This option allows xterm to be
used as an input and output channel for an existing program and is sometimes
used in specialized applications. The option value specifies the last few
letters of the name of a pseudo-terminal to use in slave mode, plus the
number of the inherited file descriptor. If the option contains a ``/'' character,
that delimits the characters used for the pseudo-terminal name from the
file descriptor. Otherwise, exactly two characters are used from the option
for the pseudo-terminal name, the remainder is the file descriptor. Examples:
-S123/45
-Sab34
The following command line arguments are provided for compatibility with
older versions. They may not be supported in the next release as the X Toolkit
provides standard options that accomplish the same task.
- %geom
- This option
specifies the preferred size and position of the Tektronix window. It is
shorthand for specifying the ``*tekGeometry'' resource.
- #geom
- This option specifies
the preferred position of the icon window. It is shorthand for specifying
the ``*iconGeometry'' resource.
- -T string
- This option specifies the title for
xterm's windows. It is equivalent to -title.
- -n string
- This option specifies
the icon name for xterm's windows. It is shorthand for specifying the ``*iconName''
resource. Note that this is not the same as the toolkit option -name (see
below). The default icon name is the application name.
- -r
- This option indicates
that reverse video should be simulated by swapping the foreground and background
colors. It is equivalent to -rv.
- -w number
- This option specifies the width
in pixels of the border surrounding the window. It is equivalent to -borderwidth
or -bw.
The following standard X Toolkit command line arguments are commonly
used with xterm:
- -bd color
- This option specifies the color to use for the
border of the window. The default is ``black.''
- -bg color
- This option specifies
the color to use for the background of the window. The default is ``white.''
- -bw number
- This option specifies the width in pixels of the border surrounding
the window.
- -display display
- This option specifies the X server to contact;
see X(7x)
.
- -fg color
- This option specifies the color to use for displaying
text. The default is ``black.''
- -fn font
- This option specifies the font to be
used for displaying normal text. The default is fixed.
- -geometry geometry
- This option specifies the preferred size and position of the VT102 window;
see X(7x)
.
- -iconic
- This option indicates that xterm should ask the window
manager to start it as an icon rather than as the normal window.
- -name name
- This option specifies the application name under which resources are to
be obtained, rather than the default executable file name. Name should not
contain ``.'' or ``*'' characters.
- -rv
- This option indicates that reverse video should
be simulated by swapping the foreground and background colors.
- +rv
- Disable
the simulation of reverse video by swapping foreground and background colors.
- -title string
- This option specifies the window title string, which may be
displayed by window managers if the user so chooses. The default title is
the command line specified after the -e option, if any, otherwise the application
name.
- -xrm resourcestring
- This option specifies a resource string to be used.
This is especially useful for setting resources that do not have separate
command line options.
The program understands all of the core
X Toolkit resource names and classes. Application specific resources (e.g.,
"XTerm.NAME") follow:
- backarrowKeyIsErase (class BackarrowKeyIsErase)
- Tie
the VTxxx backarrowKey and ptyInitialErase resources together by setting
the DECBKM state according to whether the initial value of stty erase is
a backspace (8)
or delete (127) character. The default is ``false'', which disables
this feature.
- hold (class Hold)
- If true, xterm will not immediately destroy
its window when the shell command completes. It will wait until you use
the window manager to destroy/kill the window, or if you use the menu entries
that send a signal, e.g., HUP or KILL. You may scroll back, select text, etc.,
to perform most graphical operations. Resizing the display will lose data,
however, since this involves interaction with the shell which is no longer
running.
- hpFunctionKeys (class HpFunctionKeys)
- Specifies whether or not
HP Function Key escape codes should be generated for function keys instead
of standard escape sequences.
- iconGeometry (class IconGeometry)
- Specifies
the preferred size and position of the application when iconified. It is
not necessarily obeyed by all window managers.
- iconName (class IconName)
- Specifies the icon name. The default is the application name.
- messages (class
Messages)
- Specifies whether write access to the terminal is allowed initially.
See mesg(1)
. The default is ``true''.
- ptyHandshake (classPtyHandshake)
- If ``true'',
xterm will perform handshaking during initialization to ensure that the
parent and child processes update the utmp and stty state. Platforms with
newer pseudo-terminal interfaces do not require this feature; normally it
is not configured. The default is ``true''.
- ptyInitialErase (class PtyInitialErase)
- If ``true'', xterm will use the pseudo-terminal's sense of the stty erase value.
If ``false'', xterm will set the stty erase value to match its own configuration,
using the kb string from the termcap entry as a reference, if available.
In either case, the result is applied to the TERMCAP variable which xterm
sets. The default is ``false''.
- sameName (class SameName)
- If the value of this
resource is ``true'', xterm does not send title and icon name change requests
when the request would have no effect: the name is not changed. This has
the advantage of preventing flicker and the disadvantage of requiring an
extra round trip to the server to find out the previous value. In practice
this should never be a problem. The default is ``true''.
- sessionMgt (class SessionMgt)
- If the value of this resource is ``true'', xterm sets up session manager callbacks
for XtNdieCallback and XtNsaveCallback. The default is ``true''.
- sunFunctionKeys
(class SunFunctionKeys)
- Specifies whether or not Sun Function Key escape
codes should be generated for function keys instead of standard escape
sequences.
- sunKeyboard (class SunKeyboard)
- Specifies whether or not Sun/PC
keyboard layout should be assumed rather than DEC VT220. This causes the
keypad `+' to be mapped to `,'. and CTRL F1-F12 to F11-F20, depending on the setting
of the ctrlFKeys resource. so xterm emulates a DEC VT220 more accurately.
Otherwise (the default, with sunKeyboard set to ``false''), xterm uses PC-style
bindings for the function keys and keypad.
- termName (class TermName)
- Specifies
the terminal type name to be set in the TERM environment variable.
- title
(class Title)
- Specifies a string that may be used by the window manager
when displaying this application.
- ttyModes (class TtyModes)
- Specifies a
string containing terminal setting keywords and the characters to which
they may be bound. Allowable keywords include: intr, quit, erase, kill,
eof, eol, swtch, start, stop, brk, susp, dsusp, rprnt, flush, weras, lnext
and status. Control characters may be specified as ^char (e.g., ^c or ^u) and
^? may be used to indicate delete (127). Use ^- to denote undef. Use \034 to
represent ^\, since a literal backslash in an X resource escapes the next
character.
- This is very useful for overriding
- the default terminal settings
without having to do an stty every time an xterm is started. Note, however,
that the stty program on a given host may use different keywords; xterm's
table is builtin.
