## NAME

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

## SYNOPSIS

rxvt [options] [-e command [ args ]]

## DESCRIPTION

rxvt, version 2.6.1, 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.

-display displayname
  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.

-geometry geom
  Window geometry (-g still respected); resource geometry.

-rv|+rv
  Turn on/off simulated reverse video; resource reverseVideo.

-ip|+ip
  Turn on/off inheriting parent window's pixmap; resource inheritPixmap.

-bg colour
  Window background colour; resource background.

-fg colour
  Window foreground colour; resource foreground.

-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.

-cr colour
  The cursor colour; resource cursorColor.

-pr colour
  The mouse pointer colour; resource pointerColor.

-bd colour
  The colour of the border between the xterm scrollbar and the text; resource borderColor.

-grk mode
  Greek keyboard translation; iso: ISO-8859 mapping. ibm: IBM-437 mapping; resource greek_keyboard.

-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
  Inhibit/enable writing a utmp entry; resource utmpInhibit.

  Start iconified, if the window manager supports that option.

-sl number
  Save number lines in the scrollback buffer; resource saveLines.

-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 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).

-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.

## RESOURCES (available also as long-options)

If compiled with internal Xresources support (i.e. rxvt -h lists .Xdefaults) then 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 if ~/.Xdefaults does not exist. 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: boolean
  True: simulate reverse video by foreground and background colours; option -rv, False: regular screen colours [default]; option +rv. See note in COLORS AND GRAPHICS section.

inheritPixmap: boolean
  True: make the background inherit the parent window's pixmap, giving artificial transparency. False: do not inherit the parent window's pixmap.

scrollColor: colour
  Use the specified colour for the scrollbar [default #B2B2B2].

troughColor: colour
  Use the specified colour for the scrollbar's trough area [default #969696]. Only relevant for normal (non XTerm/NeXT) scrollbar.

backgroundPixmap: file[;geom]
  Use the specified XPM file (note the `.xpm' extension is optional) for the background and also optionally specify its scaling with a geometry string WxH+X+Y, in which "W" / "H" specify the horizontal/vertical scale (percent) and "X" / "Y" locate the image centre (percent). A scale of 0 displays the image with tiling. A scale of 1 displays the image without any scaling. A scale of 2 to 9 specifies an integer number of images in that direction. No image will be magnified beyond 10 times its original size. The maximum permitted scale is 1000. [default 0x0+50+50]

menu: file[;tag]
  Read in the specified menu file (note the `.menu' extension is optional) and also optionally specify a starting tag to find. See the reference documentation for details on the syntax for the menuBar.

path: path
  Specify the colon-delimited search path for finding files (XPM and menus), in addition to the paths specified by the RXVTPATH and PATH environment variables.

font: fontname
  Select the main text font used [default 7x14]; option -fn.

fontn: fontname
  Specify the alternative font n. The default font values:

  font: | 7x14
  font1: | 6x10
  font2: | 6x13
  font3: | 8x13
  font4: | 9x15

boldFont: fontname
  Specify the name of the bold font to use if colorBD has not been specified and it is not possible to map the default foreground colour to colour 8-15 [default NONE]. This font must be the same height and width as the normal font; option -fb.

mfont: fontname
  Select the main multiple-character text font used [default k14]; option -fk.

mfontn: fontname
  Specify the alternative multiple-character font n. If compiled for multiple-character fonts, the Roman and multiple-character font sizes should match.

multichar_encoding: mode
  Set the encoding mode to be used when multicharacter encoding is received; eucj: EUC Japanese encoding [default for Kanji]. sjis: Shift JIS encoding. big5: BIG5 encoding. gb: GB encoding; option -km.

greek_keyboard: mode
  Set the Greek keyboard translation mode to be used; iso: ISO-8859 mapping (elot-928) [default]. ibm: IBM-437 mapping (DOS codepage 737); option -grk. Use Mode_switch to toggle keyboard input. For more details, see the distributed file README.greek.

selectstyle: text
  Set mouse selection style to old which is 2.20, oldword which is xterm style with 2.20 old word selection, or anything else which gives xterm style selection.

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.

scrollBar: boolean
  True: enable the scrollbar [default]; option -sb. False: disable the scrollbar; option +sb. Note that the scrollbar type (with/without arrows) is compile-time selected.

smallfont_key: keysym
  If enabled, use Alt-keysym to toggle to a smaller font [default Alt-<]

bigfont_key: keysym
  If enabled, use Alt-keysym to toggle to a bigger font [default Alt->]

saveLines: number
  Save number lines in the scrollback buffer [default 64]; option -sl.

termName: termname
  Specifies the terminal type name to be set in the TERM environment variable; option -tn.

backspacekey: string
  The string to send when the backspace key is pressed. If set to DEC or unset it will send Delete (code 127) or, if shifted, Backspace (code 8) - which can be reversed with the appropriate DEC private mode escape sequence.

deletekey: string
  The string to send when the delete key (not the keypad delete key) is pressed. If unset it will send the sequence traditionally associated with the Execute key.

cutchars: string
  The characters used as delimiters for double-click word selection. The built-in default:
  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.

## FILES

/etc/utmp
  System file for login records.

/usr/lib/X11/rgb.txt
  Color names.

## SEE ALSO

See rxvtRef.html rxvtRef.txt for detailed information on recognized escape sequences and menuBar syntax, etc.

## BUGS

Check the BUGS file for an up-to-date list.

Cursor change support is not yet implemented.

Click-and-drag doesn't work with X11 mouse report overriding.

Graphics support is fairly crude.
