     tmux -- terminal multiplexer

     tmux [-28lquvV] [-c shell-command]	[-f file] [-L socket-name]
	  [-S socket-path] [command [flags]]

     tmux is a terminal	multiplexer: it	enables	a number of terminals to be
     created, accessed,	and controlled from a single screen.  tmux may be de-
     tached from a screen and continue running in the background, then later

     When tmux is started it creates a new session with	a single 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 com-

     A session is a single collection of pseudo	terminals under	the management
     of	tmux.  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 pty(4)	manual page documents
     the technical details of pseudo terminals).  Any number of	tmux instances
     may connect to the	same session, and any number of	windows	may be present
     in	the same session.  Once	all sessions are killed, tmux exits.

     Each session is persistent	and will survive accidental disconnection
     (such as ssh(1) connection	timeout) or intentional	detaching (with	the
     `C-b d' key strokes).  tmux may be	reattached using:

	   $ tmux attach

     In	tmux, a	session	is displayed on	screen by a client and all sessions
     are managed by a single server.  The server and each client are separate
     processes which communicate through a socket in /tmp.

     The options are as	follows:

     -2		   Force tmux to assume	the terminal supports 256 colours.

     -8		   Like	-2, but	indicates that the terminal supports 88

     -c	shell-command
		   Execute shell-command using the default shell.  If neces-
		   sary, the tmux server will be started to retrieve the
		   default-shell option.  This option is for compatibility
		   with	sh(1) when tmux	is used	as a login shell.

     -f	file	   Specify an alternative configuration	file.  By default,
		   tmux	loads the system configuration file from
		   /etc/tmux.conf, if present, then looks for a	user configu-
		   ration file at ~/.tmux.conf.	 The configuration file	is a
		   set of tmux commands	which are executed in sequence when
		   the server is first started.

		   If a	command	in the configuration file fails, tmux will re-
		   port	an error and exit without executing further commands.

     -L	socket-name
		   tmux	stores the server socket in a directory	under /tmp (or
		   TMPDIR if set); the default socket is named default.	 This
		   option allows a different socket name to be specified, al-
		   lowing several independent tmux servers to be run.  Unlike
		   -S a	full path is not necessary: the	sockets	are all	cre-
		   ated	in the same directory.

		   If the socket is accidentally removed, the SIGUSR1 signal
		   may be sent to the tmux server process to recreate it.

     -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.

     -q		   Set the quiet server	option to prevent the server sending
		   various informational messages.

     -S	socket-path
		   Specify a full alternative path to the server socket.  If
		   -S is specified, the	default	socket directory is not	used
		   and any -L flag is ignored.

     -u		   tmux	attempts to guess if the terminal is likely to support
		   UTF-8 by checking the first of the LC_ALL, LC_CTYPE and
		   LANG	environment variables to be set	for the	string
		   "UTF-8".  This is not always	correct: the -u	flag explic-
		   itly	informs	tmux that UTF-8	is supported.

		   If the server is started from a client passed -u or where
		   UTF-8 is detected, the utf8 and status-utf8 options are en-
		   abled in the	global window and session options respec-

     -v		   Request verbose logging.  This option may be	specified mul-
		   tiple times for increasing verbosity.  Log messages will be
		   saved into tmux-client-PID.log and tmux-server-PID.log
		   files in the	current	directory, where PID is	the PID	of the
		   server or client process.

     -V		   Report the tmux version.

     command [flags]
		   This	specifies one of a set of commands used	to control
		   tmux, as described in the following sections.  If no	com-
		   mands are specified,	the new-session	command	is assumed.

     tmux may be controlled from an attached client by using a key combination
     of	a prefix key, `C-b' (Ctrl-b) by	default, followed by a command key.

     The default command key bindings are:

	   C-b	       Send the	prefix key (C-b) through to the	application.
	   C-o	       Rotate the panes	in the current window forwards.
	   C-z	       Suspend the tmux	client.
	   !	       Break the current pane out of the window.
	   "	       Split the current pane into two,	top and	bottom.
	   #	       List all	paste buffers.
	   $	       Rename the current session.
	   %	       Split the current pane into two,	left and right.
	   &	       Kill the	current	window.
	   '	       Prompt for a window index to select.
	   ,	       Rename the current window.
	   -	       Delete the most recently	copied buffer of text.
	   .	       Prompt for an index to move the current window.
	   0 to	9      Select windows 0	to 9.
	   :	       Enter the tmux command prompt.
	   ;	       Move to the previously active pane.
	   =	       Choose which buffer to paste interactively from a list.
	   ?	       List all	key bindings.
	   D	       Choose a	client to detach.
	   [	       Enter copy mode to copy text or view the	history.
	   ]	       Paste the most recently copied buffer of	text.
	   c	       Create a	new window.
	   d	       Detach the current client.
	   f	       Prompt to search	for text in open windows.
	   i	       Display some information	about the current window.
	   l	       Move to the previously selected window.
	   n	       Change to the next window.
	   o	       Select the next pane in the current window.
	   p	       Change to the previous window.
	   q	       Briefly display pane indexes.
	   r	       Force redraw of the attached client.
	   s	       Select a	new session for	the attached client interac-
	   L	       Switch the attached client back to the last session.
	   t	       Show the	time.
	   w	       Choose the current window interactively.
	   x	       Kill the	current	pane.
	   {	       Swap the	current	pane with the previous pane.
	   }	       Swap the	current	pane with the next pane.
	   ~	       Show previous messages from tmux, if any.
	   Page	Up     Enter copy mode and scroll one page up.
	   Up, Down
	   Left, Right
		       Change to the pane above, below,	to the left, or	to the
		       right of	the current pane.
	   M-1 to M-5  Arrange panes in	one of the five	preset layouts:	even-
		       horizontal, even-vertical, main-horizontal, main-verti-
		       cal, or tiled.
	   M-n	       Move to the next	window with a bell or activity marker.
	   M-o	       Rotate the panes	in the current window backwards.
	   M-p	       Move to the previous window with	a bell or activity
	   C-Up, C-Down
	   C-Left, C-Right
		       Resize the current pane in steps	of one cell.
	   M-Up, M-Down
	   M-Left, M-Right
		       Resize the current pane in steps	of five	cells.

     Key bindings may be changed with the bind-key and unbind-key commands.

     This section contains a list of the commands supported by tmux.  Most
     commands accept the optional -t argument with one of target-client,
     target-session target-window, or target-pane.  These specify the client,
     session, window or	pane which a command should affect.  target-client is
     the name of the pty(4) file to which the client is	connected, for example
     either of /dev/ttyp1 or ttyp1 for the client attached to /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	list-clients command.

     target-session is either the name of a session (as	listed by the
     list-sessions command) or the name	of a client with the same syntax as
     target-client, in which case the session attached to the client is	used.
     When looking for the session name,	tmux initially searches	for an exact
     match; if none is found, the session names	are checked for	any for	which
     target-session is a prefix	or for which it	matches	as an fnmatch(3) pat-
     tern.  If a single	match is found,	it is used as the target session; mul-
     tiple 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.

     target-window specifies a window in the form session:window.  session
     follows the same rules as for target-session, and 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 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 ex-
     ample the new-window and link-window commands) otherwise the current win-
     dow in session is chosen.	The special character `!' uses the last	(pre-
     viously current) window, or `+' and `-' are the next window or the	previ-
     ous window	by number.  When the argument does not contain a colon,	tmux
     first attempts to parse it	as window; if that fails, an attempt is	made
     to	match a	session.

     target-pane takes a similar form to target-window but with	the optional
     addition of a period followed by a	pane index, for	example: mysession:my-
     window.1.	If the pane index is omitted, the currently active pane	in the
     specified window is used.	If neither a colon nor period appears, tmux
     first attempts to use the argument	as a pane index; if that fails,	it is
     looked up as for target-window.  A	`+' or `-' indicate the	next or	previ-
     ous pane index, respectively.  One	of the strings top, bottom, left,
     right, top-left, top-right, bottom-left or	bottom-right may be used in-
     stead of a	pane index.

