( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Hi,

Thanks everyone for your offer to help. I've posted below a complete program that runs on my system. Where it encounters an error and quits, it displays the following, with a few of the preceding lines:

bucket: aa type: spam 2012-07-02 20120702T132446 bucket: aa type: spam 2012-07-07 20120707T083754 bucket: aa type: spam 2012-07-02 20120702T203543 bucket: aa type: virus 2012-07-08 20120708T113543 bucket: aa type: spam 2012-07-16 20120716T151849 bucket: aa type: virus 2012-07-22 20120722T100147 bucket: aa type: spam 2012-07-03 20120703T042249 bucket: aa type: spam 2012-07-07 20120707T204829 Use of uninitialized value in split at ./list_hash.pl line 32. Use of uninitialized value $dt in pattern match (m//) at ./list_hash.p +l line 35. key 2 not defined. Deleting.

It's reading from 255 hashes for each host, which you aren't going to have, so it probably won't execute for you.

As I mentioned previously, the delete() isn't actually deleting for some reason. If I run the program again, it dies at the same spot, indicating to me that the record with the undef'd value or key still remained.

Any ideas greatly appreciated.
