NAME
       cdialog - display dialog	boxes from shell scripts

SYNOPSIS
       cdialog --clear
       cdialog --create-rc file
       cdialog --print-maxsize
       cdialog common-options box-options

DESCRIPTION
       Cdialog	is  a program that will	let you	present	a variety of questions
       or display messages using dialog	boxes  from  a	shell  script.	 These
       types  of  dialog boxes are implemented (though not all are necessarily
       compiled	into cdialog):

	      buildlist, calendar, checklist, dselect, editbox,	form, fselect,
	      gauge, infobox, inputbox,	inputmenu, menu, mixedform,
	      mixedgauge, msgbox (message), passwordbox, passwordform, pause,
	      prgbox, programbox, progressbox, radiolist, rangebox, tailbox,
	      tailboxbg, textbox, timebox, treeview, and yesno (yes/no).

       You can put more	than one dialog	box into a script:

       o   Use the "--and-widget" token	to force cdialog  to  proceed  to  the
	   next	dialog unless you have pressed ESC to cancel, or

       o   Simply  add	the  tokens  for  the next dialog box, making a	chain.
	   Cdialog stops chaining when the return code from a dialog  is  non-
	   zero, e.g., Cancel or No (see DIAGNOSTICS).

       Some  widgets,  e.g.,  checklist,  will write text to cdialog's output.
       Normally	that is	the standard error, but	there are options for changing
       this:  "--output-fd", "--stderr"	and "--stdout".	 No text is written if
       the Cancel button (or ESC) is pressed;  cdialog	exits  immediately  in
       that case.

OPTIONS
       All  options  begin  with  "--"	(two ASCII hyphens, for	the benefit of
       those using systems with	deranged locale	support).

       A "--" by itself	is used	as an escape, i.e., the	next token on the com-
       mand-line is not	treated	as an option.
	      cdialog --title -- --Not an option

       The  "--args"  option tells cdialog to list the command-line parameters
       to the standard error.  This is useful when debugging  complex  scripts
       using the "--" and "--file", since the command-line may be rewritten as
       these are expanded.

       The "--file" option tells cdialog to  read  parameters  from  the  file
       named as	its value.
	      cdialog --file parameterfile
       Blanks not within double-quotes are discarded (use backslashes to quote
       single characters).  The	result is inserted into	the command-line,  re-
       placing	"--file" and its option	value.	Interpretation of the command-
       line resumes from that point.  If parameterfile begins with "&",	 cdia-
       log  interprets	the  following text as a file descriptor number	rather
       than a filename.

   Common Options
       Most of the common options are reset before processing each widget.

       --ascii-lines
	      Rather than draw graphics	lines around boxes, draw ASCII "+" and
	      "-" in the same place.  See also "--no-lines".

       --aspect	ratio
	      This  gives  you some control over the box dimensions when using
	      auto sizing (specifying 0	for height and width).	It  represents
	      width / height.  The default is 9, which means 9 characters wide
	      to every 1 line high.

       --backtitle backtitle
	      Specifies	a backtitle string to be displayed on the backdrop, at
	      the top of the screen.

       --begin y x
	      Specify the position of the upper	left corner of a dialog	box on
	      the screen.

       --cancel-label string
	      Override the label used for "Cancel" buttons.

       --clear
	      Clears the widget	screen,	keeping	only  the  screen_color	 back-
	      ground.	Use  this when you combine widgets with	"--and-widget"
	      to erase the contents of a previous widget on the	screen,	so  it
	      won't  be	seen under the contents	of a following widget.	Under-
	      stand this as the	complement of "--keep-window".	To compare the
	      effects, use these:

	      All three	widgets	visible, staircase effect, ordered 1,2,3:

	      cdialog \
					     --begin 2 2 --yesno "" 0 0	\
		  --and-widget		     --begin 4 4 --yesno "" 0 0	\
		  --and-widget		     --begin 6 6 --yesno "" 0 0

	      Only the last widget is left visible:

	      cdialog \
			       --clear	     --begin 2 2 --yesno "" 0 0	\
		  --and-widget --clear	     --begin 4 4 --yesno "" 0 0	\
		  --and-widget		     --begin 6 6 --yesno "" 0 0

	      All three	widgets	visible, staircase effect, ordered 3,2,1:

	      cdialog \
			       --keep-window --begin 2 2 --yesno "" 0 0	\
		  --and-widget --keep-window --begin 4 4 --yesno "" 0 0	\
		  --and-widget		     --begin 6 6 --yesno "" 0 0

	      First and	third widget visible, staircase	effect,	ordered	3,1:

	      cdialog \
			       --keep-window --begin 2 2 --yesno "" 0 0	\
		  --and-widget --clear	     --begin 4 4 --yesno "" 0 0	\
		  --and-widget		     --begin 6 6 --yesno "" 0 0

	      Note,  if	 you  want to restore original console colors and send
	      your cursor home after the dialog	program	has  exited,  use  the
	      clear (1)	command.

       --colors
	      Interpret	embedded "\Z" sequences	in the dialog text by the fol-
	      lowing character,	which tells cdialog to set colors or video at-
	      tributes:

	      o	  0  through  7	 are  the  ANSI	 color numbers used in curses:
		  black, red, green, yellow, blue, magenta, cyan and white re-
		  spectively.

	      o	  Bold is set by 'b', reset by 'B'.

	      o	  Reverse is set by 'r', reset by 'R'.

	      o	  Underline is set by 'u', reset by 'U'.

	      o	  The  settings	 are cumulative, e.g., "\Zb\Z1"	makes the fol-
		  lowing text bold (perhaps bright) red.

	      o	  Restore normal settings with "\Zn".

       --column-separator string
	      Tell cdialog to split data for radio/checkboxes and menus	on the
	      occurrences of the given string, and to align the	split data in-
	      to columns.

       --cr-wrap
	      Interpret	embedded newlines in the dialog	text as	a  newline  on
	      the screen.  Otherwise, cdialog will only	wrap lines where need-
	      ed to fit	inside the text	box.

	      Even though you can control line breaks with this, Cdialog  will
	      still wrap any lines that	are too	long for the width of the box.
	      Without cr-wrap, the layout of your text	may  be	 formatted  to
	      look  nice  in  the source code of your script without affecting
	      the way it will look in the dialog.

	      See also the "--no-collapse" and "--trim"	options.

       --create-rc file
	      When cdialog supports run-time configuration, this can  be  used
	      to  dump	a  sample  configuration file to the file specified by
	      file.

