parser using yacc(1). This is a major change but is clearer and simpler
and allows some edge cases to be made more consistent, as well as
tidying up how aliases are handled. It will also allow some further
improvements later.
Entirely the same parser is now used for parsing the configuration file
and for string commands. This means that constructs previously only
available in .tmux.conf, such as %if, can now be used in string commands
(for example, those given to if-shell - not commands invoked from the
shell, they are still parsed by the shell itself).
The only syntax change I am aware of is that #{} outside quotes or a
comment is now considered a format and not a comment, so #{ is now a
syntax error (notably, if it is at the start of a line).
This also adds two new sections to the man page documenting the syntax
and outlining how parsing and command execution works.
Thanks to everyone who sent me test configs (they still all parse
without errors - but this doesn't mean they still work as intended!).
Thanks to Avi Halachmi for testing and man page improvements, also to
jmc@ for reviewing the man page changes.

.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 C
|
|
Start in control mode (see the
|
|
.Sx CONTROL MODE
|
|
section).
|
|
Given twice
|
|
.Xo ( Fl CC ) Xc
|
|
disables echo.
|
|
.It Fl c Ar shell-command
|
|
Execute
|
|
.Ar shell-command
|
|
using the default shell.
|
|
If necessary, the
|
|
.Nm
|
|
server will be started to retrieve the
|
|
.Ic default-shell
|
|
option.
|
|
This option is for compatibility with
|
|
.Xr sh 1
|
|
when
|
|
.Nm
|
|
is used as a login shell.
|
|
.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 .
|
|
.Pp
|
|
The configuration file is a set of
|
|
.Nm
|
|
commands which are executed in sequence when the server is first started.
|
|
.Nm
|
|
loads configuration files once when the server process has started.
|
|
The
|
|
.Ic source-file
|
|
command may be used to load a file later.
|
|
.Pp
|
|
.Nm
|
|
shows any error messages from commands in configuration files in the first
|
|
session created, and continues to process the rest of the configuration file.
|
|
.It Fl L Ar socket-name
|
|
.Nm
|
|
stores the server socket in a directory under
|
|
.Ev TMUX_TMPDIR
|
|
or
|
|
.Pa /tmp
|
|
if it is unset.
|
|
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 (note that this will fail if any parent
|
|
directories are missing).
|
|
.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 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
|
|
Write UTF-8 output to the terminal even if the first environment
|
|
variable of
|
|
.Ev LC_ALL ,
|
|
.Ev LC_CTYPE ,
|
|
or
|
|
.Ev LANG
|
|
that is set does not contain
|
|
.Qq UTF-8
|
|
or
|
|
.Qq UTF8 .
|
|
.It Fl v
|
|
Request verbose logging.
|
|
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.
|
|
If
|
|
.Fl v
|
|
is specified twice, an additional
|
|
.Pa tmux-out-PID.log
|
|
file is generated with a copy of everything
|
|
.Nm
|
|
writes to the terminal.
|
|
.Pp
|
|
The
|
|
.Dv SIGUSR2
|
|
signal may be sent to the
|
|
.Nm
|
|
server process to toggle logging between on (as if
|
|
.Fl v
|
|
was given) and off.
|
|
.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 DEFAULT KEY BINDINGS

|
.Nm
|
|

.Pp
|

Key bindings may be changed with the

.Ic unbind-key
|

|
|
.Sh COMMAND PARSING AND EXECUTION
|
|
.Nm
|
|
supports a large number of commands which can be used to control its
|
|
behaviour.
|
|
Each command is named and can accept zero or more flags and arguments.
|
|
They may be bound to a key with the
|
|
.Ic bind-key
|
|
command or run from the shell prompt, a shell script, a configuration file or
|
|
the command prompt.
|
|
For example, the same
|
|
.Ic set-option
|
|
command run from the shell prompt, from
|
|
.Pa ~/.tmux.conf
|
|
and bound to a key may look like:
|
|
.Bd -literal -offset indent
|
|
$ tmux set-option -g status-style bg=cyan
|
|
|
|
set-option -g status-style bg=cyan
|
|
|
|
bind-key C set-option -g status-style bg=cyan
|
|
.Ed
|
|
.Pp
|
|
Here, the command name is
|
|
.Ql set-option ,
|
|
.Ql Fl g
|
|
is a flag and
|
|
.Ql status-style
|
|
and
|
|
.Ql bg=cyan
|
|
are arguments.
|
|
.Pp
|
|
.Nm
|
|
distinguishes between command parsing and execution.
|
|
In order to execute a command,
|
|
.Nm
|
|
needs it to be split up into its name and arguments.
|
|
This is command parsing.
|
|
If a command is run from the shell, the shell parses it; from inside
|
|
.Nm
|
|
or from a configuration file,
|
|
.Nm
|
|
does.
|
|
Examples of when
|
|
.Nm
|
|
parses commands are:
|
|
.Bl -dash -offset indent
|
|
.It
|
|
in a configuration file;
|
|
.It
|
|
typed at the command prompt (see
|
|
.Ic command-prompt ) ;
|
|
.It
|
|
given to
|
|
.Ic bind-key ;
|
|
.It
|
|
passed as arguments to
|
|
.Ic if-shell
|
|
or
|
|
.Ic confirm-before .
|
|
.El
|
|
.Pp
|
|
To execute commands, each client has a
|
|
.Ql command queue .
|
|
A global command queue not attached to any client is used on startup
|
|
for configuration files like
|
|
.Pa ~/.tmux.conf .
|
|
Parsed commands added to the queue are executed in order.
|
|
Some commands, like
|
|
.Ic if-shell
|
|
and
|
|
.Ic confirm-before ,
|
|
parse their argument to create a new command which is inserted immediately
|
|
after themselves.
|
|
This means that arguments can be parsed twice or more - once when the parent command (such as
|
|
.Ic if-shell )
|
|
is parsed and again when it parses and executes its command.
|
|
Commands like
|
|
.Ic if-shell ,
|
|
.Ic run-shell
|
|
and
|
|
.Ic display-panes
|
|
stop execution of subsequent commands on the queue until something happens -
|
|
.Ic if-shell
|
|
and
|
|
.Ic run-shell
|
|
until a shell command finishes and
|
|
.Ic display-panes
|
|
until a key is pressed.
|
|
For example, the following commands:
|
|
.Bd -literal -offset indent
|
|
new-session; new-window
|
|
if-shell "true" "split-window"
|
|
kill-session
|
|
.Ed
|
|
.Pp
|
|
Will execute
|
|
.Ic new-session ,
|
|
.Ic new-window ,
|
|
.Ic if-shell ,
|
|
the shell command
|
|
.Xr true 1 ,
|
|
.Ic new-window
|
|
and
|
|
.Ic kill-session
|
|
in that order.
|
|
.Pp
|
|
The
|
|
.Sx COMMANDS
|
|
section lists the
|
|
.Nm
|
|
commands and their arguments.
|
|
.Sh PARSING SYNTAX
|
|
This section describes the syntax of commands parsed by
|
|
.Nm ,
|
|
for example in a configuration file or at the command prompt.
|
|
Note the when commands are entered into the shell, they are parsed by the shell
|
|
- see for example
|
|
.Xr ksh 1
|
|
or
|
|
.Xr csh 1 .
|
|
.Pp
|
|
Each command is terminated by a newline or a semicolon (;).
|
|
Commands separated by semicolons together form a
|
|
.Ql command sequence
|
|
- if a command in the sequence encounters an error, no subsequent commands are
|
|
executed.
|
|
.Pp
|
|
Comments are marked by the unquoted # character - any remaining text after a
|
|
comment is ignored until the end of the line.
|
|
.Pp
|
|
If the last character of a line is \e, the line is joined with the following
|
|
line (the \e and the newline are completely removed).
|
|
This is called line continuation and applies both inside and outside quoted
|
|
strings and in comments.
|
|
.Pp
|
|
Command arguments may be specified as strings surrounded by either single (')
|
|
or double quotes (").
|
|
.\" "
|
|
This is required when the argument contains any special character.
|
|
Strings cannot span multiple lines except with line continuation.
|
|
.Pp
|
|
Outside of quotes and inside double quotes, these replacements are performed:
|
|
.Bl -dash -offset indent
|
|
.It
|
|
Environment variables preceded by $ are replaced with their value from the
|
|
global environment (see the
|
|
.Sx GLOBAL AND SESSION ENVIRONMENT
|
|
section).
|
|
.It
|
|
A leading ~ or ~user is expanded to the home directory of the current or
|
|
specified user.
|
|
.It
|
|
\euXXXX or \euXXXXXXXX is replaced by the Unicode codepoint corresponding to
|
|
the given four or eight digit hexadecimal number.
|
|
.It
|
|
When preceded (escaped) by a \e, the following characters are replaced: \ee by
|
|
the escape character; \er by a carriage return; \en by a newline; and \et by a
|
|
tab.
|
|
.Pp
|
|
Any other characters preceded by \e are replaced by themselves (that is, the \e
|
|
is removed) and are not treated as having any special meaning - so for example
|
|
\e; will not mark a command sequence and \e$ will not expand an environment
|
|
variable.
|
|
.El
|
|
.Pp
|
|
Environment variables may be set by using the syntax
|
|
.Ql name=value ,
|
|
for example
|
|
.Ql HOME=/home/user .
|
|
Variables set during parsing are added to the global environment.
|
|
.Pp
|
|
Commands may be parsed conditionally by surrounding them with
|
|
.Ql %if ,
|
|
.Ql %elif ,
|
|
.Ql %else
|
|
and
|
|
.Ql %endif .
|
|
The argument to
|
|
.Ql %if
|
|
and
|
|
.Ql %elif
|
|
is expanded as a format (see
|
|
.Sx FORMATS )
|
|
and if it evaluates to false (zero or empty), subsequent text is ignored until
|
|
the closing
|
|
.Ql %elif ,
|
|
.Ql %else
|
|
or
|
|
.Ql %endif .
|
|
For example:
|
|
.Bd -literal -offset indent
|
|
%if #{==:#{host},myhost}
|
|
set -g status-style bg=red
|
|
%elif #{==:#{host},myotherhost}
|
|
set -g status-style bg=green
|
|
%else
|
|
set -g status-style bg=blue
|
|
%endif
|
|
.Ed
|
|
.Pp
|
|
Will change the status line to red if running on
|
|
.Ql myhost ,
|
|
green if running on
|
|

