rxvt-unicode (ouR XVT, unicode) - (a VT102 emulator for the X window system)
SYNOPSIS
urxvt [options] [-e command [ args ]]
DESCRIPTION
rxvt-unicode, version 4.7, is a colour vt102 terminal
emulator intended as an xterm(1) replacement for users who do not
require features such as Tektronix 4014 emulation and toolkit-style
configurability. As a result, rxvt-unicode uses much less swap space ---
a significant advantage on a machine serving many X sessions.
FREQUENTLY ASKED QUESTIONS
See urxvt(7) (try
man 7 urxvt ) for a list of frequently
asked questions and answer to them and some common problems.
RXVT-UNICODE VS. RXVT
Unlike the original rxvt, rxvt-unicode stores all text in Unicode
internally. That means it can store and display most scripts in the
world. Being a terminal emulator, however, some things are very difficult,
especially cursive scripts such as arabic, vertically written scripts
like mongolian or scripts requiring extremely complex combining rules,
like tibetan or devenagari. Don't expect pretty output when using these
scripts. Most other scripts, latin, cyrillic, kanji, thai etc. should work
fine, though. A somewhat difficult case are left-to-right scripts, such
as hebrew: rxvt-unicode adopts the view that bidirectional algorithms
belong into the application, not the terminal emulator (too many things ---
such as cursor-movement while editing --- break otherwise), but that might
change.
If you are looking for a terminal that supports more exotic scripts, let
me recommend
mlterm , which is a very userfriendly, lean and clean
terminal emulator. In fact, the reason rxvt-unicode was born was solely
because the author couldn't get
mlterm to use one font for latin1 and
another for japanese.
Therefore another design rationale was the use of multiple fonts to
display characters: The idea of a single unicode font which many other
programs force onto it's users never made sense to me: You should be able
to choose any font for any script freely.
Apart from that, rxvt-unicode is also much better internationalised than
it's predecessor, supports things such as XFT and ISO 14755 that are handy
in i18n-environments, is faster, and has a lot less bugs than the original
rxvt. This all in addition to dozens of other small improvements.
It is still faithfully following the original rxvt idea of being lean
and nice on resources: for example, you can still configure rxvt-unicode
without most of it's features to get a lean binary. It also comes with
a client/daemon pair that lets you open any number of terminal windows
from within a single process, which makes startup time very fast and
drastically reduces memory usage. See urxvtd(1) (daemon) and
urxvtc(1) (client).
It also makes technical information about escape sequences (which have
been extended) easier accessible: see urxvt(7) for technical
reference documentation (escape sequences etc.).
OPTIONS
The urxvt options (mostly a subset of xterm's) are listed
below. In keeping with the smaller-is-better philosophy, options may be
eliminated or default values chosen at compile-time, so options and
defaults listed may not accurately reflect the version installed on
your system. `urxvt -h' gives a list of major compile-time options on
the Options line. Option descriptions may be prefixed with which
compile option each is dependent upon. e.g. `Compile XIM:' requires
XIM on the Options line. Note: `urxvt -help' gives a list of all
command-line options compiled into your version.
Note that urxvt permits the resource name to be used as a
long-option (--/++ option) so the potential command-line options are
far greater than those listed. For example: `urxvt --loginShell --color1
Orange'.
The following options are available:
-help, --help
Print out a message describing available options.
-displaydisplayname
Attempt to open a window on the named X display (-d still
respected). In the absence of this option, the display specified by the
DISPLAY environment variable is used.
-geometrygeom
Window geometry (-g still respected); resource geometry.
Turn on/off inheriting parent window's pixmap. Alternative form is
-tr; resource inheritPixmap.
-fadenumber
Fade the text by the given percentage when focus is lost.
-tintcolour
Tint the transparent background pixmap with the given colour when
transparency is enabled with -tr or -ip. See also the -sh
option that can be used to brighten or darken the image in addition to
tinting it.
-sh
number Darken (0 .. 100) or lighten (-1 .. -100) the transparent
background image in addition to tinting it (i.e. -tint must be
specified, too, e.g.