       --date-format format
	      If the host provides strftime, this option allows	you to specify
	      the  format  of the date printed for the --calendar widget.  The
	      time of day (hour, minute, second) are the current local time.

       --defaultno
	      Make the default value of	the yes/no box a No.   Likewise,  make
	      the  default  button of widgets that provide "OK"	and "Cancel" a
	      Cancel.  If "--nocancel" or "--visit-items" are given those  op-
	      tions  overrides	this,  making  the default button always "Yes"
	      (internally the same as "OK").

       --default-button	string
	      Set the default (preselected) button in a	widget.	 By preselect-
	      ing  a button, a script makes it possible	for the	user to	simply
	      press Enter to proceed through a dialog  with  minimum  interac-
	      tion.

	      The  option's  value is the name of the button: ok, yes, cancel,
	      no, help or extra.

	      Normally the first button	in each	widget is  the	default.   The
	      first button shown is determined by the widget together with the
	      "--nook" and "--nocancel options.	 If this option	is not	given,
	      there is no default button assigned.

       --default-item string
	      Set the default item in a	checklist, form	or menu	box.  Normally
	      the first	item in	the box	is the default.

       --exit-label string
	      Override the label used for "EXIT" buttons.

       --extra-button
	      Show an extra button, between "OK" and "Cancel" buttons.

       --extra-label string
	      Override the label used for "Extra" buttons.  Note:  for	input-
	      menu widgets, this defaults to "Rename".

       --help Prints  the  help	message	to the standard	output and exits.  The
	      help message is also printed if no options are given, or	if  an
	      unrecognized option is given.

       --help-button
	      Show  a  help-button  after  "OK"	and "Cancel" buttons, i.e., in
	      checklist, radiolist and menu boxes.

	      On exit, the return status will indicate that  the  Help	button
	      was  pressed.   Cdialog  will also write a message to its	output
	      after the	token "HELP":

	      o	  If "--item-help" is also given, the item-help	text  will  be
		  written.

	      o	  Otherwise, the item's	tag (the first field) will be written.

	      You   can	 use  the  --help-tags	option	and/or	set  the  DIA-
	      LOG_ITEM_HELP environment	variable to modify these messages  and
	      exit-status.

       --help-label string
	      Override the label used for "Help" buttons.

       --help-status
	      If  the help-button is selected, writes the checklist, radiolist
	      or form information  after  the  item-help  "HELP"  information.
	      This  can	 be used to reconstruct	the state of a checklist after
	      processing the help request.

       --help-tags
	      Modify the messages written on exit for --help-button by	making
	      them  always just	the item's tag.	 This does not affect the exit
	      status code.

       --hfile filename
	      Display the given	file using a textbox when the user presses F1.

       --hline string
	      Display the given	string centered	at the bottom of the widget.

       --ignore
	      Ignore options that cdialog does not recognize.  Some well-known
	      ones  such  as "--icon" are ignored anyway, but this is a	better
	      choice for compatibility with other implementations.

       --input-fd fd
	      Read keyboard input from the given file descriptor.  Most	 cdia-
	      log  scripts  read from the standard input, but the gauge	widget
	      reads a pipe (which is always standard input).  Some  configura-
	      tions do not work	properly when cdialog tries to reopen the ter-
	      minal.  Use this option (with appropriate	juggling  of  file-de-
	      scriptors) if your script	must work in that type of environment.

       --insecure
	      Makes the	password widget	friendlier but less secure, by echoing
	      asterisks	for each character.

       --iso-week
	      Set the starting point for the week-number shown in the  "--cal-
	      endar" option according to ISO-8601, which starts	numbering with
	      the first	week which includes a Thursday in January.

       --item-help
	      Interpret	the tags data for checklist, radiolist and menu	 boxes
	      adding  a	 column	 which	is displayed in	the bottom line	of the
	      screen, for the currently	selected item.

       --keep-tite
	      When built with ncurses, cdialog normally	checks to see if it is
	      running in an xterm, and in that case tries to suppress the ini-
	      tialization strings that would make it switch to	the  alternate
	      screen.	Switching  between the normal and alternate screens is
	      visually distracting in a	 script	 which	runs  cdialog  several
	      times.   Use  this option	to allow cdialog to use	those initial-
	      ization strings.

       --keep-window
	      Normally when cdialog performs several  tailboxbg	 widgets  con-
	      nected  by  "--and-widget",  it  clears  the old widget from the
	      screen by	painting over it.  Use this option  to	suppress  that
	      repainting.

	      At  exit,	 cdialog  repaints  all	of the widgets which have been
	      marked with "--keep-window", even	if they	are not	tailboxbg wid-
	      gets.   That  causes them	to be repainted	in reverse order.  See
	      the discussion of	the "--clear" option for examples.

       --last-key
	      At exit, report the last key which the user  entered.   This  is
	      the  curses  key code rather than	a symbol or literal character.
	      It can be	used by	scripts	to distinguish between two keys	 which
	      are bound	to the same action.

       --max-input size
	      Limit  input  strings  to	the given size.	 If not	specified, the
	      limit is 2048.

       --no-cancel

       --nocancel
	      Suppress the "Cancel" button in checklist, inputbox and menu box
	      modes.   A script	can still test if the user pressed the ESC key
	      to cancel	to quit.

       --no-collapse
	      Normally cdialog converts	tabs to	spaces	and  reduces  multiple
	      spaces  to  a single space for text which	is displayed in	a mes-
	      sage boxes, etc.	Use this option	to disable that	feature.  Note
	      that  cdialog  will  still wrap text, subject to the "--cr-wrap"
	      and "--trim" options.

       --no-items
	      Some widgets (checklist, inputmenu, radiolist, menu)  display  a
	      list with	two columns (a "tag" and "item", i.e., "description").
	      This option tells	cdialog	to read	 shorter  rows,	 omitting  the
	      "item"  part of the list.	 This is occasionally useful, e.g., if
	      the tags provide enough information.

	      See also --no-tags.  If both options are given, this one is  ig-
	      nored.

       --no-kill
	      Tells cdialog to put the tailboxbg box in	the background,	print-
	      ing its process id to cdialog's output.  SIGHUP is disabled  for
	      the background process.

       --no-label string
	      Override the label used for "No" buttons.

       --no-lines
	      Rather  than  draw  lines	 around	boxes, draw spaces in the same
	      place.  See also "--ascii-lines".

       --no-mouse
	      Do not enable the	mouse.

