while ($filename = readdir DIR)You are using readdir in a scalar context,
but grep operates on an array/list. so if you want to utilize grep(),
this probably will get from the current directory all .html files that
is less than a day old:
my @html_files = grep { /\.html$/i && -M $_ < 1 } readdir DIR ;
Here readdir is used in a list context.
