bash script to read RDS logs

rds-logs.sh

#!/usr/bin/env/bash

$db = $1
for logfile in $(aws rds describe-db-log-files --db-instance-identifier $db | jq '.DescribeDBLogFiles|.[]|.LogFileName')
do 
  aws rds download-db-log-file-portion --db-instance-identifier $db --log-file-name ${logfile} --starting-token 0 --output text >> $db-logs.txt
done

#!/bin/bash

for x in $(aws rds describe-db-log-files --db-instance-identifier vv-qa-pgdb | jq '.DescribeDBLogFiles[].LogFileName')
do
echo "Downloading ${x}"
aws rds download-db-log-file-portion --db-instance-identifier vv-qa-pgdb --log-file-name $x --output text
done

When I am running this script I'm getting 'Downloading "LogFileName"' and 'False' in the output. Please help!
