It would be better so see the example you are working on. For me personally, this is just a bit abstract. By all means, sanitise it to remove anything sensitive, but it would be useful to know.

If you are simply looking for a vi command to replace strings in a specific range of rows in a file (i.e. your script) then if you place the cursor at the start line of the range and press CNTL-G, you will get the line number displayed, e.g. line 123. Do the same at the end and let's say that tells you it's line 456. You can then issue something like:-
Code:
:123,456 s/searchstring/replacestring/

This will replace between lines 123 to 456 inclusive the first occurence on each line. If you want every occurrence on each line, then it's:-
Code:
:123,456 s/searchstring/replacestring/g


I hope that this helps, but if I've missed the point, please explain more of what you want to acheive and show us the source.

Is the script beyond a re-design where you write this as a function and pass in the parameters to test/respond with?

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.
	      Please notice this option isn't related to the terminal length as in a "80 culums terminal".

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do right to left (RTL) layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.

       Postscript points
	      Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.

       --bottom-margin=bm
	      Set bottom margin. Default is 36 postscript points.

       --top-margin=tm
	      Set top margin. Default is 36 postscript points.

       --left-margin=lm
	      Set left margin. Default is 36 postscript points.

       --right-margin=rm
	      Set right margin. Default is 36 postscript points.

       --gutter-width=gw
	      Set gutter width. Default is 40 postscript points.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
