I have been trying to write a script for data processing that includes a point where, based upon the input data, two threads may be running simultaneous. Then upon the closure of those two threads, the processing is again the same. I read the posting from Jan 2002, and accomplished the fork. However, I found that as soon as the script proceeds down the fork, the script finishes. The processing is done correctly, but I not until after the script has finished.

Essentially, this is the structure: 

`command one *`
`command two *`
if (file =~ AAA) {
   `command four option1 file`
   &finish
   }elsif (file =~ BBB) {
   `command four option2 file`
   &finish
   }

`command five`

sub finish {
    `command six`
     }

I find that command five runs three times. I would expect it to only run once. All files will be of either AAA or BBB, but not both. The finish subroutine will run twice for files of type BBB and once for type AAA.

What did I screw up?
