xterm -
terminal emulator for X
xterm [-toolkitoption ...] [-option ...]
The
xterm program is a terminal emulator for the X Window System. It provides
DEC VT102/VT220 (VTxxx) and Tektronix 4014 compatible terminals for programs
that can't use the window system directly. If the underlying operating system
supports terminal resizing capabilities (for example, the SIGWINCH signal
in systems derived from 4.3bsd), xterm will use the facilities to notify
programs running in the window whenever it is resized.
The VTxxx and Tektronix
4014 terminals each have their own window so that you can edit text in
one and look at graphics in the other at the same time. To maintain the
correct aspect ratio (height/width), Tektronix graphics will be restricted
to the largest box with a 4014's aspect ratio that will fit in the window.
This box is located in the upper left area of the window.
Although both
windows may be displayed at the same time, one of them is considered the
``active'' window for receiving keyboard input and terminal output. This is
the window that contains the text cursor. The active window can be chosen
through escape sequences, the ``VT Options'' menu in the VTxxx window, and
the ``Tek Options'' menu in the 4014 window.
The VT102 emulation is
fairly complete, but does not support autorepeat. Double-size characters
are displayed properly if your font server supports scalable fonts. Blinking
characters are partially implemented; the emulation is functional but does
not have the appearance of a real VT102. The VT220 emulation does not support
soft fonts, it is otherwise complete. Termcap(5)
entries that work with
xterm include ``xterm,'' ``vt102,'' ``vt100'' and ``ansi,'' and xterm automatically searches
the termcap file in this order for these entries and then sets the ``TERM''
and the ``TERMCAP'' environment variables. You may also use ``vt220,'' but must
set the terminal emulation level with the decTerminalID resource.
Many of
the special xterm features may be modified under program control through
a set of escape sequences different from the standard VT102 escape sequences.
(See the Xterm Control Sequences document.)
The Tektronix 4014 emulation
is also fairly good. It supports 12-bit graphics addressing, scaled to the
window size. Four different font sizes and five different lines types are
supported. There is no write-through or defocused mode support. The Tektronix
text and graphics commands are recorded internally by xterm and may be
written to a file by sending the COPY escape sequence (or through the Tektronix
menu; see below). The name of the file will be ``COPYyyyy-MM-dd.hh:mm:ss'', where
yy, MM, dd, hh, mm and ss are the year, month, day, hour, minute and second
when the COPY was performed (the file is created in the directory xterm
is started in, or the home directory for a login xterm).
Not all of the
features described in this manual are necessarily available in this version
of xterm. Some (e.g., the non-VT220 extensions) are available only if they
were compiled in, though the most commonly-used are in the default configuration.
Xterm automatically highlights the text cursor when the pointer
enters the window (selected) and unhighlights it when the pointer leaves
the window (unselected). If the window is the focus window, then the text
cursor is highlighted no matter where the pointer is.
In VT102 mode, there
are escape sequences to activate and deactivate an alternate screen buffer,
which is the same size as the display area of the window. When activated,
the current screen is saved and replaced with the alternate screen. Saving
of lines scrolled off the top of the window is disabled until the normal
screen is restored. The termcap(5)
entry for xterm allows the visual editor
vi(1)
to switch to the alternate screen for editing and to restore the
screen on exit. A popup menu entry makes it simple to switch between the
normal and alternate screens for cut and paste.
In either VT102 or Tektronix
mode, there are escape sequences to change the name of the windows. Additionally,
in VT102 mode, xterm implements the window-manipulation control sequences
from dtterm, such as resizing the window, setting its location on the screen.
Xterm allows character-based applications to receive mouse events (currently
button-press and release events, and button-motion events) as keyboard control
sequences. See Xterm Control Sequences for details.
The xterm terminal
emulator accepts all of the standard X Toolkit command line options as
well as the following (if the option begins with a `+' instead of a `-', the
option is restored to its default value). The -version and -help options are
interpreted even if xterm cannot open the display, and are useful for testing
and configuration scripts:
- -version
- This causes xterm to print a version
number to the standard output.
- -help
- This causes xterm to print out a verbose
message describing its options. The message is written to the standard error.
The other options are used to control the appearance and behavior. Not all
options are necessarily configured into your copy of xterm.
- -132
- Normally,
the VT102 DECCOLM escape sequence that switches between 80 and 132 column
mode is ignored. This option causes the DECCOLM escape sequence to be recognized,
and the xterm window will resize appropriately.
- -ah
- This option indicates
that xterm should always highlight the text cursor. By default, xterm will
display a hollow text cursor whenever the focus is lost or the pointer
leaves the window.
- +ah
- This option indicates that xterm should do text cursor
highlighting based on focus.
- -ai
- This option disables active icon support
if that feature was compiled into xterm. This is equivalent to setting
the vt100 resource activeIcon to FALSE.
- +ai
- This option enables active icon
support if that feature was compiled into xterm. This is equivalent to
setting the vt100 resource activeIcon to TRUE.
- -aw
- This option indicates
that auto-wraparound should be allowed. This allows the cursor to automatically
wrap to the beginning of the next line when when it is at the rightmost
position of a line and text is output.
- +aw
- This option indicates that auto-wraparound
should not be allowed.
- -b number
- This option specifies the size of the inner
border (the distance between the outer edge of the characters and the window
border) in pixels. The default is 2.
- +bc
- turn off text cursor blinking. This
overrides the cursorBlink resource.
- -bc
- turn on text cursor blinking. This
overrides the cursorBlink resource.
- -bcf milliseconds
