Spindoctor,
A picture is worth a thousand of words.
The ideal would be for a sample of what you described.
In any event, here is one way to solve what I understood
you said:
Code:
mREa='/Author/,/\\/p'
mREb='s/.*:\(.*\)/\1/'
mREc='s;\\;;'
mREd='s/^ *\(.*\)/\1/'
mREe='/^$/d'
for mFile in *
do
  echo "Now working with file = <"$mFile">"
  egrep 'Author' $mFile | sed -n "$mREa" | sed -e "$mREb" -e "$mREc" -e "$mREd" -e "$mREe"
done

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

	%install
	    shtool subst -v -n

		-e 's;^(sysconfdir=).*;1 $RPM_BUILD_ROOT%{_prefix}/etc;g'

HISTORY

       The GNU shtool subst command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 2001 for GNU shtool.  It was prompted
       by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.

SEE ALSO

       shtool(1), sed(1).