- useInsertMode (class UseInsertMode)
- Force use of insert
mode by adding appropriate entries to the TERMCAP environment variable.
This is useful if the system termcap is broken. The default is ``false.''
- utmpInhibit
(class UtmpInhibit)
- Specifies whether or not xterm should try to record
the user's terminal in the system utmp log file.
- waitForMap (class WaitForMap)
- Specifies whether or not xterm should wait for the initial window map before
starting the subprocess. The default is ``false.''
- zIconBeep (class ZIconBeep)
- Same as -ziconbeep command line argument. If the value of this resource is
non-zero, xterms that produce output while iconified will cause an XBell
sound at the given volume and have "***" prepended to their icon titles.
Most window managers will detect this change immediately, showing you which
window has the output. (A similar feature was in x10 xterm.) The default
is ``false.''
The following resources are specified as part of the vt100 widget
(class VT100): These are specified by patterns such as "XTerm.vt100.NAME":
- activeIcon (class ActiveIcon)
- Specifies whether or not active icon windows
are to be used when the xterm window is iconified, if this feature is compiled
into xterm. The active icon is a miniature representation of the content
of the window and will update as the content changes. Not all window managers
necessarily support application icon windows. Some window managers will
allow you to enter keystrokes into the active icon window. The default is
``false.''
- allowC1Printable (class AllowC1Printable)
- If true, overrides the
mapping of C1 controls (codes 128-159) to make them be treated as if they
were printable characters. Although this corresponds to no particular standard,
some users insist it is a VT100. The default is ``false.''
- allowSendEvents (class
AllowSendEvents)
- Specifies whether or not synthetic key and button events
(generated using the X protocol SendEvent request) should be interpreted
or discarded. The default is ``false'' meaning they are discarded. Note that
allowing such events creates a very large security hole. The default is
``false.''
- allowWindowOps (class AllowWindowOps)
- Specifies whether extended
window control sequences (as used in dtterm) for should be allowed. The
default is ``true.''
- answerbackString (class AnswerbackString)
- Specifies the
string that xterm sends in response to an ENQ (control/E) character from
the host. The default is a blank string, i.e., ``''. A hardware VT100 implements
this feature as a setup option.
- alwaysHighlight (class AlwaysHighlight)
- Specifies whether or not xterm should always display a highlighted text
cursor. By default (if this resource is false), a hollow text cursor is
displayed whenever the pointer moves out of the window or the window loses
the input focus. The default is ``false.''
- alwaysUseMods (class AlwaysUseMods)
- Override the numLock resource, telling xterm to use the Alt and Meta modifiers
as to construct parameters for function key sequences even if those modifiers
appear in the translations resource. The default is ``false.''
- appcursorDefault
(class AppcursorDefault)
- If ``true,'' the cursor keys are initially in application
mode. The default is ``false.''
- appkeypadDefault (class AppkeypadDefault)
- If
``true,'' the keypad keys are initially in application mode. The default is
``false.''
- autoWrap (class AutoWrap)
- Specifies whether or not auto-wraparound
should be enabled. The default is ``true.''
- awaitInput (class AwaitInput)
- Specifies
whether or not the xterm uses a 50 millisecond timeout to await input (i.e.,
to support the Xaw3d arrow scrollbar). The default is ``false.''
- backarrowKey
(class BackarrowKey)
- Specifies whether the backarrow key transmits a backspace
(8)
or delete (127) character. This corresponds to the DECBKM control sequence.
The default (backspace) is ``true.'' Pressing the control key toggles this behavior.
- background (class Background)
- Specifies the color to use for the background
of the window. The default is ``white.''
- bellSuppressTime (class BellSuppressTime)
- Number of milliseconds after a bell command is sent during which additional
bells will be suppressed. Default is 200. If set non-zero, additional bells
will also be suppressed until the server reports that processing of the
first bell has been completed; this feature is most useful with the visible
bell.
- boldColors (class ColorMode)
- Specifies whether to combine bold attribute
with colors like the IBM PC, i.e., map colors 0 through 7 to colors 8 through
15. These normally are the brighter versions of the first 8 colors, hence
bold. The default is ``true.''
- boldFont (class BoldFont)
- Specifies the name of
the bold font to use instead of overstriking. There is no default for this
resource.
- boldMode (class BoldMode)
- This specifies whether or not text with
the bold attribute should be overstruck to simulate bold fonts if the resolved
bold font is the same as the normal font. It may be desirable to disable
bold fonts when color is being used for the bold attribute. Note that xterm
has one bold font which you may set explicitly. It attempts to match a bold
font for the other font selections (font1 through font6). If the normal
and bold fonts are distinct, this resource has no effect. The default is
``true.''
- Although xterm attempts to match a bold font for other font selections,
- the font server may not cooperate. Since X11R6, bitmap fonts have been scaled.
The font server claims to provide the bold font that xterm requests, but
the result is not always readable. Xorg provides a feature which can be
used to suppressed the scaling. In the X server's configuration file (e.g.
/etc/X11/xorg.conf), you can add ":unscaled" to the end of the directory
specification for the "misc" fonts, which comprise the fixed-pitch fonts
that are used by xterm. For example
FontPath "/usr/lib/X11/fonts/misc/"
- would become
FontPath "/usr/lib/X11/fonts/misc/:unscaled"
- Depending on your configuration, the font server may have its own configuration
- file. The same ":unscaled" can be added to its configuration file at the
end of the directory specification for "misc".
- brokenLinuxOSC (class BrokenLinuxOSC)
- If true, xterm applies a workaround to ignore malformed control sequences
that a Linux script might send. Compare the palette control sequences documented
in console_codes with ECMA-48.
- brokenSelections (class BrokenSelections)
- If true, xterm in 8-bit mode will interpret STRING selections as carrying
text in the current locale's encoding. Normally STRING selections carry ISO-8859-1
encoded text. Setting this resource to ``true'' violates the ICCCM; it may,
however, be useful for interacting with some broken X clients. The default
is ``false.''
- brokenStringTerm (class BrokenStringTerm)
- provides a work-around
for some ISDN routers which start an application control string without
completing it. Set this to ``true'' if xterm appears to freeze when connecting.
The default is ``false.''
- c132 (class C132)
- Specifies whether or not the VT102
DECCOLM escape sequence should be honored. The default is ``false.''
- cutNewline
(class CutNewline)
- If ``false'', triple clicking to select a line does not
include the Newline at the end of the line. If ``true'', the Newline is selected.
The default is ``true.''