     The special characters `+'	and `-'	may be followed	by an offset, for ex-

	   select-window -t:+2

     When dealing with a session that doesn't contain sequential window	in-
     dexes, they will be correctly skipped.

     tmux also gives each pane created in a server an identifier consisting of
     a `%' and a number, starting from zero.  A	pane's identifier is unique
     for the life of the tmux server and is passed to the child	process	of the
     pane in the TMUX_PANE environment variable.  It may be used alone to tar-
     get a pane	or the window containing it.

     shell-command arguments are sh(1) commands.  These	must be	passed as a
     single item, which	typically means	quoting	them, for example:

	   new-window 'vi /etc/passwd'

     command [arguments] refers	to a tmux command, passed with the command and
     arguments separately, for example:

	   bind-key F1 set-window-option force-width 81

     Or	if using sh(1):

	   $ tmux bind-key F1 set-window-option	force-width 81

     Multiple commands may be specified	together as part of a command
     sequence.	Each command should be separated by spaces and a semicolon;
     commands are executed sequentially	from left to right.  A literal semi-
     colon may be included by escaping it with a backslash (for	example, when
     specifying	a command sequence to bind-key).

     Example tmux commands include:

	   refresh-client -t/dev/ttyp2

	   rename-session -tfirst newname

	   set-window-option -t:0 monitor-activity on

	   new-window ;	split-window -d

     Or	from sh(1):

	   $ tmux kill-window -t :1

	   $ tmux new-window \;	split-window -d

	   $ tmux new-session -d 'vi /etc/passwd' \; split-window -d \;	attach

     The tmux server manages clients, sessions,	windows	and panes.  Clients
     are attached to sessions to interact with them, either when they are cre-
     ated with the new-session command,	or later with the attach-session com-
     mand.  Each session has one or more windows 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 WINDOWS AND PANES sec-

     The following commands are	available to manage clients and	sessions:

     attach-session [-dr] [-t target-session]
		   (alias: attach)
	     If	run from outside tmux, create a	new client in the current ter-
	     minal and attach it to target-session.  If	used from inside,
	     switch the	current	client.	 If -d is specified, any other clients
	     attached to the session are detached.  -r signifies the client is
	     read-only (only keys bound	to the detach-client command have any

	     If	no server is started, attach-session will attempt to start it;
	     this will fail unless sessions are	created	in the configuration

	     The target-session	rules for attach-session are slightly ad-
	     justed: if	tmux needs to select the most recently used session,
	     it	will prefer the	most recently used unattached session.

     detach-client [-P]	[-s target-session] [-t	target-client]
		   (alias: detach)
	     Detach the	current	client if bound	to a key, the client specified
	     with -t, or all clients currently attached	to to the session
	     specified by -s.  If -P is	given, send SIGHUP to the parent
	     process of	the client, typically causing it to exit.

     has-session [-t target-session]
		   (alias: has)
	     Report an error and exit with 1 if	the specified session does not
	     exist.  If	it does	exist, exit with 0.

	     Kill the tmux server and clients and destroy all sessions.

     kill-session [-t target-session]
	     Destroy the given session,	closing	any windows linked to it and
	     no	other sessions,	and detaching all clients attached to it.

     list-clients [-t target-session]
		   (alias: lsc)
	     List all clients attached to the server.  If target-session is
	     specified,	list only clients connected to that session.

		   (alias: lscm)
	     List the syntax of	all commands supported by tmux.

		   (alias: ls)
	     List all sessions managed by the server.

     lock-client [-t target-client]
		   (alias: lockc)
	     Lock target-client, see the lock-server command.

     lock-session [-t target-session]
		   (alias: locks)
	     Lock all clients attached to target-session.

     new-session [-d] [-n window-name] [-s session-name] [-t target-session]
	     [-x width]	[-y height] [shell-command]
		   (alias: new)
	     Create a new session with name session-name.

	     The new session is	attached to the	current	terminal unless	-d is
	     given.  window-name and shell-command are the name	of and shell
	     command to	execute	in the initial window.	If -d is used, -x and
	     -y	specify	the size of the	initial	window (80 by 24 if not

	     If	run from a terminal, any termios(4) special characters are
	     saved and used for	new windows in the new session.

	     If	-t is given, the new session is	grouped	with target-session.
	     This means	they share the same set	of windows - all windows from
	     target-session are	linked to the new session and any subsequent
	     new windows or windows being closed are applied to	both sessions.
	     The current and previous window and any session options remain
	     independent and either session may	be killed without affecting
	     the other.	 Giving	-n or shell-command are	invalid	if -t is used.

     refresh-client [-t	target-client]
		   (alias: refresh)
	     Refresh the current client	if bound to a key, or a	single client
	     if	one is given with -t.

     rename-session [-t	target-session]	new-name
		   (alias: rename)
	     Rename the	session	to new-name.

     show-messages [-t target-client]
		   (alias: showmsgs)
	     Any messages displayed on the status line are saved in a per-
	     client message log, up to a maximum of the	limit set by the
	     message-limit session option for the session attached to that
	     client.  This command displays the	log for	target-client.

     source-file path
		   (alias: source)
	     Execute commands from path.

		   (alias: start)
	     Start the tmux server, if not already running, without creating
	     any sessions.

     suspend-client [-t	target-client]
		   (alias: suspendc)
	     Suspend a client by sending SIGTSTP (tty stop).

     switch-client [-lnp] [-c target-client] [-t target-session]
		   (alias: switchc)
	     Switch the	current	session	for client target-client to
	     target-session.  If -l, -n	or -p is used, the client is moved to
	     the last, next or previous	session	respectively.

     A tmux window may be in one of several 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
     paste buffer for later insertion into another window.  This mode is en-
     tered with	the copy-mode command, bound to	`[' by default.	 It is also
     entered when a command that produces output, such as list-keys, is	exe-
     cuted from	a key binding.

