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

224: prefix key,
225: .Ql C-b
226: (Ctrl-b) by default, followed by a command key.
227: .Pp
1.172 nicm 228: The default command key bindings are:

352: .Pp
353: Key bindings may be changed with the

357: commands.
1.651 nicm 358: .Sh COMMAND PARSING AND EXECUTION
359: .Nm
360: supports a large number of commands which can be used to control its
361: behaviour.
362: Each command is named and can accept zero or more flags and arguments.
363: They may be bound to a key with the
364: .Ic bind-key
365: command or run from the shell prompt, a shell script, a configuration file or
366: the command prompt.
367: For example, the same
368: .Ic set-option
369: command run from the shell prompt, from
370: .Pa ~/.tmux.conf
371: and bound to a key may look like:
372: .Bd -literal -offset indent
373: $ tmux set-option -g status-style bg=cyan
374:
375: set-option -g status-style bg=cyan
376:
377: bind-key C set-option -g status-style bg=cyan
378: .Ed
379: .Pp
380: Here, the command name is
381: .Ql set-option ,
382: .Ql Fl g
383: is a flag and
384: .Ql status-style
385: and
386: .Ql bg=cyan
387: are arguments.
388: .Pp
389: .Nm
390: distinguishes between command parsing and execution.
391: In order to execute a command,
392: .Nm
393: needs it to be split up into its name and arguments.
394: This is command parsing.
395: If a command is run from the shell, the shell parses it; from inside
396: .Nm
397: or from a configuration file,
398: .Nm
399: does.
400: Examples of when
401: .Nm
402: parses commands are:
403: .Bl -dash -offset indent
404: .It
405: in a configuration file;
406: .It
407: typed at the command prompt (see
408: .Ic command-prompt ) ;
409: .It
410: given to
411: .Ic bind-key ;
412: .It
413: passed as arguments to
414: .Ic if-shell
415: or
416: .Ic confirm-before .
417: .El
418: .Pp
419: To execute commands, each client has a
420: .Ql command queue .
421: A global command queue not attached to any client is used on startup
422: for configuration files like
423: .Pa ~/.tmux.conf .
424: Parsed commands added to the queue are executed in order.
425: Some commands, like
426: .Ic if-shell
427: and
428: .Ic confirm-before ,
429: parse their argument to create a new command which is inserted immediately
430: after themselves.
431: This means that arguments can be parsed twice or more - once when the parent command (such as
432: .Ic if-shell )
433: is parsed and again when it parses and executes its command.
434: Commands like
435: .Ic if-shell ,
436: .Ic run-shell
437: and
438: .Ic display-panes
439: stop execution of subsequent commands on the queue until something happens -
440: .Ic if-shell
441: and
442: .Ic run-shell
443: until a shell command finishes and
444: .Ic display-panes
445: until a key is pressed.
446: For example, the following commands:
447: .Bd -literal -offset indent
448: new-session; new-window
449: if-shell "true" "split-window"
450: kill-session
451: .Ed
452: .Pp
453: Will execute
454: .Ic new-session ,
455: .Ic new-window ,
456: .Ic if-shell ,
457: the shell command
458: .Xr true 1 ,
459: .Ic new-window
460: and
461: .Ic kill-session
462: in that order.
463: .Pp
464: The
465: .Sx COMMANDS
466: section lists the
467: .Nm
468: commands and their arguments.
469: .Sh PARSING SYNTAX
470: This section describes the syntax of commands parsed by
471: .Nm ,
472: for example in a configuration file or at the command prompt.
473: Note the when commands are entered into the shell, they are parsed by the shell
474: - see for example
475: .Xr ksh 1
476: or
477: .Xr csh 1 .
478: .Pp
479: Each command is terminated by a newline or a semicolon (;).
480: Commands separated by semicolons together form a
481: .Ql command sequence
482: - if a command in the sequence encounters an error, no subsequent commands are
483: executed.
484: .Pp
485: Comments are marked by the unquoted # character - any remaining text after a
486: comment is ignored until the end of the line.
487: .Pp
488: If the last character of a line is \e, the line is joined with the following
489: line (the \e and the newline are completely removed).
490: This is called line continuation and applies both inside and outside quoted
1.656 nicm 491: strings and in comments, but not inside braces.
1.651 nicm 492: .Pp
1.655 nicm 493: Command arguments may be specified as strings surrounded by single (') quotes,
494: double quotes (") or braces ({}).
1.651 nicm 495: .\" "
496: This is required when the argument contains any special character.
1.655 nicm 497: Single and double quoted strings cannot span multiple lines except with line
498: continuation.
499: Braces can span multiple lines.
1.651 nicm 500: .Pp
501: Outside of quotes and inside double quotes, these replacements are performed:
502: .Bl -dash -offset indent
503: .It
504: Environment variables preceded by $ are replaced with their value from the
505: global environment (see the
506: .Sx GLOBAL AND SESSION ENVIRONMENT
507: section).
508: .It
509: A leading ~ or ~user is expanded to the home directory of the current or
510: specified user.
511: .It
512: \euXXXX or \euXXXXXXXX is replaced by the Unicode codepoint corresponding to
513: the given four or eight digit hexadecimal number.
514: .It
515: When preceded (escaped) by a \e, the following characters are replaced: \ee by
516: the escape character; \er by a carriage return; \en by a newline; and \et by a
517: tab.
1.660 nicm 518: .It
519: \eooo is replaced by a character of the octal value ooo.
520: Three octal digits are required, for example \e001.
521: The largest valid character is \e377.
522: .It
1.651 nicm 523: Any other characters preceded by \e are replaced by themselves (that is, the \e
524: is removed) and are not treated as having any special meaning - so for example
525: \e; will not mark a command sequence and \e$ will not expand an environment
526: variable.
527: .El
528: .Pp
1.655 nicm 529: Braces are similar to single quotes in that the text inside is taken literally
1.656 nicm 530: without any replacements but this also includes line continuation.
531: Braces can span multiple lines in which case a literal newline is included in the
532: string.
1.655 nicm 533: They are designed to avoid the need for additional escaping when passing a group
534: of
535: .Nm
536: or shell commands as an argument (for example to
537: .Ic if-shell
538: or
539: .Ic pipe-pane ) .
540: These two examples produce an identical command - note that no escaping is
541: needed when using {}:
542: .Bd -literal -offset indent
543: if-shell true {
544: display -p 'brace-dollar-foo: }$foo'
545: }
546:
547: if-shell true "\en display -p 'brace-dollar-foo: }\e$foo'\en"
548: .Ed
549: .Pp
550: Braces may be enclosed inside braces, for example:
551: .Bd -literal -offset indent
552: bind x if-shell "true" {
553: if-shell "true" {
554: display "true!"
555: }
556: }
557: .Ed
558: .Pp
1.651 nicm 559: Environment variables may be set by using the syntax
560: .Ql name=value ,
561: for example
562: .Ql HOME=/home/user .
563: Variables set during parsing are added to the global environment.
564: .Pp

