218: .Pp
3219: Commands which set options are as follows:

1.1 nicm 3221: .It Xo Ic set-option
1.808 nicm 3222: .Op Fl aFgopqsuUw

1.1 nicm 3224: .Ar option Ar value
3225: .Xc
3226: .D1 (alias: Ic set )
1.668 nicm 3227: Set a pane option with

3230: .Fl w ,
1.133 nicm 3231: a server option with
3232: .Fl s ,
3233: otherwise a session option.
1.637 nicm 3234: If the option is not a user option,
3235: .Fl w
1.668 nicm 3236: or
1.637 nicm 3237: .Fl s
1.668 nicm 3238: may be unnecessary -
1.637 nicm 3239: .Nm
1.668 nicm 3240: will infer the type from the option name, assuming
3241: .Fl w
3242: for pane options.
1.133 nicm 3243: If
3244: .Fl g
1.433 nicm 3245: is given, the global session or window option is set.
1.637 nicm 3246: .Pp
1.550 nicm 3247: .Fl F
3248: expands formats in the option value.
1.1 nicm 3249: The
3250: .Fl u
3251: flag unsets an option, so a session inherits the option from the global
1.433 nicm 3252: options (or with
3253: .Fl g ,
3254: restores a global option to the default).
1.808 nicm 3255: .Fl U
3256: unsets an option (like
3257: .Fl u )
3258: but if the option is a pane option also unsets the option on any panes in the
3259: window.
1.796 nicm 3260: .Ar value
3261: depends on the option and may be a number, a string, or a flag (on, off, or
3262: omitted to toggle).
1.336 nicm 3263: .Pp
3264: The
3265: .Fl o
1.446 nicm 3266: flag prevents setting an option that is already set and the
1.281 nicm 3267: .Fl q
1.446 nicm 3268: flag suppresses errors about unknown or ambiguous options.
1.281 nicm 3269: .Pp
1.378 nicm 3270: With
3271: .Fl a ,
3272: and if the option expects a string or a style,
3273: .Ar value
3274: is appended to the existing setting.
3275: For example:
3276: .Bd -literal -offset indent
3277: set -g status-left "foo"
3278: set -ag status-left "bar"
3279: .Ed
3280: .Pp
3281: Will result in

3283: And:
3284: .Bd -literal -offset indent
3285: set -g status-style "bg=red"
3286: set -ag status-style "fg=blue"
3287: .Ed
3288: .Pp
3289: Will result in a red background
3290: .Em and
3291: blue foreground.
3292: Without
3293: .Fl a ,
3294: the result would be the default background and a blue foreground.

3305: the window options with
3306: .Fl w ,
3307: the server options with
3308: .Fl s ,
3309: otherwise the session options.
3310: If the option is not a user option,
3311: .Fl w
3312: or
3313: .Fl s
3314: may be unnecessary -
3315: .Nm
3316: will infer the type from the option name, assuming
3317: .Fl w
3318: for pane options.
3319: Global session or window options are listed if
3320: .Fl g
3321: is used.
3322: .Fl v
3323: shows only the option value, not the name.
3324: If
3325: .Fl q
3326: is set, no error will be returned if
3327: .Ar option
3328: is unset.
3329: .Fl H
3330: includes hooks (omitted by default).
3331: .Fl A

3333: marked with an asterisk.
3334: .El
1.133 nicm 3335: .Pp
3336: Available server options are:
3337: .Bl -tag -width Ds
1.695 nicm 3338: .It Ic backspace Ar key
3339: Set the key sent by

1.526 nicm 3346: .It Xo Ic command-alias[]
3347: .Ar name=value
3348: .Xc
3349: This is an array of custom aliases for commands.
3350: If an unknown command matches
3351: .Ar name ,
3352: it is replaced with
3353: .Ar value .
3354: For example, after:
3355: .Pp
1.565 nicm 3356: .Dl set -s command-alias[100] zoom='resize-pane -Z'
1.526 nicm 3357: .Pp
3358: Using:
3359: .Pp
3360: .Dl zoom -t:.1
3361: .Pp
3362: Is equivalent to:
3363: .Pp
3364: .Dl resize-pane -Z -t:.1
3365: .Pp
3366: Note that aliases are expanded when a command is parsed rather than when it is
3367: executed, so binding an alias with
3368: .Ic bind-key
3369: will bind the expanded form.
1.425 nicm 3370: .It Ic default-terminal Ar terminal