     The keys available	depend on whether emacs	or vi mode is selected (see
     the mode-keys option).  The following keys	are supported as appropriate
     for the mode:

	   Function			vi		emacs
	   Back	to indentation		^		M-m
	   Bottom of history		G		M-<
	   Clear selection		Escape		C-g
	   Copy	selection		Enter		M-w
	   Cursor down			j		Down
	   Cursor left			h		Left
	   Cursor right			l		Right
	   Cursor to bottom line	L
	   Cursor to middle line	M		M-r
	   Cursor to top line		H		M-R
	   Cursor up			k		Up
	   Delete entire line		d		C-u
	   Delete/Copy to end of line	D		C-k
	   End of line			$		C-e
	   Go to line			:		g
	   Half	page down		C-d		M-Down
	   Half	page up			C-u		M-Up
	   Jump	forward			f		f
	   Jump	backward		F		F
	   Jump	again			;		;
	   Jump	again in reverse	,		,
	   Next	page			C-f		Page down
	   Next	space			W
	   Next	space, end of word	E
	   Next	word			w
	   Next	word end		e		M-f
	   Paste buffer			p		C-y
	   Previous page		C-b		Page up
	   Previous word		b		M-b
	   Previous space		B
	   Quit	mode			q		Escape
	   Rectangle toggle		v		R
	   Scroll down			C-Down or C-e	C-Down
	   Scroll up			C-Up or	C-y	C-Up
	   Search again			n		n
	   Search again	in reverse	N		N
	   Search backward		?		C-r
	   Search forward		/		C-s
	   Start of line		0		C-a
	   Start selection		Space		C-Space
	   Top of history		g		M->
	   Transpose chars				C-t

     The next and previous word	keys use space and the `-', `_'	and `@'	char-
     acters as word delimiters by default, but this can	be adjusted by setting
     the word-separators window	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.

     The jump commands enable quick movement within a line.  For instance,
     typing `f'	followed by `/'	will move the cursor to	the next `/' character
     on	the current line.  A `;' will then jump	to the next occurrence.

     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.  For example,	to
     move the cursor forward by	ten words, use `M-1 0 M-f' in emacs mode, and
     `10w' in vi.

     Mode key bindings are defined in a	set of named tables: vi-edit and
     emacs-edit	for keys used when line	editing	at the command prompt;
     vi-choice and emacs-choice	for keys used when choosing from lists (such
     as	produced by the	choose-window command);	and vi-copy and	emacs-copy
     used in copy mode.	 The tables may	be viewed with the list-keys command
     and keys modified or removed with bind-key	and unbind-key.

     The paste buffer key pastes the first line	from the top paste buffer on
     the stack.

     The synopsis for the copy-mode command is:

     copy-mode [-u] [-t	target-pane]
	     Enter copy	mode.  The -u option scrolls one page up.

     Each window displayed by tmux may be split	into one or more 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	split-window command.  Windows
     may be split horizontally (with the -h flag) or vertically.  Panes	may be
     resized with the resize-pane command (bound to `C-up', `C-down' `C-left'
     and `C-right' by default),	the current pane may be	changed	with the
     select-pane command and the rotate-window and 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.

     A number of preset	layouts	are available.	These may be selected with the
     select-layout command or cycled with next-layout (bound to	`Space'	by de-
     fault); once a layout is chosen, panes within it may be moved and resized
     as	normal.

     The following layouts are supported:

	     Panes are spread out evenly from left to right across the window.

	     Panes are spread evenly from top to bottom.

	     A large (main) pane is shown at the top of	the window and the re-
	     maining panes are spread from left	to right in the	leftover space
	     at	the bottom.  Use the main-pane-height window option to specify
	     the height	of the top pane.

	     Similar to	main-horizontal	but the	large pane is placed on	the
	     left and the others spread	from top to bottom along the right.
	     See the main-pane-width window option.

     tiled   Panes are spread out as evenly as possible	over the window	in
	     both rows and columns.

     In	addition, select-layout	may be used to apply a previously used layout
     - the list-windows	command	displays the layout of each window in a	form
     suitable for use with select-layout.  For example:

	   $ 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}

     tmux 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.

     Commands related to windows and panes are as follows:

     break-pane	[-d] [-t target-pane]
		   (alias: breakp)
	     Break target-pane off from	its containing window to make it the
	     only pane in a new	window.	 If -d is given, the new window	does
	     not become	the current window.

     capture-pane [-b buffer-index] [-E	end-line] [-S start-line] [-t
		   (alias: capturep)
	     Capture the contents of a pane to the specified buffer, or	a new
	     buffer if none is specified.

	     -S	and -E specify the starting and	ending line numbers, zero is
	     the first line of the visible pane	and negative numbers are lines
	     in	the history.  The default is to	capture	only the visible con-
	     tents of the pane.

     choose-client [-t target-window] [template]
	     Put a window into client choice mode, allowing a client to	be se-
	     lected interactively from a list.	After a	client is chosen, `%%'
	     is	replaced by the	client pty(4) path in template and the result
	     executed as a command.  If	template is not	given, "detach-client
	     -t	'%%'" is used.	This command works only	from inside tmux.

     choose-session [-t	target-window] [template]
	     Put a window into session choice mode, where a session may	be se-
	     lected interactively from a list.	When one is chosen, `%%' is
	     replaced by the session name in template and the result executed
	     as	a command.  If template	is not given, "switch-client -t	'%%'"
	     is	used.  This command works only from inside tmux.

     choose-window [-t target-window] [template]
	     Put a window into window choice mode, where a window may be cho-
	     sen interactively from a list.  After a window is selected, `%%'
	     is	replaced by the	session	name and window	index in template and
	     the result	executed as a command.	If template is not given, "se-
	     lect-window -t '%%'" is used.  This command works only from in-
	     side tmux.

     display-panes [-t target-client]
		   (alias: displayp)
	     Display a visible indicator of each pane shown by target-client.
	     See the display-panes-time, display-panes-colour, and
	     display-panes-active-colour session options.  While the indicator
	     is	on screen, a pane may be selected with the `0' to `9' keys.

     find-window [-t target-window] match-string
		   (alias: findw)
	     Search for	the fnmatch(3) pattern match-string in window names,
	     titles, and visible content (but not history).  If	only one win-
	     dow is matched, it'll be automatically selected, otherwise	a
	     choice list is shown.  This command only works from inside	tmux.

     join-pane [-dhv] [-l size | -p percentage]	[-s src-pane] [-t dst-pane]
		   (alias: joinp)
	     Like split-window,	but instead of splitting dst-pane and creating
	     a new pane, split it and move src-pane into the space.  This can
	     be	used to	reverse	break-pane.

     kill-pane [-a] [-t	target-pane]
		   (alias: killp)
	     Destroy the given pane.  If no panes remain in the	containing
	     window, it	is also	destroyed.  The	-a option kills	all but	the
	     pane given	with -t.

     kill-window [-t target-window]
		   (alias: killw)
	     Kill the current window or	the window at target-window, removing
	     it	from any sessions to which it is linked.

     last-pane [-t target-window]
		   (alias: lastp)
	     Select the	last (previously selected) pane.

     last-window [-t target-session]
		   (alias: last)
	     Select the	last (previously selected) window.  If no
	     target-session is specified, select the last window of the	cur-
	     rent session.

     link-window [-dk] [-s src-window] [-t dst-window]
		   (alias: linkw)
	     Link the window at	src-window to the specified dst-window.	 If
	     dst-window	is specified and no such window	exists,	the src-window
	     is	linked there.  If -k is	given and dst-window exists, it	is
	     killed, otherwise an error	is generated.  If -d is	given, the
	     newly linked window is not	selected.

     list-panes	[-as] [-t target]
		   (alias: lsp)
	     If	-a is given, target is ignored and all panes on	the server are
	     listed.  If -s is given, target is	a session (or the current ses-
	     sion).  If	neither	is given, target is a window (or the current

     list-windows [-a] [-t target-session]
		   (alias: lsw)
	     If	-a is given, list all windows on the server.  Otherwise, list
	     windows in	the current session or in target-session.

     move-window [-dk] [-s src-window] [-t dst-window]
		   (alias: movew)
	     This is similar to	link-window, except the	window at src-window
	     is	moved to dst-window.

     new-window	[-adkP]	[-n window-name] [-t target-window] [shell-command]
		   (alias: neww)
	     Create a new window.  With	-a, the	new window is inserted at the
	     next index	up from	the specified target-window, moving windows up
	     if	necessary, otherwise target-window is the new window location.

