NAME
rxvt-unicode - (ouR XVT, unicode), a VT102 emulator for the X window system
SYNOPSIS
urxvt [options] [-e command [ args ]]
DESCRIPTION
rxvt-unicode, version 9.31, 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. That document is also accessible on the World-Wide-Web at
<http://pod.tst.eu/http://cvs.schmorp.de/rxvt-unicode/doc/rxvt.7.pod>.
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 devanagari. 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 right-to-left scripts, such as hebrew: rxvt-unicode adopts the view that bidirectional
algorithms belong in 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 user friendly, 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 its 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 its predecessor, supports things
such as XFT and ISO 14755 that are handy in i18n-environments, is faster, and has a lot bugs less 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 its 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) more 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.
-display displayname
Attempt to open a window on the named X display (the older form -d is still respected. but
deprecated). In the absence of this option, the display specified by the DISPLAY environment variable
is used.
-depth bitdepth
Compile frills: Attempt to find a visual with the given bit depth; resource depth.
[Please note that many X servers (and libXft) are buggy with respect to "-depth 32" and/or alpha
channels, and will cause all sorts of graphical corruption. This is harmless, but we can't do
anything about this, so watch out]
-visual visualID
Compile frills: Use the given visual (see e.g. "xdpyinfo" for possible visual ids) instead of the
default, and also allocate a private colormap. All visual types except for DirectColor are supported.
-geometry geom
Window geometry (-g still respected); resource geometry.
-rv|+rv
Turn on/off simulated reverse video; resource reverseVideo.
-j|+j
Turn on/off jump scrolling (allow multiple lines per refresh); resource jumpScroll.
-ss|+ss
Turn on/off skip scrolling (allow multiple screens per refresh); resource skipScroll.
-fps number
Compile frills: Set the refresh interval (in frames per second or negative seconds); resource
refreshRate.
-fade number
Fade the text by the given percentage when focus is lost. Small values fade a little only, 100
completely replaces all colours by the fade colour; resource fading.
-fadecolor colour
Fade to this colour when fading is used (see -fade). The default colour is opaque black. resource
fadeColor.
-icon file
Compile pixbuf: Use the specified image as application icon. This is used by many window managers,
taskbars and pagers to represent the application window; resource iconFile.
-bg colour
Window background colour; resource background.
-fg colour
Window foreground colour; resource foreground.
-cr colour
The cursor colour; resource cursorColor.
-pr colour
The mouse pointer foreground colour; resource pointerColor.
-pr2 colour
The mouse pointer background colour; resource pointerColor2.
-bd colour
The colour of the border around the text area and between the scrollbar and the text; resource
borderColor.
-fn fontlist
Select the fonts to be used. This is a comma separated list of font names that are checked in order
when trying to find glyphs for 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 its 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).
-fb fontlist
Compile font-styles: The bold font list to use when bold characters are to be printed. See resource
boldFont for details.
-fi fontlist
Compile font-styles: The italic font list to use when italic characters are to be printed. See
resource italicFont for details.
-fbi fontlist
Compile font-styles: The bold italic font list to use when bold italic characters are to be printed.
See resource boldItalicFont for details.
-is|+is
Compile font-styles: Bold/Blink font styles imply high intensity foreground/background (default). See
resource intensityStyles for details.
-name name
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.
-mc milliseconds
Specify the maximum time between multi-click selections.
-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.
-sr|+sr
Put scrollbar on right/left; resource scrollBar_right.
-st|+st
Display rxvt (non XTerm/NeXT) scrollbar without/with a trough; resource scrollBar_floating.
-si|+si
Turn on/off scroll-to-bottom on TTY output inhibit; resource scrollTtyOutput has opposite effect.
-sk|+sk
Turn on/off scroll-to-bottom on keypress; resource scrollTtyKeypress.
-sw|+sw
Turn on/off scrolling with the scrollback buffer as new lines appear. This only takes effect if -si
is also given; resource scrollWithBuffer.
-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.
-uc|+uc
Make the cursor underlined; resource cursorUnderline.
-iconic
Start iconified, if the window manager supports that option. Alternative form is -ic.
-sl number
Save number lines in the scrollback buffer. See resource entry for limits; resource saveLines.
-b number
Compile frills: Internal border of number pixels. See resource entry for limits; resource
internalBorder.
-w number
Compile frills: External border of number pixels. Also, -bw and -borderwidth. See resource entry for
limits; resource 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. If the window manager does not
support MWM hints (e.g. kwin), enables override-redirect mode.
-override-redirect
Compile frills: Sets override-redirect on the window; resource override-redirect.
-dockapp
Sets the initial state of the window to WithdrawnState, which makes window managers that support this
extension treat it as a dockapp.
