RE: removing an empty directory

Do you know how to test
for the existence of an empty directory?

thanks,

John

Thanks,

I found out, that I need to add the full path
to the file $directoryempty = $searchdrive1 . $directoryempty;

regards,

John

#put this after your rmdir
print Win32::FormatMessage(Win32::GetLastError())."\n";

# or add $! To your warn statement

They will tell you why it thinks it didn't work.. $! Numerically, and
the print statement formatted.  You could probably combine the
FormatMessage with $! As well, though I haven't tried.

Hello,

I was wondering if anyone would know
why rmdir wouldn't remove an empty directory?

This is the code that I'm using:

use strict;

my $directoryempty = undef;
my $searchdrive1 = 'I:\\';

opendir(EMPTYDIR, $searchdrive1) ;
       while($directoryempty  = readdir(EMPTYDIR) ) {
           chomp $directoryempty;
           rmdir ("$directoryempty") || warn "Cannot remove directory
$directoryempty\n";
         }

thanks,

John
