sudo rsync -P –stats -e “ssh -i .ssh/gssa.pem” ubuntu@ip.ap-southeast-1.compute.amazonaws.com:/home/ubuntu/CORE-Ubuntu_eWRF.zip /home/fellow/

to transfer file from aws to local host

sudo rsync -avz –stats -e “ssh -i .ssh/gssa.pem” ubuntu@ecip.ap-southeast-1.compute.amazonaws.com:/home/ubuntu/sim.txt /home/fellow/

to resume a download after a net connection break

sudo rsync -P –stats -e “ssh -i .ssh/gssa.pem” ubuntu@ip.ap-southeast-1.compute.amazonaws.com:/home/ubuntu/sim.txt /home/fellow/