- cutToBeginningOfLine (class CutToBeginningOfLine)
- If
``false'', triple clicking to select a line selects only from the current word
forward. If ``true'', the entire line is selected. The default is ``true.''
- cacheDoublesize
(class CacheDoublesize)
- Specifies the maximum number of double-sized fonts
which are cached by xterm. The default (8)
may be too large for some X terminals
with limited memory. Set this to zero to disable doublesize fonts altogether.
- charClass (class CharClass)
- Specifies comma-separated lists of character
class bindings of the form [low-]high:value. These are used in determining
which sets of characters should be treated the same when doing cut and
paste. See the CHARACTER CLASSES section.
- cjkWidth (class CjkWidth)
- Specifies
whether xterm should follow the traditional East Asian width convention.
When turned on, characters with East Asian Ambiguous (A) category in UTR
11 have a column width of 2. You may have to set this option to ``true'' if
you have some old East Asian terminal based programs that assume that line-drawing
characters have a column width of 2. The default is ``false.''
- curses (class
Curses)
- Specifies whether or not the last column bug in more(1)
should
be worked around. See the -cu option for details. The default is ``false.''
- colorAttrMode
(class ColorAttrMode)
- Specifies whether ``colorBD'', ``colorBL'', ``colorUL'', and
``colorRV'' should override ANSI colors. If not, these are displayed only when
no ANSI colors have been set for the corresponding position. The default
is ``false.''
- colorMode (class ColorMode)
- Specifies whether or not recognition
of ANSI (ISO 6429) color change escape sequences should be enabled. The
default is ``true.''
- colorBDMode (class ColorAttrMode)
- Specifies whether characters
with the bold attribute should be displayed in color or as bold characters.
Note that setting colorMode off disables all colors, including bold. The
default is ``false.''
- colorBLMode (class ColorAttrMode)
- Specifies whether characters
with the blink attribute should be displayed in color. Note that setting
colorMode off disables all colors, including this. The default is ``false.''
- colorRVMode (class ColorAttrMode)
- Specifies whether characters with the
reverse attribute should be displayed in color. Note that setting colorMode
off disables all colors, including this. The default is ``false.''
- colorULMode
(class ColorAttrMode)
- Specifies whether characters with the underline attribute
should be displayed in color or as underlined characters. Note that setting
colorMode off disables all colors, including underlining. The default is
``false.''
- color0 (class Color0)
- color1 (class Color1)
- color2 (class Color2)
- color3 (class Color3)
- color4 (class Color4)
- color5 (class Color5)
- color6
(class Color6)
- color7 (class Color7)
- These specify the colors for the ISO
6429 extension. The defaults are, respectively, black, red3, green3, yellow3,
DodgerBlue1, magenta3, cyan3, and gray90. The default shades of color are
chosen to allow the colors 8-15 to be used as brighter versions.
- color8 (class
Color8)
- color9 (class Color9)
- color10 (class Color10)
- color11 (class Color11)
- color12 (class Color12)
- color13 (class Color13)
- color14 (class Color14)
- color15 (class Color15)
- These specify the colors for the ISO 6429 extension
if the bold attribute is also enabled. The default resource values are,
respectively, gray30, red, green, yellow, SteelBlue1, magenta, cyan, and
white.
- color16 (class Color16)
- through
- color255 (class Color255)
- These specify
the colors for the 256-color extension. The default resource values are for
colors 16 through 231 to make a 6x6x6 color cube, and colors 232 through
255 to make a grayscale ramp.
- colorBD (class ColorBD)
- This specifies the
color to use to display bold characters if the ``colorBDMode'' resource is
enabled. The default is ``XtDefaultForeground.''
- colorBL (class ColorBL)
- This
specifies the color to use to display blink characters if the ``colorBLMode''
resource is enabled. The default is ``XtDefaultForeground.''
- colorRV (class ColorRV)
- This specifies the color to use to display reverse characters if the ``colorRVMode''
resource is enabled. The default is ``XtDefaultForeground.''
- colorUL (class ColorUL)
- This specifies the color to use to display underlined characters if the
``colorULMode'' resource is enabled. The default is ``XtDefaultForeground.''
- ctrlFKeys
(class CtrlFKeys)
- In VT220 keyboard mode (see sunKeyboard resource), specifies
the amount by which to shift F1-F12 given a control modifier (CTRL). This
allows you to generate key symbols for F10-F20 on a Sun/PC keyboard. The
default is ``10'', which means that CTRL F1 generates the key symbol for F11.
- cursorBlink (class CursorBlink)
- Specifies whether to make the cursor blink.
The default is ``false.''
- cursorColor (class CursorColor)
- Specifies the color
to use for the text cursor. The default is ``black.''
- cursorOffTime (class CursorOffTime)
- Specifies the duration of the "off" part of the cursor blink cycle-time
in milliseconds. The default is 300.
- cursorOnTime (class CursorOnTime)
- Specifies
the duration of the "on" part of the cursor blink cycle-time, in milliseconds.
The default is 600.
- highlightColor (class HighlightColor)
- Specifies the
color to use for the background of selected or otherwise highlighted text.
If not specified, reverse video is used. The default is ``XtDefaultForeground.''
- decTerminalID (class DecTerminalID)
- Specifies the emulation level (100=VT100,
220=VT220, etc.), used to determine the type of response to a DA control
sequence. The default is 100.
- deleteIsDEL (class DeleteIsDEL)
- Specifies whether
the Delete key on the editing keypad should send DEL (127) or the VT220-style
Remove escape sequence. The default is ``false,'' for the latter.
- dynamicColors
(class DynamicColors)
- Specifies whether or not escape sequences to change
colors assigned to different attributes are recognized.
- eightBitControl
(class EightBitControl)
- Specifies whether or not control sequences sent
by the terminal should be eight-bit characters or escape sequences. The default
is ``false.''
- eightBitInput (class EightBitInput)
- If ``true'', Meta characters input
from the keyboard are presented as a single character with the eighth bit
turned on. The terminal is put into 8-bit mode. If ``false'', Meta characters
are converted into a two-character sequence with the character itself preceded
by ESC. The terminal is put into 7-bit mode. The metaSendsEscape resource
may override this. The default is ``true.''
- eightBitOutput (class EightBitOutput)
- Specifies whether or not eight-bit characters sent from the host should
be accepted as is or stripped when printed. The default is ``true,'' which means
that they are accepted as is.
- faceName (class FaceName)
- Specify the pattern
for fonts selected from the FreeType library if support for that library
was compiled into xterm. There is no default. If not specified, or if there
is no match for both normal and bold fonts, xterm uses the font and related
resources.
