how can I delete duplicates in the log?

I have a log file and I am trying to run a script against it to search for key issues such as invalid users, errors etc. In one part, I grep for session closed and get a lot of the same thing,, ie. root username etc. I want to remove the multiple root and just have it do a count, like wc -l

These are the unidentified users
auth could not identify password for [henrys]: 1 Time(s)
auth could not identify password for [henrys]: 1 Time(s)
auth could not identify password for [henrys]: 2 Time(s)
auth could not identify password for [henrys]: 1 Time(s)
Maybe a simple variable tip?
or a for i loop?
Thanks, just learning scripting.