-sbg
Compile frills: Disable the usage of the built-in block graphics/line drawing characters and just
rely on what the specified fonts provide. Use this if you have a good font and want to use its block
graphic glyphs; resource skipBuiltinGlyphs.
-lsp number
Compile frills: Lines (pixel height) to insert between each row of the display. Useful to work around
font rendering problems; resource lineSpace.
-letsp number
Compile frills: Amount to adjust the computed character width by to control overall letter spacing.
Negative values will tighten up the letter spacing, positive values will space letters out more.
Useful to work around odd font metrics; resource letterSpace.
-tn termname
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.
-e command [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).
Please note that you must specify a program with arguments. If you want to run shell commands, you
have to specify the shell, like this:
urxvt -e sh -c "shell commands"
-title text
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.
-n text
Icon name; the default name is the basename of the program specified after the -e option, if any,
otherwise the application name; resource iconName.
-C Capture system console messages.
-pt style
Compile XIM: input style for input method; OverTheSpot, OffTheSpot, Root; resource preeditType.
If the perl extension "xim-onthespot" is used (which is the default), then additionally the
"OnTheSpot" preedit type is available.
-im text
Compile XIM: input method name. resource inputMethod.
-imlocale string
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. resource imLocale.
-imfont fontset
Set the font set to use for the X Input Method, see resource imFont for more info.
-tcw
Change the meaning of triple-click selection with the left mouse button. Only effective when the
original (non-perl) selection code is in-use. Instead of selecting a full line it will extend the
selection to the end of the logical line only. resource tripleclickwords.
-dpb|+dpb
Compile frills: Disable (or enable) emitting bracketed paste mode sequences (default enabled).
Bracketed paste mode allows programs to detect when something is pasted. Since more and more programs
abuse this, these sequences can be disabled. The command sequences to enable and query paste mode
will still work, but the actual bracket sequences will no longer be emitted. You can also toggle this
from the ctrl-middle-mouse-button menu; resource disablePasteBrackets.
-insecure
Enable "insecure" mode, which currently enables most of the escape sequences that echo strings. See
the resource insecure for more info.
-mod modifier
Override detection of Meta modifier with specified key: alt, meta, hyper, super, mod1, mod2, mod3,
mod4, mod5; resource modifier.
-ssc|+ssc
Turn on/off secondary screen (default enabled); resource secondaryScreen.
-ssr|+ssr
Turn on/off secondary screen scroll (default enabled); resource secondaryScroll.
-rm mode
Compile frills: Sets long line rewrapping behaviour on window resizes to one of auto (the default),
always or never. The latter two modes do the obvious, auto rewraps (acts like always) if scrollback
is non-empty, and wings lines (acts like never) otherwise; resource rewrapMode.
-hold|+hold
Turn on/off hold window after exit support. If enabled, urxvt will not immediately destroy its window
when the program executed within it exits. Instead, it will wait till it is being killed or closed by
the user; resource hold.
-cd path
Sets the working directory for the shell (or the command specified via -e). The path must be an
absolute path and it must exist for urxvt to start; resource chdir.
-xrm string
Works like the X Toolkit option of the same name, by adding the string as if it were specified in a
resource file. Resource values specified this way take precedence over all other resource
specifications.
Note that you need to use the same syntax as in the .Xdefaults file, e.g. "*.background: black". Also
note that all urxvt-specific options can be specified as long-options on the commandline, so use of
-xrm is mostly limited to cases where you want to specify other resources (e.g. for input methods) or
for compatibility with other programs.
-keysym.sym string
Remap a key symbol. See resource keysym.
-embed windowid
Tells urxvt to embed its windows into an already-existing window, which enables applications to
easily embed a terminal.
Right now, urxvt will first unmap/map the specified window, so it shouldn't be a top-level window.
urxvt will also reconfigure it quite a bit, so don't expect it to keep some specific state. It's best
to create an extra subwindow for urxvt and leave it alone.
The window will not be destroyed when urxvt exits.
It might be useful to know that urxvt will not close file descriptors passed to it (except for
stdin/out/err, of course), so you can use file descriptors to communicate with the programs within
the terminal. This works regardless of whether the "-embed" option was used or not.
Here is a short Gtk2-perl snippet that illustrates how this option can be used (a longer example is
in doc/embed):
my $rxvt = new Gtk2::Socket;
$rxvt->signal_connect_after (realize => sub {
my $xid = $_[0]->window->get_xid;
system "urxvt -embed $xid &";
});
-pty-fd file descriptor
Tells urxvt NOT to execute any commands or create a new pty/tty pair but instead use the given file
descriptor as the tty master. This is useful if you want to drive urxvt as a generic terminal
emulator without having to run a program within it.