- faceSize (class FaceSize)
- Specify the pointsize for fonts selected
from the FreeType library if support for that library was compiled into
xterm. The default is ``14.''
- font (class Font)
- Specifies the name of the normal
font. The default is ``fixed.''
- See the discussion of the locale resource,
- which
describes how this font may be overridden.
- font1 (class Font1)
- Specifies
the name of the first alternative font.
- font2 (class Font2)
- Specifies the
name of the second alternative font.
- font3 (class Font3)
- Specifies the name
of the third alternative font.
- font4 (class Font4)
- Specifies the name of
the fourth alternative font.
- font5 (class Font5)
- Specifies the name of the
fifth alternative font.
- font6 (class Font6)
- Specifies the name of the sixth
alternative font.
- fontDoublesize (class FontDoublesize)
- Specifies whether
xterm should attempt to use font scaling to draw doublesize characters.
Some older font servers cannot do this properly, will return misleading
font metrics. The default is ``true''. If disabled, xterm will simulate doublesize
characters by drawing normal characters with spaces between them.
- forceBoxChars
(class Boolean)
- Specifies whether xterm should assume the normal and bold
fonts have VT100 line-drawing characters. If ``false'', xterm will check for
missing characters in the 1-31 cells and make line-drawing characters directly.
The default is ``false.''
- foreground (class Foreground)
- Specifies the color
to use for displaying text in the window. Setting the class name instead
of the instance name is an easy way to have everything that would normally
appear in the text color change color. The default is ``black.''
- freeBoldBox
(class Boolean)
- Specifies whether xterm should assume the bounding boxes
for normal and bold fonts are compatible. If ``false'', xterm compares them
and will reject choices of bold fonts that do not match the size of the
normal font. The default is ``false'', which means that the comparison is performed.
- geometry (class Geometry)
- Specifies the preferred size and position of
the VT102 window. There is no default for this resource.
- highlightSelection
(class HighlightSelection)
- If ``false'', selecting with the mouse highlights
all positions on the screen between the beginning of the selection and
the current position. If ``true'', xterm highlights only the positions that
contain text that can be selected. The default is ``false.''
- Depending on the
way your applications write to the screen, there may
- be trailing blanks
on a line. Xterm stores data as it is shown on the screen. Erasing the display
changes the internal state of each cell so it is not considered a blank
for the purpose of selection. Blanks written since the last erase are selectable.
If you do not wish to have trailing blanks in a selection, use the trimSelection
resource.
- hpLowerleftBugCompat (class HpLowerleftBugCompat)
- Specifies whether
to work around a bug in HP's xdb, which ignores termcap and always sends
ESC F to move to the lower left corner. ``true'' causes xterm to interpret ESC
F as a request to move to the lower left corner of the screen. The default
is ``false.''
- i18nSelections (class I18nSelections)
- If false, xterm will never
request the targets COMPOUND_TEXT or TEXT. The default is ``true.'' It may be
set to false in order to work around ICCCM violations by other X clients.
- iconBorderColor (class BorderColor)
- Specifies the border color for the
active icon window if this feature is compiled into xterm. Not all window
managers will make the icon border visible.
- iconBorderWidth (class BorderWidth)
- Specifies the border width for the active icon window if this feature is
compiled into xterm. The default is 0 (no border). Not all window managers
will make the border visible.
- iconFont (class IconFont)
- Specifies the font
for the miniature active icon window, if this feature is compiled into
xterm. The default is "nil2".
- internalBorder (class BorderWidth)
- Specifies
the number of pixels between the characters and the window border. The default
is 2.
- jumpScroll (class JumpScroll)
- Specifies whether or not jump scroll
should be used. The default is ``true.''
- keyboardDialect (class KeyboardDialect)
- Specifies the initial keyboard dialect, as well as the default value when
the terminal is reset. The value given is the same as the final character
in the control sequences which change character sets. The default is ``B'',
which corresponds to US ASCII.
- keymapNAME (class KeymapNAME)
- See the discussion
of the keymap() action.
- limitResize (class LimitResize)
- Limits resizing
of the screen via control sequence to a given multiple of the display dimensions.
The default is ``1''.
- locale (class Locale)
- Specifies how to use luit, an encoding
converter between UTF-8 and locale encodings. The resource value (ignoring
case) may be:
- true
- xterm will use the encoding specified by the users' LC_CTYPE
locale (i.e., LC_ALL, LC_CTYPE, or LANG variables) as far as possible. This
is realized by always enabling UTF-8 mode and invoking luit in non-UTF-8 locales.
- medium
- xterm will follow users' LC_CTYPE locale only for UTF-8, east Asian,
and Thai locales, where the encodings were not supported by conventional
8bit mode with changing fonts. For other locales, xterm will use conventional
8bit mode.
- no
- xterm will use conventional 8bit mode or UTF-8 mode according
to utf8 resource or -u8 option.
- Any other value, e.g., ``UTF-8'' or ``ISO8859-2'',
- is
assumed to be an encoding name; luit will be invoked to support the encoding.
The actual list of supported encodings depends on luit. The default is ``medium''.
- Regardless of your locale and encoding,
- you need an ISO-10646-1 font to display
the result. Your configuration may not include this font, or locale-support
by xterm may not be needed. At startup, xterm uses a mechanism equivalent
to the load-vt-fonts(utf8Fonts, Utf8Fonts) action to load font name subresources
of the VT100 widget. That is, resource patterns such as "*vt100.utf8Fonts.font"
will be loaded, and (if this resource is enabled), override the normal
fonts. If no subresources are found, the normal fonts such as "*vt100.font",
etc., are used. The resource files distributed with xterm use ISO-10646-1 fonts,
but do not rely on them unless you are using the locale mechanism.
- localeFilter
(class LocaleFilter)
- Specifies the file name for the encoding converter
from/to locale encodings and UTF-8 which is used with the -lc option or locale
resource. The help message shown by ``xterm -help'' lists the default value,
which depends on your system configuration.
- loginShell (class LoginShell)
- Specifies whether or not the shell to be run in the window should be started
as a login shell. The default is ``false.''
- marginBell (class MarginBell)
- Specifies
whether or not the bell should be run when the user types near the right
margin. The default is ``false.''
- metaSendsEscape (class MetaSendsEscape)
- If
``true'', Meta characters are converted into a two-character sequence with the
character itself preceded by ESC. This applies as well to function key control
sequences, unless xterm sees that Meta is used in your key translations.
If ``false'', Meta characters input from the keyboard are handled according
to the eightBitInput resource. The default is ``false.''