.Sh COMMANDS
|
|
This section describes the commands supported by
|
|
.Nm .
|
|
Most commands accept the optional
|
|
.Fl t
|
|
(and sometimes
|
|
.Fl s )
|
|
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.
|
|
.Pp
|
|
.Ar target-client
|
|
should be the name of the client,
|
|
typically 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,
|
|
.Nm
|
|
attempts to work out the client currently in use; if that fails, an error is
|
|
reported.
|
|
Clients may be listed with the
|
|
.Ic list-clients
|
|
command.
|
|
.Pp
|
|
.Ar target-session
|
|
is tried as, in order:
|
|
.Bl -enum -offset Ds
|
|
.It
|
|
A session ID prefixed with a $.
|
|
.It
|
|
An exact name of a session (as listed by the
|
|
.Ic list-sessions
|
|
command).
|
|
.It
|
|
The start of a session name, for example
|
|
.Ql mysess
|
|
would match a session named
|
|
.Ql mysession .
|
|
.It
|
|
An
|
|
.Xr fnmatch 3
|
|
pattern which is matched against the session name.
|
|
.El
|
|
.Pp
|
|
If the session name is prefixed with an
|
|
.Ql = ,
|
|
only an exact match is accepted (so
|
|
.Ql =mysess
|
|
will only match exactly
|
|
.Ql mysess ,
|
|
not
|
|
.Ql mysession ) .
|
|
.Pp
|
|
If a single session 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 used is chosen.
|
|
.Pp
|
|
.Ar target-window
|
|
(or
|
|
.Ar src-window
|
|
or
|
|
.Ar dst-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:
|
|
.Bl -enum -offset Ds
|
|
.It
|
|
A special token, listed below.
|
|
.It
|
|
A window index, for example
|
|
.Ql mysession:1
|
|
is window 1 in session
|
|
.Ql mysession .
|
|
.It
|
|
A window ID, such as @1.
|
|
.It
|
|
An exact window name, such as
|
|
.Ql mysession:mywindow .
|
|
.It
|
|
The start of a window name, such as
|
|
.Ql mysession:mywin .
|
|
.It
|
|
As an
|
|
.Xr fnmatch 3
|
|
pattern matched against the window name.
|
|
.El
|
|
.Pp
|
|
Like sessions, a
|
|
.Ql =
|
|
prefix will do an exact match only.
|
|
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.
|
|
.Pp
|
|
The following special tokens are available to indicate particular windows.
|
|
Each has a single-character alternative form.
|
|
.Bl -column "XXXXXXXXXX" "X"
|
|
.It Sy "Token" Ta Sy "" Ta Sy "Meaning"
|
|
.It Li "{start}" Ta "^" Ta "The lowest-numbered window"
|
|
.It Li "{end}" Ta "$" Ta "The highest-numbered window"
|

.It Li "{last}" Ta "!" Ta "The last (previously current) window"
|
|
.It Li "{next}" Ta "+" Ta "The next window by number"
|
|
.It Li "{previous}" Ta "-" Ta "The previous window by number"
|
|
.El
|
|
.Pp
|
|
.Ar target-pane
|
|
(or
|
|
.Ar src-pane
|
|
or
|
|
.Ar dst-pane )
|
|
may be a pane ID or takes a similar form to
|
|
.Ar target-window
|
|
but with the optional addition of a period followed by a pane index or pane ID,
|
|
for example:
|
|
.Ql mysession:mywindow.1 .
|
|
If the pane index is omitted, the currently active pane in the specified
|
|
window is used.
|
|
The following special tokens are available for the pane index:
|
|
.Bl -column "XXXXXXXXXXXXXX" "X"
|
|
.It Sy "Token" Ta Sy "" Ta Sy "Meaning"
|
|
.It Li "{last}" Ta "!" Ta "The last (previously active) pane"
|
|
.It Li "{next}" Ta "+" Ta "The next pane by number"
|
|
.It Li "{previous}" Ta "-" Ta "The previous pane by number"
|
|
.It Li "{top}" Ta "" Ta "The top pane"
|