       --no-nl-expand
	      Do not convert "\n" substrings of	the message/prompt  text  into
	      literal newlines.

       --no-ok

       --nook Suppress	the  "OK"  button  in checklist, inputbox and menu box
	      modes.  A	script can still test if the user pressed the  "Enter"
	      key to accept the	data.

       --no-shadow
	      Suppress	shadows	that would be drawn to the right and bottom of
	      each dialog box.

       --no-tags
	      Some widgets (checklist, inputmenu, radiolist, menu)  display  a
	      list  with  two columns (a "tag" and "description").  The	tag is
	      useful for scripting, but	may not	help the user.	The  --no-tags
	      option (from Xdialog) may	be used	to suppress the	column of tags
	      from the display.	 Unlike	the --no-items option, this  does  not
	      affect the data which is read from the script.

	      Xdialog  does  not  display  the	tag  column  for the analogous
	      buildlist	and treeview widgets; cdialog does the same.

	      Normally cdialog allows you to quickly move to  entries  on  the
	      displayed	 list,	by  matching  a	 single	character to the first
	      character	of the tag.  When the --no-tags	option is given, cdia-
	      log  matches against the first character of the description.  In
	      either case, the matchable character is highlighted.

       --ok-label string
	      Override the label used for "OK" buttons.

       --output-fd fd
	      Direct output  to	 the  given  file  descriptor.	 Most  cdialog
	      scripts write to the standard error, but error messages may also
	      be written there,	depending on your script.

       --separator string

       --output-separatorstring
	      Specify a	string that will separate the output on	cdialog's out-
	      put  from	checklists, rather than	a newline (for --separate-out-
	      put) or a	space.	This applies to	other widgets  such  as	 forms
	      and editboxes which normally use a newline.

       --print-maxsize
	      Print  the  maximum size of dialog boxes,	i.e., the screen size,
	      to cdialog's output.  This may be	used alone, without other  op-
	      tions.

       --print-size
	      Prints the size of each dialog box to cdialog's output.

       --print-version
	      Prints  cdialog's	version	to cdialog's output.  This may be used
	      alone, without other options.  It	does not cause dialog to  exit
	      by itself.

       --quoted
	      Normally	cdialog	 quotes	the strings returned by	checklist's as
	      well as the item-help text.  Use this option to quote all	string
	      results.

       --scrollbar
	      For  widgets  holding a scrollable set of	data, draw a scrollbar
	      on its right-margin.  This does not respond to the mouse.

       --separate-output
	      For certain widgets (buildlist, checklist, treeview), output re-
	      sult  one	 line  at  a  time, with no quoting.  This facilitates
	      parsing by another program.

       --separate-widget string
	      Specify a	string that will separate the output on	cdialog's out-
	      put  from	each widget.  This is used to simplify parsing the re-
	      sult of a	dialog with several widgets.  If this  option  is  not
	      given, the default separator string is a tab character.

       --shadow
	      Draw a shadow to the right and bottom of each dialog box.

       --single-quoted
	      Use single-quoting as needed (and	no quotes if unneeded) for the
	      output of	checklist's as well as the item-help  text.   If  this
	      option  is not set, cdialog uses double quotes around each item.
	      In either	case, cdialog adds backslashes to make the output use-
	      ful in shell scripts.

       --size-err
	      Check  the  resulting  size of a dialog box before trying	to use
	      it, printing the resulting size if it is larger than the screen.
	      (This  option  is	 obsolete,  since  all	new-window  calls  are
	      checked).

       --sleep secs
	      Sleep (delay) for	the given number of seconds after processing a
	      dialog box.

       --stderr
	      Direct output to the standard error.  This is the	default, since
	      curses normally writes screen updates to the standard output.

       --stdout
	      Direct output to the standard output.  This option  is  provided
	      for  compatibility  with	Xdialog,  however using	it in portable
	      scripts is not recommended, since	 curses	 normally  writes  its
	      screen  updates to the standard output.  If you use this option,
	      cdialog attempts to reopen the terminal so it can	write  to  the
	      display.	 Depending  on the platform and	your environment, that
	      may fail.

       --tab-correct
	      Convert each tab character  to  one  or  more  spaces  (for  the
	      textbox  widget;	otherwise to a single space).  Otherwise, tabs
	      are rendered according to	the curses  library's  interpretation.
	      The --no-collapse	option disables	tab expansion.

       --tab-len n
	      Specify  the  number  of spaces that a tab character occupies if
	      the "--tab-correct" option is given.  The	default	 is  8.	  This
	      option is	only effective for the textbox widget.

       --time-format format
	      If the host provides strftime, this option allows	you to specify
	      the format of the	time printed for the  --timebox	 widget.   The
	      day,  month,  year values	in this	case are for the current local
	      time.

       --timeout secs
	      Timeout (exit with error code) if	no user	 response  within  the
	      given number of seconds.	A timeout of zero seconds is ignored.

	      This  option  is	ignored	 by  the "--pause" widget.  It is also
	      overridden if the	background "--tailboxbg"  option  is  used  to
	      setup multiple concurrent	widgets.

       --title title
	      Specifies	 a title string	to be displayed	at the top of the dia-
	      log box.

       --trace filename
	      logs the command-line parameters,	keystrokes and other  informa-
	      tion to the given	file.  If dialog reads a configure file, it is
	      logged as	well.  Piped input to the gauge	widget is logged.  Use
	      control/T	to log a picture of the	current	dialog window.

       --week-start day
	      sets the starting	day for	the week, used in the "--calendar" op-
	      tion.  The day parameter can be

	      o	  a number (0 to 6, Sunday through Saturday using POSIX) or

	      o	  the special value "locale" (this works  with	systems	 using
		  glibc,  providing  an	 extension  to the locale command, the
		  first_weekday	value).

	      o	  a string matching one	of the abbreviations for  the  day  of
		  the  week shown in the calendar widget, e.g.,	"Mo" for "Mon-
		  day".

       The cdialog program handles some	command-line parameters	specially, and
       removes	them from the parameter	list as	they are processed.  For exam-
       ple, if the first option	is --trace, then that is  processed  (and  re-
       moved) before cdialog initializes the display.

       --trim eliminate	 leading  blanks,  trim	 literal newlines and repeated
	      blanks from message text.

	      See also the "--cr-wrap" and "--no-collapse" options.

       --version
	      Prints cdialog's version to the standard output, and exits.  See
	      also "--print-version".