If this switch is given, urxvt will not create any utmp/wtmp entries and will not tinker with pty/tty
permissions - you have to do that yourself if you want that.
As an extremely special case, specifying -1 will completely suppress pty/tty operations, which is
probably only useful in conjunction with some perl extension that manages the terminal.
Here is a example in perl that illustrates how this option can be used (a longer example is in
doc/pty-fd):
use IO::Pty;
use Fcntl;
my $pty = new IO::Pty;
fcntl $pty, F_SETFD, 0; # clear close-on-exec
system "urxvt -pty-fd " . (fileno $pty) . "&";
close $pty;
# now communicate with rxvt
my $slave = $pty->slave;
while (<$slave>) { print $slave "got <$_>\n" }
Note that, despite what the name might imply, the file descriptor does not need to be a pty, it can
be a bi-directional pipe as well (e.g. a unix domain or tcp socket). While tty operations cannot be
done in this case, urxvt can still be remote controlled with it:
use Socket;
use Fcntl;
socketpair my $URXVT, my $slave, Socket::AF_UNIX, Socket::SOCK_STREAM, Socket::PF_UNSPEC;
fcntl $slave, Fcntl::F_SETFD, 0;
system "exec urxvt -pty-fd " . (fileno $slave) . " &";
close $slave;
syswrite $URXVT, "Type a secret password: ";
my $secret = do { local $/ = "\r"; <$URXVT> };
print "Not so secret anymore: $secret\n";
-pe string
Comma-separated list of perl extension scripts to use (or not to use) in this terminal instance. See
resource perl-ext for details.
RESOURCES
Note: `urxvt --help' gives a list of all resources (long options) compiled into your version. All
resources are also available as long-options.
You can set and change the resources using X11 tools like xrdb. Many distribution do also load settings
from the ~/.Xresources file when X starts. urxvt will consult the following files/resources in order,
with later settings overwriting earlier ones:
1. app-defaults file in $XAPPLRESDIR
2. $HOME/.Xdefaults
3. RESOURCE_MANAGER property on root-window of screen 0
4. SCREEN_RESOURCES property on root-window of the current screen
5. $XENVIRONMENT file OR $HOME/.Xdefaults-<nodename>
6. resources specified via -xrm on the commandline
Note that when reading X resources, urxvt recognizes two class names: Rxvt 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, 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 supported (you might want to check the urxvtperl(3)
manpage for additional settings by perl extensions not documented here):
depth: bitdepth
Compile xft: Attempt to find a visual with the given bit depth; option -depth.
buffered: boolean
Compile xft: Turn on/off double-buffering for xft (default enabled). On some card/driver combination
enabling it slightly decreases performance, on most it greatly helps it. The slowdown is small, so it
should normally be enabled.
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 COLOURS AND GRAPHICS 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.
underlineColor: colour
If set, use the specified colour as the colour for the underline itself. If unset, use the foreground
colour.
highlightColor: colour
If set, use the specified colour as the background for highlighted characters. If unset, use reverse
video.
highlightTextColor: colour
If set and highlightColor is set, use the specified colour as the foreground for highlighted
characters.
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 COLOURS AND GRAPHICS section.
jumpScroll: boolean
True: specify that jump scrolling should be used. When receiving lots of lines, urxvt will only
scroll once a whole screen height of lines has been read, resulting in fewer updates while still
displaying every received line; option -j.
False: specify that smooth scrolling should be used. urxvt will force a screen refresh on each new
line it received; option +j.
skipScroll: boolean
True: (the default) specify that skip scrolling should be used. When receiving lots of lines, urxvt
will only scroll once in a while (around 60 times per second), resulting in far fewer updates. This
can result in urxvt not ever displaying some of the lines it receives; option -ss.
False: specify that everything is to be displayed, even if the refresh is too fast for the human eye
to read anything (or the monitor to display anything); option +ss.
refreshRate: number
Compile frills: When positive, sets the maximum refreshes per second (the default is 60). When zero
or negative, sets the minimum interval between refreshes, negated. That is, positive numbers limit
the number of refreshes per second to that number, similar to a fps limiter in games. A negative
number gets negated and directly sets the minimum interval between refreshes, that is, 10 and -0.1
both specify the same refresh interval (likewise 50 and 0.02). Finally, zero makes urxvt refresh as
fast as possible. Fractional values are supported; option -fps.
fading: number
Fade the text by the given percentage when focus is lost; option -fade.
fadeColor: colour
Fade to this colour, when fading is used (see fading:). The default colour is black; option
-fadecolor.
iconFile: file
Set the application icon pixmap; option -icon.
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 rxvt
(non XTerm/NeXT) scrollbar.
borderColor: colour
The colour of the border around the text area and between the scrollbar and the text.
font: fontlist
Select the fonts to be used. This is a comma separated list of font names that are checked in order
when trying to find glyphs for 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; 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.