1.57 jmc 603: .Sh COMMANDS
1.651 nicm 604: This section describes the commands supported by
1.57 jmc 605: .Nm .
606: Most commands accept the optional
607: .Fl t
1.432 nicm 608: (and sometimes
609: .Fl s )
1.57 jmc 610: argument with one of
611: .Ar target-client ,
612: .Ar target-session
613: .Ar target-window ,
614: or
615: .Ar target-pane .
616: These specify the client, session, window or pane which a command should affect.
1.423 nicm 617: .Pp
1.57 jmc 618: .Ar target-client
1.540 nicm 619: should be the name of the client,
620: typically the
1.57 jmc 621: .Xr pty 4
622: file to which the client is connected, for example either of
623: .Pa /dev/ttyp1
624: or
625: .Pa ttyp1
626: for the client attached to
627: .Pa /dev/ttyp1 .
1.423 nicm 628: If no client is specified,
629: .Nm
630: attempts to work out the client currently in use; if that fails, an error is
631: reported.
1.57 jmc 632: Clients may be listed with the
633: .Ic list-clients
634: command.
1.1 nicm 635: .Pp
1.57 jmc 636: .Ar target-session
1.423 nicm 637: is tried as, in order:
638: .Bl -enum -offset Ds
639: .It
640: A session ID prefixed with a $.
641: .It
642: An exact name of a session (as listed by the
1.57 jmc 643: .Ic list-sessions
1.423 nicm 644: command).
645: .It
646: The start of a session name, for example
647: .Ql mysess
648: would match a session named
649: .Ql mysession .
650: .It
651: An
1.57 jmc 652: .Xr fnmatch 3
1.423 nicm 653: pattern which is matched against the session name.
654: .El
655: .Pp
1.441 nicm 656: If the session name is prefixed with an
657: .Ql = ,
1.435 nicm 658: only an exact match is accepted (so
659: .Ql =mysess
660: will only match exactly
661: .Ql mysess ,
662: not
663: .Ql mysession ) .
1.441 nicm 664: .Pp
1.423 nicm 665: If a single session is found, it is used as the target session; multiple matches
1.57 jmc 666: produce an error.
667: If a session is omitted, the current session is used if available; if no
1.117 nicm 668: current session is available, the most recently used is chosen.

