How do I get a bash script to print out to my putty console when run. I thought I am supposed to use Echo but My script below only gives me a blank terminal when executed yet still works as planned?

#!/bin/bash

exec 3>&1 4>&2
trap 'exec 2>&4 1>&3' 0 1 2 3
if [ -e /var/log/s3extractLog.log ]
then
    exec 1>>/var/log/s3extractLog.log 2>&1
else
    touch /var/log/s3extractLog.log
    exec 1>>/var/log/s3extractLog.log 2>&1
fi
