default-path isn't empty, it is used. Otherwise: 1) If tmux neww is run from the command line, the working directory of the client is used. 2) Otherwise use some platform specific code to retrieve the current working directory of the process in the active pane. 3) If that fails, the directory where the session was created is used.

.Sh DESCRIPTION
|
|
.Nm
|
|
is a terminal multiplexer:
|
|
it enables a number of terminals to be created, accessed, and
|
|
controlled from a single screen.
|
|
.Nm
|
|
may be detached from a screen
|
|
and continue running in the background,
|
|
then later reattached.
|
|
.Pp
|
|
When
|
|
.Nm
|
|
is started it creates a new
|
|
.Em session
|
|
with a single
|
|
.Em window
|
|
and displays it on screen.
|
|
A status line at the bottom of the screen
|
|
shows information on the current session
|
|
and is used to enter interactive commands.
|
|
.Pp
|
|
A session is a single collection of
|
|
.Em pseudo terminals
|
|
under the management of
|
|
.Nm .
|
|
Each session has one or more
|
|
windows linked to it.
|
|
A window occupies the entire screen
|
|
and may be split into rectangular panes,
|
|
each of which is a separate pseudo terminal
|
|
(the
|
|
.Xr pty 4
|
|
manual page documents the technical details of pseudo terminals).
|
|
Any number of
|
|
.Nm
|
|
instances may connect to the same session,
|
|
and any number of windows may be present in the same session.
|
|
Once all sessions are killed,
|
|
.Nm
|
|
exits.
|
|
.Pp
|
|
Each session is persistent and will survive accidental disconnection
|
|
(such as
|
|
.Xr ssh 1
|
|
connection timeout) or intentional detaching (with the
|
|
.Ql C-b d
|
|
key strokes).
|
|
.Nm
|
|
may be reattached using:
|
|
.Pp
|
|
.Dl $ tmux attach
|
|
.Pp
|
|
In
|
|
.Nm ,
|
|
a session is displayed on screen by a
|
|
.Em client
|
|
and all sessions are managed by a single
|
|
.Em server .
|
|
The server and each client are separate processes which communicate through a
|
|
socket in
|
|
.Pa /tmp .
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width "XXXXXXXXXXXX"
|
|
.It Fl 2
|
|
Force
|
|
.Nm
|
|
to assume the terminal supports 256 colours.
|
|
.It Fl 8
|
|
Like
|
|
.Fl 2 ,
|
|
but indicates that the terminal supports 88 colours.
|
|
.It Fl 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 .
|
|
The configuration file is a set of
|
|
.Nm
|
|
commands which are executed in sequence when the server is first started.
|
|
.Pp
|
|
If a command in the configuration file fails,
|
|
.Nm
|
|
will report an error and exit without executing further commands.
|
|
.It Fl L Ar socket-name
|
|
.Nm
|
|
stores the server socket in a directory under
|
|
.Pa /tmp
|
|
(or
|
|
.Ev TMPDIR
|
|
if set);
|
|
the default socket is named
|
|
.Em default .
|
|
This option allows a different socket name to be specified, allowing several
|
|
independent
|
|
.Nm
|
|
servers to be run.
|
|
Unlike
|
|
.Fl S
|
|
a full path is not necessary: the sockets are all created in the same
|
|
directory.
|
|
.Pp
|
|
If the socket is accidentally removed, the
|
|
.Dv SIGUSR1
|
|
signal may be sent to the
|
|
.Nm
|
|
server process to recreate it.
|
|
.It Fl 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 q
|
|
Set the
|
|
.Ic quiet
|
|
server option to prevent the server sending various informational messages.
|
|
.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
|
|
.Nm
|
|
attempts to guess if the terminal is likely to support UTF-8 by checking the
|
|
first of the
|
|
.Ev LC_ALL ,
|
|
.Ev LC_CTYPE
|
|
and
|
|
.Ev LANG
|
|
environment variables to be set for the string "UTF-8".
|
|
This is not always correct: the
|
|
.Fl u
|
|
flag explicitly informs
|
|
.Nm
|
|
that UTF-8 is supported.
|
|
.Pp
|
|
If the server is started from a client passed
|
|
.Fl u
|
|
or where UTF-8 is detected, the
|
|
.Ic utf8
|
|
and
|
|
.Ic status-utf8
|
|
options are enabled in the global window and session options respectively.
|
|
.It Fl v
|
|
Request verbose logging.
|
|
This option may be specified multiple times for increasing verbosity.
|
|
Log messages will be saved into
|
|
.Pa tmux-client-PID.log
|
|
and
|
|
.Pa tmux-server-PID.log
|
|
files in the current directory, where
|
|
.Em PID
|
|
is the PID of the server or client process.
|
|
.It Fl V
|
|
Report the
|
|
.Nm
|
|
version.
|
|
.It Ar command Op Ar flags
|
|
This specifies one of a set of commands used to control
|
|
.Nm ,
|
|
as described in the following sections.
|
|
If no commands are specified, the
|
|
.Ic new-session
|
|
command is assumed.
|
|
.El
|
|
.Sh KEY BINDINGS

