dialog


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

DESCRIPTION
       Dialog is a program that will let you to 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 dialog):

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

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

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

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

       Some  widgets,  e.g.,  checklist,  will  write text to dialog'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; dialog 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.
              dialog --title -- --Not an option

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

       The "--file" option tells dialog to read parameters from the file named
       as its value.
              dialog --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 "&", dialog
              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:
              dialog                         --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:
              dialog           --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:
              dialog           --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:
              dialog           --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 dialog  to  set  colors  or  video
              attributes: 0 through 7 are the ANSI used in curses: black, red,
              green, yellow, blue, magenta, cyan and white respectively.  Bold
              is  set  by  'b', reset by 'B'.  Reverse is set by 'r', reset by
              'R'.  Underline is set by 'u', reset by 'U'.  The  settings  are
              cumulative,  e.g.,  "\Zb\Z1" makes the following text bold (per-
              haps bright) red.  Restore normal settings with "\Zn".
              your  text  may  be formatted to look nice in the source code of
              your script without affecting the way it will look in  the  dia-
              log.

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

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

       --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
              options  overrides  this, making the default button always "Yes"
              (internally the same as "OK").

       --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 dialog's output.  The help message is
              printed if no options are given.

       --help-button
              Show  a  help-button  after  "OK" and "Cancel" buttons, i.e., in
              checklist, radiolist and menu boxes.  If "--item-help"  is  also
              given,  on  exit  the  return status will be the same as for the
              "OK" button, and the item-help text will be written to  dialog's
              output  after  the  token  "HELP".  Otherwise, the return status
              will indicate that the Help button was pressed, and  no  message
              printed.

       --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.

       --ignore
              Ignore options that dialog does not recognize.  Some  well-known
              Makes the password widget friendlier but less secure, by echoing
              asterisks for each character.

       --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
              Normally dialog checks to see if it is running in an xterm,  and
              in  that  case tries to suppress the initialization 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 dialog several  times.   Use  this  option  to
              allow dialog to use those initialization strings.

       --keep-window
              Normally  when  dialog  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, dialog 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.

       --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 dialog 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 dialog will still wrap text, subject to the "--cr-wrap" and
              "--trim" options.

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

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

       --no-lines

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

       --output-fd fd
              Direct output to the given file descriptor.  Most dialog 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 dialog'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 dialog's output.  This  may  be  used  alone,  without  other
              options.

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

       --print-version
              Prints  dialog's  version  to dialog's output.  This may be used
              alone, without other options.

       --separate-output
              For checklist widgets, output result 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 dialog's out-
              put from each widget.  This is  used  to  simplify  parsing  the
              result  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, dialog uses double quotes around  each  item.
              That  requires  occasional use of backslashes to make the output
              useful 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).
              scripts  is  not  recommended,  since curses normally writes its
              screen updates to the standard output.  If you use this  option,
              dialog  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.

       --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.

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

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

       --trace filename
              logs keystrokes to the given file.  Use control/T to log a  pic-
              ture of the current dialog window.

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

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

       --version
              Same as "--print-version".

       --visit-items
              Modify the tab-traversal of  checklist,  radiobox,  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:

              adjustable  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.

       --checklist text height width list-height [ tag item status ] ...
              A  checklist  box  is  similar to a menu box; there are multiple
              entries presented in the form of a menu.   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  speci-
              fied by status.

              On  exit,  a  list  of the tag strings of those entries that are
              turned on will be printed on dialog's output.  If  the  "--sepa-
              rate-output"  option is not given, the strings will be quoted to
              make it simple for scripts to separate them.  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
              dialog'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
              --inputbox,  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.
              -  If  flen  is zero, the corresponding field cannot be altered.
                 and the contents of the field determine the displayed-length.

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

              -  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 dialog's
              output, each field separated by a newline.   The  text  used  to
              fill non-editable fields (flen is zero or negative) is not writ-
              ten 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
              directory  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 dialog to complete the current
              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
              dialog'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.
              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 dialog's output.   Only  an  "OK"
              button  is  provided  for  input,  but an ESC exit status may be
              returned.

       --inputbox text height width [init]
              An input box is useful when  you  want  to  ask  questions  that
              require  the  user  to input a string as the answer.  If init is
              supplied it is used to initialize the input string.  When enter-
              ing  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 dialog'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
                  adjusted.

              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 dialog will write the following on dia-
                  log'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
              entries by pressing the cursor keys, the first letter of the tag
              as  a  hot-key,  or  the  number keys 1-9. 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 dia-
              log'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 ] ...

              It also displays a list of the tag- and item-values at  the  top
              of the box.  See dialog(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 dialog's output.  The widget
              accepts 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 dialog will  exit  and  the
              calling shell script can continue its operation.

              If  the message is too large for the space, dialog 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 dialog's output.   Only  an  "OK"
              button  is  provided  for  input,  but an ESC exit status may be
              returned.

       --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 dialog'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.

       --progressbox text height width

              On exit, the name of the selected item is  written  to  dialog'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 dialog's output.  Only an "OK"
              button is provided for input, but an  ESC  exit  status  may  be
              returned.

       --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.

              Dialog  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"), dialog 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, dialog 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 dialog's output.  Only an "EXIT"
              button is provided for input, but an  ESC  exit  status  may  be
              returned.

              NOTE:  Older versions of dialog 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
              dialog 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, 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 dialog's output.  Only an "EXIT"
              button is provided for input, but an  ESC  exit  status  may  be
              returned.
              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 dialog'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:

                 "dialog --create-rc <file>"

       2.  At start, dialog 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
           dialog can find, as stated in step 2 above.

KEY BINDINGS
       You can override or add to key bindings in dialog by adding to the con-
       figuration file.  Dialog'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
       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  dia-
                      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  dialog  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  dialog 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.
       Normally they are:

       0    if dialog is exited by pressing the Yes or OK button.

       1    if the No or Cancel button is pressed.

       2    if the Help button is pressed.

       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
       dialog.

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

              Option             Treatment
              -----------------------------------------------

              --wmclass          ignored

       Xdialog's  manpage has a section discussing its compatibility with dia-
       log.

   WHIPTAIL
       Then there is whiptail.  For practical purposes, it  is  maintained  by
       Debian.  Its documentation claims

              whiptail(1) is a lightweight replacement for dialog(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 enviroments such as installers,
              rescue disks, etc.

              whiptail is designed to be drop-in compatible with dialog, 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 757kb.  The  compa-
       rable  number  for  dialog  (counting ncurses) is 520kb.  Disregard the
       first paragraph.

       The second paragraph is misleading, since whiptail also does  not  work
       for  common options of dialog, such as the gauge box.  whiptail is less
       Debian uses whiptail for the official dialog variation.

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

              Option         Treatment
              -------------------------------------
              --fb           ignored
              --fullbutton   ignored
              --nocancel     mapped to --no-cancel
              --noitem       ignored
