It may run for a while if your log file is large. I'm not sure how to tell it to only process a specific number of lines. You can pipe it to tail to view the end if that is all you want to look at, but the process is still going to run, eating CPU cycles until it gets to the end of the file. Maybe someone knows how to run this more efficiently.
indiana_tas, this is great in fact but using tail brings to the terminal some coded info so I prefer as it is more simple to use who. Piped I could do this:

Code:
# who /etc/security/failedlogin | tail -1

Which shows just the very last line of the file.
