       gdialog - display dialog boxes from shell scripts

       gdialog --clear
       gdialog --create-rc file
       gdialog [ --title title ] [ --backtitle backtitle ] [ --clear ] [ --separate-output ] box-

       Gdialog is a program that will let you to present a variety of questions or  display  mes-
       sages  using  dialog boxes from a shell script. Currently, these types of dialog boxes are

       yes/no box, menu box, input box, message box, text box, info box, checklist box, radiolist
       box and gauge box.

       This  program  is  much	like the dialog program, but along with displaying textual dialog
       boxes if the environment variable DISPLAY is unset, if the environment variable is set  it
       will instead display graphical dialog boxes using gtk/gnome.

	      The screen will be cleared to the screen attribute on exit.

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

	      For checklist widgets, output result one line at a time,	with  no  quoting.   This
	      facilitates parsing by another program.

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

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

       Box Options

       --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 be fitted in one line, it will be automatically divided into multiple lines
	      at appropriate places. The text string may also contain the sub-string "\n" or new-
	      line characters `\n' to control line breaking explicitly.  This dialog box is  use-
	      ful  for	asking	questions  that require the user to answer either yes or no.  The
	      dialog box has a Yes button and a No button, in which the user can  switch  between
	      by pressing the TAB key.

       --msgbox text height width
	      A  message box is very similar to a yes/no box.  The only difference between a mes-
	      sage 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 mes-
	      sage, the user can press the ENTER key so that dialog will  exit	and  the  calling
	      shell script can continue its operation.

       --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.

       --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 inputing the string, the BACKSPACE key can be used to correct
	      typing errors. If the input string is longer than can be fitted in the dialog  box,
	      the  input  field  will  be  scrolled. On exit, the input string will be printed on

       --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 UP/DOWN,
	      PGUP/PGDN 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. For more convenience, forward and backward searching functions
	      are also provided.

       --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. 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 UP/DOWN 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. When dialog  exits,  the
	      tag of the chosen menu entry will be printed on stderr.

       --checklist text height width list-height [ tag item status ] ...
	      A  checklist  box  is similar to a menu box in that there are multiple entries pre-
	      sented 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 specified by status.  On exit, a list of the tag strings of those  entries  that
	      are turned on will be printed on stderr.

       --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.

       --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 stdin is XXX, then  subse-
	      quent  lines up to another XXX are used for a new prompt.  The gauge exits when EOF
	      is reached on stdin.

       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, it's value determines  the  name  of  the
	       configuration file.

	   b)  if  the file in (a) can't be found, use the file $HOME/.dialogrc as the configura-
	       tion file.

	   c)  if the file in (b) can't be 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.

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

       $HOME/.dialogrc	   default configuration file

       Exit status is 0 if dialog is exited by pressing the Yes or OK button, and 1 if the No  or
       Cancel  button is pressed. Otherwise, if errors occur inside dialog or dialog is exited by
       pressing the ESC key, the exit status is -1.

       Text files containing tab characters may cause problems with text box.  Tab characters  in
       text files must first be expanded to spaces before being displayed by text box.

       Screen update is too slow.
