scpg3 (sshg3.exe on Windows) is used to securely copy files over the network. scpg3 launches ssh-broker-g3 to provide a secure transport using the Secure Shell version 2 protocol. The remote host(s) must be running a Secure Shell version 2 server with the sftp-server subsystem enabled.

The basic syntax of scpg3 is:

scpg3 user@source:/directory/file user@destination:/directory/file

scpg3 can be used to copy files in either direction; from the local system to the remote system or vice versa. Copies between two remote hosts are also permitted. Local paths can be specified without the user@system: prefix. Relative paths can also be used, they are interpreted in relation to the user's home directory.