	     If	-d is given, the session does not make the new window the cur-
	     rent window.  target-window represents the	window to be created;
	     if	the target already exists an error is shown, unless the	-k
	     flag is used, in which case it is destroyed.  shell-command is
	     the command to execute.  If shell-command is not specified, the
	     value of the default-command option is used.

	     When the shell command completes, the window closes.  See the
	     remain-on-exit option to change this behaviour.

	     The TERM environment variable must	be set to "screen" for all
	     programs running inside tmux.  New	windows	will automatically
	     have "TERM=screen"	added to their environment, but	care must be
	     taken not to reset	this in	shell start-up files.

	     The -P option prints the location of the new window after it has
	     been created.

     next-layout [-t target-window]
		   (alias: nextl)
	     Move a window to the next layout and rearrange the	panes to fit.

     next-window [-a] [-t target-session]
		   (alias: next)
	     Move to the next window in	the session.  If -a is used, move to
	     the next window with a bell, activity or content alert.

     pipe-pane [-o] [-t	target-pane] [shell-command]
		   (alias: pipep)
	     Pipe any output sent by the program in target-pane	to a shell
	     command.  A pane may only be piped	to one command at a time, any
	     existing pipe is closed before shell-command is executed.	The
	     shell-command string may contain the special character sequences
	     supported by the status-left option.  If no shell-command is
	     given, the	current	pipe (if any) is closed.

	     The -o option only	opens a	new pipe if no previous	pipe exists,
	     allowing a	pipe to	be toggled with	a single key, for example:

		   bind-key C-p	pipe-pane -o 'cat >>~/output.#I-#P'

     previous-layout [-t target-window]
		   (alias: prevl)
	     Move to the previous layout in the	session.

     previous-window [-a] [-t target-session]
		   (alias: prev)
	     Move to the previous window in the	session.  With -a, move	to the
	     previous window with a bell, activity or content alert.

     rename-window [-t target-window] new-name
		   (alias: renamew)
	     Rename the	current	window,	or the window at target-window if
	     specified,	to new-name.

     resize-pane [-DLRU] [-t target-pane] [adjustment]
		   (alias: resizep)
	     Resize a pane, upward with	-U (the	default), downward with	-D, to
	     the left with -L and to the right with -R.	 The adjustment	is
	     given in lines or cells (the default is 1).

     respawn-pane [-k] [-t target-pane]	[shell-command]
		   (alias: respawnp)
	     Reactivate	a pane in which	the command has	exited (see the
	     remain-on-exit window option).  If	shell-command is not given,
	     the command used when the pane was	created	is executed.  The pane
	     must be already inactive, unless -k is given, in which case any
	     existing command is killed.

     respawn-window [-k] [-t target-window] [shell-command]
		   (alias: respawnw)
	     Reactivate	a window in which the command has exited (see the
	     remain-on-exit window option).  If	shell-command is not given,
	     the command used when the window was created is executed.	The
	     window must be already inactive, unless -k	is given, in which
	     case any existing command is killed.

     rotate-window [-DU] [-t target-window]
		   (alias: rotatew)
	     Rotate the	positions of the panes within a	window,	either upward
	     (numerically lower) with -U or downward (numerically higher).

     select-layout [-np] [-t target-window] [layout-name]
		   (alias: selectl)
	     Choose a specific layout for a window.  If	layout-name is not
	     given, the	last preset layout used	(if any) is reapplied.	-n and
	     -p	are equivalent to the next-layout and previous-layout com-

     select-pane [-lDLRU] [-t target-pane]
		   (alias: selectp)
	     Make pane target-pane the active pane in window target-window.
	     If	one of -D, -L, -R, or -U is used, respectively the pane	below,
	     to	the left, to the right,	or above the target pane is used.  -l
	     is	the same as using the last-pane	command.

     select-window [-lnp] [-t target-window]
		   (alias: selectw)
	     Select the	window at target-window.  -l, -n and -p	are equivalent
	     to	the last-window, next-window and previous-window commands.

     split-window [-dhvP] [-l size | -p	percentage] [-t	target-pane]
		   (alias: splitw)
	     Create a new pane by splitting target-pane: -h does a horizontal
	     split and -v a vertical split; if neither is specified, -v	is as-
	     sumed.  The -l and	-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.  All other options have the	same
	     meaning as	for the	new-window command.

     swap-pane [-dDU] [-s src-pane] [-t	dst-pane]
		   (alias: swapp)
	     Swap two panes.  If -U is used and	no source pane is specified
	     with -s, dst-pane is swapped with the previous pane (before it
	     numerically); -D swaps with the next pane (after it numerically).
	     -d	instructs tmux not to change the active	pane.

     swap-window [-d] [-s src-window] [-t dst-window]
		   (alias: swapw)
	     This is similar to	link-window, except the	source and destination
	     windows are swapped.  It is an error if no	window exists at

     unlink-window [-k]	[-t target-window]
		   (alias: unlinkw)
	     Unlink target-window.  Unless -k is given,	a window may be	un-
	     linked only if it is linked to multiple sessions -	windows	may
	     not be linked to no sessions; if -k is specified and the window
	     is	linked to only one session, it is unlinked and destroyed.

     tmux allows a command to be bound to most keys, with or without a prefix
     key.  When	specifying keys, most represent	themselves (for	example	`A' to
     `Z').  Ctrl keys may be prefixed with `C-'	or `^',	and Alt	(meta) with
     `M-'.  In addition, the following special key names are accepted: Up,
     Down, Left, Right,	BSpace,	BTab, DC (Delete), End,	Enter, Escape, F1 to
     F20, Home,	IC (Insert), NPage (Page Up), PPage (Page Down), Space,	and
     Tab.  Note	that to	bind the `"' or	`'' keys, quotation marks are neces-
     sary, for example:

	   bind-key '"'	split-window
	   bind-key "'"	new-window

     Commands related to key bindings are as follows:

     bind-key [-cnr] [-t key-table] key	command	[arguments]
		   (alias: bind)
	     Bind key key to command.  By default (without -t) the primary key
	     bindings are modified (those normally activated with the prefix
	     key); in this case, if -n is specified, it	is not necessary to
	     use the prefix key, command is bound to key alone.	 The -r	flag
	     indicates this key	may repeat, see	the repeat-time	option.

	     If	-t is present, key is bound in key-table: the binding for com-
	     mand mode with -c or for normal mode without.  To view the	de-
	     fault bindings and	possible commands, see the list-keys command.

     list-keys [-t key-table]
		   (alias: lsk)
	     List all key bindings.  Without -t	the primary key	bindings -
	     those executed when preceded by the prefix	key - are printed.
	     Keys bound	without	the prefix key (see bind-key -n) are marked
	     with `(no prefix)'.