4501: option is turned on.
1.245 nicm 4502: .Sh FORMATS
1.294 nicm 4503: Certain commands accept the
1.245 nicm 4504: .Fl F
4505: flag with a
4506: .Ar format
4507: argument.
4508: This is a string which controls the output format of the command.
1.678 nicm 4509: Format variables are enclosed in
1.245 nicm 4510: .Ql #{
4511: and
4512: .Ql } ,
4513: for example
1.359 nicm 4514: .Ql #{session_name} .
1.409 nicm 4515: The possible variables are listed in the table below, or the name of a
4516: .Nm
4517: option may be used for an option's value.
4518: Some variables have a shorter alias such as
1.598 nicm 4519: .Ql #S ;
1.376 nicm 4520: .Ql ##
4521: is replaced by a single
1.598 nicm 4522: .Ql # ,
4523: .Ql #,
4524: by a
4525: .Ql \&,
4526: and
4527: .Ql #}
4528: by a
4529: .Ql } .
1.409 nicm 4530: .Pp
4531: Conditionals are available by prefixing with
1.246 jmc 4532: .Ql \&?
1.245 nicm 4533: and separating two alternatives with a comma;
4534: if the specified variable exists and is not zero, the first alternative
1.246 jmc 4535: is chosen, otherwise the second is used.
4536: For example
1.245 nicm 4537: .Ql #{?session_attached,attached,not attached}
4538: will include the string
4539: .Ql attached
4540: if the session is attached and the string
4541: .Ql not attached
1.409 nicm 4542: if it is unattached, or
4543: .Ql #{?automatic-rename,yes,no}

4549: .Ql no
4550: if not.
1.599 nicm 4551: Conditionals can be nested arbitrarily.
4552: Inside a conditional,
4553: .Ql \&,
4554: and
4555: .Ql }

1.520 nicm 4575: or
1.652 nicm 4576: .Ql >=
1.520 nicm 4577: and a colon.
4578: For example
1.544 nicm 4579: .Ql #{==:#{host},myhost}
1.520 nicm 4580: will be replaced by
4581: .Ql 1
4582: if running on

1.595 nicm 4591: .Ql #{||:#{pane_in_mode},#{alternate_on}} .
1.664 nicm 4592: .Pp
4593: An
4594: .Ql m
4595: specifies an
4596: .Xr fnmatch 3
4597: or regular expression comparison.
4598: The first argument is the pattern and the second the string to compare.
1.714 nicm 4599: An optional argument specifies flags:
1.664 nicm 4600: .Ql r
4601: means the pattern is a regular expression instead of the default
4602: .Xr fnmatch 3
4603: pattern, and
4604: .Ql i
4605: means to ignore case.
4606: For example:
4607: .Ql #{m:*foo*,#{host}}
4608: or
4609: .Ql #{m/ri:^A,MYVAR} .
1.554 nicm 4610: A
4611: .Ql C
4612: performs a search for an
4613: .Xr fnmatch 3
1.664 nicm 4614: pattern or regular expression in the pane content and evaluates to zero if not
4615: found, or a line number if found.
4616: Like
4617: .Ql m ,
1.665 jmc 4618: an
1.664 nicm 4619: .Ql r
4620: flag means search for a regular expression and
4621: .Ql i
4622: ignores case.
4623: For example:
4624: .Ql #{C/r:^Start}
1.714 nicm 4625: .Pp
4626: Numeric operators may be performed by prefixing two comma-separated alternatives with an
4627: .Ql e
4628: and an operator.
4629: An optional
4630: .Ql f
4631: flag may be given after the operator to use floating point numbers, otherwise integers are used.
4632: This may be followed by a number giving the number of decimal places to use for the result.
4633: The available operators are:
4634: addition
4635: .Ql + ,
4636: subtraction
4637: .Ql - ,
4638: multiplication
4639: .Ql * ,
4640: division
4641: .Ql / ,
1.801 nicm 4642: modulus
1.714 nicm 4643: .Ql m
4644: or
4645: .Ql %
4646: (note that
4647: .Ql %
4648: must be escaped as
4649: .Ql %%
4650: in formats which are also expanded by
1.801 nicm 4651: .Xr strftime 3 )
4652: and numeric comparison operators
4653: .Ql == ,
4654: .Ql != ,
4655: .Ql < ,
4656: .Ql <= ,
4657: .Ql >
4658: and
4659: .Ql >= .
1.714 nicm 4660: For example,
4661: .Ql #{e|*|f|4:5.5,3}
4662: multiplies 5.5 by 3 for a result with four decimal places and
4663: .Ql #{e|%%:7,3}
4664: returns the modulus of 7 and 3.
1.453 nicm 4665: .Pp
1.367 nicm 4666: A limit may be placed on the length of the resultant string by prefixing it
4667: by an
4668: .Ql = ,
1.479 nicm 4669: a number and a colon.
4670: Positive numbers count from the start of the string and negative from the end,
4671: so
4672: .Ql #{=5:pane_title}
1.653 nicm 4673: will include at most the first five characters of the pane title, or
1.479 nicm 4674: .Ql #{=-5:pane_title}
1.653 nicm 4675: the last five characters.
4676: A suffix or prefix may be given as a second argument - if provided then it is
4677: appended or prepended to the string if the length has been trimmed, for example
4678: .Ql #{=/5/...:pane_title}
4679: will append
4680: .Ql ...
4681: if the pane title is more than five characters.
1.698 nicm 4682: Similarly,
4683: .Ql p
4684: pads the string to a given width, for example
4685: .Ql #{p10:pane_title}
4686: will result in a width of at least 10 characters.
4687: A positive width pads on the left, a negative on the right.
1.791 nicm 4688: .Ql n
1.803 nicm 4689: expands to the length of the variable and
4690: .Ql w
4691: to its width when displayed, for example
1.791 nicm 4692: .Ql #{n:window_name} .
1.653 nicm 4693: .Pp
1.453 nicm 4694: Prefixing a time variable with
1.683 nicm 4695: .Ql t:\&
1.453 nicm 4696: will convert it to a string, so if
4697: .Ql #{window_activity}
4698: gives
1.454 jmc 4699: .Ql 1445765102 ,
1.453 nicm 4700: .Ql #{t:window_activity}
4701: gives
4702: .Ql Sun Oct 25 09:25:02 2015 .
1.751 nicm 4703: Adding
4704: .Ql p (
4705: .Ql `t/p` )
4706: will use shorter but less accurate time format for times in the past.
1.765 nicm 4707: A custom format may be given using an
4708: .Ql f
4709: suffix (note that
4710: .Ql %
4711: must be escaped as
4712: .Ql %%
4713: if the format is separately being passed through
4714: .Xr strftime 3 ,
4715: for example in the
4716: .Ic status-left
4717: option):
4718: .Ql #{t/f/%%H#:%%M:window_activity} ,
4719: see
4720: .Xr strftime 3 .
4721: .Pp
1.453 nicm 4722: The

