.Sh DESCRIPTION
|
|
.Nm
|
|
is a terminal multiplexer:
|
|
it enables a number of terminals to be created, accessed, and
|
|
controlled from a single screen.
|
|
.Nm
|
|
may be detached from a screen
|
|
and continue running in the background,
|
|
then later reattached.
|
|
.Pp
|
|
When
|
|
.Nm
|
|
is started it creates a new
|
|
.Em session
|
|
with a single
|
|
.Em window
|
|
and displays it on screen.
|
|
A status line at the bottom of the screen
|
|
shows information on the current session
|
|
and is used to enter interactive commands.
|
|
.Pp
|
|
A session is a single collection of
|
|
.Em pseudo terminals
|
|
under the management of
|
|
.Nm .
|
|
Each session has one or more
|
|
windows linked to it.
|
|
A window occupies the entire screen
|
|
and may be split into rectangular panes,
|
|
each of which is a separate pseudo terminal
|
|
(the
|
|
.Xr pty 4
|
|
manual page documents the technical details of pseudo terminals).
|
|
Any number of
|
|
.Nm
|
|
instances may connect to the same session,
|
|
and any number of windows may be present in the same session.
|
|
Once all sessions are killed,
|
|
.Nm
|
|
exits.
|
|
.Pp
|
|
Each session is persistent and will survive accidental disconnection
|
|
(such as
|
|
.Xr ssh 1
|
|
connection timeout) or intentional detaching (with the
|
|
.Ql C-b d
|
|
key strokes).
|
|
.Nm
|
|
may be reattached using:
|
|
.Pp
|
|
.Dl $ tmux attach
|
|
.Pp
|
|
In
|
|
.Nm ,
|
|
a session is displayed on screen by a
|
|
.Em client
|
|
and all sessions are managed by a single
|
|
.Em server .
|
|
The server and each client are separate processes which communicate through a
|
|
socket in
|
|
.Pa /tmp .
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width "XXXXXXXXXXXX"
|
|
.It Fl 2
|
|
Force
|
|
.Nm
|
|
to assume the terminal supports 256 colours.
|
|
.It Fl 8
|
|
Like
|
|
.Fl 2 ,
|
|
but indicates that the terminal supports 88 colours.
|
|
.It Fl d
|
|
Force
|
|
.Nm
|
|
to assume the terminal supports default colours.
|
|
.It Fl f Ar file
|
|
Specify an alternative configuration file.
|
|
By default,
|
|
.Nm
|
|
loads the system configuration file from
|
|
.Pa /etc/tmux.conf ,
|
|
if present, then looks for a user configuration file at
|
|
.Pa ~/.tmux.conf .
|
|
The configuration file is a set of
|
|
.Nm
|
|
commands which are executed in sequence when the server is first started.
|
|
.Pp
|
|
If a command in the configuration file fails,
|
|
.Nm
|
|
will report an error and exit without executing further commands.
|
|
.It Fl l
|
|
Behave as a login shell.
|
|
This flag currently has no effect and is for compatibility with other shells
|
|
when using tmux as a login shell.
|
|
.It Fl L Ar socket-name
|
|
.Nm
|
|
stores the server socket in a directory under
|
|
.Pa /tmp ;
|
|
the default socket is named
|
|
.Em default .
|
|
This option allows a different socket name to be specified, allowing several
|
|
independent
|
|
.Nm
|
|
servers to be run.
|
|
Unlike
|
|
.Fl S
|
|
a full path is not necessary: the sockets are all created in the same
|
|
directory.
|
|
.Pp
|
|
If the socket is accidentally removed, the
|
|
.Dv SIGUSR1
|
|
signal may be sent to the
|
|
.Nm
|
|
server process to recreate it.
|
|
.It Fl q
|
|
Prevent the server sending various informational messages, for example when
|
|
window flags are altered.
|
|
.It Fl S Ar socket-path
|
|
Specify a full alternative path to the server socket.
|
|
If
|
|
.Fl S
|
|
is specified, the default socket directory is not used and any
|
|
.Fl L
|
|
flag is ignored.
