Problem with case 1, I think, is that "next if (/^\./);" compares to
$_, not $file. Should be:
foreach my $file (readdir(DIR)) {
next if ($file =~ /^\./);
}
Problem with case 2, I think, is that you need to provide a full path
name to -d:
foreach my $file (readdir(DIR)) {
next if (-d "$dir\\$file");
}
Keep in mind that I'm using \ as a separator, which should be / for Unix/Linux.
Also, -d $file might work if you know that the current directory is
$dir, but it seems
safer to me to just give a full path name.
