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.
101: .It Fl 8
102: Like
103: .Fl 2 ,
1.6 jmc 104: but indicates that the terminal supports 88 colours.
1.91 nicm 105: .It Fl c Ar shell-command
106: Execute
107: .Ar shell-command
108: using the default shell.
109: If necessary, the
110: .Nm
111: server will be started to retrieve the
112: .Ic default-shell
113: option.
1.1 nicm 114: .It Fl f Ar file
115: Specify an alternative configuration file.
116: By default,
117: .Nm
1.26 nicm 118: loads the system configuration file from
119: .Pa /etc/tmux.conf ,
120: if present, then looks for a user configuration file at
1.1 nicm 121: .Pa ~/.tmux.conf .
122: The configuration file is a set of
123: .Nm
124: commands which are executed in sequence when the server is first started.
1.61 nicm 125: .Pp
126: If a command in the configuration file fails,
127: .Nm
128: will report an error and exit without executing further commands.
1.82 nicm 129: .It Fl l
130: Behave as a login shell.
131: This flag currently has no effect and is for compatibility with other shells
132: when using tmux as a login shell.
1.1 nicm 133: .It Fl L Ar socket-name
134: .Nm
135: stores the server socket in a directory under
136: .Pa /tmp ;
137: the default socket is named
138: .Em default .
139: This option allows a different socket name to be specified, allowing several
140: independent
141: .Nm
142: servers to be run.
143: Unlike
144: .Fl S
145: a full path is not necessary: the sockets are all created in the same
146: directory.
1.2 nicm 147: .Pp
148: If the socket is accidentally removed, the
1.6 jmc 149: .Dv SIGUSR1
1.2 nicm 150: signal may be sent to the
151: .Nm
152: server process to recreate it.
1.4 sobrado 153: .It Fl q
1.133 nicm 154: Set the
155: .Ic quiet
156: server option to prevent the server sending various informational messages.
1.1 nicm 157: .It Fl S Ar socket-path
158: Specify a full alternative path to the server socket.
159: If
160: .Fl S
161: is specified, the default socket directory is not used and any
162: .Fl L
163: flag is ignored.
164: .It Fl u
165: .Nm
1.14 nicm 166: attempts to guess if the terminal is likely to support UTF-8 by checking the
167: first of the
168: .Ev LC_ALL ,
169: .Ev LC_CTYPE
170: and
1.2 nicm 171: .Ev LANG
1.14 nicm 172: environment variables to be set for the string "UTF-8".
1.5 nicm 173: This is not always correct: the
1.2 nicm 174: .Fl u
175: flag explicitly informs
176: .Nm
1.6 jmc 177: that UTF-8 is supported.
1.33 nicm 178: .Pp
179: If the server is started from a client passed
180: .Fl u
181: or where UTF-8 is detected, the
182: .Ic utf8
183: and
184: .Ic status-utf8
185: options are enabled in the global window and session options respectively.
1.1 nicm 186: .It Fl v
187: Request verbose logging.
188: This option may be specified multiple times for increasing verbosity.
189: Log messages will be saved into
190: .Pa tmux-client-PID.log
191: and
192: .Pa tmux-server-PID.log
193: files in the current directory, where
194: .Em PID
1.6 jmc 195: is the PID of the server or client process.
1.1 nicm 196: .It Ar command Op Ar flags
197: This specifies one of a set of commands used to control
198: .Nm ,
1.6 jmc 199: as described in the following sections.
1.59 jmc 200: If no commands are specified, the
1.1 nicm 201: .Ic new-session
202: command is assumed.
1.57 jmc 203: .El
1.64 nicm 204: .Sh KEY BINDINGS
205: .Nm
206: may be controlled from an attached client by using a key combination of a
207: prefix key,
208: .Ql C-b
209: (Ctrl-b) by default, followed by a command key.
210: .Pp
211: Some of the default key bindings are:
212: .Pp
1.67 jmc 213: .Bl -tag -width Ds -offset indent -compact
1.64 nicm 214: .It c
1.65 nicm 215: Create a new window.
1.64 nicm 216: .It d
1.65 nicm 217: Detach the current client.
1.64 nicm 218: .It l
1.65 nicm 219: Move to the previously selected window.
1.64 nicm 220: .It n
1.65 nicm 221: Change to the next window.
1.64 nicm 222: .It p
1.65 nicm 223: Change to the previous window.
224: .It &
225: Kill the current window.
226: .It ,
227: Rename the current window.
1.64 nicm 228: .It \&?
1.65 nicm 229: List all key bindings.
1.64 nicm 230: .El
231: .Pp
232: A complete list may be obtained with the
233: .Ic list-keys
234: command (bound to
235: .Ql \&?
236: by default).
237: Key bindings may be changed with the
238: .Ic bind-key
239: and
240: .Ic unbind-key
241: commands.