       --visit-items
	      Modify  the  tab-traversal  of checklist,	radiolist, menubox and
	      inputmenu	to include the list of items as	 one  of  the  states.
	      This  is useful as a visual aid, i.e., the cursor	position helps
	      some users.

	      When this	option is given, the cursor is initially placed	on the
	      list.   Abbreviations (the first letter of the tag) apply	to the
	      list items.  If you tab to the button row,  abbreviations	 apply
	      to the buttons.

       --yes-label string
	      Override the label used for "Yes"	buttons.

   Box Options
       All dialog boxes	have at	least three parameters:

       text   the caption or contents of the box.

       height the height of the	dialog box.

       width  the width	of the dialog box.

       Other parameters	depend on the box type.

       --buildlist text	height width list-height [ tag item status ] ...
	      A	 buildlist  dialog displays two	lists, side-by-side.  The list
	      on the left shows	unselected items.  The list on the right shows
	      selected	items.	As items are selected or unselected, they move
	      between the lists.

	      Use a carriage return or the "OK"	button to accept  the  current
	      value  in	the selected-window and	exit.  The results are written
	      using the	order displayed	in the selected-window.

	      The initial on/off state of each entry is	specified by status.

	      The dialog behaves like a	menu, using the	--visit-items to  con-
	      trol whether the cursor is allowed to visit the lists directly.

	      o	  If --visit-items is not given, tab-traversal uses two	states
		  (OK/Cancel).

	      o	  If --visit-items is given, tab-traversal  uses  four	states
		  (Left/Right/OK/Cancel).

	      Whether  or  not	--visit-items is given,	it is possible to move
	      the highlight between the	two lists using	the default "^"	(left-
	      column) and "$" (right-column) keys.

	      On  exit,	 a  list  of the tag strings of	those entries that are
	      turned on	will be	printed	on cdialog's output.

	      If the "--separate-output" option	is not given, the strings will
	      be  quoted  as  needed to	make it	simple for scripts to separate
	      them.  By	default, this uses double-quotes.  See the  "--single-
	      quoted" option, which modifies the quoting behavior.

       --calendar text height width day	month year
	      A	 calendar  box	displays month,	day and	year in	separately ad-
	      justable windows.	 If the	values for  day,  month	 or  year  are
	      missing or negative, the current date's corresponding values are
	      used.  You can increment or decrement any	 of  those  using  the
	      left-, up-, right-, and down-arrows.  Use	vi-style h, j, k and l
	      for moving around	the array of days in  a	 month.	  Use  tab  or
	      backtab  to move between windows.	 If the	year is	given as zero,
	      the current date is used as an initial value.

	      On exit, the date	is printed in the  form	 day/month/year.   The
	      format can be overridden using the --date-format option.

       --checklist text	height width list-height [ tag item status ] ...
	      A	checklist box is similar to a menu box;	there are multiple en-
	      tries presented in the form of a menu.   Another	difference  is
	      that you can indicate which entry	is currently selected, by set-
	      ting its status to on.  Instead of choosing one entry among  the
	      entries,	each  entry  can be turned on or off by	the user.  The
	      initial on/off state of each entry is specified by status.

	      On exit, a list of the tag strings of  those  entries  that  are
	      turned on	will be	printed	on cdialog's output.

	      If the "--separate-output" option	is not given, the strings will
	      be quoted	as needed to make it simple for	 scripts  to  separate
	      them.   By default, this uses double-quotes.  See	the "--single-
	      quoted" option, which modifies the quoting behavior.

       --dselect filepath height width
	      The directory-selection dialog displays a	text-entry  window  in
	      which  you  can  type a directory, and above that	a windows with
	      directory	names.

	      Here filepath can	be a filepath in which case the	directory win-
	      dow  will	 display  the  contents	of the path and	the text-entry
	      window will contain the preselected directory.

	      Use tab or arrow keys to move between the	windows.   Within  the
	      directory	 window, use the up/down arrow keys to scroll the cur-
	      rent selection.  Use the space-bar to copy the current selection
	      into the text-entry window.

	      Typing any printable characters switches focus to	the text-entry
	      window, entering that character as well as scrolling the	direc-
	      tory window to the closest match.

	      Use  a  carriage return or the "OK" button to accept the current
	      value in the text-entry window and exit.

	      On exit, the contents of the text-entry window  are  written  to
	      cdialog's	output.

       --editbox filepath height width
	      The  edit-box  dialog displays a copy of the file.  You may edit
	      it using the backspace, delete and cursor	keys to	correct	typing
	      errors.	It  also recognizes pageup/pagedown.  Unlike the --in-
	      putbox, you must tab to the "OK" or "Cancel"  buttons  to	 close
	      the  dialog.  Pressing the "Enter" key within the	box will split
	      the corresponding	line.

	      On exit, the contents of the edit	window are  written  to	 cdia-
	      log's output.

       --form text height width	formheight [ label y x item y x	flen ilen ] ...
	      The form dialog displays a form consisting of labels and fields,
	      which are	positioned on a	scrollable window by coordinates given
	      in the script.  The field	length flen and	input-length ilen tell
	      how long the field can be.  The former defines the length	 shown
	      for  a  selected field, while the	latter defines the permissible
	      length of	the data entered in the	field.

	      o	  If flen is zero, the corresponding field cannot be  altered.
		  and  the  contents  of  the  field  determine	the displayed-
		  length.

	      o	  If flen is negative, the corresponding field cannot  be  al-
		  tered,  and  the  negated  value of flen is used as the dis-
		  played-length.

	      o	  If ilen is zero, it is set to	flen.

	      Use up/down arrows (or control/N,	 control/P)  to	 move  between
	      fields.  Use tab to move between windows.

	      On  exit,	 the  contents of the form-fields are written to cdia-
	      log's output, each field separated by a newline.	The text  used
	      to  fill	non-editable  fields (flen is zero or negative)	is not
	      written out.

       --fselect filepath height width
	      The fselect (file-selection) dialog displays a text-entry	window
	      in  which	you can	type a filename	(or directory),	and above that
	      two windows with directory names and filenames.

	      Here filepath can	be a filepath in which case the	file  and  di-
	      rectory  windows	will  display the contents of the path and the
	      text-entry window	will contain the preselected filename.

	      Use tab or arrow keys to move between the	windows.   Within  the
	      directory	 or  filename  windows,	 use the up/down arrow keys to
	      scroll the current selection.  Use the  space-bar	 to  copy  the
	      current selection	into the text-entry window.

	      Typing any printable characters switches focus to	the text-entry
	      window, entering that character as well as scrolling the	direc-
	      tory and filename	windows	to the closest match.