.It Li "{up-of}" Ta "" Ta "The pane above the active pane"
|
|
.It Li "{down-of}" Ta "" Ta "The pane below the active pane"
|
|
.It Li "{left-of}" Ta "" Ta "The pane to the left of the active pane"
|
|
.It Li "{right-of}" Ta "" Ta "The pane to the right of the active pane"
|
|
.El
|
|
.Pp
|
|
The tokens
|
|
.Ql +
|
|
and
|
|
.Ql -
|
|
may be followed by an offset, for example:
|
|
.Bd -literal -offset indent
|
|
select-window -t:+2
|
|
.Ed
|
|
.Pp
|
|
In addition,
|
|
.Em target-session ,
|
|
.Em target-window
|
|
or
|
|
.Em target-pane
|
|
may consist entirely of the token
|
|
.Ql {mouse}
|
|
(alternative form
|
|
.Ql = )
|
|
to specify the most recent mouse event
|
|
(see the
|
|
.Sx MOUSE SUPPORT
|
|
section)
|
|
or
|
|
.Ql {marked}
|
|
(alternative form
|
|
.Ql ~ )
|
|
to specify the marked pane (see
|
|
.Ic select-pane
|
|
.Fl m ) .
|
|
.Pp
|
|
Sessions, window and panes are each numbered with a unique ID; session IDs are
|
|
prefixed with a
|
|
.Ql $ ,
|
|
windows with a
|
|
.Ql @ ,
|
|
and panes with a
|
|
.Ql % .
|
|
These are unique and are unchanged for the life of the session, window or pane
|
|
in the
|
|
.Nm
|
|
server.
|
|
The pane ID is passed to the child process of the pane in the
|
|
.Ev TMUX_PANE
|
|
environment variable.
|
|
IDs may be displayed using the
|
|
.Ql session_id ,
|
|
.Ql window_id ,
|
|
or
|
|
.Ql pane_id
|
|
formats (see the
|
|
.Sx FORMATS
|
|
section) and the
|
|
.Ic display-message ,
|
|
.Ic list-sessions ,
|
|
.Ic list-windows
|
|
or
|
|
.Ic list-panes
|
|
commands.
|
|
.Pp
|
|
.Ar shell-command
|
|
arguments are
|
|
.Xr sh 1
|
|
commands.
|
|
This may be a single argument passed to the shell, for example:
|
|
.Bd -literal -offset indent
|
|
new-window 'vi /etc/passwd'
|
|
.Ed
|
|
.Pp
|
|
Will run:
|
|
.Bd -literal -offset indent
|
|
/bin/sh -c 'vi /etc/passwd'
|
|
.Ed
|
|
.Pp
|
|
Additionally, the
|
|
.Ic new-window ,
|
|
.Ic new-session ,
|
|
.Ic split-window ,
|
|
.Ic respawn-window
|
|
and
|
|
.Ic respawn-pane
|
|
commands allow
|
|
.Ar shell-command
|
|
to be given as multiple arguments and executed directly (without
|
|
.Ql sh -c ) .
|
|
This can avoid issues with shell quoting.
|
|
For example:
|
|
.Bd -literal -offset indent
|
|
$ tmux new-window vi /etc/passwd
|
|
.Ed
|
|
.Pp
|
|
Will run
|
|
.Xr vi 1
|
|
directly without invoking the shell.
|
|
.Pp
|
|
.Ar command
|
|
.Op Ar arguments
|
|
refers to a
|
|
.Nm
|
|
command, passed with the command and arguments separately, for example:
|
|
.Bd -literal -offset indent
|
|
bind-key F1 set-option status off
|
|
.Ed
|
|
.Pp
|
|
Or if using
|
|
.Xr sh 1 :
|
|
.Bd -literal -offset indent
|
|
$ tmux bind-key F1 set-option status off
|
|
.Ed
|

.Sh CLIENTS AND SESSIONS
|
|
The
|
|
.Nm
|
|
server manages clients, sessions, windows and panes.
|
|
Clients are attached to sessions to interact with them, either
|
|
when they are created with the
|
|
.Ic new-session
|
|
command, or later with the
|
|
.Ic attach-session
|
|
command.
|
|
Each session has one or more windows
|
|
.Em linked
|
|
into it.
|
|
Windows may be linked to multiple sessions and are made up of one or
|
|
more panes,
|
|
each of which contains a pseudo terminal.
|
|
Commands for creating, linking and otherwise manipulating windows
|
|
are covered
|
|
in the
|
|
.Sx WINDOWS AND PANES
|
|
section.
|
|
.Pp
|
|
The following commands are available to manage clients and sessions:
|
|
.Bl -tag -width Ds
|

|
|
If run from outside
|
|
.Nm ,
|
|
create a new client in the current terminal and attach it to
|
|
.Ar target-session .
|
|
If used from inside, switch the current client.
|
|
If
|
|
.Fl d
|
|
is specified, any other clients attached to the session are detached.
|
|
.Fl r
|
|
signifies the client is read-only (only keys bound to the
|
|
.Ic detach-client
|
|
or
|
|
.Ic switch-client
|
|
commands have any effect)
|
|
.Pp
|
|
If no server is started,
|
|
.Ic attach-session
|
|
will attempt to start it; this will fail unless sessions are created in the
|
|
configuration file.
|
|
.Pp
|
|
The
|
|
.Ar target-session
|
|
rules for
|
|
.Ic attach-session
|
|
are slightly adjusted: if
|
|
.Nm
|
|
needs to select the most recently used session, it will prefer the most
|
|
recently used
|
|
.Em unattached
|
|
session.
|
|
.Pp
|
|
.Fl c
|
|
will set the session working directory (used for new windows) to

|
|
or all clients currently attached to the session specified by
|
|
.Fl s .
|
|
The
|

option kills all but the client given with
|
|
.Fl t .
|
|
If
|
|
.Fl P
|

The new session is attached to the current terminal unless
|
|
.Fl d
|
|
is given.
|
|
.Ar window-name
|
|
and
|
|
.Ar shell-command
|
|
are the name of and shell command to execute in the initial window.
|
|
With

|
|
Sessions in the same group share the same set of windows - new windows are
|
|
linked to all sessions in the group and any windows closed removed from all
|
|
sessions.
|
|
The current and previous window and any session options remain independent and
|
|
any session in a group may be killed without affecting the others.
|
|
The

.It
|
|
the name of an existing group, in which case the new session is added to that
|
|
group;
|
|
.It
|
|
the name of an existing session - the new session is added to the same group
|

as that session, creating a new group if necessary;
|
|
.It
|
|
the name for a new group containing only the new session.

.Sh WINDOWS AND PANES
|
|
A
|
|
.Nm
|
|
window may be in one of two modes.
|
|
The default permits direct access to the terminal attached to the window.
|
|
The other is copy mode, which 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.
|
|
It is also entered when a command that produces output, such as
|
|
.Ic list-keys ,
|
|
is executed from a key binding.
|
|
.Pp
|
|
Commands are sent to copy mode using the
|
|
.Fl X
|
|
flag to the
|
|
.Ic send-keys
|
|
command.
|
|
When a key is pressed, copy mode automatically uses one of two key tables,
|
|
depending on the
|
|
.Ic mode-keys
|
|
option:
|
|
.Ic copy-mode
|
|
for emacs, or
|
|
.Ic copy-mode-vi
|
|
for vi.
|
|
Key tables may be viewed with the
|
|
.Ic list-keys
|
|
command.
|
|