-tint white ).
-bgcolour
Window background colour; resource background.
-fgcolour
Window foreground colour; resource foreground.
-pixmapfile[;geom]
Compile XPM: Specify XPM file for the background and also optionally
specify its scaling with a geometry string. Note you may need to add
quotes to avoid special shell interpretation of the `;' in the
command-line; resource backgroundPixmap.
-crcolour
The cursor colour; resource cursorColor.
-prcolour
The mouse pointer foreground colour; resource pointerColor.
-pr2colour
The mouse pointer background colour; resource pointerColor2.
-bdcolour
The colour of the border around the text area and between the scrollbar and the text;
resource borderColor.
-fnfontlist
Select the fonts to be used. This is a comma separated list of font names
that are used in turn when trying to display Unicode characters. The
first font defines the cell size for characters; other fonts might be
smaller, but not (in general) larger. A (hopefully) reasonable default
font list is always appended to it. See resource font for more details.
In short, to specify an X11 core font, just specify it's name or prefix it
with
x: . To specify an XFT-font, you need to prefix it with
xft: ,
e.g.:
urxvt -fn "xft:Bitstream Vera Sans Mono:pixelsize=15"
urxvt -fn "9x15bold,xft:Bitstream Vera Sans Mono"
See also the question ``How does rxvt-unicode choose fonts?'' in the FAQ
section of urxvt(7).
-fbfontlist
Compile font-styles: The bold font list to use when bold characters are to
be printed. See resource boldFont for details.
-fifontlist
Compile font-styles: The italic font list to use when bold characters are to
be printed. See resource italicFont for details.
-fbifontlist
Compile font-styles: The bold italic font list to use when bold characters are to
be printed. See resource boldItalicFont for details.
-namename
Specify the application name under which resources are to be obtained,
rather than the default executable file name. Name should not contain
`.' or `*' characters. Also sets the icon and title name.
-ls|+ls
Start as a login-shell/sub-shell; resource loginShell.
-ut|+ut
Compile utmp: Inhibit/enable writing a utmp entry; resource
utmpInhibit.
-vb|+vb
Turn on/off visual bell on receipt of a bell character; resource
visualBell.
-sb|+sb
Turn on/off scrollbar; resource scrollBar.
-si|+si

Display normal (non XTerm/NeXT) scrollbar without/with a trough;
resource scrollBar_floating.
-ptab|+ptab
If enabled (default), ``Horizontal Tab'' characters are being stored as
actual wide characters in the screen buffer, which makes it possible to
select and paste them. Since a horizontal tab is a cursor movement and
not an actual glyph, this can sometimes be visually annoying as the cursor
on a tab character is displayed as a wide cursor; resource pastableTabs.
-bc|+bc
Blink the cursor; resource cursorBlink.
-iconic
Start iconified, if the window manager supports that option.
Alternative form is -ic.
-slnumber

externalBorder.
-bl
Compile frills: Set MWM hints to request a borderless window, i.e.
if honoured by the WM, the rxvt-unicode window will not have window
decorations; resource borderLess.
-lspnumber
Compile linespace: Lines (pixel height) to insert between each row
of the display; resource linespace.
-tntermname
This option specifies the name of the terminal type to be set in the
TERM environment variable. This terminal type must exist in the
termcap(5) database and should have li# and co# entries;
resource termName.
-ecommand [arguments]
Run the command with its command-line arguments in the urxvt
window; also sets the window title and icon name to be the basename of
the program being executed if neither -title (-T) nor -n are
given on the command line. If this option is used, it must be the last
on the command-line. If there is no -e option then the default is to
run the program specified by the SHELL environment variable or,
failing that, sh(1).
-titletext
Window title (-T still respected); the default title is the basename
of the program specified after the -e option, if any, otherwise the
application name; resource title.
-ntext
Icon name; the default name is the basename of the program specified
after the -e option, if any, otherwise the application name;
resource iconName.
The locale to use for opening the IM. You can use an LC_CTYPE of e.g.
de_DE.UTF-8 for normal text processing but ja_JP.EUC-JP for the input
extension to be able to input japanese characters while staying in
another locale.
