Oh esteemed Monks, I come to you once again.

I have a file that has this output in it:


L01783 NETAPP-DAILY CLOSED-C5
L01456 WIN-DAILY CLOSED-C5
L00378 NETAPP-DAILY CLOSED-C5
L01799 NETAPP-DAILY CLOSED-C5
L00543 NETAPP-WEEKLY CLOSED-C5
L01458 WIN-DAILY CLOSED-C5
L01459 UNIX-DAILY CLOSED-C5
L01797 NETAPP-MONTHLY PROGRAM-P5
L01431 NETAPP-DAILY CLOSED-C5
L00425 WIN-WEEKLY CLOSED-C5
L00277 NETAPP-MONTHLY CLOSED-C5
L00588 UNIX-DAILY CLOSED-C5
L01468 NETAPP-DAILY CLOSED-C5
L01780 UNIX-DAILY CLOSED-C5
L01782 NETAPP-MONTHLY PROGRAM-P5
L01288 NETAPP-WEEKLY CLOSED-C5
L01293 NETAPP-MONTHLY PROGRAM-P5
L01784 NETAPP-MONTHLY PROGRAM-P5
L01121 NETAPP-DAILY CLOSED-C5

I have a hash called %tapes. The key in this hash is L001121 and the value is NETAPP-DAILY CLOSED-C5. (One key/value for each line in the file.)

What I need to do is output a new file after removing some lines. I can do this just fine, but I have a sorting problem. I need to sort this has based on the "C5" and "P5" parts. So the final data should look like this:

L01783 NETAPP-DAILY CLOSED-C5
L01456 WIN-DAILY CLOSED-C5
L00378 NETAPP-DAILY CLOSED-C5
L01799 NETAPP-DAILY CLOSED-C5
L00543 NETAPP-WEEKLY CLOSED-C5
L01458 WIN-DAILY CLOSED-C5
L01459 UNIX-DAILY CLOSED-C5
L01431 NETAPP-DAILY CLOSED-C5
L00425 WIN-WEEKLY CLOSED-C5
L00277 NETAPP-MONTHLY CLOSED-C5
L00588 UNIX-DAILY CLOSED-C5
L01468 NETAPP-DAILY CLOSED-C5
L01780 UNIX-DAILY CLOSED-C5
L01288 NETAPP-WEEKLY CLOSED-C5
L01121 NETAPP-DAILY CLOSED-C5
L01797 NETAPP-MONTHLY PROGRAM-P5
L01782 NETAPP-MONTHLY PROGRAM-P5
L01293 NETAPP-MONTHLY PROGRAM-P5
L01784 NETAPP-MONTHLY PROGRAM-P5

Thanks in advance for your help!
Thanks so much to everyone! I don't know why I didn't think of using substr to compare the values, I guess I just need more experience programming perl. Anyway, this was a huge help and now I've got it working perfectly. Thanks again!