	      Typing  the  space character forces cdialog to complete the cur-
	      rent name	(up to the point where there may be  a	match  against
	      more than	one entry).

	      Use  a  carriage return or the "OK" button to accept the current
	      value in the text-entry window and exit.

	      On exit, the contents of the text-entry window  are  written  to
	      cdialog's	output.

       --gauge text height width [percent]
	      A	 gauge	box displays a meter along the bottom of the box.  The
	      meter indicates the percentage.  New percentages are  read  from
	      standard	input,	one integer per	line.  The meter is updated to
	      reflect each new percentage.  If the standard  input  reads  the
	      string "XXX", then the first line	following is taken as an inte-
	      ger percentage, then subsequent lines up to  another  "XXX"  are
	      used  for	 a new prompt.	The gauge exits	when EOF is reached on
	      the standard input.

	      The percent value	denotes	the initial percentage	shown  in  the
	      meter.  If not specified,	it is zero.

	      On exit, no text is written to cdialog's output.	The widget ac-
	      cepts no input, so the exit status is always OK.

       --infobox text height width
	      An info box is basically a message box.  However,	in this	 case,
	      cdialog  will  exit  immediately after displaying	the message to
	      the user.	 The screen is not cleared when	cdialog	exits, so that
	      the  message  will  remain on the	screen until the calling shell
	      script clears it later.  This is useful when you want to	inform
	      the  user	 that some operations are carrying on that may require
	      some time	to finish.

	      On exit, no text is written to cdialog's	output.	  An  OK  exit
	      status is	returned.

       --inputbox text height width [init]
	      An  input	 box is	useful when you	want to	ask questions that re-
	      quire the	user to	input a	string as the answer.  If init is sup-
	      plied  it	is used	to initialize the input	string.	 When entering
	      the string, the backspace, delete	and cursor keys	can be used to
	      correct  typing  errors.	If the input string is longer than can
	      fit in the dialog	box, the input field will be scrolled.

	      On exit, the input string	will be	printed	on cdialog's output.

       --inputmenu text	height width menu-height [ tag item ] ...
	      An inputmenu box is very similar to an ordinary menu box.	 There
	      are only a few differences between them:

	      1.  The  entries are not automatically centered but left adjust-
		  ed.

	      2.  An extra button (called Rename) is  implied  to  rename  the
		  current item when it is pressed.

	      3.  It  is  possible to rename the current entry by pressing the
		  Rename button.  Then cdialog will  write  the	 following  on
		  cdialog's output.

		  RENAMED <tag>	<item>

       --menu text height width	menu-height [ tag item ] ...
	      As  its  name  suggests,	a menu box is a	dialog box that	can be
	      used to present a	list of	choices	in the form of a menu for  the
	      user to choose.  Choices are displayed in	the order given.  Each
	      menu entry consists of a tag string and an item string.  The tag
	      gives  the entry a name to distinguish it	from the other entries
	      in the menu.  The	item is	a short	description of the option that
	      the  entry  represents.	The user can move between the menu en-
	      tries by pressing	the cursor keys, the first letter of  the  tag
	      as  a  hot-key, or the number keys 1 through 9.  There are menu-
	      height entries displayed in the menu at one time,	but  the  menu
	      will be scrolled if there	are more entries than that.

	      On exit the tag of the chosen menu entry will be printed on cdi-
	      alog's output.  If the "--help-button" option is given, the cor-
	      responding  help	text  will  be printed if the user selects the
	      help button.

       --mixedform text	height width formheight	[ label	y x item y x flen ilen itype ] ...
	      The mixedform dialog displays a form consisting  of  labels  and
	      fields,  much  like  the	--form dialog.	It differs by adding a
	      field-type parameter to each field's description.	 Each  bit  in
	      the type denotes an attribute of the field:

	      1	   hidden, e.g., a password field.

	      2	   readonly, e.g., a label.

       --mixedgauge text height	width percent [	tag1 item1 ] ...
	      A	 mixedgauge  box displays a meter along	the bottom of the box.
	      The meter	indicates the percentage.

	      It also displays a list of the tag- and item-values at  the  top
	      of the box.  See cdialog(3) for the tag values.

	      The  text	is shown as a caption between the list and meter.  The
	      percent value denotes the	initial	percentage shown in the	meter.

	      No provision is made for reading data from the standard input as
	      --gauge does.

	      On exit, no text is written to cdialog's output.	The widget ac-
	      cepts no input, so the exit status is always OK.

       --msgbox	text height width
	      A	message	box is very similar to a yes/no	box.  The only differ-
	      ence  between  a	message	box and	a yes/no box is	that a message
	      box has only a single OK button.	You can	use this dialog	box to
	      display  any  message  you like.	After reading the message, the
	      user can press the ENTER key so that cdialog will	exit  and  the
	      calling shell script can continue	its operation.

	      If the message is	too large for the space, cdialog may allow you
	      to scroll	it, provided that the underlying curses	implementation
	      is  capable  enough.  In this case, a percentage is shown	in the
	      base of the widget.

	      On exit, no text is written to cdialog's output.	Only  an  "OK"
	      button  is provided for input, but an ESC	exit status may	be re-
	      turned.

       --pause text height width seconds
	      A	pause box displays a meter along the bottom of the  box.   The
	      meter  indicates	how  many  seconds remain until	the end	of the
	      pause.  The pause	exits when timeout  is	reached	 or  the  user
	      presses the OK button (status OK)	or the user presses the	CANCEL
	      button or	Esc key.

       --passwordbox text height width [init]
	      A	password box is	similar	to an input box, except	that the  text
	      the user enters is not displayed.	 This is useful	when prompting
	      for passwords or other sensitive information.  Be	aware that  if
	      anything is passed in "init", it will be visible in the system's
	      process table to casual snoopers.	 Also, it is very confusing to
	      the  user	 to  provide  them with	a default password they	cannot
	      see.  For	these reasons, using  "init"  is  highly  discouraged.
	      See "--insecure" if you do not care about	your password.

	      On exit, the input string	will be	printed	on cdialog's output.

       --passwordform text height width	formheight [ label y x item y x	flen ilen ] ...
	      This  is	identical  to  --form  except that all text fields are
	      treated as password widgets rather than inputbox widgets.

       --prgbox	text command height width

       --prgbox	command	height width
	      A	prgbox is very similar to a programbox.

	      This dialog box is used to display the output of a command  that
	      is specified as an argument to prgbox.