|
|
.It Fl U
|
|
Unlock the server.
|
|
.It Fl u
|
|
.Nm
|
|
attempts to guess if the terminal is likely to support UTF-8 by checking the
|
|
first of the
|
|
.Ev LC_ALL ,
|
|
.Ev LC_CTYPE
|
|
and
|
|
.Ev LANG
|
|
environment variables to be set for the string "UTF-8".
|
|
This is not always correct: the
|
|
.Fl u
|
|
flag explicitly informs
|
|
.Nm
|
|
that UTF-8 is supported.
|
|
.Pp
|
|
If the server is started from a client passed
|
|
.Fl u
|
|
or where UTF-8 is detected, the
|
|
.Ic utf8
|
|
and
|
|
.Ic status-utf8
|
|
options are enabled in the global window and session options respectively.
|
|
.It Fl v
|
|
Request verbose logging.
|
|
This option may be specified multiple times for increasing verbosity.
|
|
Log messages will be saved into
|
|
.Pa tmux-client-PID.log
|
|
and
|
|
.Pa tmux-server-PID.log
|
|
files in the current directory, where
|
|
.Em PID
|
|
is the PID of the server or client process.
|
|
.It Ar command Op Ar flags
|
|
This specifies one of a set of commands used to control
|
|
.Nm ,
|
|
as described in the following sections.
|
|
If no commands are specified, the
|
|
.Ic new-session
|
|
command is assumed.
|
|
.El
|
|
.Sh KEY BINDINGS
|
|
.Nm
|
|
may be controlled from an attached client by using a key combination of a
|
|
prefix key,
|
|
.Ql C-b
|
|
(Ctrl-b) by default, followed by a command key.
|
|
.Pp
|
|
Some of the default key bindings are:
|
|
.Pp
|
|
.Bl -tag -width Ds -offset indent -compact
|
|
.It c
|
|
Create a new window.
|
|
.It d
|
|
Detach the current client.
|
|
.It l
|
|
Move to the previously selected window.
|
|
.It n
|
|
Change to the next window.
|
|
.It p
|
|
Change to the previous window.
|
|
.It &
|
|
Kill the current window.
|
|
.It ,
|
|
Rename the current window.
|
|
.It \&?
|
|
List all key bindings.
|
|
.El
|
|
.Pp
|
|
A complete list may be obtained with the
|
|
.Ic list-keys
|
|
command (bound to
|
|
.Ql \&?
|
|
by default).
|
|
Key bindings may be changed with the
|
|
.Ic bind-key
|
|
and
|
|
.Ic unbind-key
|
|
commands.
|
|
.Sh COMMANDS
|
|
This section contains a list of the commands supported by
|
|
.Nm .
|
|
Most commands accept the optional
|
|
.Fl t
|
|
argument with one of
|
|
.Ar target-client ,
|
|
.Ar target-session
|
|
.Ar target-window ,
|
|
or
|
|
.Ar target-pane .
|
|
These specify the client, session, window or pane which a command should affect.
|
|
.Ar target-client
|
|
is the name of the
|
|
.Xr pty 4
|
|
file to which the client is connected, for example either of
|
|
.Pa /dev/ttyp1
|
|
or
|
|
.Pa ttyp1
|
|
for the client attached to
|
|
.Pa /dev/ttyp1 .
|
|
If no client is specified, the current client is chosen, if possible, or an
|
|
error is reported.
|
|
Clients may be listed with the
|
|
.Ic list-clients
|
|
command.
|
|
.Pp
|
|
.Ar target-session
|
|
is either the name of a session (as listed by the
|
|
.Ic list-sessions
|
|
command) or the name of a client with the same syntax as
|
|
.Ar target-client ,
|
|
in which case the session attached to the client is used.
|
|
When looking for the session name,
|
|
.Nm
|
|
initially searches for an exact match; if none is found, the session names
|
|
are checked for any for which
|
|
.Ar target-session
|
|
is a prefix or for which it matches as an
|
|
.Xr fnmatch 3
|
|
pattern.
|
|
If a single match is found, it is used as the target session; multiple matches
|
|
produce an error.