For example, this font resource
URxvt.font: 9x15bold,\
-misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
-misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
[codeset=JISX0208]xft:Kochi Gothic:antialias=false, \
xft:Code2000:antialias=false
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 fewer
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.
intensityStyles: boolean
When font styles are not enabled, or this option is enabled (True, option -is, the default),
bold/blink font styles imply high intensity foreground/background colours. Disabling this option
(False, option +is) disables this behaviour, the high intensity colours are not reachable.
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.
mapAlert: boolean
True: de-iconify (map) on receipt of a bell character. False: no de-iconify (map) on receipt of a
bell character [default].
urgentOnBell: boolean
True: set the urgency hint for the wm on receipt of a bell character. False: do not set the urgency
hint [default].
urxvt resets the urgency hint on every focus change.
visualBell: boolean
True: use visual bell on receipt of a bell character; option -vb. False: no visual bell [default];
option +vb.
loginShell: boolean
True: start as a login shell by prepending a `-' to argv[0] of the shell; option -ls. False: start as
a normal sub-shell [default]; option +ls.
multiClickTime: number
Specify the maximum time in milliseconds between multi-click select events. The default is 500
milliseconds; option -mc.
utmpInhibit: boolean
True: inhibit writing record into the system log file utmp; option -ut. False: write record into the
system log file utmp [default]; option +ut.
print-pipe: string
Specify a command pipe for vt100 printer [default lpr(1)]. Use Print to initiate a screen dump to the
printer and Ctrl-Print or Shift-Print to include the scrollback as well.
The string will be interpreted as if typed into the shell as-is.
Example:
URxvt.print-pipe: cat > $(TMPDIR=$HOME mktemp urxvt.XXXXXX)
This creates a new file in your home directory with the screen contents every time you hit "Print".
scrollstyle: mode
Set scrollbar style to rxvt, plain, next or xterm. plain is the author's favourite.
thickness: number
Set the scrollbar width in pixels.
scrollBar: boolean
True: enable the scrollbar [default]; option -sb. False: disable the scrollbar; option +sb.
scrollBar_right: boolean
True: place the scrollbar on the right of the window; option -sr. False: place the scrollbar on the
left of the window; option +sr.
scrollBar_floating: boolean
True: display an rxvt scrollbar without a trough; option -st. False: display an rxvt scrollbar with
a trough; option +st.
scrollBar_align: mode
Align the top, bottom or centre [default] of the scrollbar thumb with the pointer on middle button
press/drag.
scrollTtyOutput: boolean
True: scroll to bottom when tty receives output; option -si. False: do not scroll to bottom when tty
receives output; option +si.
scrollWithBuffer: boolean
True: scroll with scrollback buffer when tty receives new lines (i.e. try to show the same lines)
and scrollTtyOutput is False; option -sw. False: do not scroll with scrollback buffer when tty
receives 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 1000]; option -sl.
internalBorder: number
Internal border of number pixels. This resource is limited to 100; option -b.
externalBorder: number
External border of number pixels. This resource is limited to 100; option -w, -bw, -borderwidth.
borderLess: boolean
Set MWM hints to request a borderless window, i.e. if honoured by the WM, the rxvt-unicode window
will not have window decorations; option -bl.
skipBuiltinGlyphs: boolean
Compile frills: Disable the usage of the built-in block graphics/line drawing characters and just
rely on what the specified fonts provide. Use this if you have a good font and want to use its block
graphic glyphs; option -sbg.
termName: termname
Specifies the terminal type name to be set in the TERM environment variable; option -tn.
lineSpace: number
Specifies number of lines (pixel height) to insert between each row of the display [default 0];
option -lsp.
meta8: boolean
True: handle Meta (Alt) + keypress to set the 8th bit. False: handle Meta (Alt) + keypress as an
escape prefix [default].
mouseWheelScrollPage: boolean
True: the mouse wheel scrolls a page full. False: the mouse wheel scrolls five lines [default].
pastableTabs: boolean
True: store tabs as wide characters. False: interpret tabs as cursor movement only; option "-ptab".
cursorBlink: boolean
True: blink the cursor. False: do not blink the cursor [default]; option -bc.
cursorUnderline: boolean
True: Make the cursor underlined. False: Make the cursor a box [default]; option -uc.
pointerBlank: boolean
True: blank the pointer when a key is pressed or after a set number of seconds of inactivity. False:
the pointer is always visible [default].
pointerColor: colour
Mouse pointer foreground colour.
pointerColor2: colour
Mouse pointer background colour.
pointerShape: string
Compile frills: Specifies the name of the mouse pointer shape [default xterm]. See the macros in the
X11/cursorfont.h include file for possible values (omit the "XC_" prefix).
pointerBlankDelay: number
Specifies number of seconds before blanking the pointer [default 2]. Use a large number (e.g.
