Hi, gather a count of all of the lines that are the same
You may have to check each of the lines, because not all the lines are the same. e.g 

User logged in successfully at 10:35:33
User logged in successfully at 10:35:34
User logged in successfully at 10:35:35
User logged in successfully at 10:35:37

[download]
The lines above are not the same, because of the changing time the user logged in.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
