CC avizit, if you give a sample of the log this is likely very simple.

I am not sure why you would want to use awk right away. If you are only interested in number of logins  it is much faster and easier to do a grep and wc:

grep kaushalinder radius.log|grep '6-8-2004'|wc -l

This will give you the number of lines in radius.log which contain kaushalinder and 6-8-2004.

OK... If you have a log file (radius.log) and you want to filter the log based on username and dates and return how many times the person logged in, you would not need awk.

Use grep, like so:

cat radius.log | grep <date format> | grep <username> | wc -l

This will return the number of lines in the log, filtered by the date and username given.

You can even do a:

grep -c <username>

instead of:

grep <username> | wc -l