|
|
Copy commands may take an optional buffer prefix argument which is used
|
|
to generate the buffer name (the default is
|
|
.Ql buffer
|
|
so buffers are named
|
|
.Ql buffer0 ,
|
|
.Ql buffer1
|
|
and so on).
|
|
Pipe commands take a command argument which is the command to which the
|
|
copied text is piped.
|
|
The
|
|
.Ql -and-cancel
|
|
variants of some commands exit copy mode after they have completed (for copy
|
|
commands) or when the cursor reaches the bottom (for scrolling commands).
|
|
.Ql -no-clear
|
|
variants do not clear the selection.
|
|
.Pp
|
|
The next and previous word keys use space and the
|
|
.Ql - ,
|
|
.Ql _
|
|
and
|
|
.Ql @
|
|
characters as word delimiters by default, but this can be adjusted by
|
|
setting the
|
|
.Em word-separators
|
|
session option.
|
|
Next word moves to the start of the next word, next word end to the end of the
|
|
next word and previous word to the start of the previous word.
|
|
The three next and previous space keys work similarly but use a space alone as
|
|
the word separator.
|
|
.Pp
|
|
The jump commands enable quick movement within a line.
|
|
For instance, typing
|
|
.Ql f
|
|
followed by
|
|
.Ql /
|
|
will move the cursor to the next
|
|
.Ql /
|
|
character on the current line.
|
|
A
|
|
.Ql \&;
|
|
will then jump to the next occurrence.
|
|
.Pp
|
|
Commands in copy mode may be prefaced by an optional repeat count.
|
|
With vi key bindings, a prefix is entered using the number keys; with
|
|
emacs, the Alt (meta) key and a number begins prefix entry.
|
|
.Pp
|
|
The synopsis for the
|
|
.Ic copy-mode
|
|
command is:
|
|
.Bl -tag -width Ds
|
|
.It Xo Ic copy-mode
|
|
.Op Fl Meu
|
|
.Op Fl t Ar target-pane
|
|
.Xc
|
|
Enter copy mode.
|
|
The
|
|
.Fl u
|
|
option scrolls one page up.
|
|
.Fl M
|
|
begins a mouse drag (only valid if bound to a mouse key binding, see
|
|
.Sx MOUSE SUPPORT ) .
|
|
.Fl e
|
|
specifies that scrolling to the bottom of the history (to the visible screen)
|
|
should exit copy mode.
|
|
While in copy mode, pressing a key other than those used for scrolling will
|
|
disable this behaviour.
|
|
This is intended to allow fast scrolling through a pane's history, for
|
|
example with:
|
|
.Bd -literal -offset indent
|
|
bind PageUp copy-mode -eu
|
|
.Ed
|
|
.El
|
|
.Pp
|
|
Each window displayed by
|
|
.Nm
|
|
may be split into one or more
|
|
.Em panes ;
|
|
each pane takes up a certain area of the display and is a separate terminal.
|
|
A window may be split into panes using the
|
|
.Ic split-window
|
|
command.
|
|
Windows may be split horizontally (with the
|
|
.Fl h
|
|
flag) or vertically.
|
|
Panes may be resized with the
|
|
.Ic resize-pane
|
|
command (bound to
|
|
.Ql C-Up ,
|
|
.Ql C-Down
|
|
.Ql C-Left
|
|
and
|
|
.Ql C-Right
|
|
by default), the current pane may be changed with the
|
|
.Ic select-pane
|
|
command and the
|
|
.Ic rotate-window
|
|
and
|
|
.Ic swap-pane
|
|
commands may be used to swap panes without changing their position.
|
|
Panes are numbered beginning from zero in the order they are created.
|
|
.Pp
|
|
A number of preset
|
|
.Em layouts
|
|
are available.
|
|
These may be selected with the
|
|
.Ic select-layout
|
|
command or cycled with
|
|
.Ic next-layout
|
|
(bound to
|
|
.Ql Space
|
|
by default); once a layout is chosen, panes within it may be moved and resized
|
|
as normal.
|
|
.Pp
|
|
The following layouts are supported:
|
|
.Bl -tag -width Ds
|
|
.It Ic even-horizontal
|
|
Panes are spread out evenly from left to right across the window.
|
|
.It Ic even-vertical
|
|
Panes are spread evenly from top to bottom.
|
|
.It Ic main-horizontal
|
|
A large (main) pane is shown at the top of the window and the remaining panes
|
|
are spread from left to right in the leftover space at the bottom.
|
|
Use the
|
|
.Em main-pane-height
|
|
window option to specify the height of the top pane.
|
|
.It Ic main-vertical
|
|
Similar to
|
|
.Ic main-horizontal
|
|
but the large pane is placed on the left and the others spread from top to
|
|
bottom along the right.
|
|
See the
|
|
.Em main-pane-width
|
|
window option.
|
|
.It Ic tiled
|
|
Panes are spread out as evenly as possible over the window in both rows and
|
|
columns.
|
|
.El
|
|
.Pp
|
|
In addition,
|
|
.Ic select-layout
|
|
may be used to apply a previously used layout - the
|
|
.Ic list-windows
|
|
command displays the layout of each window in a form suitable for use with
|
|
.Ic select-layout .
|
|
For example:
|
|
.Bd -literal -offset indent
|
|
$ tmux list-windows
|
|
0: ksh [159x48]
|
|
layout: bb62,159x48,0,0{79x48,0,0,79x48,80,0}
|
|
$ tmux select-layout bb62,159x48,0,0{79x48,0,0,79x48,80,0}
|
|
.Ed
|
|
.Pp
|
|
.Nm
|
|
automatically adjusts the size of the layout for the current window size.
|
|
Note that a layout cannot be applied to a window with more panes than that
|
|
from which the layout was originally defined.
|

|
.Ql activity .
|
|
.Fl f
|
|
specifies an initial filter: the filter is a format - if it evaluates to zero,
|
|
the item in the list is not shown, otherwise it is shown.
|
|
If a filter would lead to an empty list, it is ignored.
|
|
.Fl F
|
|
specifies the format for each item in the list.
|
|
.Fl N
|

options are used,
|
|
.Ic select-pane

select-pane -t:.1 -P 'bg=red'
|
|
.Ed
|

|
|
Create a new pane by splitting
|
|
.Ar target-pane :
|
|
.Fl h
|
|
does a horizontal split and
|
|
.Fl v
|
|
a vertical split; if neither is specified,
|
|
.Fl v
|
|
is assumed.
|
|
The
|
|
.Fl l
|
|
and
|
|
.Fl p
|
|
options specify the size of the new pane in lines (for vertical split) or in
|
|
cells (for horizontal split), or as a percentage, respectively.
|
|
The
|
|
.Fl b
|
|
option causes the new pane to be created to the left of or above
|
|
.Ar target-pane .
|
|
The
|
|
.Fl f
|
|
option creates a new pane spanning the full window height (with
|
|
.Fl h )
|
|
or full window width (with
|
|
.Fl v ) ,
|
|
instead of splitting the active pane.
|
|
.Pp
|
|
An empty
|
|
.Ar shell-command
|
|
('') will create a pane with no command running in it.
|
|
Output can be sent to such a pane with the
|
|
.Ic display-message
|
|
command.
|
|
The
|
|
.Fl I
|
|
flag (if
|
|
.Ar shell-command
|
|
is not specified or empty)
|
|
will create an empty pane and forward any output from stdin to it.

.Bd -literal -offset indent
|
|
$ make 2>&1|tmux splitw -dI &

.Sh KEY BINDINGS
|
|
.Nm
|
|
allows a command to be bound to most keys, with or without a prefix key.
|
|
When specifying keys, most represent themselves (for example
|
|
.Ql A
|
|
to
|
|
.Ql Z ) .
|
|
Ctrl keys may be prefixed with
|
|
.Ql C-
|
|
or
|
|
.Ql ^ ,
|
|
and Alt (meta) with
|
|
.Ql M- .
|
|
In addition, the following special key names are accepted:
|
|
.Em Up ,
|
|
.Em Down ,
|
|
.Em Left ,
|
|
.Em Right ,
|
|
.Em BSpace ,
|
|
.Em BTab ,
|
|
.Em DC
|
|
(Delete),
|
|
.Em End ,
|
|
.Em Enter ,
|
|
.Em Escape ,
|
|
.Em F1
|
|
to
|
|
.Em F12 ,
|
|
.Em Home ,
|
|
.Em IC
|
|
(Insert),
|
|
.Em NPage/PageDown/PgDn ,
|
|
.Em PPage/PageUp/PgUp ,
|
|
.Em Space ,
|
|
and
|
|
.Em Tab .
|
|
Note that to bind the
|
|
.Ql \&"
|
|
or
|
|
.Ql '
|
|
keys, quotation marks are necessary, for example:
|
|
.Bd -literal -offset indent
|
|
bind-key '"' split-window
|
|
bind-key "'" new-window
|
|
.Ed
|
|
.Pp
|
|
Commands related to key bindings are as follows:

.Op Fl nr
|
|
.Op Fl T Ar key-table
|
|

.Xc
|
|
.D1 (alias: Ic bind )
|
|
Bind key
|
|
.Ar key
|
|
to
|
|
.Ar command .
|
|
Keys are bound in a key table.
|
|
By default (without -T), the key is bound in
|
|
the
|
|
.Em prefix
|
|
key table.
|
|
This table is used for keys pressed after the prefix key (for example,
|
|
by default
|
|
.Ql c
|
|
is bound to
|
|
.Ic new-window
|
|
in the
|
|
.Em prefix
|
|
table, so
|
|
.Ql C-b c
|
|
creates a new window).
|
|
The
|
|
.Em root
|
|
table is used for keys pressed without the prefix key: binding
|
|
.Ql c
|
|
to
|
|
.Ic new-window
|
|
in the
|
|
.Em root
|
|
table (not recommended) means a plain
|
|
.Ql c
|
|
will create a new window.
|
|
.Fl n
|
|
is an alias
|
|
for
|
|
.Fl T Ar root .
|
|
Keys may also be bound in custom key tables and the
|
|
.Ic switch-client
|
|
.Fl T
|
|
command used to switch to them from a key binding.
|
|
The
|
|
.Fl r
|
|
flag indicates this key may repeat, see the
|
|
.Ic repeat-time
|
|
option.

.D1 (alias: Ic send )
|

Each argument
|
|
.Ar key
|
|
is the name of the key (such as
|
|
.Ql C-a
|
|
or
|
|
.Ql NPage )
|
|
to send; if the string is not recognised as a key, it is sent as a series of
|
|
characters.
|
|
The
|
|
.Fl l

|
flag disables key name lookup and sends the keys literally.
|
|
All arguments are sent sequentially from first to last.

.El
|
|
.Sh OPTIONS
|
|
The appearance and behaviour of
|
|
.Nm
|
|
may be modified by changing the value of various options.
|
|
There are three types of option:
|
|
.Em server options ,
|
|
.Em session options
|
|
and
|
|
.Em window options .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
server has a set of global options which do not apply to any particular
|
|
window or session.
|
|
These are altered with the
|
|
.Ic set-option
|
|
.Fl s
|
|
command, or displayed with the
|
|
.Ic show-options
|
|
.Fl s
|
|
command.
|
|
.Pp
|
|
In addition, 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 server and 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
|
|
.Nm
|
|
also supports user options which are prefixed with a
|
|
.Ql \&@ .
|
|
User options may have any name, so long as they are prefixed with
|
|
.Ql \&@ ,
|
|
and be set to any string.
|
|
For example:
|
|
.Bd -literal -offset indent
|
|
$ tmux setw -q @foo "abc123"
|
|
$ tmux showw -v @foo
|
|
abc123
|
|
.Ed
|
|
.Pp
|
|
Commands which set options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Xo Ic set-option
|
|
.Op Fl aFgoqsuw
|
|
.Op Fl t Ar target-session | Ar target-window
|
|
.Ar option Ar value
|
|
.Xc
|
|
.D1 (alias: Ic set )
|
|
Set a window option with
|
|
.Fl w
|
|
(equivalent to the
|
|
.Ic set-window-option
|
|
command),
|
|
a server option with
|
|
.Fl s ,
|
|
otherwise a session option.
|
|
If the option is not a user option,
|
|
.Fl w
|
|
and
|
|
.Fl s
|
|
are unnecessary -
|
|
.Nm
|
|
will infer the type from the option name.
|
|
If
|
|
.Fl g
|
|
is given, the global session or window option is set.
|
|
.Pp
|
|
.Fl F
|
|
expands formats in the option value.
|
|
The
|
|
.Fl u
|
|
flag unsets an option, so a session inherits the option from the global
|
|
options (or with
|
|
.Fl g ,
|
|
restores a global option to the default).
|
|
.Pp
|
|
The
|
|
.Fl o
|
|
flag prevents setting an option that is already set and the
|
|
.Fl q
|
|
flag suppresses errors about unknown or ambiguous options.
|
|
.Pp
|
|
With
|
|
.Fl a ,
|
|
and if the option expects a string or a style,
|
|
.Ar value
|
|
is appended to the existing setting.
|
|
For example:
|
|
.Bd -literal -offset indent
|
|
set -g status-left "foo"
|
|
set -ag status-left "bar"
|
|
.Ed
|
|
.Pp
|
|
Will result in
|
|
.Ql foobar .
|
|
And:
|
|
.Bd -literal -offset indent
|
|
set -g status-style "bg=red"
|
|
set -ag status-style "fg=blue"
|
|
.Ed
|
|
.Pp
|
|
Will result in a red background
|
|
.Em and
|
|
blue foreground.
|
|
Without
|
|
.Fl a ,
|
|
the result would be the default background and a blue foreground.
|
|
.Pp
|
|
Available window options are listed under
|
|
.Ic set-window-option .
|
|
.Pp
|
|
.Ar value
|
|
depends on the option and may be a number, a string, or a flag (on, off, or
|
|
omitted to toggle).
|
|
.Pp
|
|
Available server options are:
|
|
.Bl -tag -width Ds
|
|
.It Ic buffer-limit Ar number
|
|
Set the number of buffers; as new buffers are added to the top of the stack,
|
|
old ones are removed from the bottom if necessary to maintain this maximum
|
|
length.
|
|
.It Xo Ic command-alias[]
|
|
.Ar name=value
|
|
.Xc
|
|
This is an array of custom aliases for commands.
|
|
If an unknown command matches
|
|
.Ar name ,
|
|
it is replaced with
|
|
.Ar value .
|
|
For example, after:
|
|
.Pp
|
|
.Dl set -s command-alias[100] zoom='resize-pane -Z'
|
|
.Pp
|
|
Using:
|
|
.Pp
|
|
.Dl zoom -t:.1
|
|
.Pp
|
|
Is equivalent to:
|
|
.Pp
|
|
.Dl resize-pane -Z -t:.1
|
|
.Pp
|
|
Note that aliases are expanded when a command is parsed rather than when it is
|
|
executed, so binding an alias with
|
|
.Ic bind-key
|
|
will bind the expanded form.
|
|
.It Ic default-terminal Ar terminal
|
|
Set the default terminal for new windows created in this session - the
|
|
default value of the
|
|
.Ev TERM
|
|
environment variable.
|
|
For
|
|
.Nm
|
|
to work correctly, this
|
|
.Em must
|
|
be set to
|
|
.Ql screen ,
|
|
.Ql tmux
|
|
or a derivative of them.
|
|
.It Ic escape-time Ar time
|
|
Set the time in milliseconds for which
|
|
.Nm
|
|
waits after an escape is input to determine if it is part of a function or meta
|
|
key sequences.
|
|
The default is 500 milliseconds.
|
|
.It Xo Ic exit-empty
|
|
.Op Ic on | off
|
|
.Xc
|
|
If enabled (the default), the server will exit when there are no active
|
|
sessions.
|
|
.It Xo Ic exit-unattached
|
|
.Op Ic on | off
|
|
.Xc
|
|
If enabled, the server will exit when there are no attached clients.
|
|
.It Xo Ic focus-events
|
|
.Op Ic on | off
|
|
.Xc
|
|
When enabled, focus events are requested from the terminal if supported and
|
|
passed through to applications running in
|
|
.Nm .
|
|
Attached clients should be detached and attached again after changing this
|
|
option.
|
|
.It Ic history-file Ar path
|
|
If not empty, a file to which
|
|
.Nm
|
|
will write command prompt history on exit and load it from on start.
|
|
.It Ic message-limit Ar number
|
|
Set the number of error or information messages to save in the message log for