	     With -t, the key bindings in key-table are	listed;	this may be
	     one of: vi-edit, emacs-edit, vi-choice, emacs-choice, vi-copy or

     send-keys [-t target-pane]	key ...
		   (alias: send)
	     Send a key	or keys	to a window.  Each argument key	is the name of
	     the key (such as `C-a' or `npage' ) to send; if the string	is not
	     recognised	as a key, it is	sent as	a series of characters.	 All
	     arguments are sent	sequentially from first	to last.

     send-prefix [-t target-pane]
	     Send the prefix key to a window as	if it was pressed.  If multi-
	     ple prefix	keys are configured, only the first is sent.

     unbind-key	[-acn] [-t key-table] key
		   (alias: unbind)
	     Unbind the	command	bound to key.  Without -t the primary key
	     bindings are modified; in this case, if -n	is specified, the com-
	     mand bound	to key without a prefix	(if any) is removed.  If -a is
	     present, all key bindings are removed.

	     If	-t is present, key in key-table	is unbound: the	binding	for
	     command mode with -c or for normal	mode without.

     The appearance and	behaviour of tmux may be modified by changing the
     value of various options.	There are three	types of option: server
     options, session options and window options.

     The tmux server has a set of global options which do not apply to any
     particular	window or session.  These are altered with the set-option -s
     command, or displayed with	the show-options -s command.

     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 set-option
     command and may be	listed with the	show-options command.  The available
     server and	session	options	are listed under the set-option	command.

     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	inher-
     ited.  Window options are altered with the	set-window-option command and
     can be listed with	the show-window-options	command.  All window options
     are documented with the set-window-option command.

     Commands which set	options	are as follows:

     set-option	[-agsuw] [-t target-session | target-window] option value
		   (alias: set)
	     Set a window option with -w (equivalent to	the set-window-option
	     command), a server	option with -s,	otherwise a session option.

	     If	-g is specified, the global session or window option is	set.
	     With -a, and if the option	expects	a string, value	is appended to
	     the existing setting.  The	-u flag	unsets an option, so a session
	     inherits the option from the global options.  It is not possible
	     to	unset a	global option.

	     Available window options are listed under set-window-option.

	     Available server options are:

	     buffer-limit number
		     Set the number of buffers;	as new buffers are added to
		     the top of	the stack, old ones are	removed	from the bot-
		     tom if necessary to maintain this maximum length.

	     set-clipboard [on | off]
		     Attempt to	set the	terminal clipboard content using the
		     \e]52;...\007 xterm(1) escape sequences.  This option is
		     on	by default if there is an Ms entry in the terminfo(5)
		     description for the client	terminal.  Note	that this fea-
		     ture needs	to be enabled in xterm(1) by setting the re-

			   disallowedWindowOps:	20,21,SetXprop

		     Or	changing this property from the	xterm(1) interactive
		     menu when required.

	     escape-time time
		     Set the time in milliseconds for which tmux waits after
		     an	escape is input	to determine if	it is part of a	func-
		     tion or meta key sequences.  The default is 500 millisec-

	     exit-unattached [on | off]
		     If	enabled, the server will exit when there are no	at-
		     tached clients.

	     quiet [on | off]
		     Enable or disable the display of various informational
		     messages (see also	the -q command line flag).

	     Available session options are:

	     base-index	index
		     Set the base index	from which an unused index should be
		     searched when a new window	is created.  The default is

	     bell-action [any |	none | current]
		     Set action	on window bell.	 any means a bell in any win-
		     dow linked	to a session causes a bell in the current win-
		     dow of that session, none means all bells are ignored and
		     current means only	bell in	windows	other than the current
		     window are	ignored.

	     bell-on-alert [on | off]
		     If	on, ring the terminal bell when	an activity, content
		     or	silence	alert occurs.

	     default-command shell-command
		     Set the command used for new windows (if not specified
		     when the window is	created) to shell-command, which may
		     be	any sh(1) command.  The	default	is an empty string,
		     which instructs tmux to create a login shell using	the
		     value of the default-shell	option.

	     default-path path
		     Set the default working directory for processes created
		     from keys,	or interactively from the prompt.  The default
		     is	empty, which means to use the working directory	of the
		     shell from	which the server was started if	it is avail-
		     able or the user's	home if	not.

	     default-shell path
		     Specify the default shell.	 This is used as the login
		     shell for new windows when	the default-command option is
		     set to empty, and must be the full	path of	the exe-
		     cutable.  When started tmux tries to set a	default	value
		     from the first suitable of	the SHELL environment vari-
		     able, the shell returned by getpwuid(3), or /bin/sh.
		     This option should	be configured when tmux	is used	as a
		     login shell.

	     default-terminal terminal
		     Set the default terminal for new windows created in this
		     session - the default value of the	TERM environment vari-
		     able.  For	tmux to	work correctly,	this must be set to
		     `screen' or a derivative of it.

	     destroy-unattached	[on | off]
		     If	enabled	and the	session	is no longer attached to any
		     clients, it is destroyed.

	     detach-on-destroy [on | off]
		     If	on (the	default), the client is	detached when the ses-
		     sion it is	attached to is destroyed.  If off, the client
		     is	switched to the	most recently active of	the remaining

	     display-panes-active-colour colour
		     Set the colour used by the	display-panes command to show
		     the indicator for the active pane.

	     display-panes-colour colour
		     Set the colour used by the	display-panes command to show
		     the indicators for	inactive panes.

	     display-panes-time	time
		     Set the time in milliseconds for which the	indicators
		     shown by the display-panes	command	appear.

	     display-time time
		     Set the amount of time for	which status line messages and
		     other on-screen indicators	are displayed.	time is	in

	     history-limit lines
		     Set the maximum number of lines held in window history.
		     This setting applies only to new windows -	existing win-
		     dow histories are not resized and retain the limit	at the
		     point they	were created.

	     lock-after-time number
		     Lock the session (like the	lock-session command) after
		     number seconds of inactivity, or the entire server	(all
		     sessions) if the lock-server option is set.  The default
		     is	not to lock (set to 0).

	     lock-command shell-command
		     Command to	run when locking each client.  The default is
		     to	run lock(1) with -np.

	     lock-server [on | off]
		     If	this option is on (the default), instead of each ses-
		     sion locking individually as each has been	idle for
		     lock-after-time, the entire server	will lock after	all
		     sessions would have locked.  This has no effect as	a ses-
		     sion option; it must be set as a global option.

	     message-attr attributes
		     Set status	line message attributes, where attributes is
		     either none or a comma-delimited list of one or more of:
		     bright (or	bold), dim, underscore,	blink, reverse,
		     hidden, or	italics.

	     message-bg	colour
		     Set status	line message background	colour,	where colour
		     is	one of:	black, red, green, yellow, blue, magenta,
		     cyan, white, colour0 to colour255 from the	256-colour
		     set, default, or a	hexadecimal RGB	string such as
		     `#ffffff',	which chooses the closest match	from the de-
		     fault 256-colour set.

	     message-fg	colour
		     Set status	line message foreground	colour.

	     message-limit number
		     Set the number of error or	information messages to	save
		     in	the message log	for each client.  The default is 20.

	     mouse-resize-pane [on | off]
		     If	on, tmux captures the mouse and	allows panes to	be re-
		     sized by dragging on their	borders.

	     mouse-select-pane [on | off]
		     If	on, tmux captures the mouse and	when a window is split
		     into multiple panes the mouse may be used to select the
		     current pane.  The	mouse click is also passed through to
		     the application as	normal.

	     mouse-select-window [on | off]
		     If	on, clicking the mouse on a window name	in the status
		     line will select that window.

