I don't think those do what you think they do. Here are some options:
use File::Find;
#print all entries at or below starting dir:
find ( sub { print $File::Find::name,"\n" }, '.' );
#print all directories at or below starting dir:
find ( sub { next unless -d; print $File::Find::name,"\n"; }, '.' );
#print all entries, trailing directories with a '/':
find ( sub { print $File::Find::name,(-d $_ ? '/' : ''),"\n" },'.' );
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