|
.Ic bind-key
|
|
and
|
|
.Ic unbind-key
|
|
commands.
|
|
.Sh COMMANDS
|
|
This section contains a list of the commands supported by
|
|
.Nm .
|
|
Most commands accept the optional
|
|
.Fl t
|
|
argument with one of
|
|
.Ar target-client ,
|
|
.Ar target-session
|
|
.Ar target-window ,
|
|
or
|
|
.Ar target-pane .
|
|
These specify the client, session, window or pane which a command should affect.
|
|
.Ar target-client
|
|
is the name of the
|
|
.Xr pty 4
|
|
file to which the client is connected, for example either of
|
|
.Pa /dev/ttyp1
|
|
or
|
|
.Pa ttyp1
|
|
for the client attached to
|
|
.Pa /dev/ttyp1 .
|
|
If no client is specified, the current client is chosen, if possible, or an
|
|
error is reported.
|
|
Clients may be listed with the
|
|
.Ic list-clients
|
|
command.
|
|
.Pp
|
|
.Ar target-session
|
|
is either the name of a session (as listed by the
|
|
.Ic list-sessions
|
|
command) or the name of a client with the same syntax as
|
|
.Ar target-client ,
|
|
in which case the session attached to the client is used.
|
|
When looking for the session name,
|
|
.Nm
|
|
initially searches for an exact match; if none is found, the session names
|
|
are checked for any for which
|
|
.Ar target-session
|
|
is a prefix or for which it matches as an
|
|
.Xr fnmatch 3
|
|
pattern.
|
|
If a single match is found, it is used as the target session; multiple matches
|
|
produce an error.
|
|
If a session is omitted, the current session is used if available; if no
|
|
current session is available, the most recently used is chosen.
|
|
.Pp
|
|
.Ar target-window
|
|
specifies a window in the form
|
|
.Em session Ns \&: Ns Em window .
|
|
.Em session
|
|
follows the same rules as for
|
|
.Ar target-session ,
|
|
and
|
|
.Em window
|
|
is looked for in order: as a window index, for example mysession:1; as an exact
|
|
window name, such as mysession:mywindow; then as an
|
|
.Xr fnmatch 3
|
|
pattern or the start of a window name, such as mysession:mywin* or
|
|
mysession:mywin.
|
|
An empty window name specifies the next unused index if appropriate (for
|
|
example the
|
|
.Ic new-window
|
|
and
|
|
.Ic link-window
|
|
commands)
|
|
otherwise the current window in
|
|
.Em session
|
|
is chosen.
|
|
The special character
|
|
.Ql \&!
|
|
uses the last (previously current) window, or
|
|
.Ql +
|
|
and
|
|
.Ql -
|
|
are the next window or the previous window by number.
|
|
When the argument does not contain a colon,
|
|
.Nm
|
|
first attempts to parse it as window; if that fails, an attempt is made to
|
|
match a session.
|
|
.Pp
|
|
.Ar target-pane
|
|
takes a similar form to
|
|
.Ar target-window
|
|
but with the optional addition of a period followed by a pane index, for
|
|
example: mysession:mywindow.1.
