Re^2: File APPEND/OVERWRITE

I tried the "or die" and the files all seem to be opening fine...(no death notices.. :-)

I am wondering about something...earlier in my code, I have a line of code to do a "mkdir", which I assumed would act the same as if I was doing it by hand...i.e. if a mkdir is entered on a subdirectory that already exists, it will just go in with life...:

foreach (@text) {
   $first = substr($_,0,11);
   mkdir "$first";
   print "Copying $_ to $first.\n";
   copy($_,"$first/$_");
   unlink $_;
     }

I am wondering if that "mkdir" is actually re-creating the sub-directories, which if so I guess would wipe out anything that was in there previously?
