full backups

Hi Champs,

I have created a command to find out which clients have full backups.

I do have the list of clients now.

Below is my command:

for i in `cat allvm.txt`;do ./bpimagelist -d 05/01/2019 00:00:00 -e 05/23/2019 00:00:00 -client $i -l; done|awk '/^IMAGE/ {print $2, $7, $11}'|egrep -i "week|Full"|awk '!a[$0]++'

now i need some modification in this  command so that it gives me what all clients  do not have a good FUll backup in the defined time stamp.

Thanks in advance
