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,