1.453 nicm 4724: and
1.683 nicm 4725: .Ql d:\&
1.453 nicm 4726: prefixes are
4727: .Xr basename 3
4728: and
4729: .Xr dirname 3
4730: of the variable respectively.
1.683 nicm 4731: .Ql q:\&
1.610 nicm 4732: will escape
4733: .Xr sh 1
1.812 nicm 4734: special characters or with a
4735: .Ql h
1.806 nicm 4736: suffix, escape hash characters (so
4737: .Ql #
4738: becomes
1.807 nicm 4739: .Ql ## ) .
1.683 nicm 4740: .Ql E:\&
1.617 nicm 4741: will expand the format twice, for example
4742: .Ql #{E:status-left}
4743: is the result of expanding the content of the
4744: .Ic status-left
1.671 nicm 4745: option rather than the option itself.
1.683 nicm 4746: .Ql T:\&
1.620 nicm 4747: is like
1.683 nicm 4748: .Ql E:\&
1.620 nicm 4749: but also expands
4750: .Xr strftime 3
4751: specifiers.
1.683 nicm 4752: .Ql S:\& ,
4753: .Ql W:\&
1.618 nicm 4754: or
1.683 nicm 4755: .Ql P:\&
1.618 nicm 4756: will loop over each session, window or pane and insert the format once
1.619 nicm 4757: for each.
4758: For windows and panes, two comma-separated formats may be given:
4759: the second is used for the current window or active pane.
4760: For example, to get a list of windows formatted like the status line:
1.618 nicm 4761: .Bd -literal -offset indent
4762: #{W:#{E:window-status-format} ,#{E:window-status-current-format} }
4763: .Ed
1.817 nicm 4764: .Pp
4765: .Ql N:\&
4766: checks if a window (without any suffix or with the
4767: .Ql w
4768: suffix) or a session (with the
4769: .Ql s
4770: suffix) name exists, for example
4771: .Ql `N/w:foo`
4772: is replaced with 1 if a window named
4773: .Ql foo
4774: exists.
1.625 nicm 4775: .Pp
1.461 nicm 4776: A prefix of the form
1.683 nicm 4777: .Ql s/foo/bar/:\&
1.461 nicm 4778: will substitute
4779: .Ql foo
4780: with
4781: .Ql bar
4782: throughout.
1.664 nicm 4783: The first argument may be an extended regular expression and a final argument may be
4784: .Ql i
4785: to ignore case, for example
1.683 nicm 4786: .Ql s/a(.)/\e1x/i:\&
1.664 nicm 4787: would change
4788: .Ql abABab
4789: into
4790: .Ql bxBxbx .
1.431 nicm 4791: .Pp
1.671 nicm 4792: In addition, the last line of a shell command's output may be inserted using
1.431 nicm 4793: .Ql #() .
4794: For example,
4795: .Ql #(uptime)
4796: will insert the system's uptime.
4797: When constructing formats,
4798: .Nm
4799: does not wait for
4800: .Ql #()
4801: commands to finish; instead, the previous result from running the same command is used,
4802: or a placeholder if the command has not been run before.
1.543 nicm 4803: If the command hasn't exited, the most recent line of output will be used, but the status
4804: line will not be updated more than once a second.
1.431 nicm 4805: Commands are executed with the
4806: .Nm
4807: global environment set (see the
1.644 schwarze 4808: .Sx GLOBAL AND SESSION ENVIRONMENT
1.431 nicm 4809: section).
1.671 nicm 4810: .Pp
4811: An
4812: .Ql l
4813: specifies that a string should be interpreted literally and not expanded.
4814: For example
4815: .Ql #{l:#{?pane_in_mode,yes,no}}