- time text cursor is
off when blinking
- -bcn milliseconds
- time text cursor is on when blinking
- -bdc
- Set the vt100 resource colorBDMode to FALSE, disabling the display
of characters with bold attribute as color
- +bdc
- Set the vt100 resource
colorBDMode to TRUE, enabling the display of characters with bold attribute
as color rather than bold
- -cb
- Set the vt100 resource cutToBeginningOfLine
to FALSE.
- +cb
- Set the vt100 resource cutToBeginningOfLine to TRUE.
- -cc characterclassrange:value[,...]
- This sets classes indicated by the given ranges for using in selecting
by words. See the section specifying character classes.
- -cm
- This option disables
recognition of ANSI color-change escape sequences.
- +cm
- This option enables
recognition of ANSI color-change escape sequences. This is the same as the
vt100 resource colorMode.
- -cn
- This option indicates that newlines should
not be cut in line-mode selections.
- +cn
- This option indicates that newlines
should be cut in line-mode selections.
- -cr color
- This option specifies the
color to use for text cursor. The default is to use the same foreground
color that is used for text.
- -cu
- This option indicates that xterm should
work around a bug in the more(1)
program that causes it to incorrectly
display lines that are exactly the width of the window and are followed
by a line beginning with a tab (the leading tabs are not displayed). This
option is so named because it was originally thought to be a bug in the
curses(3x)
cursor motion package.
- +cu
- This option indicates that xterm should
not work around the more(1)
bug mentioned above.
- -dc
- This option disables
the escape sequence to change dynamic colors: the vt100 foreground and
background colors, the text cursor color, the mouse cursor foreground and
background colors, the Tektronix emulator foreground and background colors,
and highlight color.
- +dc
- This option enables the escape sequence to change
dynamic colors.
- -e program [ arguments ... ]
- This option specifies the program
(and its command line arguments) to be run in the xterm window. It also
sets the window title and icon name to be the basename of the program being
executed if neither -T nor -n are given on the command line. This must be
the last option on the command line.
- -fb font
- This option specifies a font
to be used when displaying bold text. This font must be the same height
and width as the normal font. If only one of the normal or bold fonts is
specified, it will be used as the normal font and the bold font will be
produced by overstriking this font. The default is to do overstriking of
the normal font.
- -fi
- This option sets the font for active icons if that feature
was compiled into xterm.
- -hc color
- This option specifies the color to use
for the background of selected or otherwise highlighted text. If not specified,
reverse video is used.
- -hf
- This option indicates that HP Function Key escape
codes should be generated for function keys.
- +hf
- This option indicates that
HP Function Key escape codes should not be generated for function keys.
- -hold
- Turn on the hold resource, i.e., 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.
- +hold
- Turn off the hold resource, i.e.,
xterm will immediately destroy its window when the shell command completes.
- -ie
- Turn on the ptyInitialErase resource, i.e., use the pseudo-terminal's sense
of the stty erase value.
- +ie
- Turn off the ptyInitialErase resource, i.e.,
set the stty erase value using the kb string from the termcap entry as
a reference, if available.
- -im
- Turn on the useInsertMode resource.
- +im
- Turn
off the useInsertMode resource.
- -j
- This option indicates that xterm should
do jump scrolling. Normally, text is scrolled one line at a time; this
option allows xterm to move multiple lines at a time so that it doesn't
fall as far behind. Its use is strongly recommended since it make xterm
much faster when scanning through large amounts of text. The VT100 escape
sequences for enabling and disabling smooth scroll as well as the ``VT Options''
menu can be used to turn this feature on or off.
- +j
- This option indicates
that xterm should not do jump scrolling.
- -leftbar
- Force scrollbar to the
left side of VT100 screen. This is the default, unless you have set the
rightScrollBar resource.
- -ls
- This option indicates that the shell that is
started in the xterm window will be a login shell (i.e., the first character
of argv[0] will be a dash, indicating to the shell that it should read
the user's .login or .profile).
Note that this is incompatible with -e, since
the login program does not provide a way to specify the command to run
in the new shell. If you specify both, xterm uses -ls.
- +ls
- This option indicates
that the shell that is started should not be a login shell (i.e. it will
be a normal ``subshell'').
- -mb
- This option indicates that xterm should ring a
margin bell when the user types near the right end of a line. This option
can be turned on and off from the ``VT Options'' menu.
- +mb
- This option indicates
that margin bell should not be rung.
- -mc milliseconds
- This option specifies
the maximum time between multi-click selections.
- -mesg
- Turn off the messages
resource, i.e., disallow write access to the terminal.
- +mesg
- Turn on the messages
resource, i.e., allow write access to the terminal.
- -ms color
- This option specifies
the color to be used for the pointer cursor. The default is to use the
foreground color.
- -nb number
- This option specifies the number of characters
from the right end of a line at which the margin bell, if enabled, will
ring. The default is 10.
- -nul
- This option enables the display of underlining.
- +nul
- This option disables the display of underlining.
- -pc
- This option enables
the PC-style use of bold colors (see boldColors resource).
- +pc
- This option
disables the PC-style use of bold colors.
- -rightbar
- Force scrollbar to the
right side of VT100 screen.
- -rw
- This option indicates that reverse-wraparound
should be allowed. This allows the cursor to back up from the leftmost
column of one line to the rightmost column of the previous line. This is
very useful for editing long shell command lines and is encouraged. This
option can be turned on and off from the ``VT Options'' menu.
- +rw
- This option
indicates that reverse-wraparound should not be allowed.
- -s
- This option indicates
that xterm may scroll asynchronously, meaning that the screen does not
have to be kept completely up to date while scrolling. This allows xterm
