SCP Download from a Specific Directory

See more SCP Examples

Demonstrates how to download a file using the SCP protocol (Secure Copy Protocol over SSH), from a specific remote directory located on the SSH server. The remote directory can be a path relative to the HOME directory of the SSH user account, or an absolute path on the remote filesystem. Obviously, in both cases the SSH user account must have permission to open and read the file in the specified directory. Lianja
