file transfer program
tftp is the user interface to the Internet
TFTP (Trivial File Transfer Protocol), which allows users to transfer files

tftp uses them as the default for future
transfers (see the

get[host1:]file1 [host2:]file2 ... [hostN:]fileN

Note that files may only be written to if they already exist on the remote host and are publicly writable. See tftpd(8) for further details.