|
each client.
|
|
The default is 100.
|
|
.It Xo Ic set-clipboard
|
|

.Sh HOOKS
|
|
.Nm
|
|
allows commands to run on various triggers, called
|
|
.Em hooks .
|
|
Most
|
|
.Nm
|
|
commands have an
|
|
.Em after
|
|
hook and there are a number of hooks not associated with commands.
|
|
.Pp
|
|
Hooks are stored as array options, members of the array are executed in
|
|
order when the hook is triggered.
|
|
Hooks may be configured with the
|
|
.Ic set-hook
|
|
or
|
|
.Ic set-option
|
|
commands and displayed with
|
|
.Ic show-hooks
|
|
or
|
|
.Ic show-options
|
|
.Fl H .
|
|
The following two commands are equivalent:
|
|
.Bd -literal -offset indent.
|
|
set-hook -g pane-mode-changed[42] 'set -g status-left-style bg=red'
|
|
set-option -g pane-mode-changed[42] 'set -g status-left-style bg=red'
|
|
.Ed
|
|
.Pp
|
|
Setting a hook without specifying an array index clears the hook and sets the
|
|
first member of the array.
|
|
.Pp
|
|
A command's after
|
|
hook is run after it completes, except when the command is run as part of a hook
|
|
itself.
|
|
They are named with an
|
|
.Ql after-
|
|
prefix.
|
|
For example, the following command adds a hook to select the even-vertical
|
|
layout after every
|
|
.Ic split-window :
|
|
.Bd -literal -offset indent
|
|
set-hook -g after-split-window "selectl even-vertical"
|
|
.Ed
|
|
.Pp
|
|
All the notifications listed in the
|
|
.Sx CONTROL MODE
|
|
section are hooks (without any arguments), except
|
|
.Ic %exit .
|
|
The following additional hooks are available:
|
|
.Bl -tag -width "XXXXXXXXXXXXXXXXXXXXXX"
|
|
.It alert-activity
|
|
Run when a window has activity.
|
|
See
|

.Sh MOUSE SUPPORT
|
|
If the
|
|
.Ic mouse
|
|
option is on (the default is off),
|
|
.Nm
|
|
allows mouse events to be bound as keys.
|
|
The name of each key is made up of a mouse event (such as
|
|
.Ql MouseUp1 )
|
|
and a location suffix, one of the following:
|
|
.Bl -column "XXXXXXXXXXXXX" -offset indent
|
|
.It Li "Pane" Ta "the contents of a pane"
|
|
.It Li "Border" Ta "a pane border"
|
|
.It Li "Status" Ta "the status line window list"
|
|
.It Li "StatusLeft" Ta "the left part of the status line"
|
|
.It Li "StatusRight" Ta "the right part of the status line"
|
|
.It Li "StatusDefault" Ta "any other part of the status line"
|
|
.El
|
|
.Pp
|
|
The following mouse events are available:
|
|
.Bl -column "MouseDown1" "MouseDrag1" "WheelDown" -offset indent
|
|
.It Li "WheelUp" Ta "WheelDown" Ta ""
|
|
.It Li "MouseDown1" Ta "MouseUp1" Ta "MouseDrag1" Ta "MouseDragEnd1"
|
|
.It Li "MouseDown2" Ta "MouseUp2" Ta "MouseDrag2" Ta "MouseDragEnd2"
|
|
.It Li "MouseDown3" Ta "MouseUp3" Ta "MouseDrag3" Ta "MouseDragEnd3"
|
|
.It Li "DoubleClick1" Ta "DoubleClick2" Ta "DoubleClick3"
|
|
.It Li "TripleClick1" Ta "TripleClick2" Ta "TripleClick3"
|
|
.El
|
|
.Pp
|
|
Each should be suffixed with a location, for example
|
|
.Ql MouseDown1Status .
|
|
.Pp
|
|
The special token
|
|
.Ql {mouse}
|
|
or
|
|
.Ql =
|
|
may be used as
|
|
.Ar target-window
|
|
or
|
|
.Ar target-pane
|
|
in commands bound to mouse key bindings.
|
|
It resolves to the window or pane over which the mouse event took place
|
|
(for example, the window in the status line over which button 1 was released for a
|
|
.Ql MouseUp1Status
|
|
binding, or the pane over which the wheel was scrolled for a
|
|
.Ql WheelDownPane
|
|
binding).
|
|
.Pp
|
|
The
|
|
.Ic send-keys
|
|
.Fl M
|
|
flag may be used to forward a mouse event to a pane.
|
|
.Pp
|
|
The default key bindings allow the mouse to be used to select and resize panes,
|
|
to copy text and to change window using the status line.
|
|
These take effect if the
|
|
.Ic mouse
|
|
option is turned on.
|
|
.Sh FORMATS
|
|
Certain commands accept the
|
|
.Fl F
|
|
flag with a
|
|
.Ar format
|
|
argument.
|
|
This is a string which controls the output format of the command.
|
|
Replacement variables are enclosed in
|
|
.Ql #{
|
|
and
|
|
.Ql } ,
|
|
for example
|
|
.Ql #{session_name} .
|
|
The possible variables are listed in the table below, or the name of a
|
|
.Nm
|
|
option may be used for an option's value.
|
|
Some variables have a shorter alias such as
|
|
.Ql #S ;
|
|
.Ql ##
|
|
is replaced by a single
|
|
.Ql # ,
|
|
.Ql #,
|
|
by a
|
|
.Ql \&,
|
|
and
|
|
.Ql #}
|
|
by a
|
|
.Ql } .
|
|
.Pp
|
|
Conditionals are available by prefixing with
|
|
.Ql \&?
|
|
and separating two alternatives with a comma;
|
|
if the specified variable exists and is not zero, the first alternative
|
|
is chosen, otherwise the second is used.
|
|
For example
|
|
.Ql #{?session_attached,attached,not attached}
|
|
will include the string
|
|
.Ql attached
|
|
if the session is attached and the string
|
|
.Ql not attached
|
|
if it is unattached, or
|
|
.Ql #{?automatic-rename,yes,no}
|
|
will include
|
|
.Ql yes
|
|
if
|
|
.Ic automatic-rename
|
|
is enabled, or
|
|
.Ql no
|
|
if not.
|
|
Conditionals can be nested arbitrarily.
|
|
Inside a conditional,
|
|
.Ql \&,
|
|
and
|
|
.Ql }
|
|
must be escaped as
|
|
.Ql #,
|
|
and
|
|
.Ql #} ,
|
|
unless they are part of a
|
|
.Ql #{...}
|
|
replacement.
|
|
For example:
|
|
.Bd -literal -offset indent
|
|
#{?pane_in_mode,#[fg=white#,bg=red],#[fg=red#,bg=white]}#W .
|
|
.Ed
|
|
.Pp
|
|
Comparisons may be expressed by prefixing two comma-separated
|
|
alternatives by
|
|
.Ql ==
|
|
or
|
|
.Ql !=
|
|
and a colon.
|
|
For example
|
|
.Ql #{==:#{host},myhost}
|
|
will be replaced by
|
|
.Ql 1
|
|
if running on
|
|
.Ql myhost ,
|
|
otherwise by
|
|
.Ql 0 .
|
|
An
|
|
.Ql m
|
|
specifies an
|
|
.Xr fnmatch 3
|
|
comparison where the first argument is the pattern and the second the string to
|
|
compare, for example
|
|
.Ql #{m:*foo*,#{host}} .
|
|
.Ql ||
|
|
and
|
|
.Ql &&
|
|
evaluate to true if either or both of two comma-separated alternatives are
|
|
true, for example
|
|
.Ql #{||:#{pane_in_mode},#{alternate_on}} .
|
|
A
|
|
.Ql C
|
|
performs a search for an
|
|
.Xr fnmatch 3
|
|
pattern in the pane content and evaluates to zero if not found, or a line
|
|
number if found.
|
|
.Pp
|
|
A limit may be placed on the length of the resultant string by prefixing it
|
|
by an
|
|
.Ql = ,
|
|
a number and a colon.
|
|
Positive numbers count from the start of the string and negative from the end,
|
|
so
|
|
.Ql #{=5:pane_title}
|
|
will include at most the first 5 characters of the pane title, or
|
|
.Ql #{=-5:pane_title}
|
|
the last 5 characters.
|
|
Prefixing a time variable with
|
|
.Ql t:
|
|
will convert it to a string, so if
|
|
.Ql #{window_activity}
|
|
gives
|
|
.Ql 1445765102 ,
|
|
.Ql #{t:window_activity}
|
|
gives
|
|
.Ql Sun Oct 25 09:25:02 2015 .
|
|
The
|
|
.Ql b:
|
|
and
|
|
.Ql d:
|
|
prefixes are
|
|
.Xr basename 3
|
|
and
|
|
.Xr dirname 3
|
|
of the variable respectively.
|
|
.Ql q:
|
|
will escape
|
|
.Xr sh 1
|
|
special characters.
|
|
.Ql E:
|
|
will expand the format twice, for example
|
|
.Ql #{E:status-left}
|
|
is the result of expanding the content of the
|
|
.Ic status-left
|
|
option rather than the content itself.
|
|
.Ql T:
|
|
is like
|
|
.Ql E:
|
|
but also expands
|
|
.Xr strftime 3
|
|
specifiers.
|
|
.Ql S: ,
|
|
.Ql W:
|
|
or
|
|
.Ql P:
|
|
will loop over each session, window or pane and insert the format once
|
|
for each.
|
|
For windows and panes, two comma-separated formats may be given:
|
|
the second is used for the current window or active pane.
|
|
For example, to get a list of windows formatted like the status line:
|
|
.Bd -literal -offset indent
|
|
#{W:#{E:window-status-format} ,#{E:window-status-current-format} }
|
|
.Ed
|
|
.Pp
|
|
A prefix of the form
|
|
.Ql s/foo/bar/:
|
|
will substitute
|
|
.Ql foo
|
|
with
|
|
.Ql bar
|
|

