Shell Programming and Scripting

I have this script that will increase my entered date, seven days. I need to add something to this script (i don't know how to do it) that will search a log file doing a word count for the words password and change and put that output to a file. then again for the next date and so on and so on. The log files being searched begin with the date (example 2010-10-31......) and have a time stamp after it.

So i need it to read the date (which I have), search that dated log file (which I don't have) increase the date and do it again, 7 times.

Please help. I am looking to use the date in a grep before it changes, then use it again, etc...

Code:

echo "Enter date[mm/dd/yyyy]: "
read date
echo $date | ruby -e 'require "date";d,m,y=gets.chomp.split("/");t=Date.new(y.to_i,d.to_i,m.to_i);1.upto(7){|x|p t.to_s;t+=1}'
