Automatically download files via SSH without password

download.sh

#!/usr/bin/bash

# Download CSV files from Linux server (iny my case, Raspberry Pi and Ubuntu)
# over SSH without the need to supply password. Note that Cygwin have to be
# used with this file since Git Bash uses other keyfiles.
#
# 1.Upload keyfiles:
# scp /home/username/.ssh/id_rsa.pub [email protected]:~/.ssh/authorized_keys2
# 2. Don't forget to make file executable:
# chmod +x download.sh

echo "Downloading from Raspberry Pi..."
scp [email protected]:/home/pi/*.csv /local-dir