	     pane-active-border-bg colour

	     pane-active-border-fg colour
		     Set the pane border colour	for the	currently active pane.

	     pane-border-bg colour

	     pane-border-fg colour
		     Set the pane border colour	for panes aside	from the ac-
		     tive pane.

	     prefix keys
		     Set the keys accepted as a	prefix key.  keys is a comma-
		     separated list of key names, each of which	individually
		     behave as the prefix key.

	     repeat-time time
		     Allow multiple commands to	be entered without pressing
		     the prefix-key again in the specified time	milliseconds
		     (the default is 500).  Whether a key repeats may be set
		     when it is	bound using the	-r flag	to bind-key.  Repeat
		     is	enabled	for the	default	keys bound to the resize-pane

	     mouse-utf8	[on | off]
		     If	enabled, request mouse input as	UTF-8 on UTF-8 termi-

	     set-remain-on-exit	[on | off]
		     Set the remain-on-exit window option for any windows
		     first created in this session.  When this option is true,
		     windows in	which the running program has exited do	not
		     close, instead remaining open but inactivate.  Use	the
		     respawn-window command to reactivate such a window, or
		     the kill-window command to	destroy	it.

	     set-titles	[on | off]
		     Attempt to	set the	window title using the \e]2;...\007
		     xterm code	if the terminal	appears	to be an xterm.	 This
		     option is off by default.	Note that elinks will only at-
		     tempt to set the window title if the STY environment
		     variable is set.

	     set-titles-string string
		     String used to set	the window title if set-titles is on.
		     Character sequences are replaced as for the status-left

	     status [on	| off]
		     Show or hide the status line.

	     status-attr attributes
		     Set status	line attributes.

	     status-bg colour
		     Set status	line background	colour.

	     status-fg colour
		     Set status	line foreground	colour.

	     status-interval interval
		     Update the	status bar every interval seconds.  By de-
		     fault, updates will occur every 15	seconds.  A setting of
		     zero disables redrawing at	interval.

	     status-justify [left | centre | right]
		     Set the position of the window list component of the sta-
		     tus line: left, centre or right justified.

	     status-keys [vi | emacs]
		     Use vi or emacs-style key bindings	in the status line,
		     for example at the	command	prompt.	 The default is	emacs,
		     unless the	VISUAL or EDITOR environment variables are set
		     and contain the string `vi'.

	     status-left string
		     Display string to the left	of the status bar.  string
		     will be passed through strftime(3)	before being used.  By
		     default, the session name is shown.  string may contain
		     any of the	following special character sequences:

			   Character pair    Replaced with
			   #(shell-command)  First line	of the command's
			   #[attributes]     Colour or attribute change
			   #H		     Hostname of local host
			   #h		     Hostname of local host without
							      the domain name
			   #F		     Current window flag
			   #I		     Current window index
			   #P		     Current pane index
			   #S		     Session name
			   #T		     Current window title
			   #W		     Current window name
			   ##		     A literal `#'

		     The #(shell-command) form executes	`shell-command'	and
		     inserts the first line of its output.  Note that shell
		     commands are only executed	once at	the interval specified
		     by	the status-interval option: if the status line is re-
		     drawn in the meantime, the	previous result	is used.
		     Shell commands are	executed with the tmux global environ-
		     ment set (see the ENVIRONMENT section).

		     The window	title (#T) is the title	set by the program
		     running within the	window using the OSC title setting se-
		     quence, for example:

			   $ printf '\033]2;My Title\033\\'

		     When a window is first created, its title is the host-

		     #[attributes] allows a comma-separated list of attributes
		     to	be specified, these may	be `fg=colour' to set the
		     foreground	colour,	`bg=colour' to set the background
		     colour, the name of one of	the attributes (listed under
		     the message-attr option) to turn an attribute on, or an
		     attribute prefixed	with `no' to turn one off, for example
		     nobright.	Examples are:

			   #(sysctl vm.loadavg)
			   #[fg=yellow,bold]#(apm -l)%%#[default] [#S]

		     Where appropriate,	special	character sequences may	be
		     prefixed with a number to specify the maximum length, for
		     example `#24T'.

		     By	default, UTF-8 in string is not	interpreted, to	enable
		     UTF-8, use	the status-utf8	option.

	     status-left-attr attributes
		     Set the attribute of the left part	of the status line.

	     status-left-bg colour
		     Set the background	colour of the left part	of the status

	     status-left-fg colour
		     Set the foreground	colour of the left part	of the status

	     status-left-length	length
		     Set the maximum length of the left	component of the sta-
		     tus bar.  The default is 10.

	     status-right string
		     Display string to the right of the	status bar.  By	de-
		     fault, the	current	window title in	double quotes, the
		     date and the time are shown.  As with status-left,	string
		     will be passed to strftime(3), character pairs are	re-
		     placed, and UTF-8 is dependent on the status-utf8 option.

	     status-right-attr attributes
		     Set the attribute of the right part of the	status line.

	     status-right-bg colour
		     Set the background	colour of the right part of the	status

	     status-right-fg colour
		     Set the foreground	colour of the right part of the	status

	     status-right-length length
		     Set the maximum length of the right component of the sta-
		     tus bar.  The default is 40.

	     status-utf8 [on | off]
		     Instruct tmux to treat top-bit-set	characters in the
		     status-left and status-right strings as UTF-8; notably,
		     this is important for wide	characters.  This option de-
		     faults to off.

	     terminal-overrides	string
		     Contains a	list of	entries	which override terminal	de-
		     scriptions	read using terminfo(5).	 string	is a comma-
		     separated list of items each a colon-separated string
		     made up of	a terminal type	pattern	(matched using
		     fnmatch(3)) and a set of name=value entries.

		     For example, to set the `clear' terminfo(5) entry to
		     `\e[H\e[2J' for all terminal types	and the	`dch1' entry
		     to	`\e[P' for the `rxvt' terminal type, the option	could
		     be	set to the string:


		     The terminal entry	value is passed	through	strunvis(3)
		     before interpretation.  The default value forcibly	cor-
		     rects the `colors'	entry for terminals which support 88
		     or	256 colours:


	     update-environment	variables
		     Set a space-separated string containing a list of envi-
		     ronment variables to be copied into the session environ-
		     ment when a new session is	created	or an existing session
		     is	attached.  Any variables that do not exist in the
		     source environment	are set	to be removed from the session
		     environment (as if	-r was given to	the set-environment
		     command).	The default is "DISPLAY	SSH_ASKPASS

	     visual-activity [on | off]
		     If	on, display a status line message when activity	occurs
		     in	a window for which the monitor-activity	window option
		     is	enabled.

	     visual-bell [on | off]
		     If	this option is on, a message is	shown on a bell	in-
		     stead of it being passed through to the terminal (which
		     normally makes a sound).  Also see	the bell-action	op-

	     visual-content [on	| off]
		     Like visual-activity, display a message when content is
		     present in	a window for which the monitor-content window
		     option is enabled.

	     visual-silence [on	| off]
		     If	monitor-silence	is enabled, prints a message after the
		     interval has expired on a given window.

     set-window-option [-agu] [-t target-window] option	value
		   (alias: setw)
	     Set a window option.  The -a, -g and -u flags work	similarly to
	     the set-option command.

