Secure file transfer program

sftp is a command-line interface client program to transfer files using the SSH File Transfer Protocol (SFTP) as implemented by the sftp-server command by the OpenSSH project, which runs inside the encrypted Secure Shell connection.

It provides an interactive interface similar to that of traditional FTP clients.

sftp should not be confused with running an FTP client over an SSH connection.

One implementation of sftp is part of the OpenSSH project.