1.57 jmc 242: .Sh COMMANDS
243: This section contains a list of the commands supported by
244: .Nm .
245: Most commands accept the optional
246: .Fl t
247: argument with one of
248: .Ar target-client ,
249: .Ar target-session
250: .Ar target-window ,
251: or
252: .Ar target-pane .
253: These specify the client, session, window or pane which a command should affect.
254: .Ar target-client
255: is the name of the
256: .Xr pty 4
257: file to which the client is connected, for example either of
258: .Pa /dev/ttyp1
259: or
260: .Pa ttyp1
261: for the client attached to
262: .Pa /dev/ttyp1 .
263: If no client is specified, the current client is chosen, if possible, or an
264: error is reported.
265: Clients may be listed with the
266: .Ic list-clients
267: command.
1.1 nicm 268: .Pp
1.57 jmc 269: .Ar target-session
270: is either the name of a session (as listed by the
271: .Ic list-sessions
272: command) or the name of a client with the same syntax as
273: .Ar target-client ,
274: in which case the session attached to the client is used.
275: When looking for the session name,
276: .Nm
277: initially searches for an exact match; if none is found, the session names
278: are checked for any for which
279: .Ar target-session
280: is a prefix or for which it matches as an
281: .Xr fnmatch 3
282: pattern.
283: If a single match is found, it is used as the target session; multiple matches
284: produce an error.
285: If a session is omitted, the current session is used if available; if no
1.117 nicm 286: current session is available, the most recently used is chosen.
1.1 nicm 287: .Pp
1.57 jmc 288: .Ar target-window
289: specifies a window in the form
290: .Em session Ns \&: Ns Em window .
291: .Em session
292: follows the same rules as for
293: .Ar target-session ,
294: and
295: .Em window
296: is looked for in order: as a window index, for example mysession:1; as an exact
297: window name, such as mysession:mywindow; then as an
298: .Xr fnmatch 3
299: pattern or the start of a window name, such as mysession:mywin* or
300: mysession:mywin.
301: An empty window name specifies the next unused index if appropriate (for
302: example the
303: .Ic new-window
304: and
305: .Ic link-window
306: commands)
307: otherwise the current window in
308: .Em session
309: is chosen.
1.140 nicm 310: The special character
311: .Ql \&!
312: uses the last (previously current) window, or
313: .Ql +
314: and
315: .Ql -
316: are the next window or the previous window by number.
1.57 jmc 317: When the argument does not contain a colon,
318: .Nm
319: first attempts to parse it as window; if that fails, an attempt is made to
320: match a session.
1.1 nicm 321: .Pp
1.57 jmc 322: .Ar target-pane
323: takes a similar form to
324: .Ar target-window
325: but with the optional addition of a period followed by a pane index, for
326: example: mysession:mywindow.1.
327: If the pane index is omitted, the currently active pane in the specified
328: window is used.
329: If neither a colon nor period appears,
1.13 nicm 330: .Nm
1.57 jmc 331: first attempts to use the argument as a pane index; if that fails, it is looked
332: up as for
333: .Ar target-window .
1.132 nicm 334: One of the strings
335: .Em top ,
336: .Em bottom ,
337: .Em left ,
338: .Em right ,
339: .Em top-left ,
340: .Em top-right ,
341: .Em bottom-left or
342: .Em bottom-right
343: may be used instead of a pane index.
1.15 jmc 344: .Pp
1.57 jmc 345: Multiple commands may be specified together as part of a
346: .Em command sequence .
347: Each command should be separated by spaces and a semicolon;
348: commands are executed sequentially from left to right.
349: A literal semicolon may be included by escaping it with a backslash (for
350: example, when specifying a command sequence to
351: .Ic bind-key ) .
1.13 nicm 352: .Pp
1.57 jmc 353: Examples include:
1.13 nicm 354: .Bd -literal -offset indent
1.57 jmc 355: refresh-client -t/dev/ttyp2
356:
357: rename-session -tfirst newname

376: If
377: .Fl d
378: is specified, any other clients attached to the session are detached.
1.13 nicm 379: .Pp
1.57 jmc 380: If no server is started,
381: .Ic attach-session
382: will attempt to start it; this will fail unless sessions are created in the
383: configuration file.
384: .It Ic detach-client Op Fl t Ar target-client

442: special characters are saved and used for new windows in the new session.
1.101 nicm 443: .Pp
444: If
445: .Fl t
446: is given, the new session is
447: .Em grouped
448: with
449: .Ar target-session .
450: This means they share the same set of windows - all windows from
451: .Ar target-session
452: are linked to the new session and any subsequent new windows or windows being
453: closed are applied to both sessions.
454: The current and previous window and any session options remain independent and
455: either session may be killed without affecting the other.
456: Giving