1.423 nicm 682: is looked for in order as:
683: .Bl -enum -offset Ds
684: .It
685: A special token, listed below.
686: .It
687: A window index, for example
688: .Ql mysession:1
689: is window 1 in session
690: .Ql mysession .
691: .It
692: A window ID, such as @1.
693: .It
694: An exact window name, such as

1.423 nicm 702: pattern matched against the window name.
703: .El
704: .Pp
1.435 nicm 705: Like sessions, a
706: .Ql =
707: prefix will do an exact match only.
1.57 jmc 708: An empty window name specifies the next unused index if appropriate (for
709: example the
710: .Ic new-window
711: and
712: .Ic link-window
713: commands)
714: otherwise the current window in

2586: .Ar command .
1.421 nicm 2587: Keys are bound in a key table.
2588: By default (without -T), the key is bound in
2589: the
2590: .Em prefix
2591: key table.
2592: This table is used for keys pressed after the prefix key (for example,
2593: by default
2594: .Ql c
2595: is bound to
2596: .Ic new-window
2597: in the

2701: .Sh OPTIONS
2702: The appearance and behaviour of
2703: .Nm

1.133 nicm 2705: There are three types of option:
2706: .Em server options ,
1.57 jmc 2707: .Em session options
2708: and
2709: .Em window options .
2710: .Pp
1.133 nicm 2711: The
2712: .Nm
2713: server has a set of global options which do not apply to any particular
2714: window or session.
2715: These are altered with the
2716: .Ic set-option
2717: .Fl s
2718: command, or displayed with the
2719: .Ic show-options
2720: .Fl s
2721: command.
2722: .Pp
2723: In addition, each individual session may have a set of session options, and
2724: there is a separate set of global session options.
1.57 jmc 2725: Sessions which do not have a particular option configured inherit the value
2726: from the global session options.
2727: Session options are set or unset with the
2728: .Ic set-option
2729: command and may be listed with the
2730: .Ic show-options
2731: command.
1.133 nicm 2732: The available server and session options are listed under the
1.57 jmc 2733: .Ic set-option
2734: command.
2735: .Pp
2736: Similarly, a set of window options is attached to each window, and there is
2737: a set of global window options from which any unset options are inherited.
2738: Window options are altered with the
2739: .Ic set-window-option
2740: command and can be listed with the
2741: .Ic show-window-options
2742: command.
2743: All window options are documented with the
2744: .Ic set-window-option
2745: command.
1.318 nicm 2746: .Pp
2747: .Nm
2748: also supports user options which are prefixed with a
2749: .Ql \&@ .
1.321 jmc 2750: User options may have any name, so long as they are prefixed with
2751: .Ql \&@ ,
1.318 nicm 2752: and be set to any string.
1.418 nicm 2753: For example:
1.318 nicm 2754: .Bd -literal -offset indent
2755: $ tmux setw -q @foo "abc123"
2756: $ tmux showw -v @foo
2757: abc123
2758: .Ed
1.57 jmc 2759: .Pp
2760: Commands which set options are as follows:
2761: .Bl -tag -width Ds
1.1 nicm 2762: .It Xo Ic set-option
1.550 nicm 2763: .Op Fl aFgoqsuw
1.129 nicm 2764: .Op Fl t Ar target-session | Ar target-window
1.1 nicm 2765: .Ar option Ar value
2766: .Xc
2767: .D1 (alias: Ic set )
1.133 nicm 2768: Set a window option with
2769: .Fl w
2770: (equivalent to the
2771: .Ic set-window-option
2772: command),
2773: a server option with
2774: .Fl s ,
