If your directory name is something like
My Silly Folder Name (i.e. four words, three spaces), then you must put quotes around the full name on the command line when you run the perl script -- otherwise, the shell will pass the name to perl's @ARGV as four separate args (that is:
@ARGV[0..3]).
I guess another way to handle this (without qouting the directory name on the command line) might be:
my $root_dir = join " ", @ARGV;
In any case, your attempts at putting quotes around $ARGV[0] have no effect at all on the issue.
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.
