awk split numbers
I would like to split a string of numbers "1-2,4-13,16,19-20,21-25,31-32" and output these with awk into

Code:
-dFirstPage=1 -dLastPage=2 file.pdf -dFirstPage=4 -dLastPage=13 file.pdf -dFirstPage=16 -dLastPage=16 file.pdf file.pdf -dFirstPage=19 -dLastPage=20 file.pdf -dFirstPage=21 -dLastPage=25 file.pdf -dFirstPage=31 -dLastPage=32 file.pdf

When i use the script below it unsorts it into
Code:
-dFirstPage=19 -dLastPage=20 file.pdf -dFirstPage=21 -dLastPage=25 file.pdf -dFirstPage=31 -dLastPage=32 file.pdf -dFirstPage=1 -dLastPage=2 file.pdf -dFirstPage=4 -dLastPage=13 file.pdf -dFirstPage=16 -dLastPage=16 file.pdf

Code:
awk -v p="1-2,4-13,16,19-20,21-25,31-32" -v dn="file.pdf" 'BEGIN{ORS=" "; split(p,t,",");for (i in t) if(t[i] ~ /-/) {split(t[i],t1,"-"); print  "-dFirstPage=" t1[1] ,"-dLastPage=" t1[2], dn } else {print "-dFirstPage=" t[i] ,"-dLastPage=" t[i], dn }}'

What ist wrong with the script?

qpdfview

QPDFVIEW(1)						      General Commands Manual						       QPDFVIEW(1)

NAME

       qpdfview - tabbed PDF viewer

SYNOPSIS

       qpdfview [options] [file(s)[#page[#top]]]

DESCRIPTION

       qpdfview is a simple document viewer for PDF documents. It uses the poppler library for rendering.

OPTIONS

       --unique
	      If  an  instance of qpdfview is started with this option, any files that are opened using this option afterwards, are opened as tabs
	      in this same window. If a file is already opened in a tab of the respective window, it is merely reloaded using this option.

       [file(s)[#page[#top]]]
	      Specifies the files to open when qpdfview starts. If this is not specified, qpdfview will open a blank window. Multiple files can be
	      loaded  in  separate  tabs if the file names are separated by spaces. The optional parameter #page opens the file at the given page.
	      The optional parameter #top can take values between 0 and 1 and opens the page with the given position aligned to  the  top  of  the
	      tab. (See examples.)

CONFIGURATION FILE

       qpdfview uses a configuration file usually located at
	      "~/.config/qpdfview/qpdfview.conf",
       which allows configuration of the toolbars and thumbnails.

       The  keys "fileToolBar", "editToolBar" and "viewToolBar" are added to the section "mainWindow". Their values are comma-separated lists. The
       default (available) entries are:
	      fileToolBar: openInNewTab, refresh (open, saveCopy, print)
	      editToolBar: currentPage, numberOfPages, previousPage, nextPage (firstPage, lastPage, jumpToPage, search)
	      viewToolBar: scaleFactor,  zoomIn,  zoomOut  (onePage,  twoPages,  oneColumn,  twoColumns,  fitToPage,  fitToPageWidth,  doNotScale,
	      rotateLeft, rotateRight, fullscreen, presentation)
       The order of the items in the list defines the order of the items in the toolbar. (See examples.)

       Setting the keys "thumbnailWidth" and "thumbnailHeight" in the section "documentView" specifies the size of the thumbnails.

       The icon theme used by Qt can be overridden by setting the key "iconTheme" in the section "mainWindow".

EXAMPLES

	      The command
       qpdfview foo.pdf#3#0.5 bar.pdf
	      opens  foo.pdf  in the first tab with the middle of page 3 aligned to the top of the tab and bar.pdf in the second tab at the begin-
	      ning of the document.

	      Subsequent execution of the following commands
       qpdfview --unique foo.pdf bar.pdf
       qpdfview --unique foo.pdf#5
	      opens foo.pdf and bar.pdf, then reloads foo.pdf and displays its page 5.

	      Subsequent execution of the following commands
       qpdfview --unique foo.pdf
       qpdfview bar.pdf
       qpdfview --unique foo1.pdf bar1.pdf
	      opens foo.pdf in the first window, bar.pdf in a second window and then foo1.pdf and bar1.pdf in additional tabs in the first window.

	      Adding the lines
       fileToolBar=openInNewTab, refresh, saveCopy, print
       editToolBar=firstPage, previousPage, currentPage, numberOfPages, nextPage, lastPage, search
       viewToolBar=zoomOut, scaleFactor, zoomIn, oneColumn, twoColumns, rotateLeft, rotateRight
	      in section "mainWindow" of the configuration file leads to the corresponding items being displayed in the given order in	the  tool-
	      bars.