-insecure
Enable ``insecure'' mode, which currently enables most of the escape
sequences that echo strings. See the resource insecure for more
info.
-modmodifier
Override detection of Meta modifier with specified key: alt,
meta, hyper, super, mod1, mod2, mod3, mod4,
mod5; resource modifier.
No effect on rxvt-unicode. Simply passes through an argument to be made
available in the instance's argument list. Appears in WM_COMMAND in
some window managers.
RESOURCES (available also as long-options)
Note: `urxvt --help' gives a list of all resources (long
options) compiled into your version.
There are two different methods that urxvt can use to get the
Xresource data: using the X libraries (Xrm*-functions) or internal
Xresources reader (~/.Xdefaults). For the first method (ie.
urxvt -h lists XGetDefaults), you can set and change the
resources using X11 tools like xset. Many distribution do also load
settings from the ~/.Xresources file when X starts.
If compiled with internal Xresources support (i.e. urxvt -h
lists .Xdefaults) then urxvt accepts application defaults
set in XAPPLOADDIR/URxvt (compile-time defined: usually
/usr/lib/X11/app-defaults/URxvt) and resources set in
~/.Xdefaults, or ~/.Xresources if ~/.Xdefaults does not exist.
Note that when reading X resources, urxvt recognizes two
class names: XTerm and URxvt. The class name Rxvt allows
resources common to both urxvt and the original rxvt to be
easily configured, while the class name URxvt allows resources
unique to urxvt, notably colours and key-handling, to be
shared between different urxvt configurations. If no
resources are specified, suitable defaults will be used. Command-line
arguments can be used to override resource settings. The following
resources are allowed:
geometry:geom
Create the window with the specified X window geometry [default 80x24];
option -geometry.
background:colour
Use the specified colour as the window's background colour [default
White]; option -bg.
foreground:colour
Use the specified colour as the window's foreground colour [default
Black]; option -fg.
colorn:colour
Use the specified colour for the colour value n, where 0-7
corresponds to low-intensity (normal) colours and 8-15 corresponds to
high-intensity (bold = bright foreground, blink = bright background)
colours. The canonical names are as follows: 0=black, 1=red, 2=green,
3=yellow, 4=blue, 5=magenta, 6=cyan, 7=white, but the actual colour
names used are listed in the COLORSANDGRAPHICS section.
Colours higher than 15 cannot be set using resources (yet), but can be
changed using an escape command (see urxvt(7)).
Colours 16-79 form a standard 4x4x4 colour cube (the same as xterm with
88 colour support). Colours 80-87 are evenly spaces grey steps.
colorBD:colour
colorIT:colour
Use the specified colour to display bold or italic characters when the
foreground colour is the default. If font styles are not available
(Compile styles) and this option is unset, reverse video is used instead.
colorUL:colour
Use the specified colour to display underlined characters when the
foreground colour is the default.
colorRV:colour
Use the specified colour as the background for reverse video
characters.
underlineColor:colour
If set, use the specified colour as the colour for the underline
itself. If unset, use the foreground colour.
cursorColor:colour
Use the specified colour for the cursor. The default is to use the
foreground colour; option -cr.
cursorColor2:colour
Use the specified colour for the colour of the cursor text. For this to
take effect, cursorColor must also be specified. The default is to
use the background colour.
reverseVideo:boolean
True: simulate reverse video by foreground and background colours;
option -rv. False: regular screen colours [default]; option
+rv. See note in COLORSANDGRAPHICS section.
jumpScroll:boolean
True: specify that jump scrolling should be used. When scrolling
quickly, fewer screen updates are performed [default]; option -j.
