NAME

       rxvt-unicode - (ouR XVT, unicode), a VT102 emulator for the X window
       system

SYNOPSIS

       urxvt [options] [-e command [ args ]]

DESCRIPTION

       rxvt-unicode, version 9.14, 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.

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 xft: 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]

       -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.

       -tr|+tr
           Turn on/off pseudo-transparency by using the root pixmap as
           background; resource transparent.

           -ip is still accepted as an obsolete alias but will be removed in
           future versions.

       -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.

       -tint colour
           Tint the transparent background with the given colour; resource
           tintColor.

       -sh number
           Darken (0 .. 99) or lighten (101 .. 200) the transparent
           background.  A value of 100 means no shading; resource shading.

       -blt string
           Specify background blending type. If background pixmap is specified
           at the same time as transparency - such pixmap will be blended over
           the transparent background, using the method specified. Supported
           values are: add, alphablend, allanon - colour values averaging,
           colorize, darken, diff, dissipate, hue, lighten, overlay, saturate,
           screen, sub, tint, value. The default is alpha-blending. Compile
           afterimage; resource blendType.

       -blr HxV
           Apply Gaussian Blur with the specified radii to the transparent
           background. If a single number is specified - both vertical and
           horizontal radii are considered to be the same. Setting one of the
           radii to 1 and another to a large number creates interesting
           effects on some backgrounds. Maximum radius value is 128; resource
           blurRadius.

       -icon file
           Compile afterimage or 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.

       -pixmap file[;oplist]
           Compile afterimage or pixbuf: Specify image file for the background
           and also optionally specify a list of operations to modify it. Note
           you may need to add quotes to avoid special shell interpretation of
           the ";" in the command-line; for more details see resource
           backgroundPixmap.

       -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.

       -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.

       -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.

       -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.

       -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.

       -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" }

       -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.

       transparent: boolean
           Turn on/off pseudo-transparency by using the root pixmap as
           background.

           inheritPixmap is still accepted as an obsolete alias but will be
           removed in future versions.

       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.

       tintColor: colour
           Tint the transparent background with the given colour. If the
           RENDER extension is not available only black, red, green, yellow,
           blue, magenta, cyan and white tints can be performed server-side.
           Note that a black tint yields a completely black image while a
           white tint yields the image unchanged; option -tint.

       shading: number
           Darken (0 .. 99) or lighten (101 .. 200) the transparent
           background.  A value of 100 means no shading; option -sh.

       blendType: string
           Specify background blending type; option -blt.

       blurRadius: number
           Apply gaussian blur with the specified radius to the transparent
           background; option -blr.

       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.

       backgroundPixmap: file[;oplist]
           Use the specified image file for the background and also optionally
           specify a colon separated list of operations to modify it.
           Supported operations are:

           WxH+X+Y
               sets scale and position. "W" / "H" specify the
               horizontal/vertical scale (percent), and "X" / "Y" locate the
               image centre (percent). A scale of 0 disables scaling. The
               maximum permitted scale is 1000.

           op=tile
               enables tiling

           op=keep-aspect
               maintain the image aspect ratio when scaling

           op=root-align
               use the position of the terminal window relative to the root
               window as the image offset, simulating a root window background

           The default scale and position setting is "100x100+50+50".
           Alternatively, a predefined set of templates can be used to achieve
           the most common setups:

           style=tiled
               the image is tiled with no scaling. Equivalent to
               0x0+0+0:op=tile

           style=aspect-stretched
               the image is scaled to fill the whole window maintaining the
               aspect ratio and centered. Equivalent to
               100x100+50+50:op=keep-aspect

           style=stretched
               the image is scaled to fill the whole window. Equivalent to
               100x100

           style=centered
               the image is centered with no scaling. Equivalent to 0x0+50+50

           style=root-tiled
               the image is tiled with no scaling and using 'root'
               positioning.  Equivalent to 0x0:op=tile:op=root-align

           If multiple templates are specified the last one wins. Note that a
           template overrides all the scale, position and operations settings.

           If used in conjunction with -tr option, the specified pixmap will
           be blended over the transparent background using alpha-blending. If
           afterimage support has been compiled in it is possible to choose
           other blending types with -blt "type" option.

       path: path
           Specify the colon-delimited search path for finding background
           image files.

       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.

       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 64]. This
           resource is limited on most machines to 65535; 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.

       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
           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.

       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 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).

       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: string
           Compile frills: Associate string with keysym sym. The intervening
           resource name keysym. cannot be omitted.

           The format of sym is "(modifiers-)key", where modifiers can be any
           combination of ISOLevel3, AppKeypad, Control, NumLock, Shift, Meta,
           Lock, Mod1, Mod2, Mod3, Mod4, Mod5, and the abbreviated I, K, C, N,
           S, M, A, L, 1, 2, 3, 4, 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.

           The spellings of key can be obtained by using xev(1) command or
           searching keysym macros from /usr/X11R6/include/X11/keysymdef.h and
           omitting the prefix XK_. Alternatively you can specify key by its
           hex keysym value (0x0000 - 0xFFFF). Note that the lookup of syms is
           not performed in an exact manner; however, the closest match is
           assured.

           string may contain escape values ("\n": newline, "\000": octal
           number), see RESOURCES in "man 7 X" for further details.

           You can define a range of keysyms in one shot by loading the
           "keysym-list" perl extension and providing a string 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:    \033<a>
             URxvt.keysym.Meta-Control-0x62:    \033<b>
             URxvt.keysym.Meta-Control-0x63:    \033<c>

           If string takes the form of "command:STRING", the specified STRING
           is interpreted and executed as urxvt's control sequence. 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

           If string takes the form "perl:STRING", then the specified STRING
           is passed to the "on_user_command" perl handler. See the
           urxvtperl(3) manpage. For example, the selection extension
           (activated via "urxvt -pe selection") listens for "selection:rot13"
           events:

             URxvt.keysym.M-C-c: perl:selection:rot13

           Due the the large number of modifier combinations, a defined 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 key map for "a" will
           automatically provide definitions for "Meta-a", "Shift-a" and so
           on, unless some of those are defined mappings themselves.

           Unfortunately, this will override built-in key mappings. 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".

           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

       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 prohibit using
           them. 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
           extension except "selection".

           Extension names can also be followed by an argument in angle
           brackets (e.g.  "searchable-scrollback<M-s>", which binds the
           hotkey for searchable scrollback to Alt/Meta-s). Mentioning the
           same extension multiple times with different arguments will pass
           multiple arguments to the extension.

           Each extension is looked up in the library directories, loaded if
           necessary, and bound to the current terminal instance.

           If both of these resources are the empty string, then the perl
           interpreter will not be initialized. The idea behind 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 $HOME/.urxvt/ext and lastly in
           /usr/lib/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
           Sets the hotkey that starts the incremental scrollback buffer
           search (default: "M-s").

       urlLauncher: 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.

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".

       o   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.

       o   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).

       o   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.

       o   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.

       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 * 16 + g) * 16 + b + 16   # r, g, b = 0..15

       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 it's 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
           The unix domain socket path used by urxvtc(1) and urxvtd(1).

           Default $HOME/.urxvt/urxvtd-<nodename>.

       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.