In addition, the first line of a shell command's output may be inserted using
|
|
.Ql #() .
|
|
For example,
|
|
.Ql #(uptime)
|
|
will insert the system's uptime.
|
|
When constructing formats,
|
|
.Nm
|
|
does not wait for
|
|
.Ql #()
|
|
commands to finish; instead, the previous result from running the same command is used,
|
|
or a placeholder if the command has not been run before.
|
|
If the command hasn't exited, the most recent line of output will be used, but the status
|
|
line will not be updated more than once a second.
|

Commands are executed with the

.Sh NAMES AND TITLES
|
|
.Nm
|
|
distinguishes between names and titles.
|
|
Windows and sessions have names, which may be used to specify them in targets
|
|
and are displayed in the status line and various lists: the name is the
|
|
.Nm
|
|
identifier for a window or session.
|
|
Only panes have titles.
|
|
A pane's title is typically set by the program running inside the pane using
|
|
an escape sequence (like it would set the
|
|
.Xr xterm 1
|
|
window title in
|
|
.Xr X 7 ) .
|
|
Windows themselves do not have titles - a window's title is the title of its
|
|
active pane.
|
|
.Nm
|
|
itself may set the title of the terminal in which the client is running, see
|
|
the
|
|
.Ic set-titles
|
|
option.
|
|
.Pp
|
|
A session's name is set with the
|
|
.Ic new-session
|
|
and
|
|
.Ic rename-session
|
|
commands.
|
|
A window's name is set with one of:
|
|
.Bl -enum -width Ds
|
|
.It
|
|
A command argument (such as
|
|
.Fl n
|
|
for
|
|
.Ic new-window
|
|
or
|
|
.Ic new-session ) .
|
|
.It
|
|
An escape sequence (if the
|
|
.Ic allow-rename
|
|
option is turned on):
|
|
.Bd -literal -offset indent
|
|
$ printf '\e033kWINDOW_NAME\e033\e\e'
|
|
.Ed
|
|
.It
|
|
Automatic renaming, which sets the name to the active command in the window's
|
|
active pane.
|
|
See the
|
|
.Ic automatic-rename
|
|
option.
|
|
.El
|
|
.Pp
|
|
When a pane is first created, its title is the hostname.
|
|
A pane's title can be set via the title setting escape sequence, for example:
|
|
.Bd -literal -offset indent
|
|
$ printf '\e033]2;My Title\e033\e\e'
|
|
.Ed
|
|
.Pp
|
|
It can also be modified with the
|
|
.Ic select-pane
|
|
.Fl T
|
|
command.
|
|
.Sh GLOBAL AND SESSION ENVIRONMENT
|
|
When the server is started,
|
|
.Nm
|
|
copies the environment into the
|
|
.Em global environment ;
|
|
in addition, each session has a
|
|
.Em session environment .
|
|
When a window is created, the session and global environments are merged.
|
|
If a variable exists in both, the value from the session environment is used.
|
|
The result is the initial environment passed to the new process.
|
|
.Pp
|
|
The
|
|
.Ic update-environment
|
|
session option may be used to update the session environment from the client
|
|
when a new session is created or an old reattached.
|
|
.Nm
|
|
also initialises the
|
|
.Ev TMUX
|
|
variable with some internal information to allow commands to be executed
|
|
from inside, and the
|
|
.Ev TERM
|
|
variable with the correct terminal setting of
|
|
.Ql screen .
|
|
.Pp
|
|
Commands to alter and view the environment are:
|
|
.Bl -tag -width Ds
|
|
.It Xo Ic set-environment
|
|
.Op Fl gru
|
|
.Op Fl t Ar target-session
|
|
.Ar name Op Ar value
|
|
.Xc
|
|
.D1 (alias: Ic setenv )
|
|
Set or unset an environment variable.
|
|
If
|
|
.Fl g
|
|
is used, the change is made in the global environment; otherwise, it is applied
|
|
to the session environment for
|
|
.Ar target-session .
|
|
The
|
|
.Fl u
|
|
flag unsets a variable.
|
|
.Fl r
|
|
indicates the variable is to be removed from the environment before starting a
|
|
new process.
|
|
.It Xo Ic show-environment
|
|
.Op Fl gs
|
|
.Op Fl t Ar target-session
|
|
.Op Ar variable
|
|
.Xc
|
|
.D1 (alias: Ic showenv )
|
|
Display the environment for
|
|
.Ar target-session
|
|
or the global environment with
|
|
.Fl g .
|
|
If
|
|
.Ar variable
|
|
is omitted, all variables are shown.
|
|
Variables removed from the environment are prefixed with
|
|
.Ql - .
|
|
If
|
|
.Fl s
|
|
is used, the output is formatted as a set of Bourne shell commands.
|
|
.El
|
|
.Sh STATUS LINE
|
|
.Nm
|
|
includes an optional status line which is displayed in the bottom line of each
|
|
terminal.
|
|
.Pp
|
|
By default, the status line is enabled and one line in height (it may be
|
|
disabled or made multiple lines 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 title of the active pane
|
|
in double quotes; and the time and date.
|
|
.Pp
|
|
Each line of the status line is configured with the
|
|
.Ic status-format
|
|
option.
|
|
The default 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.
|
|
By default, the window list shows the index, name and (if any) flag of the
|
|
windows present in the current session in ascending numerical order.
|
|
It may be customised with the
|
|
.Ar window-status-format
|
|
and
|
|
.Ar window-status-current-format
|
|
options.
|
|
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 activity is monitored and activity has been detected."
|
|
.It Li "\&!" Ta "Window bells are monitored and a bell has occurred in the window."
|
|
.It Li "~" Ta "The window has been silent for the monitor-silence interval."
|
|
.It Li "M" Ta "The window contains the marked pane."
|
|
.It Li "Z" Ta "The window's active pane is zoomed."
|
|
.El
|
|
.Pp
|
|
The # symbol relates to the
|
|
.Ic monitor-activity
|
|
window option.
|
|
The window name is printed in inverted colours if an alert (bell, activity or
|
|
silence) is present.