False: specify that smooth scrolling should be used; option +j.
inheritPixmap:boolean
True: make the background inherit the parent windows' pixmap, giving
artificial transparency. False: do not inherit the parent windows'
pixmap.
fading:number
Fade the text by the given percentage when focus is lost.
tintColor:colour
Tint the transparent background pixmap with the given colour.
shading:number
Darken (0 .. 100) or lighten (-1 .. -100) the transparent background
image in addition to tinting it.
scrollColor:colour
Use the specified colour for the scrollbar [default #B2B2B2].
troughColor:colour
Use the specified colour for the scrollbar's trough area [default
#969696]. Only relevant for normal (non XTerm/NeXT) scrollbar.
borderColor:colour
The colour of the border around the text area and between the scrollbar
and the text.
backgroundPixmap:file[;geom]
Use the specified XPM file (note the `.xpm' extension is optional) for
the background and also optionally specify its scaling with a geometry
string WxH+X+Y, in which ``W'' / ``H'' specify the
horizontal/vertical scale (percent) and ``X'' / ``Y'' locate the image
centre (percent). A scale of 0 displays the image with tiling. A scale
of 1 displays the image without any scaling. A scale of 2 to 9
specifies an integer number of images in that direction. No image will
be magnified beyond 10 times its original size. The maximum permitted
scale is 1000. [default 0x0+50+50]
menu:file[;tag]
Read in the specified menu file (note the `.menu' extension is
optional) and also optionally specify a starting tag to find. See the
reference documentation for details on the syntax for the menuBar.
path:path
Specify the colon-delimited search path for finding files (XPM and
menus), in addition to the paths specified by the RXVTPATH and
PATH environment variables.
font:fontlist
Select the fonts to be used. This is a comma separated list of font
names that are used in turn when trying to display Unicode characters.
The first font defines the cell size for characters; other fonts might
be smaller, but not larger. A reasonable default font list is always
appended to it. option -fn.
Each font can either be a standard X11 core font (XLFD) name, with
optional prefix
x: or a Xft font (Compile xft), prefixed with
xft: .
In addition, each font can be prefixed with additional hints and
specifications enclosed in square brackets (
[] ). The only available
hint currently is
codeset=codeset-name , and this is only used for Xft
fonts.
specifies five fonts to be used. The first one is
9x15bold (actually
the iso8859-1 version of the second font), which is the base font (because
it is named first) and thus defines the character cell grid to be 9 pixels
wide and 15 pixels high.
The second font is just used to add additional unicode characters not in
the base font, likewise the third, which is unfortunately non-bold, but
the bold version of the font does contain less characters, so this is a
useful supplement.
The third font is an Xft font with aliasing turned off, and the characters
are limited to the JIS 0208 codeset (i.e. japanese kanji). The font
contains other characters, but we are not interested in them.
The last font is a useful catch-all font that supplies most of the
remaining unicode characters.
boldFont:fontlist
italicFont:fontlist
boldItalicFont:fontlist
The font list to use for displaying bold, italic or bold
italic characters, respectively.
If specified and non-empty, then the syntax is the same as for the
font-resource, and the given font list will be used as is, which makes
it possible to substitute completely different font styles for bold and
italic.
If unset (the default), a suitable font list will be synthesized by
``morphing'' the normal text font list into the desired shape. If that is
not possible, replacement fonts of the desired shape will be tried.
If set, but empty, then this specific style is disabled and the normal
text font will being used for the given style.
selectstyle:mode
Set mouse selection style to old which is 2.20, oldword which is
xterm style with 2.20 old word selection, or anything else which gives
xterm style selection.
scrollstyle:mode
Set scrollbar style to rxvt, plain, next or xterm. plain is
the author's favourite..
title:string
Set window title string, the default title is the command-line
specified after the -e option, if any, otherwise the application
name; option -title.
iconName:string
Set the name used to label the window's icon or displayed in an icon
manager window, it also sets the window's title unless it is explicitly
set; option -n.

scrollTtyOutput is False); option +sw. False: do not scroll
with scrollback buffer when tty recieves new lines; option -sw.
scrollTtyKeypress:boolean
True: scroll to bottom when a non-special key is pressed. Special keys
are those which are intercepted by rxvt-unicode for special handling and
are not passed onto the shell; option -sk. False: do not scroll to
bottom when a non-special key is pressed; option +sk.
saveLines:number
Save number lines in the scrollback buffer [default 64]. This
resource is limited on most machines to 65535; option -sl.

