$#array = -1
I prefer @array = () for far less magic understanding needed.
if ( $_ =~ /\Q$find\E/s ) { ... }
You can leave off the \E. And that $_ =~ would have me puzzled for a minute or two, being very non-idiomatic. Worth leaving off.
my ($final) = ( $data =~ /\G(.*)$/s ) ;
You should add /c and test the match, otherwise you'll mess up the outer loop if the match fails.
substr($str , 0 , 0) = ">>"
I prefer either $str = "$str>>" or $str =~ s/^/>>/ for that. substr gives me gas, sometimes.
my @lyb = (a..z , A..Z , 0..9) ;
That breaks under use strict, and if the begin or end point is one of the magic single-character syntax things like "q" or "s" or "y". Best to quote the begin/end points.
