Redmine production.log to uri log

But.. It doesn't work well. (Because the sequence of line is not arranged.)
It is better way to use 'redmine_access_logger' plugin than this

#!/bin/bash

# Setting
LOG_FILE=/redmine-3.3.3/log/production.log
#LOG_FILE=mylog.log
PIDFILE=/var/run/redmine_info_log.pid

# Program Variables
OUTPUT_LOGDIR=`dirname ${LOG_FILE}`

OPT_DEBUG=0
URI_FILTER_REGEX="(^\"/people/avatar)|(^/attachments/thumbnail/)|(^\"/issues/.*\.xml)"

function echo_log()
{
  if [ "$2" != "" ]; then
    echo "$1" >> $2
  else
    echo "$1"
  fi
}


if [ -f $PIDFILE ]
then
  PID=$(cat $PIDFILE)
  ps -p $PID > /dev/null 2>&1
  if [ $? -eq 0 ]
  then
    echo "Process already running"
    exit 1
  else
    ## Process not found assume not running
    echo $$ > $PIDFILE
    if [ $? -ne 0 ]
    then
      echo "Could not create PID file"
      exit 1
    fi

  then
