Question

I basically want to do this:

grep 'example.com' www_log > example.com.YYYY-MM-DD-H:i:S.log 

…with of course the filename being example.com.2008-09-27-11:21:30.log

I’d then put this in crontab to run daily.

Answer 1

The verbose method:

grep 'example.com' www_log > `date +example.com.%Y-%m-%d-%H:%M:%S.log` 

The terse method:

grep 'example.com' www_log > `date +example.com.%F-%T.log`