987654321) to effectively disable the timeout.
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, with control, 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 (whitespace delimiting is added
automatically if resource is given).
When the perl selection extension is in use (the default if compiled in, see the urxvtperl(3)
manpage), a suitable regex using these characters will be created (if the resource exists, otherwise,
no regex will be created). In this mode, characters outside ISO-8859-1 can be used.
When the selection extension is not used, only ISO-8859-1 characters can be used. If not specified,
the built-in default is used:
BACKSLASH `"'&()*,;<=>?@[]^{|}
preeditType: style
OnTheSpot, OverTheSpot, OffTheSpot, Root; option -pt.
inputMethod: name
name of inputMethod to use; option -im.
imLocale: name
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; option -imlocale.
imFont: fontset
Specify the font-set used for XIM styles "OverTheSpot" or "OffTheSpot". It must be a standard X font
set (XLFD patterns separated by commas), i.e. it's not in the same format as the other font lists
used in urxvt. The default will be set-up to chose *any* suitable found found, preferably one or two
pixels differing in size to the base font. option -imfont.
tripleclickwords: boolean
Change the meaning of triple-click selection with the left mouse button. Instead of selecting a full
line it will extend the selection to the end of the logical line only; option -tcw.
disablePasteBrackets: boolean
Prevent emission of paste bracket sequences; option -dpb.
insecure: boolean
Enable "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 through a mail client displaying mail bodies unfiltered or through write(1) or any
other means. Therefore, these sequences are disabled by default. (Note that many other terminals,
including xterm, have these sequences enabled by default, which doesn't make it safer, though).
You can enable them by setting this boolean resource or specifying -insecure as an option. At the
moment, this enables display-answer, locale, findfont, icon label and window title requests.
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: boolean
Turn on/off secondary screen (default enabled).
rewrapMode: mode
Sets long line rewrap behaviour on window resize to one of auto (default), always or never.
secondaryScroll: boolean
Turn on/off secondary screen scroll (default enabled). If this option is enabled, scrolls on the
secondary screen will change the scrollback buffer and, when secondaryScreen is off, switching
to/from the secondary screen will instead scroll the screen up.
hold: boolean
Turn on/off hold window after exit support. If enabled, urxvt will not immediately destroy its window
when the program executed within it exits. Instead, it will wait till it is being killed or closed by
the user.
chdir: path
Sets the working directory for the shell (or the command specified via -e). The path must be an
absolute path and it must exist for urxvt to start. If it isn't specified then the current working
directory will be used; option -cd.
keysym.sym: action
Compile frills: Associate action with keysym sym. The intervening resource name keysym. cannot be
omitted.
Using this resource, you can map key combinations such as "Ctrl-Shift-BackSpace" to various actions,
such as outputting a different string than would normally result from that combination, making the
terminal scroll up or down the way you want it, or any other thing an extension might provide.
The key combination that triggers the action, sym, has the following format:
(modifiers-)key
Where modifiers can be any combination of the following full or abbreviated modifier names:
ISOLevel3 I
AppKeypad K
Control C
NumLock N
Shift S
Meta M or A
Lock L
Mod1 1
Mod2 2
Mod3 3
Mod4 4
Mod5 5
The NumLock, Meta and ISOLevel3 modifiers are usually aliased to whatever modifier the NumLock key,
Meta/Alt keys or ISO Level3 Shift/AltGr keys are being mapped. AppKeypad is a synthetic modifier
mapped to the current application keymap mode state.
Due the the large number of modifier combinations, a key mapping will match if at least the specified
identifiers are being set, and no other key mappings with those and more bits are being defined. That
means that defining a mapping for "a" will automatically provide definitions for "Meta-a", "Shift-a"
and so on, unless some of those are defined mappings themselves. See the "builtin:" action, below,
for a way to work around this when this is a problem.
The spelling of key depends on your implementation of X. An easy way to find a key name is to use the
xev(1) command. You can find a list by looking for the "XK_" macros in the X11/keysymdef.h include
file (omit the "XK_" prefix). Alternatively you can specify key by its hex keysym value (0x0000 -
0xFFFF).
As with any resource value, the action string may contain backslash escape sequences ("\n": newline,
"\\": backslash, "\000": octal number), see RESOURCES in "man 7 X" for further details.
An action starts with an action prefix that selects a certain type of action, followed by a colon. An
action string without colons is interpreted as a literal string to pass to the tty (as if it was
prefixed with "string:").
