Hi,
I am attempting to batch access the contents of a group of directories (within a parent directory) but am having trouble getting the -d directory testing flag to work. A snippet of my code follows:

opendir(DIR,$DirName);
while(my $SubDir = readdir(DIR)) {
next if $SubDir =~ /^\./;
if (-d $SubDir) {
... work on contents of sub-directory
}
}

The problem is that my subdirectories in DIR are not being seen as directories and I can't go on. I have specified a full path to $DirName and the -d test still doesn't work.
Thanks in advance for any help,
N.

opendir(DIR,$DirName); 
while(my $SubDir = readdir(DIR)) { 
  next if $SubDir =~ /^\./; 
  if (-d "$DirName/$SubDir") { 
    ... work on contents of sub-directory 
  } 
}