|
|
If a session is omitted, the current session is used if available; if no
|
|
current session is available, the most recently created is chosen.
|
|
.Pp
|
|
.Ar target-window
|
|
specifies a window in the form
|
|
.Em session Ns \&: Ns Em window .
|
|
.Em session
|
|
follows the same rules as for
|
|
.Ar target-session ,
|
|
and
|
|
.Em window
|
|
is looked for in order: as a window index, for example mysession:1; as an exact
|
|
window name, such as mysession:mywindow; then as an
|
|
.Xr fnmatch 3
|
|
pattern or the start of a window name, such as mysession:mywin* or
|
|
mysession:mywin.
|
|
An empty window name specifies the next unused index if appropriate (for
|
|
example the
|
|
.Ic new-window
|
|
and
|
|
.Ic link-window
|
|
commands)
|
|
otherwise the current window in
|
|
.Em session
|
|
is chosen.
|
|
When the argument does not contain a colon,
|
|
.Nm
|
|
first attempts to parse it as window; if that fails, an attempt is made to
|
|
match a session.
|
|
.Pp
|
|
.Ar target-pane
|
|
takes a similar form to
|
|
.Ar target-window
|
|
but with the optional addition of a period followed by a pane index, for
|
|
example: mysession:mywindow.1.
|
|
If the pane index is omitted, the currently active pane in the specified
|
|
window is used.
|
|
If neither a colon nor period appears,
|
|
.Nm
|
|
first attempts to use the argument as a pane index; if that fails, it is looked
|
|
up as for
|
|
.Ar target-window .
|
|
.Pp
|
|
Multiple commands may be specified together as part of a
|
|
.Em command sequence .
|
|
Each command should be separated by spaces and a semicolon;
|
|
commands are executed sequentially from left to right.
|
|
A literal semicolon may be included by escaping it with a backslash (for
|
|
example, when specifying a command sequence to
|
|
.Ic bind-key ) .
|
|
.Pp
|
|
Examples include:
|
|
.Bd -literal -offset indent
|
|
refresh-client -t/dev/ttyp2
|
|
|
|
rename-session -tfirst newname
|
|

.Nm
|
|
window may be in one of several modes.
|
|
The default permits direct access to the terminal attached to the window.
|
|
The others are:
|
|
.Bl -tag -width Ds
|
|
.It Em output mode
|
|
This is entered when a command which produces output, such as
|
|
.Ic list-keys ,
|
|
is executed from a key binding.
|
|
.It Em scroll mode
|
|
This is entered with the

|
command (bound to
|
|
.Ql =
|
|
by default) and permits the window history buffer to be inspected.
|
|
.It Em copy mode
|
|
This permits a section of a window or its history to be copied to a
|
|
.Em paste buffer
|
|
for later insertion into another window.
|
|
This mode is entered with the
|
|
.Ic copy-mode
|
|
command, bound to
|
|
.Ql [
|
|
by default.

These key bindings are defined in a set of named tables:
|
|
.Em vi-edit
|
|
and
|
|
.Em emacs-edit
|
|
for keys used when line editing at the command prompt;
|
|
.Em vi-choice
|
|
and
|
|
.Em emacs-choice
|
|
for keys used when choosing from lists (such as produced by the
|
|
.Ic window-choose
|
|
command) or in output mode; and
|
|
.Em vi-copy
|
|
and
|
|
.Em emacs-copy
|
|
used in copy and scroll modes.
|
|
The tables may be viewed with the
|
|
.Ic list-keys
|
|
command and keys modified or removed with
|
|
.Ic bind-key
|
|
and
|
|
.Ic unbind-key .
|
|
.Pp
|
|
The paste buffer key pastes the first line from the top paste buffer on the

.Sh OPTIONS
|
|
The appearance and behaviour of
|
|
.Nm
|
|
may be modified by changing the value of various options.
|
|
There are two types of option:
|
|
.Em session options
|
|
and
|
|
.Em window options .
|
|
.Pp
|
|
Each individual session may have a set of session options, and there is a
|
|
separate set of global session options.
