Convert apache log date format to epoch in bash

Question

My goal is to convert dates from my apache logs in the format "12/Nov/2015:23:28:22" to epoch format. Can this be done using the date command or do I need to parse and extract the information?

Answer 1

It seems my date command wants - instead of / between the date parts and that to be separated by a space from the time part. So I used sed to do the conversion like so:

date -d "$(echo '12/Nov/2015:23:28:22' | sed -e 's,/,-,g' -e 's,:, ,')" +"%s"
