DIALOG(1)                                                            DIALOG(1)




NAME

       dialog - display dialog boxes from shell scripts


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, form, fselect,  gauge,  infobox,  inputbox,
              inputmenu,  menu,  msgbox (message), password, pause, 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
            nonzero, 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
       using 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,
       replacing  "--file"  and  its option value.  Interpretation of the com-
       mand-line resumes from that point.

   Common Options
       --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:
                 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".

       --cr-wrap
              Interpret  embedded  newlines in the dialog text as a newline on
              the screen.  Otherwise, dialog will only wrap lines where needed
              to  fit  inside  the text box.  Even though you can control line
              breaks with this, dialog 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 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
              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 dialog
              scripts read from the standard input, but the gauge widget reads
              a pipe (which is always standard input).  Some configurations do
              not work properly when dialog tries to reopen the terminal.  Use
              this option (with appropriate juggling of  file-descriptors)  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.

       --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-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-shadow
              Suppress  shadows that would be drawn to the right and bottom of
              each dialog box.

       --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.

       --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.

       --separator string

       --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).

       --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,
              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.   Otherwise,
              tabs  are rendered according to the curses library’s interpreta-
              tion.

       --tab-len n
              Specify the number of spaces that a tab  character  occupies  if
              the "--tab-correct" option is given.  The default is 8.

       --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.

       --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:

       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.

       --calendar text height width day month year
              A  calendar  box  displays  month,  day  and  year in separately
              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.

       --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.

              -  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  file-selection dialog displays a text-entry window in which
              you can type a filename (or directory), and above that two  win-
              dows 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.

              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 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 dialog’s output.  The widget
              accepts 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,
              dialog will exit immediately after displaying the message to the
              user.  The screen is not cleared when dialog 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 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.

       --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.

              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 (status OK) or
              the user presses the Exit button (status CANCEL).

       --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.

       --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  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.

       --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.

       --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 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.


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 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.

       3    if the Extra button is pressed.

       -1   if  errors occur inside dialog or dialog is exited by pressing the
            ESC key.