|
|
Sessions which do not have a particular option configured inherit the value
|
|
from the global session options.
|
|
Session options are set or unset with the
|
|
.Ic set-option
|
|
command and may be listed with the
|
|
.Ic show-options
|
|
command.
|
|
The available session options are listed under the
|
|
.Ic set-option
|
|
command.
|
|
.Pp
|
|
Similarly, a set of window options is attached to each window, and there is
|
|
a set of global window options from which any unset options are inherited.
|
|
Window options are altered with the
|
|
.Ic set-window-option
|
|
command and can be listed with the
|
|
.Ic show-window-options
|
|
command.
|
|
All window options are documented with the
|
|
.Ic set-window-option
|
|
command.
|
|
.Pp
|
|
Commands which set options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Xo Ic set-option
|
|
.Op Fl agu
|
|
.Op Fl t Ar target-session
|
|
.Ar option Ar value
|
|
.Xc
|
|
.D1 (alias: Ic set )
|
|
Set a session option.
|
|
With
|
|
.Fl a ,
|
|
and if the option expects a string,
|
|
.Ar value
|
|
is appended to the existing setting.
|
|
If
|
|
.Fl g
|
|
is specified, the global session option is set.
|
|
The
|
|
.Fl u
|
|
flag unsets an option, so a session inherits the option from the global
|
|
options - it is not possible to unset a global option.
|
|
.Pp
|
|

.Sh STATUS LINE
|
|
.Nm
|
|
includes an optional status line which is displayed in the bottom line of each
|
|
terminal.
|
|
By default, the status line is enabled (it may be disabled with the
|
|
.Ic status
|
|
session option) and contains, from left-to-right: the name of the current
|
|
session in square brackets; the window list; the current window title in double
|
|
quotes; and the time and date.
|
|
.Pp
|
|
The status line is made of three parts: configurable left and right sections
|
|
(which may contain dynamic content such as the time or output from a shell
|
|
command, see the
|
|
.Ic status-left ,
|
|
.Ic status-left-length ,
|
|
.Ic status-right ,
|
|
and
|
|
.Ic status-right-length
|
|
options below), and a central window list.
|
|
The window list shows the index, name and (if any) flag of the windows
|
|
present in the current session in ascending numerical order.
|
|
The flag is one of the following symbols appended to the window name:
|
|
.Bl -column "Symbol" "Meaning" -offset indent
|
|
.It Sy "Symbol" Ta Sy "Meaning"
|
|
.It Li "*" Ta "Denotes the current window."
|
|
.It Li "-" Ta "Marks the last window (previously selected)."
|
|
.It Li "#" Ta "Window is monitored and activity has been detected."
|
|
.It Li "!" Ta "A bell has occurred in the window."
|
|
.It Li "+" Ta "Window is monitored for content and it has appeared."
|
|
.El
|
|
.Pp
|
|
The # symbol relates to the
|
|
.Ic monitor-activity
|
|
and + to the
|
|
.Ic monitor-content
|
|
window options.
|
|
The window name is printed in inverted colours if an alert (bell, activity or
|
|
content) is present.
|
|
.Pp
|
|
The colour and attributes of the status line may be configured, the entire status line using
|
|
the
|
|
.Ic status-attr ,
|
|
.Ic status-fg
|
|
and
|
|
.Ic status-bg
|
|
session options and individual windows using the
|
|
.Ic window-status-attr ,
|
|
.Ic window-status-fg
|
|
and
|
|
.Ic window-status-bg
|
|
window options.
|
|
.Pp
|
|
The status line is automatically refreshed at interval if it has changed, the interval may be
|
|
controlled with the
|
|
.Ic status-interval
|
|
session option.
|
|
.Pp
|
|

a single prompt is displayed, constructed from
|
|
.Ar template
|
|
if it is present, or
|
|
.Ql \&:
|
|
if not.
|
|
Before the command is executed, the first occurrence of the string
|
|
.Ql %%
|
|
and all occurrences of
|
|
.Ql %1
|
|
are replaced by the response to the first prompt, the second
|
