grep may not be the best tool for matching a range of timeswhat is the best tool
How tolerant are you of matching more than requested? Do you mind getting all of yesterday, or all of today?my requirement keep changing. tomorrow i may want to search on whole last week data or whole last month date.
How about missing yesterday from 11pm to 11:59:59?
any perfect examples to tweak those example queries?