	      After the	command	completes, the user can	press the ENTER	key so
	      that dialog will exit and	the calling shell script can  continue
	      its operation.

	      If  three	 parameters  are given,	it displays the	text under the
	      title, delineated	from the scrolling file's contents.   If  only
	      two parameters are given,	this text is omitted.

       --programbox text height	width

       --programbox height width
	      A	programbox is very similar to a	progressbox.  The only differ-
	      ence between a program box and a progress	box is that a  program
	      box  displays  an	 OK  button  (but  only	after the command com-
	      pletes).

	      This dialog box is used to display the piped output  of  a  com-
	      mand.  After the command completes, the user can press the ENTER
	      key so that dialog will exit and the calling  shell  script  can
	      continue its operation.

	      If  three	 parameters  are given,	it displays the	text under the
	      title, delineated	from the scrolling file's contents.   If  only
	      two parameters are given,	this text is omitted.

       --progressbox text height width

       --progressbox height width
	      A	progressbox is similar to an tailbox, except that

	      a) rather	than displaying	the contents of	a file,
		 it displays the piped output of a command and

	      b) it will exit when it reaches the end of the file
		 (there	is no "OK" button).

	      If  three	 parameters  are given,	it displays the	text under the
	      title, delineated	from the scrolling file's contents.   If  only
	      two parameters are given,	this text is omitted.

       --radiolist text	height width list-height  [ tag	item status ] ...
	      A	 radiolist  box	is similar to a	menu box.  The only difference
	      is that you can indicate which entry is currently	 selected,  by
	      setting its status to on.

	      On  exit,	 the  tag of the selected item is written to cdialog's
	      output.

       --tailbox file height width
	      Display text from	a file in a dialog box,	as in a	"tail -f" com-
	      mand.   Scroll  left/right using vi-style	'h' and	'l', or	arrow-
	      keys.  A '0' resets the scrolling.

	      On exit, no text is written to cdialog's output.	Only  an  "OK"
	      button  is provided for input, but an ESC	exit status may	be re-
	      turned.

       --rangebox text height width min-value max-value	default-value
	      Allow the	user to	select from a range of values, e.g.,  using  a
	      slider.	The  dialog shows the current value as a bar (like the
	      gauge dialog).  Tabs or arrow keys move the cursor  between  the
	      buttons and the value.  When the cursor is on the	value, you can
	      edit it by:

	      left/right cursor	movement to select a digit to modify

	      +/-  characters to increment/decrement the digit by one

	      0	through	9
		   to set the digit to the given value

	      Some keys	are also recognized in all cursor positions:

	      home/end
		   set the value to its	maximum	or minimum

	      pageup/pagedown
		   increment the value so that the slider moves	by one column

       --tailboxbg file	height width
	      Display text from	a file in a dialog box as a  background	 task,
	      as  in  a	"tail -f &" command.  Scroll left/right	using vi-style
	      'h' and 'l', or arrow-keys.  A '0' resets	the scrolling.

	      Cdialog treats the background task specially if there are	 other
	      widgets  (--and-widget) on the screen concurrently.  Until those
	      widgets are closed (e.g.,	an "OK"), cdialog will perform all  of
	      the  tailboxbg widgets in	the same process, polling for updates.
	      You may use a tab	to traverse between the	widgets	on the screen,
	      and  close them individually, e.g., by pressing ENTER.  Once the
	      non-tailboxbg widgets are	closed,	cdialog	forks a	copy of	itself
	      into  the	 background,  and  prints its process id if the	"--no-
	      kill" option is given.

	      On exit, no text is written to cdialog's output.	Only an	"EXIT"
	      button  is provided for input, but an ESC	exit status may	be re-
	      turned.

	      NOTE: Older versions of cdialog forked immediately and attempted
	      to  update  the screen individually.  Besides being bad for per-
	      formance,	it was unworkable.  Some older scripts	may  not  work
	      properly with the	polled scheme.

       --textbox file height width
	      A	text box lets you display the contents of a text file in a di-
	      alog box.	 It is like a simple text file viewer.	The  user  can
	      move  through  the  file by using	the cursor, page-up, page-down
	      and HOME/END keys	available on most keyboards.  If the lines are
	      too  long	to be displayed	in the box, the	LEFT/RIGHT keys	can be
	      used to scroll the text region horizontally.  You	may  also  use
	      vi-style	keys h,	j, k, and l in place of	the cursor keys, and B
	      or N in place of the page-up and page-down keys.	Scroll up/down
	      using  vi-style  'k'  and	'j', or	arrow-keys.  Scroll left/right
	      using vi-style 'h' and 'l', or arrow-keys.   A  '0'  resets  the
	      left/right  scrolling.   For  more convenience, vi-style forward
	      and backward searching functions are also	provided.

	      On exit, no text is written to cdialog's output.	Only an	"EXIT"
	      button  is provided for input, but an ESC	exit status may	be re-
	      turned.

       --timebox text height [width hour minute	second]
	      A	dialog is displayed which allows you to	 select	 hour,	minute
	      and  second.  If the values for hour, minute or second are miss-
	      ing or negative, the current  date's  corresponding  values  are
	      used.   You  can	increment  or decrement	any of those using the
	      left-, up-, right- and down-arrows.  Use tab or backtab to  move
	      between windows.

	      On  exit,	 the result is printed in the form hour:minute:second.
	      The format can be	overridden using the --time-format option.

       --treeview text height width list-height	[ tag item status depth	] ...
	      Display data organized as	a tree.	 Each group of data contains a
	      tag,  the	 text  to  display  for	 the item, its status ("on" or
	      "off") and the depth of the item in the tree.

	      Only one item can	be selected (like the radiolist).  The tag  is
	      not displayed.

	      On  exit,	 the  tag of the selected item is written to cdialog's
	      output.

       --yesno text height width
	      A	yes/no dialog box of size height rows by width columns will be
	      displayed.  The string specified by text is displayed inside the
	      dialog box.  If this string is too long to fit in	one  line,  it
	      will be automatically divided into multiple lines	at appropriate
	      places.  The text	string can also	contain	the sub-string "\n" or
	      newline  characters  `\n'	 to  control line breaking explicitly.
	      This dialog box is useful	for asking questions that require  the
	      user  to answer either yes or no.	 The dialog box	has a Yes but-
	      ton and a	No button, in which the	user  can  switch  between  by
	      pressing the TAB key.