The following action prefixes are known - extensions can provide additional prefixes:
string:STRING
If the action starts with "string:" (or otherwise contains no colons), then the remaining
"STRING" will be passed to the program running in the terminal. For example, you could replace
whatever Shift-Tab outputs by the string "echo rm -rf /" followed by a newline:
URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
This could in theory be used to completely redefine your keymap.
In addition, for actions of this type, you can define a range of keysyms in one shot by loading
the "keysym-list" perl extension and providing an action with pattern list/PREFIX/MIDDLE/SUFFIX,
where the delimiter `/' should be a character not used by the strings.
Its usage can be demonstrated by an example:
URxvt.keysym.M-C-0x61: list|\033<|abc|>
The above line is equivalent to the following three lines:
URxvt.keysym.Meta-Control-0x61: string:\033<a>
URxvt.keysym.Meta-Control-0x62: string:\033<b>
URxvt.keysym.Meta-Control-0x63: string:\033<c>
command:STRING
If action takes the form of "command:STRING", the specified STRING is interpreted and executed as
urxvt's control sequence (basically the opposite of "string:" - instead of sending it to the
program running in the terminal, it will be treated as if it were program output). This is most
useful to feed command sequences into urxvt.
For example the following means "change the current locale to "zh_CN.GBK" when Control-Meta-c is
being pressed":
URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
The following example will map Control-Meta-1 and Control-Meta-2 to the fonts "suxuseuro" and
"9x15bold", so you can have some limited font-switching at runtime:
URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
Other things are possible, e.g. resizing (see urxvt(7) for more info):
URxvt.keysym.M-C-3: command:\033[8;25;80t
URxvt.keysym.M-C-4: command:\033[8;48;110t
builtin:
The builtin action is the action that urxvt would execute if no key binding existed for the key
combination. The obvious use is to undo the effect of existing bindings. The not so obvious use
is to reinstate bindings when another binding overrides too many modifiers.
For example if you overwrite the "Insert" key you will disable urxvt's "Shift-Insert" mapping. To
re-enable that, you can poke "holes" into the user-defined keymap using the "builtin:"
replacement:
URxvt.keysym.Insert: <my insert key sequence>
URxvt.keysym.S-Insert: builtin:
The first line defines a mapping for "Insert" and any combination of modifiers. The second line
re-establishes the default mapping for "Shift-Insert".
builtin-string:
This action is mainly useful to restore string mappings for keys that have predefined actions in
urxvt. The exact semantics are a bit difficult to explain - basically, this action will send the
string to the application that would be sent if urxvt wouldn't have a built-in action for it.
An example might make it clearer: urxvt normally pastes the selection when you press
"Shift-Insert". With the following bindings, it would instead emit the (undocumented, but what
applications running in the terminal might expect) sequence "ESC [ 2 $" instead:
URxvt.keysym.S-Insert: builtin-string:
URxvt.keysym.C-S-Insert: builtin:
The first line disables the paste functionality for that key combination, and the second
reinstates the default behaviour for "Control-Shift-Insert", which would otherwise be overridden.
Similarly, to let applications gain access to the "C-M-c" (copy to clipboard) and "C-M-v" (paste
clipboard) key combination, you can do this:
URxvt.keysym.C-M-c: builtin-string:
URxvt.keysym.C-M-v: builtin-string:
EXTENSION:STRING
An action of this form invokes the action STRING, if any, provided by the urxvtperl(3) extension
EXTENSION. The extension will be loaded automatically if necessary.
Not all extensions define actions, but popular extensions that do include the selection and
matcher extensions (documented in their own manpages, urxvt-selection(1) and urxvt-matcher(1),
respectively).
From the silly examples department, this will rot13-"encrypt" urxvt's selection when Alt-Control-
c is pressed on typical PC keyboards:
URxvt.keysym.M-C-c: selection:rot13
perl:STRING *DEPRECATED*
This is a deprecated way of invoking commands provided by perl extensions. It is still supported,
but should not be used anymore.
perl-ext-common: string
perl-ext: string
Comma-separated list(s) of perl extension scripts (default: "default") to use in this terminal
instance; option -pe.
Extension names can be prefixed with a "-" sign to remove them again, in case they had been specified
earlier. This can be useful to selectively disable some extensions loaded by default, or specified
via the "perl-ext-common" resource. For example, "default,-selection" will use all the default
extensions except "selection".
To prohibit autoloading of extensions, you can prefix them with "/", which will make urxvt refuse to
automatically load them (this can be overridden, however, by specifying the extension name again
without a prefix, though). This does not prohibit extensions themselves loading other extensions. For
example, "default,/background" will keep the "background" extension from being loaded when a
background OSC sequence is received.
