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