	      On exit, no text is written to cdialog's output.	In addition to
	      the "Yes"	and "No" exit codes (see DIAGNOSTICS) an ESC exit sta-
	      tus may be returned.

	      The  codes used for "Yes"	and "No" match those used for "OK" and
	      "Cancel",	internally no distinction is made.

   Obsolete Options
       --beep This was used to tell the	original cdialog that it should	make a
	      beep  when  the separate processes of the	tailboxbg widget would
	      repaint the screen.

       --beep-after
	      Beep after a user	has completed a	widget by pressing one of  the
	      buttons.

RUN-TIME CONFIGURATION
       1.  Create a sample configuration file by typing:

	      cdialog --create-rc file

       2.  At start, cdialog determines	the settings to	use as follows:

	   a)  if  environment	variable DIALOGRC is set, its value determines
	       the name	of the configuration file.

	   b)  if the file in (a) is not found,	use the	 file  $HOME/.dialogrc
	       as the configuration file.

	   c)  if  the	file  in (b) is	not found, try using the GLOBALRC file
	       determined at compile-time, i.e., /etc/dialogrc.

	   d)  if the file in (c) is not found,	use compiled in	defaults.

       3.  Edit	the sample configuration file and copy it to some  place  that
	   cdialog can find, as	stated in step 2 above.

KEY BINDINGS
       You  can	 override  or  add to key bindings in cdialog by adding	to the
       configuration file.  Cdialog's bindkey command maps single keys to  its
       internal	coding.

	      bindkey widget curses_key	dialog_key

       The  widget  name can be	"*" (all widgets), or specific widgets such as
       textbox.	 Specific widget bindings override the "*" bindings.  User-de-
       fined bindings override the built-in bindings.

       The  curses_key	can  be	 any of	the names derived from curses.h, e.g.,
       "HELP" from "KEY_HELP".	Cdialog	also recognizes	ANSI  control  charac-
       ters  such as "^A", "^?", as well as C1-controls	such as	"~A" and "~?".
       Finally,	it allows any single character to be escaped with a backslash.

       Cdialog's internal keycode names	correspond to the  DLG_KEYS_ENUM  type
       in dlg_keys.h, e.g., "HELP" from	"DLGK_HELP".

   Widget Names
       Some  widgets  (such  as	 the formbox) have an area where fields	can be
       edited.	Those are managed in a subwindow of the	widget,	and  may  have
       separate	 keybindings  from  the	main widget because the	subwindows are
       registered using	a different name.

		     Widget	   Window name	 Subwindow Name
		     -------------------------------------------
		     calendar	   calendar
		     checklist	   checklist
		     editbox	   editbox	 editbox2
		     form	   formbox	 formfield
		     fselect	   fselect	 fselect2
		     inputbox	   inputbox	 inputbox2
		     menu	   menubox	 menu
		     msgbox	   msgbox
		     pause	   pause
		     progressbox   progressbox
		     radiolist	   radiolist
		     tailbox	   tailbox
		     textbox	   textbox	 searchbox
		     timebox	   timebox
		     yesno	   yesno
		     -------------------------------------------

       Some widgets are	actually other widgets,	 using	internal  settings  to
       modify the behavior.  Those use the same	widget name as the actual wid-
       get:

			    Widget	   Actual Widget
			    -----------------------------
			    dselect	   fselect
			    infobox	   msgbox
			    inputmenu	   menu
			    mixedform	   form
			    passwordbox	   inputbox
			    passwordform   form
			    prgbox	   progressbox
			    programbox	   progressbox
			    tailboxbg	   tailbox
			    -----------------------------

   Built-in Bindings
       This manual page	does not list the key bindings for  each  widget,  be-
       cause that detailed information can be obtained by running cdialog.  If
       you have	set the	--trace	option,	cdialog	writes the key-binding	infor-
       mation for each widget as it is registered.

   Example
       Normally	cdialog	uses different keys for	navigating between the buttons
       and editing part	of a dialog versus navigating within the editing part.
       That  is,  tab  (and back-tab) traverse buttons (or between buttons and
       the editing part), while	arrow keys traverse fields within the  editing
       part.   Tabs  are  also recognized as a special case for	traversing be-
       tween widgets, e.g., when using multiple	tailboxbg widgets.

       Some users may wish to use the same key for traversing within the edit-
       ing part	as for traversing between buttons.  The	form widget is written
       to support this sort of redefinition of the keys, by adding  a  special
       group in	dlgk_keys.h for	"form" (left/right/next/prev).	Here is	an ex-
       ample binding demonstrating how to do this:

	      bindkey formfield	TAB  form_NEXT
	      bindkey formbox	TAB  form_NEXT
	      bindkey formfield	BTAB form_prev
	      bindkey formbox	BTAB form_prev

       That type of redefinition would not be useful in	other  widgets,	 e.g.,
       calendar, due to	the potentially	large number of	fields to traverse.

ENVIRONMENT
       DIALOGOPTS     Define  this variable to apply any of the	common options
		      to each widget.  Most of the common  options  are	 reset
		      before  processing  each widget.	If you set the options
		      in this environment variable, they are applied to	 cdia-
		      log's state after	the reset.  As in the "--file" option,
		      double-quotes and	backslashes are	interpreted.

		      The "--file" option is not considered  a	common	option
		      (so  you	cannot	embed it within	this environment vari-
		      able).

       DIALOGRC	      Define this variable if you want to specify the name  of
		      the configuration	file to	use.

       DIALOG_CANCEL

       DIALOG_ERROR

       DIALOG_ESC

       DIALOG_EXTRA

       DIALOG_HELP

       DIALOG_ITEM_HELP

       DIALOG_OK      Define any of these variables to change the exit code on
		      Cancel (1), error	(-1), ESC (255), Extra (3), Help  (2),
		      Help  with  --item-help  (2), or OK (0).	Normally shell
		      scripts cannot distinguish between -1 and	255.

       DIALOG_TTY     Set this variable	to "1" to provide  compatibility  with
		      older  versions  of  cdialog  which  assumed that	if the
		      script redirects the standard output, that  the  "--std-
		      out" option was given.

FILES
       $HOME/.dialogrc	   default configuration file

EXAMPLES
       The cdialog sources contain several samples of how to use the different
       box options and how they	look.  Just take a  look  into	the  directory
       samples/	of the source.

DIAGNOSTICS
       Exit  status  is	 subject to being overridden by	environment variables.
       The default values and corresponding  environment  variables  that  can
       override	them are:

       0    if the YES or OK button is pressed (DIALOG_OK).