Mouse pointer background colour.
pointerBlankDelay:number
Specifies number of seconds before blanking the pointer [default 2].
backspacekey:string
The string to send when the backspace key is pressed. If set to DEC
or unset it will send Delete (code 127) or, if shifted, Backspace
(code 8) - which can be reversed with the appropriate DEC private mode
escape sequence.
deletekey:string
The string to send when the delete key (not the keypad delete key) is
pressed. If unset it will send the sequence traditionally associated
with the Execute key.
cutchars:string
The characters used as delimiters for double-click word selection. The
built-in default:

de_DE.UTF-8 for normal text processing but ja_JP.EUC-JP for the input
extension to be able to input japanese characters while staying in
another locale. option -imlocale.
insecure:boolean
Enables ``insecure'' mode. Rxvt-unicode offers some escape sequences that
echo arbitrary strings like the icon name or the locale. This could be
abused if somebody gets 8-bit-clean access to your display, whether
throuh a mail client displaying mail bodies unfiltered or though
write(1). Therefore, these sequences are disabled by default. (Note
that other terminals, including xterm, have these sequences
enabled by default). You can enable them by setting this boolean
resource or specifying -insecure as an option. At the moment, this
enabled display-answer, locale, findfont, icon label and window title
requests as well as dynamic menubar dispatch.
modifier:modifier
Set the key to be interpreted as the Meta key to: alt, meta,
hyper, super, mod1, mod2, mod3, mod4, mod5; option
-mod.
answerbackString:string
Specify the reply rxvt-unicode sends to the shell when an ENQ (control-E)
character is passed through. It may contain escape values as described
in the entry on keysym following.
secondaryScreen:bool
Turn on/off secondary screen (default enabled).
secondaryScroll:bool
Turn on/off secondary screen scroll (default enabled). If the this
option is enabled, scrolls on the secondary screen will change the
scrollback buffer and switching to/from the secondary screen will
instead scroll the screen up.
keysym.sym: string
Associate string with keysym sym (0xFF00 - 0xFFFF). It may
contain escape values (\a: bell, \b: backspace, \e, \E: escape, \n:
newline, \r: return, \t:
tab, \000: octal number) or control characters (^?: delete, ^@: null,
^A ...) and may enclosed with double quotes so that it can start or end
with whitespace. The intervening resource name keysym. cannot be
omitted. This resource is only available when compiled with
KEYSYM_RESOURCE.
THE SCROLLBAR
Lines of text that scroll off the top of the urxvt window
(resource: saveLines) and can be scrolled back using the scrollbar
or by keystrokes. The normal urxvt scrollbar has arrows and
its behaviour is fairly intuitive. The xterm-scrollbar is without
arrows and its behaviour mimics that of xterm
Scroll down with Button1 (xterm-scrollbar) or Shift-Next.
Scroll up with Button3 (xterm-scrollbar) or Shift-Prior.
Continuous scroll with Button2.
MOUSE REPORTING
To temporarily override mouse reporting, for either the scrollbar or
the normal text selection/insertion, hold either the Shift or the Meta
(Alt) key while performing the desired mouse action.
If mouse reporting mode is active, the normal scrollbar actions are
disabled --- on the assumption that we are using a fullscreen
application. Instead, pressing Button1 and Button3 sends ESC[6~
(Next) and ESC[5~ (Prior), respectively. Similarly, clicking on the
up and down arrows sends ESC[A (Up) and ESC[B (Down),
respectively.
TEXT SELECTION AND INSERTION
The behaviour of text selection and insertion mechanism is similar to
xterm(1).
Selection:
Left click at the beginning of the region, drag to the end of the
region and release; Right click to extend the marked region; Left
double-click to select a word; Left triple-click to select the entire
line.
Starting a selection while pressing the Meta key (or Meta+Ctrl keys)
(Compile: frills) will create a rectangular selection instead of a normal
one.
Insertion:
Pressing and releasing the Middle mouse button (or Shift-Insert) in
an urxvt window causes the current text selection to be
inserted as if it had been typed on the keyboard.