|
|
If the pane index is omitted, the currently active pane in the specified
|
|
window is used.
|
|
If neither a colon nor period appears,
|
|
.Nm
|
|
first attempts to use the argument as a pane index; if that fails, it is looked
|
|
up as for
|
|
.Ar target-window .
|
|
A
|
|
.Ql +
|
|
or
|
|
.Ql -
|
|
indicate the next or previous pane index, respectively.
|
|
One of the strings
|
|
.Em top ,
|
|
.Em bottom ,
|
|
.Em left ,
|
|
.Em right ,
|
|
.Em top-left ,
|
|
.Em top-right ,
|
|
.Em bottom-left
|
|
or
|
|
.Em bottom-right
|
|
may be used instead of a pane index.
|
|
.Pp
|
|
The special characters
|
|
.Ql +
|
|
and
|
|
.Ql -
|
|
may be followed by an offset, for example:
|
|
.Bd -literal -offset indent
|
|
select-window -t:+2
|
|
.Ed
|
|
.Pp
|
|
When dealing with a session that doesn't contain sequential window indexes,
|
|
they will be correctly skipped.
|
|
.Pp
|
|
.Nm
|
|
also gives each pane created in a server an identifier consisting of a
|
|
.Ql %
|
|
and a number, starting from zero.
|
|
A pane's identifier is unique for the life of the
|
|
.Nm
|
|
server and is passed to the child process of the pane in the
|
|
.Ev TMUX_PANE
|
|
environment variable.
|
|
It may be used alone to target a pane or the window containing it.
|
|
.Pp
|
|
.Ar shell-command
|
|
arguments are
|
|
.Xr sh 1
|
|
commands.
|
|
These must be passed as a single item, which typically means quoting them, for
|
|
example:
|
|
.Bd -literal -offset indent
|
|
new-window 'vi /etc/passwd'
|
|
.Ed
|
|
.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-window-option force-width 81
|
|
.Ed
|
|
.Pp
|
|
Or if using
|
|
.Xr sh 1 :
|
|
.Bd -literal -offset indent
|
|
$ tmux bind-key F1 set-window-option force-width 81
|
|
.Ed
|
|
.Pp
|
|
Multiple commands may be specified together as part of a
|
|
.Em command sequence .
|
|
Each command should be separated by spaces and a semicolon;
|
|
commands are executed sequentially from left to right and
|
|
lines ending with a backslash continue on to the next line.
|
|
A literal semicolon may be included by escaping it with a backslash (for
|
|
example, when specifying a command sequence to
|
|
.Ic bind-key ) .
|
|
.Pp
|
|
Example
|
|
.Nm
|
|
commands include:
|
|
.Bd -literal -offset indent
|
|
refresh-client -t/dev/ttyp2
|
|
|
|
rename-session -tfirst newname
|
|
|
|
set-window-option -t:0 monitor-activity on
|
|
|
|
new-window ; split-window -d
|
|
|
|
bind-key R source-file ~/.tmux.conf \e; \e
|
|
display-message "source-file done"
|
|
.Ed
|
|
.Pp
|
|
Or from
|
|
.Xr sh 1 :
|
|
.Bd -literal -offset indent
|
|
$ tmux kill-window -t :1
|
|
|
|
$ tmux new-window \e; split-window -d
|
|
|
|
$ tmux new-session -d 'vi /etc/passwd' \e; split-window -d \e; attach

