And what is your OS and version of these unix log servers?

Try:
Code:
grep "$( date -d '1 day ago' +'%Y/%m/%d' )" /var/log/messages

Note: This will work only if you have GNU date

I also noticed that you mentioned: Dates are in the format "YYYY-MM-DD"

Then you have to change format to +'%Y-%m-%d'