- modifyCursorKeys (class
ModifyCursorKeys)
- Tells how to handle the special case where control-, shift-,
alt- or meta-modifiers are used to add a parameter to the escape sequence
returned by a cursor-key. Set it to 0 to use the old/obsolete behavior. Set
it to 1 to prefix modified sequences with CSI. Set it to 2 to force the
modifier to be the second parameter. Set it to 3 to mark the sequence with
a '>' to hint that it is private. The default is ``2''.
- multiClickTime (class MultiClickTime)
- Specifies the maximum time in milliseconds between multi-click select events.
The default is 250 milliseconds.
- multiScroll (class MultiScroll)
- Specifies
whether or not scrolling should be done asynchronously. The default is ``false.''
- nMarginBell (class Column)
- Specifies the number of characters from the
right margin at which the margin bell should be rung, when enabled.
- numLock
(class NumLock)
- If ``true'', xterm checks if NumLock is used as a modifier
(see xmodmap(1)
). If so, this modifier is used to simplify the logic when
implementing special NumLock for the sunKeyboard resource. Also (when sunKeyboard
is false), similar logic is used to find the modifier associated with the
left and right Alt keys. The default is ``true.''
- oldXtermFKeys (class OldXtermFKeys)
- If ``true'', xterm will use old-style control sequences for function keys F1
to F4, for compatibility with X Consortium xterm. Otherwise, it uses the
VT100-style codes for PF1 to PF4. The default is ``false.''
- pointerColor (class
PointerColor)
- Specifies the foreground color of the pointer. The default
is ``XtDefaultForeground.''
- pointerColorBackground (class PointerColorBackground)
- Specifies the background color of the pointer. The default is ``XtDefaultBackground.''
- pointerShape (class Cursor)
- Specifies the name of the shape of the pointer.
The default is ``xterm.''
- popOnBell (class PopOnBell)
- Specifies whether the
window whould be raised when Control-G is received. The default is ``false.''
- printAttributes (class PrintAttributes)
- Specifies whether to print graphic
attributes along with the text. A real DEC VTxxx terminal will print the
underline, highlighting codes but your printer may not handle these. A ``0''
disables the attributes. A ``1'' prints the normal set of attributes (bold,
underline, inverse and blink) as VT100-style control sequences. A ``2'' prints
ANSI color attributes as well. The default is ``1.''
- printerAutoClose (class
PrinterAutoClose)
- If ``true'', xterm will close the printer (a pipe) when the
application switches the printer offline with a Media Copy command. The
default is ``false.''
- printerCommand (class PrinterCommand)
- Specifies a shell
command to which xterm will open a pipe when the first MC (Media Copy)
command is initiated. The default is ``lpr.'' If the resource value is given
as a blank string, the printer is disabled.
- printerControlMode (class PrinterControlMode)
- Specifies the printer control mode. A ``1'' selects autoprint mode, which causes
xterm to print a line from the screen when you move the cursor off that
line with a line feed, form feed or vertical tab character, or an autowrap
occurs. Autoprint mode is overridden by printer controller mode (a ``2''), which
causes all of the output to be directed to the printer. The default is ``0.''
- printerExtent (class PrinterExtent)
- Controls whether a print page function
will print the entire page (true), or only the the portion within the scrolling
margins (false). The default is ``false.''
- printerFormFeed (class PrinterFormFeed)
- Controls whether a form feed is sent to the printer at the end of a print
page function. The default is ``false.''
- resizeGravity (class ResizeGravity)
- Affects the behavior when the window is resized to be taller or shorter.
NorthWest specifies that the top line of text on the screen stay fixed.
If the window is made shorter, lines are dropped from the bottom; if the
window is made taller, blank lines are added at the bottom. This is compatible
with the behavior in R4. SouthWest (the default) specifies that the bottom
line of text on the screen stay fixed. If the window is made taller, additional
saved lines will be scrolled down onto the screen; if the window is made
shorter, lines will be scrolled off the top of the screen, and the top
saved lines will be dropped.
- reverseVideo (class ReverseVideo)
- Specifies
whether or not reverse video should be simulated. The default is ``false.''
- reverseWrap
(class ReverseWrap)
- Specifies whether or not reverse-wraparound should be
enabled. The default is ``false.''
- rightScrollBar (class RightScrollBar)
- Specifies
whether or not the scrollbar should be displayed on the right rather than
the left. The default is ``false.''
- saveLines (class SaveLines)
- Specifies the
number of lines to save beyond the top of the screen when a scrollbar is
turned on. The default is 64.
- scrollBar (class ScrollBar)
- Specifies whether
or not the scrollbar should be displayed. The default is ``false.''
- scrollKey
(class ScrollCond)
- Specifies whether or not pressing a key should automatically
cause the scrollbar to go to the bottom of the scrolling region. The default
is ``false.''
- scrollLines (class ScrollLines)
- Specifies the number of lines
that the scroll-back and scroll-forw actions should use as a default. The
default value is 1.
- scrollTtyOutput (class ScrollCond)
- Specifies whether
or not output to the terminal should automatically cause the scrollbar
to go to the bottom of the scrolling region. The default is ``true.''
- shiftFonts
(class ShiftFonts)
- Specifies whether to enable the actions larger-vt-font()
and smaller-vt-font(), which are normally bound to the shifted KP_Add and
KP_Subtract. The default is ``true.''
- signalInhibit (class SignalInhibit)
- Specifies
whether or not the entries in the ``Main Options'' menu for sending signals
to xterm should be disallowed. The default is ``false.''
- tekGeometry (class Geometry)
- Specifies the preferred size and position of the Tektronix window. There
is no default for this resource.
- tekInhibit (class TekInhibit)
- Specifies
whether or not the escape sequence to enter Tektronix mode should be ignored.
The default is ``false.''
- tekSmall (class TekSmall)
- Specifies whether or not
the Tektronix mode window should start in its smallest size if no explicit
geometry is given. This is useful when running xterm on displays with small
screens. The default is ``false.''
- tekStartup (class TekStartup)
- Specifies whether
or not xterm should start up in Tektronix mode. The default is ``false.''
- titeInhibit
(class TiteInhibit)
- Specifies whether or not xterm should remove ti and
te termcap entries (used to switch between alternate screens on startup
of many screen-oriented programs) from the TERMCAP string. If set, xterm
also ignores the escape sequence to switch to the alternate screen. Xterm
supports terminfo in a different way, supporting composite control sequences
(also known as private modes) 1047, 1048 and 1049 which have the same effect
as the original 47 control sequence. The default for this resource is ``false.''