to run faster when network latencies are very high and is typically useful
when running across a very large internet or many gateways.
- +s
- This option
indicates that xterm should scroll synchronously.
- -samename
- Doesn't send title
and icon name change requests when the request would have no effect: the
name isn't 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.
- +samename
- Always send title and icon name change requests.
- -sb
- This option indicates
that some number of lines that are scrolled off the top of the window should
be saved and that a scrollbar should be displayed so that those lines can
be viewed. This option may be turned on and off from the ``VT Options'' menu.
- +sb
- This option indicates that a scrollbar should not be displayed.
- -sf
- This
option indicates that Sun Function Key escape codes should be generated
for function keys.
- +sf
- This option indicates that the standard escape codes
should be generated for function keys.
- -si
- This option indicates that output
to a window should not automatically reposition the screen to the bottom
of the scrolling region. This option can be turned on and off from the ``VT
Options'' menu.
- +si
- This option indicates that output to a window should cause
it to scroll to the bottom.
- -sk
- This option indicates that pressing a key
while using the scrollbar to review previous lines of text should cause
the window to be repositioned automatically in the normal position at the
bottom of the scroll region.
- +sk
- This option indicates that pressing a key
while using the scrollbar should not cause the window to be repositioned.
- -sl number
- This option specifies the number of lines to save that have been
scrolled off the top of the screen. The default is 64.
- -sp
- This option indicates
that Sun/PC keyboard should be assumed, providing mapping for keypad `+'
to `,', and CTRL-F1 to F13, CTRL-F2 to F14, etc.
- +sp
- This option indicates that
the standard escape codes should be generated for keypad and function keys.
- -t
- This option indicates that xterm should start in Tektronix mode, rather
than in VT102 mode. Switching between the two windows is done using the
``Options'' menus.
- +t
- This option indicates that xterm should start in VT102
mode.
- -ti term_id
- Specify the name used by xterm to select the correct response
to terminal ID queries. It also specifies the emulation level, used to determine
the type of response to a DA control sequence. Valid values include vt52,
vt100, vt101, vt102, and vt220 (the "vt" is optional). The default is vt100.
The term_id argument specifies the terminal ID to use. (This is the same
as the decTerminalID resource).
- -tm string
- This option specifies a series
of terminal setting keywords followed by the characters that should be
bound to those functions, similar to the stty program. Allowable keywords
include: intr, quit, erase, kill, eof, eol, swtch, start, stop, brk, susp,
dsusp, rprnt, flush, weras, and lnext. Control characters may be specified
as ^char (e.g., ^c or ^u) and ^? may be used to indicate delete (127).
- -tn name
- 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.
- -u8
- This option sets the utf8 resource.
When utf8 is set, xterm interprets incoming data as UTF-8. This sets wideChars
as a side-effect.
- +u8
- This option resets the utf8 resource.
- -ulc
- This option
disables the display of characters with underline attribute as color rather
than with underlining.
- +ulc
- This option enables the display of characters
with underline attribute as color rather than with underlining.
- -ut
- This
option indicates that xterm shouldn't write a record into the the system
utmp log file.
- +ut
- This option indicates that xterm should write a record
into the system utmp log file.
- -vb
- This option indicates that a visual bell
is preferred over an audible one. Instead of ringing the terminal bell whenever
a Control-G is received, the window will be flashed.
- +vb
- This option indicates
that a visual bell should not be used.
- -wc
- This option sets the wideChars
resource. When wideChars is set, xterm maintains internal structures for
16-bit characters.
- +wc
- This option resets the wideChars resource.
- -wf
- This
option indicates that xterm should wait for the window to be mapped the
first time before starting the subprocess so that the initial terminal
size settings and environment variables are correct. It is the application's
responsibility to catch subsequent terminal size changes.
- +wf
- This option
indicates that xterm show not wait before starting the subprocess.
- -ziconbeep
percent
- Same as zIconBeep resource. If percent 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.)
- -C
- This option indicates that this window should
receive console output. This is not supported on all systems. To obtain
console output, you must be the owner of the console device, and you must
have read and write permission for it. If you are running X under xdm on
the console screen you may need to have the session startup and reset programs
explicitly change the ownership of the console device in order to get this
option to work.
- -Sccn
- This option specifies the last two letters of the name
of a pseudo-terminal to use in slave mode, plus the number of the inherited
file descriptor. The option is parsed ``%c%c%d''. This allows xterm to be used
as an input and output channel for an existing program and is sometimes
used in specialized applications.
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(1)
.
- -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(1)
.
- -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.
- -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 as well as:
- 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''.
- 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 doesn't send title and icon name change requests
when the request would have no effect: the name isn't 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''.
- 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 to F13, CTRL-F2 to F14, etc., 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 following resources are specified as part of the vt100 widget (class
VT100):
- 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.''
- 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.
- 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, a hollow text cursor is displayed whenever the pointer
moves out of the window or the window loses the input focus.
- 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.
- 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.

