Description:

sftp is an ftp replacement that runs over an ssh tunnel. Two programs
are included - sftp and sftpserv. When sftp is run and a host is
connected to (either by running 'sftp remotehost' or 'open remotehost'
from the sftp prompt), an ssh connection is initiated to the remote
host, and sftpserv is run. From within sftp, all of the normal FTP
commands are present: open, close, get, put, pwd, cd, ls, lcd, quit,
etc. There's also exec, which runs a program on the remote end.