- tiXtraScroll (class TiXtraScroll)
- Specifies whether xterm should scroll
to a new page when processing the ti termcap entry, i.e., the private modes
47, 1047 or 1049. This is only in effect if titeInhibit is ``true'', because
the intent of this option is to provide a picture of the full-screen application's
display on the scrollback without wiping out the text that would be shown
before the application was initialized. The default for this resource is
``false.''
- translations (class Translations)
- Specifies the key and button bindings
for menus, selections, ``programmed strings,'' etc. See the ACTIONS section.
- trimSelection (class TrimSelection)
- If you set highlightSelection, you
can see the text which is selected, including any trailing spaces. Clearing
the screen (or a line) resets it to a state containing no spaces. Some lines
may contain trailing spaces when an application writes them to the screen.
However, you may not wish to paste lines with trailing spaces. If this resource
is true, xterm will trim trailing spaces from text which is selected. It
does not affect spaces which result in a wrapped line, nor will it trim
the trailing newline from your selection. The default is ``false.''
- underLine
(class UnderLine)
- This specifies whether or not text with the underline
attribute should be underlined. It may be desirable to disable underlining
when color is being used for the underline attribute. The default is ``true.''
- utf8 (class Utf8)
- This specifies whether xterm will run in UTF-8 mode. If
you set this resource, xterm also sets the wideChars resource as a side-effect.
When set via a resource, xterm cannot be switched via control sequences
out of UTF-8 mode. The default is ``0'' (off). Any other value will turn on UTF-8
mode. See the locale resource for non-UTF-8 locales.
- utf8Fonts (class Utf8Fonts)
- See the discussion of the locale resource.
- veryBoldColors (class VeryBoldColors)
- Specifies whether to combine video attributes with colors specified by
colorBD, colorBL and colorUL. The resource value is the sum of values for
each attribute: 2 for underline, 4 for bold and 8 for blink. The default
is ``0.''
- visualBell (class VisualBell)
- Specifies whether or not a visible bell
(i.e., flashing) should be used instead of an audible bell when Control-G
is received. The default is ``false.''
- visualBellDelay (class VisualBellDelay)
- Number of milliseconds to delay when displaying a visual bell. Default is
100. If set to zero, no visual bell is displayed. This is useful for very
slow displays, e.g., an LCD display on a laptop.
- vt100Graphics (class VT100Graphics)
- This specifies whether xterm will interpret VT100 graphic character escape
sequences while in UTF-8 mode. The default is ``true'', to provide support for
various legacy applications.
- wideBoldFont (class WideBoldFont)
- This option
specifies the font to be used for displaying bold wide text. By default,
it will attempt to use a font twice as wide as the font that will be used
to draw bold text. If no doublewidth font is found, it will improvise, by
stretching the bold font.
- wideChars (class WideChars)
- Specifies if xterm
should respond to control sequences that process 16-bit characters. The default
is ``false.''
- wideFont (class WideFont)
- This option specifies the font to be
used for displaying wide text. By default, it will attempt to use a font
twice as wide as the font that will be used to draw normal text. If no doublewidth
font is found, it will improvise, by stretching the normal font.
- ximFont
(class XimFont)
- This option specifies the font to be used for displaying
the preedit string in the "OverTheSpot" input method.
- In "OverTheSpot" preedit
type, the preedit (preconversion)
- string is displayed at the position of
the cursor. It is the XIM server's responsibility to display the preedit
string. The XIM client must inform the XIM server of the cursor position.
For best results, the preedit string must be displayed with a proper font.
Therefore, xterm informs the XIM server of the proper font. The font is
be supplied by a "fontset", whose default value is "*". This matches every
font, the X library automatically chooses fonts with proper charsets. The
ximFont resource is provided to override this default font setting.
The
following resources are specified as part of the tek4014 widget (class
Tek4014). These are specified by patterns such as "XTerm.tek4014.NAME":

EOT. The default is ``none.''
- height (class Height)
- Specifies the height of the
Tektronix window in pixels.
- initialFont (class InitialFont)

The following resources are useful
when specified for the Athena Scrollbar widget:
- thickness (class Thickness)
- Specifies the width in pixels of the scrollbar.
- background (class Background)
- Specifies the color to use for the background of the scrollbar.
- foreground
(class Foreground)
- Specifies the color to use for the foreground of the
scrollbar. The ``thumb'' of the scrollbar is a simple checkerboard pattern alternating
pixels for foreground and background color.
Once the VT102
window is created, xterm allows you to select text and copy it within the
same or other windows.
The selection functions are invoked when the pointer
buttons are used with no modifiers, and when they are used with the ``shift''
key. The assignment of the functions described below to keys and buttons
may be changed through the resource database; see ACTIONS below.
Pointer
button one (usually left) is used to save text into the cut buffer. Move
the cursor to beginning of the text, and then hold the button down while
moving the cursor to the end of the region and releasing the button. The
selected text is highlighted and is saved in the global cut buffer and
made the PRIMARY selection when the button is released. Double-clicking selects
by words. Triple-clicking selects by lines. Quadruple-clicking goes back to
characters, etc. Multiple-click is determined by the time from button up
to button down, so you can change the selection unit in the middle of a
selection. Logical words and lines selected by double- or triple-clicking
may wrap across more than one screen line if lines were wrapped by xterm
itself rather than by the application running in the window. If the key/button
bindings specify that an X selection is to be made, xterm will leave the
selected text highlighted for as long as it is the selection owner.
Pointer
button two (usually middle) `types' (pastes) the text from the PRIMARY selection,
if any, otherwise from the cut buffer, inserting it as keyboard input.
Pointer button three (usually right) extends the current selection. (Without
loss of generality, you can swap ``right'' and ``left'' everywhere in the rest
of this paragraph.) If pressed while closer to the right edge of the selection
than the left, it extends/contracts the right edge of the selection. If
you contract the selection past the left edge of the selection, xterm assumes
you really meant the left edge, restores the original selection, then extends/contracts
the left edge of the selection. Extension starts in the selection unit mode
that the last selection or extension was performed in; you can multiple-click
to cycle through them.
By cutting and pasting pieces of text without trailing
new lines, you can take text from several places in different windows and
form a command to the shell, for example, or take output from a program
and insert it into your favorite editor. Since the cut buffer is globally
shared among different applications, you should regard it as a `file' whose
contents you know. The terminal emulator and other text programs should
be treating it as if it were a text file, i.e., the text is delimited by
new lines.
The scroll region displays the position and amount of text currently
showing in the window (highlighted) relative to the amount of text actually
saved. As more text is saved (up to the maximum), the size of the highlighted
area decreases.