|
|
.Nm
|
|
maintains a set of named

|
|
Each buffer may be either explicitly or automatically named.
|
|
Explicitly named buffers are named when created with the
|
|
.Ic set-buffer
|
|
or
|
|
.Ic load-buffer
|
|
commands, or by renaming an automatically named buffer with
|
|
.Ic set-buffer
|
|
.Fl n .
|
|
Automatically named buffers are given a name such as
|
|
.Ql buffer0001 ,
|
|
.Ql buffer0002
|
|
and so on.
|
|
When the
|
|
.Ic buffer-limit
|
|
option is reached, the oldest automatically named buffer is deleted.
|
|
Explicitly named buffers are not subject to
|
|
.Ic buffer-limit
|
|
and may be deleted with
|
|
.Ic delete-buffer
|
|
command.
|
|

.Ic set-buffer
|
|
and
|
|
.Ic load-buffer
|
|
commands, and pasted into a window using the
|
|
.Ic paste-buffer
|
|
command.
|
|
If a buffer command is used and no buffer is specified, the most
|
|
recently added automatically named buffer is assumed.
|
|
.Pp
|
|
A configurable history buffer is also maintained for each window.
|
|
By default, up to 2000 lines are kept; this can be altered with the
|
|
.Ic history-limit
|
|
option (see the
|
|
.Ic set-option
|
|
command above).
|

|
.Ar template
|
|
and the result executed as a command.
|
|
If

|
.Fl f
|
|
specifies an initial filter: the filter is a format - if it evaluates to zero,
|
|
the item in the list is not shown, otherwise it is shown.
|
|
If a filter would lead to an empty list, it is ignored.
|
|
.Fl F
|
|
specifies the format for each item in the list.
|
|
.Fl N

.Sh ENVIRONMENT
|
|
When
|
|
.Nm
|
|
is started, it inspects the following environment variables:
|
|
.Bl -tag -width LC_CTYPE
|
|
.It Ev EDITOR
|
|
If the command specified in this variable contains the string
|
|
.Ql vi
|
|
and
|
|
.Ev VISUAL
|
|
is unset, use vi-style key bindings.
|
|
Overridden by the

|
|
and
|
|
.Ic status-keys
|
|
options.
|
|
.It Ev HOME
|
|
The user's login directory.
|
|
If unset, the
|
|
.Xr passwd 5
|
|
database is consulted.
|
|
.It Ev LC_CTYPE
|
|
The character encoding
|
|
.Xr locale 1 .
|
|
It is used for two separate purposes.
|
|
For output to the terminal, UTF-8 is used if the
|
|
.Fl u
|
|
option is given or if
|
|
.Ev LC_CTYPE
|
|
contains
|
|
.Qq UTF-8
|
|
or
|
|
.Qq UTF8 .
|
|
Otherwise, only ASCII characters are written and non-ASCII characters
|
|
are replaced with underscores
|
|
.Pq Ql _ .
|
|
For input,
|
|
.Nm
|
|
always runs with a UTF-8 locale.
|
|
If en_US.UTF-8 is provided by the operating system it is used and
|
|
.Ev LC_CTYPE
|
|
is ignored for input.
|
|
Otherwise,
|
|
.Ev LC_CTYPE
|
|
tells
|
|
.Nm
|
|
what the UTF-8 locale is called on the current system.
|
|
If the locale specified by
|
|
.Ev LC_CTYPE
|
|
is not available or is not a UTF-8 locale,
|
|
.Nm
|
|
exits with an error message.
|
|
.It Ev LC_TIME
|
|
The date and time format
|
|
.Xr locale 1 .
|
|
It is used for locale-dependent
|
|
.Xr strftime 3
|
|
format specifiers.
|
|
.It Ev PWD
|
|
The current working directory to be set in the global environment.
|
|
This may be useful if it contains symbolic links.
|
|
If the value of the variable does not match the current working
|
|
directory, the variable is ignored and the result of
|
|
.Xr getcwd 3
|
|
is used instead.
|
|
.It Ev SHELL
|
|
The absolute path to the default shell for new windows.
|
|
See the
|
|
.Ic default-shell
|
|
option for details.
|
|
.It Ev TMUX_TMPDIR
|
|
The parent directory of the directory containing the server sockets.
|
|
See the
|
|
.Fl L
|
|
option for details.
|
|
.It Ev VISUAL
|
|
If the command specified in this variable contains the string
|
|
.Ql vi ,
|
|
use vi-style key bindings.

session running
|
|
.Xr vi 1 :
|
|
.Pp
|
|
.Dl $ tmux new-session vi
|
|
.Pp
|
|
Most commands have a shorter form, known as an alias.
|
|
For new-session, this is
|
|
.Ic new :
|
|
.Pp
|
|
.Dl $ tmux new vi
|
|
.Pp
|
|
Alternatively, the shortest unambiguous form of a command is accepted.
|
|
If there are several options, they are listed:
|
|
.Bd -literal -offset indent
|
|
$ tmux n
|
|
ambiguous command: n, could be: new-session, new-window, next-window
|
|
.Ed
|
|
.Pp
|
|
Within an active session, a new window may be created by typing
|
|
.Ql C-b c
|
|
(Ctrl
|
|
followed by the
|
|
.Ql b
|
|
key
|
|
followed by the
|
|
.Ql c
|
|
key).
|
|
.Pp
|
|
Windows may be navigated with:
|
|
.Ql C-b 0
|
|
(to select window 0),
|
|
.Ql C-b 1
|
|
(to select window 1), and so on;
|
|
.Ql C-b n
|
|
to select the next window; and
|
|
.Ql C-b p
|
|
to select the previous window.
|
|
.Pp
|
|
A session may be detached using
|
|
.Ql C-b d
|
|
(or by an external event such as
|
|
.Xr ssh 1
|
|
disconnection) and reattached with:
|
|
.Pp
|
|
.Dl $ tmux attach-session
|
|
.Pp
|
|
Typing
|
|
.Ql C-b \&?
|
|
lists the current key bindings in the current window; up and down may be used
|
|
to navigate the list or
|
|
.Ql q
|
|
to exit from it.
|
|
.Pp
|
|
Commands to be run when the
|
|
.Nm
|
|
server is started may be placed in the
|
|
.Pa ~/.tmux.conf
|
|
configuration file.
|
|