       1    if the No or Cancel	button is pressed (DIALOG_CANCEL).

       2    if the Help	button is pressed (DIALOG_HELP),
	    except as noted below about	DIALOG_ITEM_HELP.

       3    if the Extra button	is pressed (DIALOG_EXTRA).

       4    if the Help	button is pressed,
	    and	the --item-help	option is set
	    and	the DIALOG_ITEM_HELP environment variable is set to 4.

	    While  any	of  the	exit-codes can be overridden using environment
	    variables, this special case was introduced	in  2004  to  simplify
	    compatibility.   Cdialog  uses DIALOG_ITEM_HELP(4) internally, but
	    unless the environment variable is also set, it  changes  that  to
	    DIALOG_HELP(2) on exit.

       -1   if errors occur inside cdialog (DIALOG_ERROR) or cdialog exits be-
	    cause the ESC key (DIALOG_ESC) was pressed.

PORTABILITY
       Cdialog works with X/Open curses.  However, some	 implementations  have
       deficiencies:

	  o   HPUX  curses (and	perhaps	others)	do not open the	terminal prop-
	      erly for the newterm function.  This interferes  with  cdialog's
	      --input-fd  option, by preventing	cursor-keys and	similar	escape
	      sequences	from being recognized.

	  o   NetBSD 5.1 curses	has incomplete	support	 for  wide-characters.
	      cdialog will build, but not all examples display properly.

COMPATIBILITY
       You may want to write scripts which run with other dialog "clones".

   ORIGINAL DIALOG
       First, there is the "original" dialog program to	consider (versions 0.3
       to 0.9).	 It had	some misspelled	(or inconsistent) options.  The	 cdia-
       log  program maps those deprecated options to the preferred ones.  They
       include:

	      Option	     Treatment
	      ---------------------------------
	      --beep-after   ignored
	      --guage	     mapped to --gauge
	      ---------------------------------

   XDIALOG
       Technically, "Xdialog", this is an X application.  With some  care,  it
       is possible to write useful scripts that	work with both Xdialog and di-
       alog.

       The cdialog program ignores these options which are recognized by Xdia-
       log:

	      Option		 Treatment
	      -----------------------------------------------
	      --allow-close	 ignored
	      --auto-placement	 ignored
	      --fixed-font	 ignored
	      --icon		 ignored
	      --keep-colors	 ignored
	      --no-close	 ignored
	      --no-cr-wrap	 ignored
	      --screen-center	 ignored
	      --separator	 mapped	to --separate-output
	      --smooth		 ignored
	      --under-mouse	 ignored
	      --wmclass		 ignored
	      -----------------------------------------------

       Xdialog's manpage has a section discussing its compatibility with cdia-
       log.  There are some differences	not shown in the manpage.   For	 exam-
       ple, the	html documentation states

	      Note: former Xdialog releases used the "\n" (line	feed) as a re-
	      sults separator for the checklist	widget;	this has been  changed
	      to  "/"  in Xdialog v1.5.0 to make it compatible with (c)dialog.
	      In your old scripts using	the Xdialog checklist, you  will  then
	      have  to add the --separate-output option	before the --checklist
	      one.

       Cdialog has not used a different	separator; the difference  was	likely
       due to confusion	regarding some script.

   WHIPTAIL
       Then  there  is	whiptail.  For practical purposes, it is maintained by
       Debian (very little work	is done	by its upstream	developers).  Its doc-
       umentation (README.whiptail) claims

	      whiptail(1) is a lightweight replacement for cdialog(1),
	      to provide dialog	boxes for shell	scripts.
	      It is built on the
	      newt windowing library rather than the ncurses library, allowing
	      it to be smaller in embedded environments	such as	installers,
	      rescue disks, etc.

	      whiptail is designed to be drop-in compatible with cdialog, but
	      has less features: some dialog boxes are not implemented,	such
	      as tailbox, timebox, calendarbox,	etc.

       Comparing  actual sizes (Debian testing,	2007/1/10): The	total of sizes
       for whiptail, the newt, popt and	slang libraries	is 757 KB.  The	compa-
       rable  number  for cdialog (counting ncurses) is	520 KB.	 Disregard the
       first paragraph.

       The second paragraph is misleading, since whiptail also does  not  work
       for common options of cdialog, such as the gauge	box.  whiptail is less
       compatible with cdialog than the	original mid-1990s dialog 0.4 program.

       whiptail's manpage borrows features from	cdialog, e.g., but oddly cites
       only  cdialog versions up to 0.4	(1994) as a source.  That is, its man-
       page refers to features which were borrowed from	more  recent  versions
       of cdialog, e.g.,

       o   --gauge (from 0.5)

       o   --passwordbox (from Debian changes in 1999),

       o   --default-item (from	cdialog	2000/02/22),

       o   --output-fd (from cdialog 2002/08/14).

       Somewhat	 humorously,  one may note that	the popt feature (undocumented
       in its manpage) of using	a "--" as an escape was	 documented  in	 cdia-
       log's  manpage  about a year before it was mentioned in whiptail's man-
       page.  whiptail's manpage incorrectly attributes	that to	getopt (and is
       inaccurate anyway).

       Debian uses whiptail for	the official cdialog variation.

       The  cdialog program ignores or maps these options which	are recognized
       by whiptail:

	      Option		Treatment
	      -------------------------------------------
	      --cancel-button	mapped to --cancel-label
	      --fb		ignored
	      --fullbutton	ignored
	      --no-button	mapped to --no-label
	      --nocancel	mapped to --no-cancel
	      --noitem		mapped to --no-items
	      --notags		mapped to --no-tags
	      --ok-button	mapped to --ok-label
	      --scrolltext	mapped to --scrollbar
	      --topleft		mapped to --begin 0 0
	      --yes-button	mapped to --yes-label
	      -------------------------------------------

       There are visual	differences which are not  addressed  by  command-line
       options:

       o   cdialog  centers  lists within the window.  whiptail	typically puts
	   lists against the left margin.

       o   whiptail uses angle brackets	("<" and  ">")	for  marking  buttons.
	   cdialog uses	square brackets.

       o   whiptail marks the limits of	subtitles with vertical	bars.  cdialog
	   does	not mark the limits.

       o   whiptail attempts to	mark the top/bottom cells of a scrollbar  with
	   up/down  arrows.  When it cannot do this, it	fills those cells with
	   the background color	of the scrollbar and confusing the user.  cdi-
	   alog	 uses the entire scrollbar space, thereby getting better reso-
	   lution.
