Previous log and diff
Logs are created on a daily basis, the format of the log file is: servername_yymmdd. I need to check if there is a difference in the log created today with the previous one. I would appreciate help on how I can step back to the previous log and how can I test if there is a diff in the logs.

Thanks you.

There are dozens of examples finding yesterday's date on the forum. Try a search, or go to the FAQ and look up the thread on date arithmetic - datecalc script

Code:
date -d "yesterday" +"%d %b %Y"