	     Supported window options are:

	     aggressive-resize [on | off]
		     Aggressively resize the chosen window.  This means	that
		     tmux will resize the window to the	size of	the smallest
		     session for which it is the current window, rather	than
		     the smallest session to which it is attached.  The	window
		     may resize	when the current window	is changed on another
		     sessions; this option is good for full-screen programs
		     which support SIGWINCH and	poor for interactive programs
		     such as shells.

	     alternate-screen [on | off]
		     This option configures whether programs running inside
		     tmux may use the terminal alternate screen	feature, which
		     allows the	smcup and rmcup	terminfo(5) capabilities.  The
		     alternate screen feature preserves	the contents of	the
		     window when an interactive	application starts and re-
		     stores it on exit,	so that	any output visible before the
		     application starts	reappears unchanged after it exits.
		     The default is on.

	     automatic-rename [on | off]
		     Control automatic window renaming.	 When this setting is
		     enabled, tmux will	attempt	- on supported platforms - to
		     rename the	window to reflect the command currently	run-
		     ning in it.  This flag is automatically disabled for an
		     individual	window when a name is specified	at creation
		     with new-window or	new-session, or	later with
		     rename-window.  It	may be switched	off globally with:

			   set-window-option -g	automatic-rename off

	     clock-mode-colour colour
		     Set clock colour.

	     clock-mode-style [12 | 24]
		     Set clock hour format.

	     force-height height
	     force-width width
		     Prevent tmux from resizing	a window to greater than width
		     or	height.	 A value of zero restores the default unlim-
		     ited setting.

	     main-pane-height height
	     main-pane-width width
		     Set the width or height of	the main (left or top) pane in
		     the main-horizontal or main-vertical layouts.

	     mode-attr attributes
		     Set window	modes attributes.

	     mode-bg colour
		     Set window	modes background colour.

	     mode-fg colour
		     Set window	modes foreground colour.

	     mode-keys [vi | emacs]
		     Use vi or emacs-style key bindings	in copy	and choice
		     modes.  As	with the status-keys option, the default is
		     emacs, unless VISUAL or EDITOR contains `vi'.

	     mode-mouse	[on | off]
		     Mouse state in modes.  If on, the mouse may be used to
		     enter copy	mode and copy a	selection by dragging, to en-
		     ter copy mode and scroll with the mouse wheel, or to se-
		     lect an option in choice mode.

	     monitor-activity [on | off]
		     Monitor for activity in the window.  Windows with activ-
		     ity are highlighted in the	status line.

	     monitor-content match-string
		     Monitor content in	the window.  When fnmatch(3) pattern
		     match-string appears in the window, it is highlighted in
		     the status	line.

	     monitor-silence [interval]
		     Monitor for silence (no activity) in the window within
		     interval seconds.	Windows	that have been silent for the
		     interval are highlighted in the status line.  An interval
		     of	zero disables the monitoring.

	     other-pane-height height
		     Set the height of the other panes (not the	main pane) in
		     the main-horizontal layout.  If this option is set	to 0
		     (the default), it will have no effect.  If	both the
		     main-pane-height and other-pane-height options are	set,
		     the main pane will	grow taller to make the	other panes
		     the specified height, but will never shrink to do so.

	     other-pane-width width
		     Like other-pane-height, but set the width of other	panes
		     in	the main-vertical layout.

	     remain-on-exit [on	| off]
		     A window with this	flag set is not	destroyed when the
		     program running in	it exits.  The window may be reacti-
		     vated with	the respawn-window command.

	     synchronize-panes [on | off]
		     Duplicate input to	any pane to all	other panes in the
		     same window (only for panes that are not in any special

	     utf8 [on |	off]
		     Instructs tmux to expect UTF-8 sequences to appear	in
		     this window.

	     window-status-attr	attributes
		     Set status	line attributes	for a single window.

	     window-status-bg colour
		     Set status	line background	colour for a single window.

	     window-status-fg colour
		     Set status	line foreground	colour for a single window.

	     window-status-format string
		     Set the format in which the window	is displayed in	the
		     status line window	list.  See the status-left option for
		     details of	special	character sequences available.	The
		     default is	`#I:#W#F'.

	     window-status-alert-attr attributes
		     Set status	line attributes	for windows which have an
		     alert (bell, activity or content).

	     window-status-alert-bg colour
		     Set status	line background	colour for windows with	an

	     window-status-alert-fg colour
		     Set status	line foreground	colour for windows with	an

	     window-status-current-attr	attributes
		     Set status	line attributes	for the	currently active win-

	     window-status-current-bg colour
		     Set status	line background	colour for the currently ac-
		     tive window.

	     window-status-current-fg colour
		     Set status	line foreground	colour for the currently ac-
		     tive window.

	     window-status-current-format string
		     Like window-status-format,	but is the format used when
		     the window	is the current window.

	     word-separators string
		     Sets the window's conception of what characters are con-
		     sidered word separators, for the purposes of the next and
		     previous word commands in copy mode.  The default is
		     ` -_@'.

	     xterm-keys	[on | off]
		     If	this option is set, tmux will generate xterm(1)	-style
		     function key sequences; these have	a number included to
		     indicate modifiers	such as	Shift, Alt or Ctrl.  The de-
		     fault is off.

     show-options [-gsw] [-t target-session | target-window]
		   (alias: show)
	     Show the window options with -w (equivalent to
	     show-window-options), the server options with -s, otherwise the
	     session options for target	session.  Global session or window op-
	     tions are listed if -g is used.

     show-window-options [-g] [-t target-window]
		   (alias: showw)
	     List the window options for target-window,	or the global window
	     options if	-g is used.

     When the server is	started, tmux copies the environment into the global
     environment; in addition, each session has	a 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.

     The update-environment session option may be used to update the session
     environment from the client when a	new session is created or an old reat-
     tached.  tmux also	initialises the	TMUX variable with some	internal in-
     formation to allow	commands to be executed	from inside, and the TERM
     variable with the correct terminal	setting	of `screen'.

     Commands to alter and view	the environment	are:

     set-environment [-gru] [-t	target-session]	name [value]
		   (alias: setenv)
	     Set or unset an environment variable.  If -g is used, the change
	     is	made in	the global environment;	otherwise, it is applied to
	     the session environment for target-session.  The -u flag unsets a
	     variable.	-r indicates the variable is to	be removed from	the
	     environment before	starting a new process.

     show-environment [-g] [-t target-session]
		   (alias: showenv)
	     Display the environment for target-session	or the global environ-
	     ment with -g.  Variables removed from the environment are pre-
	     fixed with	`-'.

     tmux 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 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.

     The status	line is	made of	three parts: configurable left and right sec-
     tions (which may contain dynamic content such as the time or output from
     a shell command, see the status-left, status-left-length, status-right,
     and 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	window-status-format and
     window-status-current-format options.  The	flag is	one of the following
     symbols appended to the window name:

	   Symbol    Meaning
	   *	     Denotes the current window.
	   -	     Marks the last window (previously selected).
	   #	     Window is monitored and activity has been detected.
	   !	     A bell has	occurred in the	window.
	   +	     Window is monitored for content and it has	appeared.
	   ~	     The window	has been silent	for the	monitor-silence

     The # symbol relates to the monitor-activity and +	to the monitor-content
     window options.  The window name is printed in inverted colours if	an
     alert (bell, activity or content) is present.

