..yeah, but if you start a command string with the wrong syntax, you are never going to get the output you are expecting. In this case, grep must grep the string from something, being a file or an output.

I take it is a log file that's logging the user activity, and this log file has a date stamp that includes the month. If that is the case, then the command should be:
Code:
 grep $b logfile

... then you can pipe the output of that command to last, then awk.

tNow, I think you are making things a little more complicated than they need to be.
Why don't you post a sample output from the log file and show us what you are trying to compare?

BTW, use code tags. They make your output and code more readable.
