Hello, I have an array that I have dumped a file into. The file contains several hundred different sentences.


The array contains, for example:

User logged in successfully at 10:35:33

User logged in successfully at 10:35:34

User logged in successfully at 10:35:35

Error: Login failure!

User logged in successfully at 10:35:37

Error: Login failure!

Error: System failure at 01:23:22

Error: System failure at 01:23:40

User logged in successfully at 10:35:39

Error: System failure at 01:23:41

So... what I've been trying to do is create a perl script to tell me how many times each error occurred.

I would need the output to look like:

User logged in successfully at 10:35:33
The above event occurred 4 additional times
Error: Login failure!
The above event occurred 1 additional times
Error: System failure at 01:23:22
The above event occurred 2 additional times

I have been trying to figure out a way to make the script count each event individually, but the for loops I have been using are only counting the first few matches.

Can someone come up with an algorithm that can count these and output the results like I have listed? Thanks for any help you can provide!
