  printf("%s\n", substr($NF, RSTART+1))
  block=0
}

vgersh, that looks pretty nice even though I can decipher very little of the actual awk code. It also works well with a couple of issues which are my fault for failing to include them in the example.

1.) The grep returns some "blank" lines, staying with my example they look like this:
Code:
--
/home/dir1/file-egress-filter-Remark : Stuff
/home/dir1/file-egress-filter-permit stuff
/home/dir1/file-egress-filter-
/home/dir1/file-egress-filter-permit other stuff
/home/dir1/file-egress-filter-
/home/dir1/file-egress-filter:permit more stuff
--
/home/dir1/other-egress-filter-
/home/dir1/other-egress-filter-Remark : Other
/home/dir1/other-egress-filter-permit other
/home/dir1/other-egress-filter-
/home/dir1/other-egress-filter-permit other others
/home/dir1/other-egress-filter:permit more other
--

The code is returning those as just the filename ie "other-egress-filter-" and I would like to return it as a truly blank line (under the header) Thoughts?

2.) Disregard 2 Smilie ... I was able to pipe information from the grep into the awk.

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. AUTHOR
