H, Perl newb here.... I have an application log I'm trying to retrieve a specific sequence of 4 lines
from(event1, event2,event3, event4 - discarding any duplicates in between).
I've already filtered the log to get all occurances the four lines I want
but I don't know how to pull out the four lines when they happen sequentially.
EX:

09:12:50:861 EVENT1 #Don't want this line
09:13:09:467 EVENT1 #Don't want this line
09:13:09:837 EVENT1
09:13:38:059 EVENT2
09:14:03:115 EVENT3
09:14:04:076 EVENT4
09:14:11:376 EVENT1
09:14:34:049 EVENT2
09:14:34:990 EVENT3
09:14:34:990 EVENT3 #Don't want this line
09:14:34:990 EVENT4

I then need to do a time calculation between each of the four events (I can do this part....I just can't
figure out how to pull out the four lines I want everytime they appear in the sequential order I am looking for)
Can anyone help?
Thanks!
