rxvt (ouR XVT) - a VT102 emulator for the X window system
SYNOPSIS
rxvt [options] [-e command [ args ]]
DESCRIPTION
rxvt, version 2.4.7, is a colour vt102 terminal emulator
intended as an xterm(1) replacement for users who do not require
features such as Tektronix 4014 emulation and toolkit-style configurability.
As a result, rxvt uses much less swap space -- a significant
advantage on a machine serving many X sessions.
OPTIONS
The rxvt 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.
Note that rxvt 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: `rxvt --loginShell --color1 Orange'.
-help, --help
Print out a message describing available options.
-displaydisplayname
Attempt to open a window on the named X display (-d still
respected). In the absence of this option, the display specified
by the DISPLAY environment variable is used.
-geometrygeom
Window geometry (-g still respected);
resource geometry.
-pixmap:file[;geom]
Specify XPM file for the background and also optionally specify its
scaling with a geometry string. Note you may need to add quotes to
avoid special shell interpretation of the `;' in the command-line;
resource backgroundPixmap.

-ecommand [arguments]
Run the command with its command-line arguments in the rxvt
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).

Window title -T still respected); the default title is the
basename of the program specified after the \f3\-e\fP option, if
any, otherwise the application name;

RESOURCES (available also as long-options)
rxvt accepts application defaults set in XAPPLOADDIR/Rxvt (compile-time
defined: usually /usr/lib/X11/app-defaults/Rxvt) and resources set in
~/.Xdefaults or ~/.Xresources. Note that when reading X resources,
rxvt recognizes two class names: XTerm and Rxvt. The class name
XTerm allows resources common to both rxvt and xterm to be easily
configured, while the class name Rxvt allows resources unique to rxvt,
notably colours and key-handling, to be shared between different rxvt
configurations. If no resources are specified, suitable defaults will be
used. Command-line arguments can be used to override resource settings. The
following resources are allowed:
geometry:geom
Create the window with the specified X window geometry [default
80x24];
option -geometry.
background:colour
Use the specified colour as the window's background colour [default
White];
option -bg.
foreground:colour
Use the specified colour as the window's foreground colour [default
Black];
option -fg.
colorn:colour
Use the specified colour for the colour value n, where 0-7
corresponds to low-intensity (normal) colours and 8-15 corresponds to
high-intensity (bold = bright foreground, blink = bright
background) colours. The canonical names are as follows:
0=black, 1=red, 2=green, 3=yellow, 4=blue, 5=magenta, 6=cyan, 7=white,
but the actual colour names used are listed in the
COLORS AND GRAPHICS section.
colorBD:colour
Use the specified colour to display bold characters when the
foreground colour is the default.
colorUL:colour
Use the specified colour to display underlined characters when the
foreground colour is the default.
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:booleanTrue: simulate reverse video by foreground and background colours;
option -rv,
False: regular screen colours [default];
option +rv.
See note in COLORS AND GRAPHICS section.
scrollColor:colour
Use the specified colour for the scrollbar [default #B2B2B2].
throughColor:colour
Use the specified colour of the scrollbar's through area [default
#A2A2A2].
backgroundPixmap:file[;geom]
Use the specified XPM file (note the `.xpm' extension is optional)
for the background and also optionally specify its scaling with a
geometry string WxH+X+Y, in which "W" / "H" specify the
horizontal/vertical scale (percent) and "X" / "Y" locate the
image centre (percent). A scale of 0 displays the image with tiling.
A scale of 1 displays the image without any scaling. A scale of 2 to
9 specifies an integer number of images in that direction. No image
will be magnified beyond 10 times its original size. The maximum
permitted scale is 1000. [default 0x0+50+50]

font2:
6x13
font3:
8x13
font4:
9x15
boldFont:fontname
Specify the name of the bold font to use if colorBD has not been

of the shell;
option -ls.
False: start as a normal sub-shell [default];
option +ls.
utmpInhibit:booleanTrue: 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.
scrollBar:booleanTrue: enable the scrollbar [default];
option -sb.
False: disable the scrollbar;
option +sb.
Note that the scrollbar type (with/without arrows) is compile-time
selected.

cutchars:string
The characters used as delimiters for double-click word selection.
The built-in default: BACKSLASH `"'&()*,;<=>?@[]{|}
keysym.sym: string
Associate string with keysym sym (0xFF00 - 0xFFFF). It
may contain escape values (\a: bell, \b: backspace, \e, \E: escape,
\n: newline, \r: return, \t: tab, \000: octal number) or control
characters (^?: delete, ^@: null, ^A ...) and may enclosed with
double quotes so that it can start or end with whitespace. The
intervening resource name keysym. cannot be omitted. This
resource is only available when compiled with KEYSYM_RESOURCE.
THE SCROLLBAR
Lines of text that scroll off the top of the rxvt window (resource:
saveLines) and can be scrolled back using the scrollbar or by keystrokes.
The normal rxvt scrollbar has arrows and its behaviour is fairly
intuitive. The xterm-scrollbar is without arrows and its behaviour
mimics that of xterm
Scroll down with Button1 (xterm-scrollbar) or Shift-Next.
Scroll up with Button3 (xterm-scrollbar) or Shift-Prior.
Continuous scroll with Button2.
MOUSE REPORTING
To temporarily override mouse reporting, for either the scrollbar or the
normal text selection/insertion, hold either the Shift or the Meta (Alt) key
while performing the desired mouse action.
If mouse reporting mode is active, the normal scrollbar actions are disabled
-- on the assumption that we are using a fullscreen application.
Instead, pressing Button1 and Button3 sends
ESC[6~ (Next) and ESC[5~ (Prior), respectively.
Similarly, clicking on the up and down arrows sends ESC[A (Up) and
ESC[B (Down), respectively.
TEXT SELECTION AND INSERTION
The behaviour of text selection and insertion mechanism is similar to
xterm(1).
Selection:
Left click at the beginning of the region, drag to the end of the
region and release; Right click to extend the marked region;
Left double-click to select a word; Left triple-click to select
the entire line.
Insertion:
Pressing and releasing the Middle mouse button (or Shift-Insert)
in an rxvt window causes the current text selection to be inserted
as if it had been typed on the keyboard.
CHANGING FONTS
You can change fonts on-the-fly, which is to say cycle through the default
font and others of various sizes, by using Shift-KP_Add and
Shift-KP_Subtract. Or, alternatively (if enabled) with
Alt-> and Alt-<, where the actual key
can be selected using resources smallfont_key/bigfont_key.
LOGIN STAMP
rxvt 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, rxvt must be installed setuid root on some systems.
COLORS AND GRAPHICS
If graphics support was enabled at compile-time, rxvt can be queried
with ANSI escape sequences and can address individual pixels instead of
text characters. Note the graphics support is still considered beta code.
In addition to the default foreground and background colours, rxvt
can display up to 16 colours (8 ANSI colours plus high-intensity bold/blink
versions of the same).
Here is a list of the colours with their rgb.txt names.
color0
(black)
= Black
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.
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,
rxvt -fg Black -bg White -rv
would yield White on Black, while on xterm(1) it would yield
Black on White.
ENVIRONMENT
rxvt sets the environment variables TERM, COLORTERM and
COLORFGBG. The environment variable WINDOWID is set to the X window
id number of the rxvt window and it also uses and sets the environment
variable DISPLAY to specify which display terminal to use. rxvt uses
the environment variables RXVTPATH and PATH to find XPM files.