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.

will return misleading font metrics. The default is ``true''. If disabled, xterm
will simulate doublesize characters by drawing normal characters with spaces
between them.
- 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.''

- Specifies the preferred size and position of the VT102 window.
- 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.''
- 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.

- 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.
- loginShell (class LoginShell)
- Specifies whether
or not the shell to be run in the window should be started as a login shell.

- 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.''
- 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
Foreground)
- Specifies the foreground color of the pointer. The default
is ``XtDefaultForeground.''
- pointerColorBackground (class Background)
- 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.''
- 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.''
- 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.''

(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.''
- 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.
- 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 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.
- translations (class Translations)
- Specifies the key and
button bindings for menus, selections, ``programmed strings,'' etc. See ACTIONS
below.
- 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.
- 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.
- 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.''
- wideChars
(class WideChars)
- Specifies if xterm should respond to control sequences
that process 16-bit characters.

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 255, corresponding
to the 8-bit 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.
The default table is
static int charClass[256] = {

For example, the string ``33:48,37:48,45-47:48,64:48'' 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)

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'' and ``TERMCAP''
properly for the size 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.
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.
- /usr/lib/X11/app-defaults/XTerm
- the xterm default application resources.
- /usr/lib/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.

Xterm Control Sequences (this is the file ctlseqs.ms).

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 don't
know about each other. Ideally, you'd like to be able to pick and choose
emulator widgets and stick them into a single control widget.
There needs
to be a dialog box to allow entry of the Tek COPY file name.