Clicking button one with the pointer in the scroll region
moves the adjacent line to the top of the display window.
Clicking button
three moves the top line of the display window down to the pointer position.
Clicking button two moves the display to a position in the saved text
that corresponds to the pointer's position in the scrollbar.
Unlike the
VT102 window, the Tektronix window does not allow the copying of text. It
does allow Tektronix GIN mode, and in this mode the cursor will change
from an arrow to a cross. Pressing any key will send that key and the current
coordinate of the cross cursor. Pressing button one, two, or three will
return the letters `l', `m', and `r', respectively. If the `shift' key is pressed
when a pointer button is pressed, the corresponding upper case letter is
sent. To distinguish a pointer button from a key, the high bit of the character
is set (but this is bit is normally stripped unless the terminal mode is
RAW; see tty(4)
for details).
Xterm has four menus, named mainMenu,
vtMenu, fontMenu, and tekMenu. Each menu pops up under the correct combinations
of key and button presses. Most menus are divided into two section, separated
by a horizontal line. The top portion contains various modes that can be
altered. A check mark appears next to a mode that is currently active. Selecting
one of these modes toggles its state. The bottom portion of the menu are
command entries; selecting one of these performs the indicated function.
The xterm menu pops up when the ``control'' key and pointer button one are
pressed in a window. The mainMenu contains items that apply to both the
VT102 and Tektronix windows. The Secure Keyboard mode is be used when typing
in passwords or other sensitive data in an unsecure environment; see SECURITY
below. Notable entries in the command section of the menu are the Continue,
Suspend, Interrupt, Hangup, Terminate and Kill which sends the SIGCONT,
SIGTSTP, SIGINT, SIGHUP, SIGTERM and SIGKILL signals, respectively, to
the process group of the process running under xterm (usually the shell).
The Continue function is especially useful if the user has accidentally
typed CTRL-Z, suspending the process.
The vtMenu sets various modes in the
VT102 emulation, and is popped up when the ``control'' key and pointer button
two are pressed in the VT102 window. In the command section of this menu,
the soft reset entry will reset scroll regions. This can be convenient when
some program has left the scroll regions set incorrectly (often a problem
when using VMS or TOPS-20). The full reset entry will clear the screen, reset
tabs to every eight columns, and reset the terminal modes (such as wrap
and smooth scroll) to their initial states just after xterm has finished
processing the command line options.
The fontMenu sets the font used in
the VT102 window. In addition to the default font and a number of alternatives
that are set with resources, the menu offers the font last specified by
the Set Font escape sequence (see the document Xterm Control Sequences)
and the current selection as a font name (if the PRIMARY selection is owned).
The tekMenu sets various modes in the Tektronix emulation, and is popped
up when the ``control'' key and pointer button two are pressed in the Tektronix
window. The current font size is checked in the modes section of the menu.
The PAGE entry in the command section clears the Tektronix window.
X environments differ in their security consciousness. Most servers, run
under xdm, are capable of using a ``magic cookie'' authorization scheme that
can provide a reasonable level of security for many people. If your server
is only using a host-based mechanism to control access to the server (see
xhost(1)
), then if you enable access for a host and other users are also
permitted to run clients on that same host, there is every possibility
that someone can run an application that will use the basic services of
the X protocol to snoop on your activities, potentially capturing a transcript
of everything you type at the keyboard. This is of particular concern when
you want to type in a password or other sensitive data. The best solution
to this problem is to use a better authorization mechanism that host-based
control, but a simple mechanism exists for protecting keyboard input in
xterm.
The xterm menu (see MENUS above) contains a Secure Keyboard entry
which, when enabled, ensures that all keyboard input is directed only to
xterm (using the GrabKeyboard protocol request). When an application prompts
you for a password (or other sensitive data), you can enable Secure Keyboard
using the menu, type in the data, and then disable Secure Keyboard using
the menu again. Only one X client at a time can secure the keyboard, so
when you attempt to enable Secure Keyboard it may fail. In this case, the
bell will sound. If the Secure Keyboard succeeds, the foreground and background
colors will be exchanged (as if you selected the Reverse Video entry in
the Modes menu); they will be exchanged again when you exit secure mode.
If the colors do not switch, then you should be very suspicious that you
are being spoofed. If the application you are running displays a prompt
before asking for the password, it is safest to enter secure mode before
the prompt gets displayed, and to make sure that the prompt gets displayed
correctly (in the new colors), to minimize the probability of spoofing.
You can also bring up the menu again and make sure that a check mark appears
next to the entry.
Secure Keyboard mode will be disabled automatically
if your xterm window becomes iconified (or otherwise unmapped), or if you
start up a reparenting window manager (that places a title bar or other
decoration around the window) while in Secure Keyboard mode. (This is a
feature of the X protocol not easily overcome.) When this happens, the
foreground and background colors will be switched back and the bell will
sound in warning.
Clicking the middle mouse button twice
in rapid succession will cause all characters of the same class (e.g., letters,
white space, punctuation) to be selected. Since different people have different
preferences for what should be selected (for example, should filenames
be selected as a whole or only the separate subnames), the default mapping
can be overridden through the use of the charClass (class CharClass) resource.
This resource is a series of comma-separated of range:value pairs. The range
is either a single number or low-high in the range of 0 to 65535, corresponding
to the code for the character or characters to be set. The value is arbitrary,
although the default table uses the character number of the first character
occurring in the set. When not in UTF-8 mode, only the first 256 bytes of
this table will be used.
The default table starts as follows -
static int charClass[256] = {
/* NUL SOH STX ETX EOT ENQ ACK BEL */
32, 1, 1, 1, 1, 1, 1, 1,

For example, the string ``33:48,37:48,45-47:48,38:48'' indicates that the exclamation
mark, percent sign, dash, period, slash, and ampersand characters should
be treated the same way as characters and numbers. This is useful for cutting
and pasting electronic mailing addresses and filenames.
It is possible
to rebind keys (or sequences of keys) to arbitrary strings for input, by
changing the translations for the vt100 or tek4014 widgets. Changing the
translations for events other than key and button events is not expected,
and will cause unpredictable behavior. The following actions are provided
for using within the vt100 or tek4014 translations resources:
- allow-send-events(on/off/toggle)
- This action set or toggles the allowSendEvents resource and is also invoked
by the allowsends entry in mainMenu.
- bell([percent])
- This action rings the
keyboard bell at the specified percentage above or below the base volume.
