The sftp command is a secure alternative to ftp and is functionally the same as ftp. Use sftp instead of ftp when logging on to a server that is running the OpenSSH daemon, sshd. The major difference between sftp and ftp is that the former uses encryption to transfer password over network whereas the later does not.
The format to connect to a remote system is:
# sftp [options] [user@]host
Enter help or ? to display a list of sftp commands.