The default set includes the "selection", "option-popup", "selection-popup", "readline",
"searchable-scrollback" and "confirm-paste" extensions, as well as any extensions which are mentioned
in keysym resources.
Any extension such that a corresponding resource is given on the command line is automatically
appended to perl-ext.
Each extension is looked up in the library directories, loaded if necessary, and bound to the current
terminal instance. When the library search path contains multiple extension files of the same name,
then the first one found will be used.
If both of these resources are the empty string, then the perl interpreter will not be initialized.
The rationale for having two options is that perl-ext-common will be used for extensions that should
be available to all instances, while perl-ext is used for specific instances.
perl-eval: string
Perl code to be evaluated when all extensions have been registered. See the urxvtperl(3) manpage.
perl-lib: path
Colon-separated list of additional directories that hold extension scripts. When looking for perl
extensions, urxvt will first look in these directories, then in $URXVT_PERL_LIB, $HOME/.urxvt/ext and
lastly in /usr/lib/x86_64-linux-gnu/urxvt/perl/.
See the urxvtperl(3) manpage.
selection.pattern-idx: perl-regex
Additional selection patterns, see the urxvtperl(3) manpage for details.
selection-autotransform.idx: perl-transform
Selection auto-transform patterns, see the urxvtperl(3) manpage for details.
searchable-scrollback: keysym *DEPRECATED*
This resource is deprecated and will be removed. Use a keysym resource instead, e.g.:
URxvt.keysym.M-s: searchable-scrollback:start
url-launcher: string
Specifies the program to be started with a URL argument. Used by the "selection-popup" and "matcher"
perl extensions.
transient-for: windowid
Compile frills: Sets the WM_TRANSIENT_FOR property to the given window id.
override-redirect: boolean
Compile frills: Sets override-redirect for the terminal window, making it almost invisible to window
managers; option -override-redirect.
iso14755: boolean
Turn on/off ISO 14755 (default enabled).
iso14755_52: boolean
Turn on/off ISO 14755 5.2 mode (default enabled).
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.
THE SELECTION: SELECTING AND PASTING TEXT
The behaviour of text selection and insertion/pasting mechanism is similar to xterm(1).
Selecting:
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
logical line (which can span multiple screen lines), unless modified by resource tripleclickwords.
Starting a selection while pressing the Meta key (or Meta+Ctrl keys) (Compile: frills) will create a
rectangular selection instead of a normal one. In this mode, every selected row becomes its own line
in the selection, and trailing whitespace is visually underlined and removed from the selection.
Pasting:
Pressing and releasing the Middle mouse button in an urxvt window causes the value of the PRIMARY
selection (or CLIPBOARD with the Meta modifier) to be inserted as if it had been typed on the
keyboard.
Pressing Shift-Insert causes the value of the PRIMARY selection to be inserted too.
rxvt-unicode also provides the bindings Ctrl-Meta-c and <Ctrl-Meta-v> to interact with the CLIPBOARD
selection. The first binding causes the value of the internal selection to be copied to the CLIPBOARD
selection, while the second binding causes the value of the CLIPBOARD selection to be inserted.
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, e.g.:
printf '\e]710;%s\007' "9x15bold,xft:Kochi Gothic"
You can use keyboard shortcuts, too:
URxvt.keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
URxvt.keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
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 if 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 its 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 may need to be installed setuid root on some systems
or setgid to root or to some other group on others.
COLOURS AND GRAPHICS
In addition to the default foreground and background colours, urxvt can display up to 88/256 colours: 8
ANSI colours plus high-intensity (potentially bold/blink) versions of the same, and 72 (or 240 in 256
colour mode) colours arranged in an 4x4x4 (or 6x6x6) colour RGB cube plus a 8 (24) colour greyscale ramp.
urxvt supports direct 24-bit fg/bg RGB colour escapes " ESC [ 38 ; 2 ; R ; G ; Bm " / " ESC [ 48 ; 2; R ;
G ; Bm ". However the number of 24-bit colours that can be used is limited: an internal 7x7x5 (256 colour
mode) or 6x6x4 (88 colour mode) colour cube is used to index into the 24-bit colour space. When indexing
collisions happen, the nearest old colour in the cube will be adapted to the new 24-bit RGB colour. That
means one cannot use many similar 24-bit colours. It's typically not a problem in common scenarios.
Here is a list of the ANSI colours with their names.
color0 (black) = Black
color1 (red) = Red3
color2 (green) = Green3
color3 (yellow) = Yellow3
color4 (blue) = Blue3
color5 (magenta) = Magenta3
color6 (cyan) = Cyan3
color7 (white) = AntiqueWhite
color8 (bright black) = Grey25
color9 (bright red) = Red
color10 (bright green) = Green
color11 (bright yellow) = Yellow
color12 (bright blue) = Blue
color13 (bright magenta) = Magenta
color14 (bright cyan) = Cyan
color15 (bright white) = White
foreground = Black
background = White
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.
