Overview

Simple patch to DateRoller which uses the previous day’s date for the rolled filename

oneliner to fix incorrect dates from previously rolled files: ruby -rtime -e ‘`ls .2.log`.split(“n”).each{ |f| f =~ /(2015d+)/; d = $1; dd = (Time.parse(d)-86400).strftime(“%Y%m%d”); File.rename(f, f.gsub(/#d/, dd)) }’