     The colour	and attributes of the status line may be configured, the en-
     tire status line using the	status-attr, status-fg and status-bg session
     options and individual windows using the window-status-attr,
     window-status-fg and window-status-bg window options.

     The status	line is	automatically refreshed	at interval if it has changed,
     the interval may be controlled with the status-interval session option.

     Commands related to the status line are as	follows:

     command-prompt [-I	inputs]	[-p prompts] [-t target-client]	[template]
	     Open the command prompt in	a client.  This	may be used from in-
	     side tmux to execute commands interactively.

	     If	template is specified, it is used as the command.  If present,
	     -I	is a comma-separated list of the initial text for each prompt.
	     If	-p is given, prompts is	a comma-separated list of prompts
	     which are displayed in order; otherwise a single prompt is	dis-
	     played, constructed from template if it is	present, or `:'	if

	     Both inputs and prompts may contain the special character se-
	     quences supported by the status-left option.

	     Before the	command	is executed, the first occurrence of the
	     string `%%' and all occurrences of	`%1' are replaced by the re-
	     sponse to the first prompt, the second `%%' and all `%2' are re-
	     placed with the response to the second prompt, and	so on for fur-
	     ther prompts.  Up to nine prompt responses	may be replaced	(`%1'
	     to	`%9').

     confirm-before [-p	prompt]	[-t target-client] command
		   (alias: confirm)
	     Ask for confirmation before executing command.  If	-p is given,
	     prompt is the prompt to display; otherwise	a prompt is construc-
	     ted from command.	It may contain the special character sequences
	     supported by the status-left option.

	     This command works	only from inside tmux.

     display-message [-p] [-c target-client] [-t target-pane] [message]
		   (alias: display)
	     Display a message.	 If -p is given, the output is printed to std-
	     out, otherwise it is displayed in the target-client status	line.
	     The format	of message is as for status-left, with the exception
	     that #() are not handled; information is taken from target-pane
	     if	-t is given, otherwise the active pane for the session at-
	     tached to target-client.

     tmux maintains a stack of paste buffers.  Up to the value of the
     buffer-limit option are kept; when	a new buffer is	added, the buffer at
     the bottom	of the stack is	removed.  Buffers may be added using copy-mode
     or	the set-buffer command,	and pasted into	a window using the
     paste-buffer command.

     A configurable history buffer is also maintained for each window.	By de-
     fault, up to 2000 lines are kept; this can	be altered with	the
     history-limit option (see the set-option command above).

     The buffer	commands are as	follows:

     choose-buffer [-t target-window] [template]
	     Put a window into buffer choice mode, where a buffer may be cho-
	     sen interactively from a list.  After a buffer is selected, `%%'
	     is	replaced by the	buffer index in	template and the result	exe-
	     cuted as a	command.  If template is not given, "paste-buffer -b
	     '%%'" is used.  This command works	only from inside tmux.

     clear-history [-t target-pane]
		   (alias: clearhist)
	     Remove and	free the history for the specified pane.

     delete-buffer [-b buffer-index]
		   (alias: deleteb)
	     Delete the	buffer at buffer-index,	or the top buffer if not spec-

		   (alias: lsb)
	     List the global buffers.

     load-buffer [-b buffer-index] path
		   (alias: loadb)
	     Load the contents of the specified	paste buffer from path.

     paste-buffer [-dr]	[-b buffer-index] [-s separator] [-t target-pane]
		   (alias: pasteb)
	     Insert the	contents of a paste buffer into	the specified pane.
	     If	not specified, paste into the current one.  With -d, also
	     delete the	paste buffer from the stack.  When output, any line-
	     feed (LF) characters in the paste buffer are replaced with	a sep-
	     arator, by	default	carriage return	(CR).  A custom	separator may
	     be	specified using	the -s flag.  The -r flag means	to do no re-
	     placement (equivalent to a	separator of LF).

     save-buffer [-a] [-b buffer-index]	path
		   (alias: saveb)
	     Save the contents of the specified	paste buffer to	path.  The -a
	     option appends to rather than overwriting the file.

     set-buffer	[-b buffer-index] data
		   (alias: setb)
	     Set the contents of the specified buffer to data.

     show-buffer [-b buffer-index]
		   (alias: showb)
	     Display the contents of the specified buffer.

     Miscellaneous commands are	as follows:

     clock-mode	[-t target-pane]
	     Display a large clock.

     if-shell shell-command command
		   (alias: if)
	     Execute command if	shell-command returns success.

		   (alias: lock)
	     Lock each client individually by running the command specified by
	     the lock-command option.

     run-shell shell-command
		   (alias: run)
	     Execute shell-command in the background without creating a	win-
	     dow.  After it finishes, any output to stdout is displayed	in
	     copy mode.	 If the	command	doesn't	return success,	the exit sta-
	     tus is also displayed.

		   (alias: info)
	     Show server information and terminal details.

     tmux understands some extensions to terminfo(5):

     Cc, Cr  Set the cursor colour.  The first takes a single string argument
	     and is used to set	the colour; the	second takes no	arguments and
	     restores the default cursor colour.  If set, a sequence such as
	     this may be used to change	the cursor colour from inside tmux:

		   $ printf '\033]12;red\033\\'

     Cs, Csr
	     Change the	cursor style.  If set, a sequence such as this may be
	     used to change the	cursor to an underline:

		   $ printf '\033[4 q'

	     If	Csr is set, it will be used to reset the cursor	style instead
	     of	Cs.

     Ms	     This sequence can be used by tmux to store	the current buffer in
	     the host terminal's selection (clipboard).	 See the set-clipboard
	     option above and the xterm(1) man page.

     ~/.tmux.conf	Default	tmux configuration file.
     /etc/tmux.conf	System-wide configuration file.

     To	create a new tmux session running vi(1):

	   $ tmux new-session vi

     Most commands have	a shorter form,	known as an alias.  For	new-session,
     this is new:

	   $ tmux new vi

     Alternatively, the	shortest unambiguous form of a command is accepted.
     If	there are several options, they	are listed:

	   $ tmux n
	   ambiguous command: n, could be: new-session,	new-window, next-window

     Within an active session, a new window may	be created by typing `C-b c'
     (Ctrl followed by the `b' key followed by the `c' key).

     Windows may be navigated with: `C-b 0' (to	select window 0), `C-b 1' (to
     select window 1), and so on; `C-b n' to select the	next window; and `C-b
     p'	to select the previous window.

     A session may be detached using `C-b d' (or by an external	event such as
     ssh(1) disconnection) and reattached with:

	   $ tmux attach-session

     Typing `C-b ?' lists the current key bindings in the current window; up
     and down may be used to navigate the list or `q' to exit from it.

     Commands to be run	when the tmux server is	started	may be placed in the
     ~/.tmux.conf configuration	file.  Common examples include:

     Changing the default prefix key:

	   set-option -g prefix	C-a
	   unbind-key C-b
	   bind-key C-a	send-prefix

     Turning the status	line off, or changing its colour:

	   set-option -g status	off
	   set-option -g status-bg blue

     Setting other options, such as the	default	command, or locking after 30
     minutes of	inactivity:

	   set-option -g default-command "exec /bin/ksh"
	   set-option -g lock-after-time 1800

     Creating new key bindings:

	   bind-key b set-option status
	   bind-key / command-prompt "split-window 'exec man %%'"
	   bind-key S command-prompt "new-window -n %1 'ssh %1'"