The following text gives values for the standard 88 colour mode (and values for the 256 colour mode in
parentheses).
The RGB cube uses indices 16..79 (16..231) using the following formulas:
index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
index_256 = (r * 6 + g) * 6 + b + 16 # r, g, b = 0..5
The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10% steps (1/26 to 25/26 in 1/26
steps) - black and white are already part of the RGB cube.
Together, all those colours implement the 88 (256) colour xterm colours. Only the first 16 can be changed
using resources currently, the rest can only be changed via command sequences ("escape codes").
Applications are advised to use terminfo or command sequences to discover number and RGB values of all
colours (yes, you can query this...).
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.
ALPHA CHANNEL SUPPORT
If Xft support has been compiled in and as long as Xft/Xrender/X don't get their act together, rxvt-
unicode will do its own alpha channel management:
You can prefix any colour with an opaqueness percentage enclosed in brackets, i.e. "[percent]", where
"percent" is a decimal percentage (0-100) that specifies the opacity of the colour, where 0 is completely
transparent and 100 is completely opaque. For example, "[50]red" is a half-transparent red, while
"[95]#00ff00" is an almost opaque green. This is the recommended format to specify transparency values,
and works with all ways to specify a colour.
For complete control, rxvt-unicode also supports "rgba:rrrr/gggg/bbbb/aaaa" (exactly four hex
digits/component) colour specifications, where the additional "aaaa" component specifies opacity (alpha)
values. The minimum value of 0000 is completely transparent, while "ffff" is completely opaque). The two
example colours from earlier could also be specified as "rgba:ff00/0000/0000/8000" and
"rgba:0000/ff00/0000/f332".
You probably need to specify "-depth 32", too, to force a visual with alpha channels, and have the luck
that your X-server uses ARGB pixel layout, as X is far from just supporting ARGB visuals out of the box,
and rxvt-unicode just fudges around.
For example, the following selects an almost completely transparent black background, and an almost
opaque pink foreground:
urxvt -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
When not using a background image, then the interpretation of the alpha channel is up to your compositing
manager (most interpret it as transparency of course).
When using a background pixmap or pseudo-transparency, then the background colour will always behave as
if it were completely transparent (so the background image shows instead), regardless of how it was
specified, while other colours will either be transparent as specified (the background image will show
through) on servers supporting the RENDER extension, or fully opaque on servers not supporting the RENDER
EXTENSION.
Please note that due to bugs in Xft, specifying alpha values might result in garbage being displayed when
the X-server does not support the RENDER extension.
ENVIRONMENT
urxvt sets and/or uses the following environment variables:
TERM
Normally set to "rxvt-unicode", unless overwritten at configure time, via resources or on the command
line.
COLORTERM
Either "rxvt", "rxvt-xpm", depending on whether urxvt was compiled with background image support, and
optionally with the added extension "-mono" to indicate that rxvt-unicode runs on a monochrome
screen.
COLORFGBG
Set to a string of the form "fg;bg" or "fg;xpm;bg", where "fg" is the colour code used as default
foreground/text colour (or the string "default" to indicate that the default-colour escape sequence
is to be used), "bg" is the colour code used as default background colour (or the string "default"),
and "xpm" is the string "default" if urxvt was compiled with background image support. Libraries like
"ncurses" and "slang" can (and do) use this information to optimize screen output.
WINDOWID
Set to the (decimal) X Window ID of the urxvt window (the toplevel window, which usually has
subwindows for the scrollbar, the terminal window and so on).
TERMINFO
Set to the terminfo directory iff urxvt was configured with "--with-terminfo=PATH".
DISPLAY
Used by urxvt to connect to the display and set to the correct display in its child processes if
"-display" isn't used to override. It defaults to ":0" if it doesn't exist.
SHELL
The shell to be used for command execution, defaults to "/bin/sh".
RXVT_SOCKET [sic]
The unix domain socket path used by urxvtc(1) and urxvtd(1).
Default $HOME/.urxvt/urxvtd-<nodename>.
URXVT_PERL_LIB
Additional :-separated library search path for perl extensions. Will be searched after -perl-lib but
before ~/.urxvt/ext and the system library directory.
URXVT_PERL_VERBOSITY
See urxvtperl(3).
HOME
Used to locate the default directory for the unix domain socket for daemon communications and to
locate various resource files (such as ".Xdefaults")
XAPPLRESDIR
Directory where application-specific X resource files are located.
XENVIRONMENT
If set and accessible, gives the name of a X resource file to be loaded by urxvt.
FILES
/etc/X11/rgb.txt
Colour names.
