How To Use the scp Command on Linux
Let’s define a couple of terms: there’s SCP and there’s
scp. The uppercase SCP stands for the Secure Copy Protocol. The lowercase
scp stands for secure
cp. In other words, SCP is a protocol and
scp is a program.
scp was designed to be a safe and secure means of copying files between remote Linux computers. It uses SSH to establish secure connections. SSH, or secure shell, is a cryptographic network protocol often used to access and log in to remote Linux computers. On Linux distributions, SSH functionality is provided by OpenSSH.
