Hi, In windows I am using a nice piece of perl code to tail a log file. It does a nice job until the file becomes very large, ie over 20 meg, then the perl process starts to be a memory hog. I tried using a cygwin tail, but it locks the file so the original process can't write to it. This perl code does NOT lock the file. Can someone suggest how I might grab new chunks of a large file efficiently ? The current code is like this 
while(-s $file ) {
  open(TF,$file) || last ;
  seek(TF,$curpos,0);
  @lines=<TF>;
  $cursorposition = tell(TF);
  last if ((stat(_))[7] < $cursorposition);
    foreach $nline (@lines){
    $newline = substr $nline, 24;
    # write out to tailfile    $newline
    }    
  close(TF);
  sleep 1;
}
}
else
    { sleep 5; }
}
