If you're retrieving all filenames using opendir and readdir (which is the way I usually do it), then you'll want to filter out at least directories (and possibly smylinks as well)
Here's one way to do it (modified from example in The Perl Cookbook):
$dir = 'path/to/directory';
opendir(DIR, $dir) or dir "Can't open $dir: $!";
while (defined($file = readdir DIR)) {
#Test if $file is a directory
unless (-d "$dir/$file") {
#Test if $file is a symlink
unless (-l "$dir/$file") {
#push $file onto @list
push(@list,$file);
}
}
}
