Code:
du: cannot access `LOGS_18-08-20.tar.gz': No such file or directory

below is snippet of script
Code:
cd /home
dt=$(date --date="yesterday" +"%y-%m-%d")
du  "LOGS_$dt.tar.gz"

Is LOGS_18-08-20.tar.gz in /home?
What do you get when you type
Code:
echo /home/LOGS_*.gz

The file is /home/LOGS_2018-08-20.tar.gz and you are looking for /home/LOGS_18-08-20.tar.gz. Change the %y in your script to %Y and try again.
