Secure Copy Protocol (SCP) is a widely used method for securely transferring files between remote hosts. It provides authentication and encryption, ensuring that sensitive data remains protected during transit. In the context of Raspberry Pi, SCP can be a valuable tool for transferring files securely between the Pi and other devices on the network. This article will guide you through the process of using SCP on Raspberry Pi, highlighting any adjustments or considerations specific to this environment.

Examples:

1. Copying a file from Raspberry Pi to a remote host: To copy a file named "example.txt" from Raspberry Pi to a remote host, use the following command:

   scp /path/to/example.txt username@remote_host:/path/to/destination

   Replace "/path/to/example.txt" with the actual path of the file on Raspberry Pi, "username" with your username on the remote host, "remote_host" with the IP address or hostname of the remote host, and "/path/to/destination" with the desired destination path on the remote host.

2. Copying a file from a remote host to Raspberry Pi: To copy a file named "example.txt" from a remote host to Raspberry Pi, use the following command:

   scp username@remote_host:/path/to/example.txt /path/to/destination

   Replace "username" with your username on the remote host, "remote_host" with the IP address or hostname of the remote host, "/path/to/example.txt" with the actual path of the file on the remote host, and "/path/to/destination" with the desired destination path on Raspberry Pi.

3. Copying a directory from Raspberry Pi to a remote host: To copy a directory named "example_directory" from Raspberry Pi to a remote host, use the following command:

   scp -r /path/to/example_directory username@remote_host:/path/to/destination

   Replace "/path/to/example_directory" with the actual path of the directory on Raspberry Pi, "username" with your username on the remote host, "remote_host" with the IP address or hostname of the remote host, and "/path/to/destination" with the desired destination path on the remote host.