2775: otherwise a session option.
1.637 nicm 2776: If the option is not a user option,
2777: .Fl w
2778: and
2779: .Fl s
2780: are unnecessary -
2781: .Nm
2782: will infer the type from the option name.
1.133 nicm 2783: If
2784: .Fl g
1.433 nicm 2785: is given, the global session or window option is set.
1.637 nicm 2786: .Pp
1.550 nicm 2787: .Fl F
2788: expands formats in the option value.
1.1 nicm 2789: The
2790: .Fl u
2791: flag unsets an option, so a session inherits the option from the global
1.433 nicm 2792: options (or with
2793: .Fl g ,
2794: restores a global option to the default).
1.336 nicm 2795: .Pp
2796: The
2797: .Fl o
1.446 nicm 2798: flag prevents setting an option that is already set and the
1.281 nicm 2799: .Fl q
1.446 nicm 2800: flag suppresses errors about unknown or ambiguous options.
1.281 nicm 2801: .Pp
1.378 nicm 2802: With
2803: .Fl a ,
2804: and if the option expects a string or a style,
2805: .Ar value
2806: is appended to the existing setting.
2807: For example:
2808: .Bd -literal -offset indent
2809: set -g status-left "foo"
2810: set -ag status-left "bar"
2811: .Ed
2812: .Pp
2813: Will result in
2814: .Ql foobar .
2815: And:
2816: .Bd -literal -offset indent
2817: set -g status-style "bg=red"
2818: set -ag status-style "fg=blue"
2819: .Ed
2820: .Pp
2821: Will result in a red background
2822: .Em and
2823: blue foreground.
2824: Without
2825: .Fl a ,
2826: the result would be the default background and a blue foreground.
2827: .Pp
1.133 nicm 2828: Available window options are listed under
2829: .Ic set-window-option .
1.274 nicm 2830: .Pp
2831: .Ar value
2832: depends on the option and may be a number, a string, or a flag (on, off, or
2833: omitted to toggle).
1.133 nicm 2834: .Pp
2835: Available server options are:
2836: .Bl -tag -width Ds
1.198 nicm 2837: .It Ic buffer-limit Ar number
2838: Set the number of buffers; as new buffers are added to the top of the stack,
2839: old ones are removed from the bottom if necessary to maintain this maximum
2840: length.
1.526 nicm 2841: .It Xo Ic command-alias[]
2842: .Ar name=value
2843: .Xc
2844: This is an array of custom aliases for commands.
2845: If an unknown command matches
2846: .Ar name ,
2847: it is replaced with
2848: .Ar value .
2849: For example, after:
2850: .Pp
1.565 nicm 2851: .Dl set -s command-alias[100] zoom='resize-pane -Z'
1.526 nicm 2852: .Pp
2853: Using:
2854: .Pp
2855: .Dl zoom -t:.1
2856: .Pp
2857: Is equivalent to:
2858: .Pp
2859: .Dl resize-pane -Z -t:.1
2860: .Pp
2861: Note that aliases are expanded when a command is parsed rather than when it is
2862: executed, so binding an alias with
2863: .Ic bind-key
2864: will bind the expanded form.
1.425 nicm 2865: .It Ic default-terminal Ar terminal
2866: Set the default terminal for new windows created in this session - the
2867: default value of the
2868: .Ev TERM
2869: environment variable.
2870: For
2871: .Nm
2872: to work correctly, this
2873: .Em must
2874: be set to
2875: .Ql screen ,
2876: .Ql tmux
2877: or a derivative of them.
1.239 nicm 2878: .It Ic escape-time Ar time
2879: Set the time in milliseconds for which
2880: .Nm
2881: waits after an escape is input to determine if it is part of a function or meta
2882: key sequences.
2883: The default is 500 milliseconds.
1.592 nicm 2884: .It Xo Ic exit-empty
2885: .Op Ic on | off
2886: .Xc