.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
|
|
.It Xo Ic attach-session
|
|
.Op Fl dr
|
|
.Op Fl t Ar target-session
|
|
.Xc
|
|
.D1 (alias: Ic attach )
|
|
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
|

.Sh WINDOWS AND PANES
|
|
A
|
|
.Nm
|
|
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
|
|
.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
|
|
The keys available depend on whether emacs or vi mode is selected
|
|
(see the
|
|
.Ic mode-keys
|
|
option).
|
|
The following keys are supported as appropriate for the mode:

.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.
|
|
For example, to move the cursor forward by ten words, use
|
|
.Ql M-1 0 M-f
|
|
in emacs mode, and
|
|
.Ql 10w
|
|
in vi.
|
|
.Pp
|
|
When copying the selection, the repeat count indicates the buffer index to
|
|
replace, if used.
|
|
.Pp
|
|
Mode key bindings are defined in a set of named tables:
|
|
.Em vi-edit
|
|
and
|
|
.Em emacs-edit
|
|
for keys used when line editing at the command prompt;
|
|
.Em vi-choice
|
|
and
|
|
.Em emacs-choice
|
|
for keys used when choosing from lists (such as produced by the
|
|
.Ic choose-window
|
|
command); and
|
|
.Em vi-copy
|
|
and
|
|
.Em emacs-copy
|
|
used in copy mode.
|
|
The tables may be viewed with the
|
|
.Ic list-keys
|
|
command and keys modified or removed with
|
|
.Ic bind-key
|
|
and
|
|
.Ic unbind-key .
|
|
.Pp
|
|
The paste buffer key pastes the first line from the top paste buffer on the
|
|
stack.
|
|
.Pp
|
|
The synopsis for the
|
|
.Ic copy-mode
|
|
command is:

|
|
.It Xo Ic copy-mode
|
|
.Op Fl u
|
|
.Op Fl t Ar target-pane

|
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.

.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 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
|

|
By default (without
|
|
.Fl t )
|
|
the primary key bindings are modified (those normally activated with the prefix
|
|
key); in this case, if
|
|
.Fl n

|
|
alone.
|
|
The

.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
|
|
Commands which set options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Xo Ic set-option
|
|
.Op Fl agsuw
|
|
.Op Fl t Ar target-session | Ar target-window

Set a window option with

.Ic set-window-option
|
|
command),
|
|
a server option with
|
|
.Fl s ,
|
|
otherwise a session option.
|
|
.Pp
|
|
If
|
|
.Fl g
|
|
is specified, the global session or window option is set.
|
|
With
|
|
.Fl a ,
|
|
and if the option expects a string,
|
|
.Ar value
|
|
is appended to the existing setting.
|
|
The
|
|
.Fl u
|
|
flag unsets an option, so a session inherits the option from the global
|
|
options.
|
|
It is not possible to unset a global option.
|
|
.Pp
|

Available window options are listed under
|

|
|
.It Xo Ic aggressive-resize
|
|
.Op Ic on | off

Aggressively resize the chosen window.
|
|
This means that

.Sh 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
|
|

|
.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.
|

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

.Sh BUFFERS
|
|
.Nm
|
|
maintains a stack of
|
|
.Em paste buffers .
|
|
Up to the value of the
|
|
.Ic 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
|
|
.Ic copy-mode
|
|
or the
|
|
.Ic set-buffer
|
|
command, and pasted into a window using the
|
|
.Ic paste-buffer
|
|
command.
|
|
.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).
|
|

|
|
.Op Ar template
|
|
.Xc
|
|
Put a window into buffer choice mode, where a buffer may be chosen
|
|
interactively from a list.
|
|
After a buffer is selected,
|
|
.Ql %%
|
|
is replaced by the buffer index in
|
|
.Ar template
|
|
and the result executed as a command.
|
|
If
|
|
.Ar template
|
|
is not given, "paste-buffer -b '%%'" is used.

|
|
When output, any linefeed (LF) characters in the paste buffer are replaced with
|
|
a separator, by default carriage return (CR).
|
|
A custom separator may be specified using the
|
|
.Fl s
|
|
flag.
|
|
The
|
|
.Fl r
|
|
flag means to do no replacement (equivalent to a separator of LF).

.It Em 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
|
|
.Nm :
|
|
.Bd -literal -offset indent

to change the cursor to an underline:
|
|
.Bd -literal -offset indent
|
|
$ printf '\e033[4 q'
|
