If you will be running this script multiple times, each run will overwrite the previously saved ppid.

If you want to preserve/append to the PPID instead, use this construct to open the file in "append" mode: 

open my $wfh, '>>', "$dir/$outfile"
  or die "ERROR: Can't open/append the damned output file! The OS says
+:$!";