1.239 nicm 2889: .It Xo Ic exit-unattached
2890: .Op Ic on | off
2891: .Xc
2892: If enabled, the server will exit when there are no attached clients.
1.362 nicm 2893: .It Xo Ic focus-events
2894: .Op Ic on | off
2895: .Xc
2896: When enabled, focus events are requested from the terminal if supported and
2897: passed through to applications running in
2898: .Nm .
2899: Attached clients should be detached and attached again after changing this
2900: option.
1.445 nicm 2901: .It Ic history-file Ar path
2902: If not empty, a file to which
2903: .Nm
2904: will write command prompt history on exit and load it from on start.
1.384 nicm 2905: .It Ic message-limit Ar number
2906: Set the number of error or information messages to save in the message log for

2921: .Pp
1.556 nicm 2922: If set to
2923: .Ic on ,
2924: .Nm

2926: the terminal clipboard.
2927: If set to

2929: .Nm
2930: will attempt to set the terminal clipboard but ignore attempts

2939: .Pp
1.228 nicm 2940: Note that this feature needs to be enabled in

3740: .Pp
1.640 nicm 3741: Hooks are stored as array options, members of the array are executed in

3758: Setting a hook without specifying an array index clears the hook and sets the
3759: first member of the array.
3760: .Pp
1.505 nicm 3761: A command's after
3762: hook is run after it completes, except when the command is run as part of a hook
1.483 nicm 3763: itself.
1.505 nicm 3764: They are named with an
1.483 nicm 3765: .Ql after-

4051: .Pp
1.453 nicm 4052: Prefixing a time variable with
4053: .Ql t:

1.454 jmc 4057: .Ql 1445765102 ,
1.453 nicm 4058: .Ql #{t:window_activity}

4069: of the variable respectively.
1.610 nicm 4070: .Ql q:
4071: will escape
4072: .Xr sh 1
4073: special characters.
1.617 nicm 4074: .Ql E:
4075: will expand the format twice, for example
4076: .Ql #{E:status-left}
4077: is the result of expanding the content of the
4078: .Ic status-left
4079: option rather than the content itself.
1.620 nicm 4080: .Ql T:
4081: is like
4082: .Ql E:
4083: but also expands
4084: .Xr strftime 3

4088: or
4089: .Ql P:
4090: will loop over each session, window or pane and insert the format once
1.619 nicm 4091: for each.
4092: For windows and panes, two comma-separated formats may be given:
4093: the second is used for the current window or active pane.
4094: For example, to get a list of windows formatted like the status line:
1.618 nicm 4095: .Bd -literal -offset indent
4096: #{W:#{E:window-status-format} ,#{E:window-status-current-format} }
4097: .Ed
1.625 nicm 4098: .Pp
1.461 nicm 4099: A prefix of the form
4100: .Ql s/foo/bar/:
4101: will substitute
4102: .Ql foo
4103: with
4104: .Ql bar
4105: throughout.
1.431 nicm 4106: .Pp
4107: In addition, the first line of a shell command's output may be inserted using
4108: .Ql #() .
4109: For example,
4110: .Ql #(uptime)
4111: will insert the system's uptime.
4112: When constructing formats,
4113: .Nm
4114: does not wait for
4115: .Ql #()
4116: commands to finish; instead, the previous result from running the same command is used,
4117: or a placeholder if the command has not been run before.
1.543 nicm 4118: If the command hasn't exited, the most recent line of output will be used, but the status
4119: line will not be updated more than once a second.
1.431 nicm 4120: Commands are executed with the
