#Example syntax for Secure Copy (scp)

##What is Secure Copy?

scp allows files to be copied to, from, or between different hosts. It uses ssh for data transfer and provides the same authentication and same level of security as ssh.

###Examples

Copy the file "foobar.txt" from a remote host to the local host
