Awk Comparison of 2 specific files
Hi Everybody,

I know the topic sounds familiar but I just couldn't adapt or find the right code that solves my particular issue. I really hope you can help.

I would like to compare 2 files in an awk script. Both files have different paths.

The awk script call should look like that awk -f AWKSCRIPT parameter1.

The files look as follows:

File_old

Header
record1
record2
record3
Footer

File_new

Header
record1
record2
record3
Footer

First I would like to test if both files have the same amount of records.

If NO, return a code("NOMATCH") that can be further processed by a shell script. AWK Script is supposed to be called from within a bourne shell script.

If YES, please compare just the records Line by Line. I mean compare:

File_old:record1 with File_new:record1
File_old:record2 with File_new:record2

and so on...

If one of those comparisons doesn't match, return again a code("NOMATCH") that can be further processed by the calling bourne shell script. If all of the records match with on another return code("MATCH") to calling bourne shell script.

I hope I didn't describe it to complicated.

I would be very grateful for all your help.

Thanks in advance,

hhoosscchhii

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.

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

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

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

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

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

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --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.
