Element 14 Raspberry Pi - Remote Working and Wildcards

Remote working
ssh Log in to a remote computer using Secure SHell (SSH
protocol). ssh pi@192.168.1.2 will log in as user pi on the
computer at the IP address 192.168.1.2. Note, this will only
work if the remote computer has an SSH server running.
scp Secure copy. scp file pi@192.168.1.2 :/home/pi will
copy a file to the directory home/pi on the machine with
192.168.1.2. scp pi@192.168.1.2:/home/pi/file. will
copy /home/pi/file from the machine 192.168.1.2 to
the current directory. Note, this will only work if the remote
machine has an SCP server running.
