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
1.6 jmc 154: Prevent the server sending various informational messages, for example when
1.4 sobrado 155: window flags are altered.
1.1 nicm 156: .It Fl S Ar socket-path
157: Specify a full alternative path to the server socket.
158: If
159: .Fl S
160: is specified, the default socket directory is not used and any
161: .Fl L
162: flag is ignored.
163: .It Fl u
164: .Nm
1.14 nicm 165: attempts to guess if the terminal is likely to support UTF-8 by checking the
166: first of the
167: .Ev LC_ALL ,
168: .Ev LC_CTYPE
169: and
1.2 nicm 170: .Ev LANG
1.14 nicm 171: environment variables to be set for the string "UTF-8".
1.5 nicm 172: This is not always correct: the
1.2 nicm 173: .Fl u
174: flag explicitly informs
175: .Nm
1.6 jmc 176: that UTF-8 is supported.
1.33 nicm 177: .Pp
178: If the server is started from a client passed
179: .Fl u
180: or where UTF-8 is detected, the
181: .Ic utf8
182: and
183: .Ic status-utf8
184: options are enabled in the global window and session options respectively.
1.1 nicm 185: .It Fl v
186: Request verbose logging.
187: This option may be specified multiple times for increasing verbosity.
188: Log messages will be saved into
189: .Pa tmux-client-PID.log
190: and
191: .Pa tmux-server-PID.log
192: files in the current directory, where
193: .Em PID
1.6 jmc 194: is the PID of the server or client process.
1.1 nicm 195: .It Ar command Op Ar flags
196: This specifies one of a set of commands used to control
197: .Nm ,
1.6 jmc 198: as described in the following sections.
1.59 jmc 199: If no commands are specified, the
1.1 nicm 200: .Ic new-session
201: command is assumed.
1.57 jmc 202: .El
1.64 nicm 203: .Sh KEY BINDINGS
204: .Nm
205: may be controlled from an attached client by using a key combination of a
206: prefix key,
207: .Ql C-b
208: (Ctrl-b) by default, followed by a command key.
209: .Pp
210: Some of the default key bindings are:
211: .Pp
1.67 jmc 212: .Bl -tag -width Ds -offset indent -compact
1.64 nicm 213: .It c
1.65 nicm 214: Create a new window.
1.64 nicm 215: .It d
1.65 nicm 216: Detach the current client.
1.64 nicm 217: .It l
1.65 nicm 218: Move to the previously selected window.
1.64 nicm 219: .It n
1.65 nicm 220: Change to the next window.
1.64 nicm 221: .It p
1.65 nicm 222: Change to the previous window.
223: .It &
224: Kill the current window.
225: .It ,
226: Rename the current window.
1.64 nicm 227: .It \&?
1.65 nicm 228: List all key bindings.
1.64 nicm 229: .El
230: .Pp
231: A complete list may be obtained with the
232: .Ic list-keys
233: command (bound to
234: .Ql \&?
235: by default).
236: Key bindings may be changed with the
237: .Ic bind-key
238: and
239: .Ic unbind-key
240: commands.
1.57 jmc 241: .Sh COMMANDS
242: This section contains a list of the commands supported by
243: .Nm .
244: Most commands accept the optional
245: .Fl t
246: argument with one of
247: .Ar target-client ,
248: .Ar target-session
249: .Ar target-window ,
250: or
251: .Ar target-pane .
252: These specify the client, session, window or pane which a command should affect.
253: .Ar target-client
254: is the name of the
255: .Xr pty 4
256: file to which the client is connected, for example either of
257: .Pa /dev/ttyp1
258: or
259: .Pa ttyp1
260: for the client attached to
261: .Pa /dev/ttyp1 .
262: If no client is specified, the current client is chosen, if possible, or an
263: error is reported.
264: Clients may be listed with the
265: .Ic list-clients
266: command.
1.1 nicm 267: .Pp
1.57 jmc 268: .Ar target-session
269: is either the name of a session (as listed by the
270: .Ic list-sessions
271: command) or the name of a client with the same syntax as
272: .Ar target-client ,
273: in which case the session attached to the client is used.
274: When looking for the session name,
275: .Nm
276: initially searches for an exact match; if none is found, the session names
277: are checked for any for which
278: .Ar target-session
279: is a prefix or for which it matches as an
280: .Xr fnmatch 3
281: pattern.
282: If a single match is found, it is used as the target session; multiple matches
283: produce an error.
284: If a session is omitted, the current session is used if available; if no
1.117 nicm 285: current session is available, the most recently used is chosen.
1.1 nicm 286: .Pp
1.57 jmc 287: .Ar target-window
288: specifies a window in the form
289: .Em session Ns \&: Ns Em window .
290: .Em session
291: follows the same rules as for
292: .Ar target-session ,
293: and
294: .Em window
295: is looked for in order: as a window index, for example mysession:1; as an exact
296: window name, such as mysession:mywindow; then as an
297: .Xr fnmatch 3
298: pattern or the start of a window name, such as mysession:mywin* or
299: mysession:mywin.
300: An empty window name specifies the next unused index if appropriate (for
301: example the
302: .Ic new-window
303: and
304: .Ic link-window
305: commands)
306: otherwise the current window in
307: .Em session
308: is chosen.
309: When the argument does not contain a colon,
310: .Nm
311: first attempts to parse it as window; if that fails, an attempt is made to
312: match a session.
1.1 nicm 313: .Pp
1.57 jmc 314: .Ar target-pane
315: takes a similar form to
316: .Ar target-window
317: but with the optional addition of a period followed by a pane index, for
318: example: mysession:mywindow.1.
319: If the pane index is omitted, the currently active pane in the specified
320: window is used.
321: If neither a colon nor period appears,
1.13 nicm 322: .Nm
1.57 jmc 323: first attempts to use the argument as a pane index; if that fails, it is looked
324: up as for
325: .Ar target-window .
1.15 jmc 326: .Pp
1.57 jmc 327: Multiple commands may be specified together as part of a
328: .Em command sequence .
329: Each command should be separated by spaces and a semicolon;
330: commands are executed sequentially from left to right.
331: A literal semicolon may be included by escaping it with a backslash (for
332: example, when specifying a command sequence to
333: .Ic bind-key ) .
1.13 nicm 334: .Pp
1.57 jmc 335: Examples include:
1.13 nicm 336: .Bd -literal -offset indent
1.57 jmc 337: refresh-client -t/dev/ttyp2
338:
339: rename-session -tfirst newname

358: If
359: .Fl d
360: is specified, any other clients attached to the session are detached.
1.13 nicm 361: .Pp
1.57 jmc 362: If no server is started,
363: .Ic attach-session
364: will attempt to start it; this will fail unless sessions are created in the
365: configuration file.
366: .It Ic detach-client Op Fl t Ar target-client

1.57 jmc 419: .Ar command
420: are the name of and command to execute in the initial window.
1.68 nicm 421: .Pp
422: If run from a terminal, any

424: special characters are saved and used for new windows in the new session.
1.101 nicm 425: .Pp
426: If
427: .Fl t
428: is given, the new session is
429: .Em grouped
430: with
431: .Ar target-session .
432: This means they share the same set of windows - all windows from
433: .Ar target-session
434: are linked to the new session and any subsequent new windows or windows being
435: closed are applied to both sessions.
436: The current and previous window and any session options remain independent and
437: either session may be killed without affecting the other.
438: Giving

1.18 nicm 1246: is specified, the global session option is set.
1.1 nicm 1247: The