CHANGING FONTS
Changing fonts (or font sizes, respectively) via the keypad is not yet
supported in rxvt-unicode. Bug me if you need this.
You can, however, switch fonts at runtime using escape sequences (and
therefore using the menubar), e.g.:
rxvt-unicode will automatically re-apply these fonts to the output so far.
ISO 14755 SUPPORT
ISO 14755 is a standard for entering and viewing unicode characters
and character codes using the keyboard. It consists of 4 parts. The
first part is available rxvt-unicode has been compiled with
--enable-frills , the rest is available when rxvt-unicode was compiled
with
--enable-iso14755 .
5.1: Basic method
This allows you to enter unicode characters using their hexcode.
Start by pressing and holding both
Control and
Shift , then enter
hex-digits (between one and six). Releasing
Control and
Shift will
commit the character as if it were typed directly. While holding down
Control and
Shift you can also enter multiple characters by pressing
Space , which will commit the current character and lets you start a new
one.
As an example of use, imagine a business card with a japanese e-mail
address, which you cannot type. Fortunately, the card has the e-mail
address printed as hexcodes, e.g.
671d 65e5 . You can enter this easily
by pressing
Control and
Shift , followed by
6-7-1-D-SPACE-6-5-E-5 ,
followed by releasing the modifier keys.
5.2: Keyboard symbols entry method
This mode lets you input characters representing the keycap symbols of
your keyboard, if representable in the current locale encoding.
Start by pressing
Control and
Shift together, then releasing
them. The next special key (cursor keys, home etc.) you enter will not
invoke it's usual function but instead will insert the corresponding
keycap symbol. The symbol will only be entered when the key has been
released, otherwise pressing e.g.
Shift would enter the symbol for
ISO Level 2 Switch , although your intention might have been to enter a
reverse tab (Shift-Tab).
5.3: Screen-selection entry method
While this is implemented already (it's basically the selection
mechanism), it could be extended by displaying a unicode character map.
5.4: Feedback method for identifying displayed characters for later input
This method lets you display the unicode character code associated with
characters already displayed.
You enter this mode by holding down
Control and
Shift together, then
pressing and holding the left mouse button and moving around. The unicode
hex code(s) (it might be a combining character) of the character under the
pointer is displayed until you release
Control and
Shift .
In addition to the hex codes it will display the font used to draw this
character - due to implementation reasons, characters combined with
combining characters, line drawing characters and unknown characters will
always be drawn using the built-in support font.
With respect to conformance, rxvt-unicode is supposed to be compliant to
both scenario A and B of ISO 14755, including part 5.2.
LOGIN STAMP
urxvt tries to write an entry into the utmp(5) file so
that it can be seen via the who(1) command, and can accept messages.
To allow this feature, urxvt must be installed setuid root on
some systems.
COLORS AND GRAPHICS
In addition to the default foreground and background colours,
urxvt can display up to 16 colours (8 ANSI colours plus
high-intensity bold/blink versions of the same). Here is a list of the
colours with their rgb.txt names.
color0
(black)
= Black

It is also possible to specify the colour values of foreground,
background, cursorColor, cursorColor2, colorBD, colorUL as
a number 0-15, as a convenient shorthand to reference the colour name of
color0-color15.
Note that -rv (``reverseVideo: True'') simulates reverse video by
always swapping the foreground/background colours. This is in contrast to
xterm(1) where the colours are only swapped if they have not otherwise
been specified. For example,
urxvt -fg Black -bg White -rv
would yield White on Black, while on xterm(1) it would yield Black
on White.
ENVIRONMENT
urxvt sets the environment variables TERM, COLORTERM
and COLORFGBG. The environment variable WINDOWID is set to the X
window id number of the urxvt window and it also uses and
sets the environment variable DISPLAY to specify which display
terminal to use. urxvt uses the environment variables
RXVTPATH and PATH to find XPM files.
Forked rxvt-unicode, rewrote most of the display code and internal
character handling to store text in unicode, improve xterm
compatibility and apply numerous other bugfixes and extensions.
