At this point, I'd like to change the menu to do this:

cat /var/log/secure |grep -i 'could not identify password' |awk '{print $1,$2,$3

I want it to cat the files and grep for certain items? Do I need another read statement? What should it be? I'd like to get this done today, as my meeting is in 4 hours. Any help would be appreciated. I tried this and it didn't work:
