I think that what you're proposing is a little bit too specialized to 
merit its own utility.  Of course, this is just my opinion.  I write a 
*lot* of these sorts of things... 

I would have coded this thusly: 

  perl -lne 'print "some pretty formating text $1" if (/Title:*\[ISBN:\s*(\d+)\]/)' file1 file2 ... 

or, if you were using Perl 5.10 (or newer), you could name the 
backreference thusly: 

  perl -lne 'print "some pretty formating text $+{isbn_number}" if (/Title:*\[ISBN:\s*(?<isbn_number>\d+)\]/)' file1 file2 ... 

Kind regards,