- clear-saved-lines()
- This action does hard-reset() (see below) and also clears
the history of lines saved off the top of the screen. It is also invoked
from the clearsavedlines entry in vtMenu. The effect is identical to a hardware
reset (RIS) control sequence.
- create-menu(m/v/f/t)
- This action creates one
of the menus used by xterm, if it has not been previously created. The parameter
values are the menu names: mainMenu, vtMenu, fontMenu, tekMenu, respectively.
- deiconify()
- Changes the window state back to normal, if it was iconified.
- delete-is-del()
- This action toggles the state of the deleteIsDEL resource.
- dired-button()
- Handles a button event (other than press and release) by
echoing the event's position (i.e., character line and column) in the following
format:
^X ESC G <line+' '> <col+' '>
- iconify()
- Iconifies the window.
- hard-reset()
- This action resets the scrolling region, tabs, window size, and cursor
keys and clears the screen. It is also invoked from the hardreset entry
in vtMenu.
- ignore()
- This action ignores the event but checks for special
pointer position escape sequences.
- insert()
- This action inserts the character
or string associated with the key that was pressed.
- insert-eight-bit()
- This
action inserts an eight-bit (Meta) version of the character or string associated
with the key that was pressed. The exact action depends on the value of
the metaSendsEscape and the eightBitInput resources.
- insert-selection(sourcename
[, ...])
- This action inserts the string found in the selection or cutbuffer
indicated by sourcename. Sources are checked in the order given (case is
significant) until one is found. Commonly-used selections include: PRIMARY,
SECONDARY, and CLIPBOARD. Cut buffers are typically named CUT_BUFFER0 through
CUT_BUFFER7.
- insert-seven-bit()
- This action is a synonym for insert()
- interpret(control-sequence)
- Interpret the given control sequence locally, i.e., without passing it to
the host. This works by inserting the control sequence at the front of the
input buffer. Use "\" to escape octal digits in the string. Xt does not allow
you to put a null character (i.e., "\000") in the string.
- keymap(name)
- This
action dynamically defines a new translation table whose resource name
is name with the suffix Keymap (case is significant). The name None restores
the original translation table.
- larger-vt-font()
- Set the font to the next
larger one, based on the font dimensions. See also set-vt-font().
- load-vt-fonts(name[,class])
- Load fontnames from the given subresource name and class. That is, load
the "*VT100.name.font", resource as "*VT100.font" etc. If no name is given,
the original set of fontnames is restored.
- Unlike set-vt-font(), this does
not affect the escape- and select-fonts,
- since those are not based on resource
values. It does affect the fonts loosely organized under the ``Default'' menu
entry: font, boldFont, wideFont and wideBoldFont.

- Resizes the
window to fill the screen.
- meta-sends-escape()
- This action toggles the state

- This action prints the window and
is also invoked by the print entry in mainMenu.
- print-redir()
- This action
toggles the printerControlMode between 0 and 2. The corresponding popup
menu entry is useful for switching the printer off if you happen to change
your mind after deciding to print random binary files on the terminal.
- quit()
- This action sends a SIGHUP to the subprogram and exits. It is also invoked
by the quit entry in mainMenu.
- redraw()
- This action redraws the window and
is also invoked by the redraw entry in mainMenu.
- restore()
- Restores the
window to the size before it was last maximized.
- scroll-back(count [,units
[,mouse] ])

had previously scrolled off the top of the screen is now visible.
- The count
argument
- indicates the number of units (which may be page, halfpage, pixel,
or line) by which to scroll.
- An adjustment can be specified for these values
by appending a "+" or "-"
- sign followed by a number, e.g., page-2 to specify
2 lines less than a page.
- If the third parameter mouse is given, the action
is ignored when
- mouse reporting is enabled.
- scroll-forw(count [,units [,mouse]
])
- This action scrolls is similar to scroll-back except that it scrolls
the other direction.
- secure()
- This action toggles the Secure Keyboard mode
described in the section named SECURITY, and is invoked from the securekbd

at the current pointer location. See the section on POINTER USAGE for information
on making selections.
- send-signal(signame)
- This action sends the signal named
by signame to the xterm subprocess (the shell or program specified with
the -e command line option) and is also invoked by the suspend, continue,
interrupt, hangup, terminate, and kill entries in mainMenu. Allowable signal
names are (case is not significant): tstp (if supported by the operating
system), suspend (same as tstp), cont (if supported by the operating system),
int, hup, term, quit, alrm, alarm (same as alrm) and kill.

The Xterm Control Sequences document lists
the control sequences which an application can send xterm to make it perform
various operations. Most of these operations are standardized, from either
the DEC or Tektronix terminals, or from more widely used standards such
as ISO 6429.
Xterm sets the environment variables ``TERM'' for
the window you have created. It also uses and sets the environment variable
``DISPLAY'' to specify which bit map display terminal to use. The environment
variable ``WINDOWID'' is set to the X window id number of the xterm window.
Depending on your system configuration, xterm may also set the following:
- COLUMNS
- the width of the xterm in characters (cf: "stty columns").
- HOME
- when xterm is configured to update utmp.
- LINES
- the height of the xterm in
characters (cf: "stty rows").
- LOGNAME
- when xterm is configured to update
utmp.
- SHELL
- when xterm is configured to update utmp.
- TERMCAP
- the contents
of the termcap entry corresponding to $TERM, with lines and columns values
substituted for the actual size window you have created.
- TERMINFO
- may be
defined to a nonstandard location in the configure script.
The actual
pathnames given may differ on your system.
- /etc/utmp
- the system logfile,
which records user logins.
- /etc/wtmp
- the system logfile, which records user
logins and logouts.
- /etc/X11/app-defaults/XTerm
- the xterm default application
resources.
- /etc/X11/app-defaults/XTerm-color
- the xterm color application resources.
If your display supports color, use this *customization: -color in your
.Xdefaults file to automatically turn on color in xterm and similar applications.
Most of the fatal error messages from xterm use the following
format: xterm: Error XXX, errno YYY: ZZZ
The XXX codes (which are used
by xterm as its exit-code) are listed below, with a brief explanation.
- is
used for miscellaneous errors, usually accompanied by a specific message,

Large pastes do not work on some
systems. This is not a bug in xterm; it is a bug in the pseudo terminal
driver of those systems. xterm feeds large pastes to the pty only as fast
as the pty will accept data, but some pty drivers do not return enough
information to know if the write has succeeded.
Many of the options are
not resettable after xterm starts.
This program still needs to be rewritten.
It should be split into very modular sections, with the various emulators
being completely separate widgets that do not know about each other. Ideally,
