Hi, I posted something similar last week but didn't properly explain what I needed to do and
I still can not figure it out. I have an application log I'm trying to retrieve a specific sequence of 4 lines
from(event1,event2,event3, event4). I've successfully filtered the log to get all occurances the four lines
but now only want to pull out the blocks of lines where the events occur in sequence.
EX:

09:12:50:861 EVENT1 #discard
09:13:09:467 EVENT2 #discard
09:13:09:837 EVENT1 #keep
09:13:38:059 EVENT2 #keep
09:14:03:115 EVENT3 #keep
09:14:04:076 EVENT4 #keep
09:14:11:376 EVENT1 #discard
09:14:34:049 EVENT2 #discard
09:14:34:990 EVENT3 #discard
09:14:34:990 EVENT3 #discard
09:14:34:990 EVENT4 #discard
09:15:09:837 EVENT1 #keep
09:16:38:059 EVENT2 #keep
09:17:03:115 EVENT3 #keep
09:18:04:076 EVENT4 #keep

I want to extract the data when the four events happen in an unbroken sequence and print them to a file
Can anyone help me? I'm fairly new to Perl and development in general.
Thanks again!
