tftp - trivial file transfer program
tftp is the user interface to the Internet TFTP (Trivial File Transfer
Protocol), that allows users to transfer files to and from a remote
machine. The remote host can be specified on the command line, in
which case tftp uses host as the default host for future transfers
(see the connect command below).
Once tftp is running, it issues the prompt tftp>>>> and recognizes the
connect host-name [port]
Set the host (and optionally port) for transfers.
Note that the TFTP protocol, unlike the FTP protocol,
does not maintain connections between transfers;
thus, the connect command does not actually create a
connection, but merely remembers what host is to be
used for transfers. You do not have to use the
connect command; the remote host can be specified as
part of the get or put commands.
Set the mode for transfers; transfer-mode can be one
of ascii or binary (default is ascii).
put localfile remotefile
put file1 file2 ... fileN remotedirectory
Put a file or set of files to the specified remote
file or directory. The destination can be in one of
two forms: a filename on the remote host if the host
has already been specified, or a string of the form
host:filename to specify both a host and filename at
the same time. If the latter form is used, the
hostname specified becomes the default for future
transfers. If the remote-directory form is used, the
remote host is assumed to be a UNIX-like machine.
get remotename localname
get file1 file2 ... fileN
Get a file or set of files from the specified
sources. source can be in one of two forms: a
filename on the remote host if the host has already
been specified, or a string of the form host:filename

to specify both a host and filename at the same time.
If the latter form is used, the last hostname
specified becomes the default for future transfers.
quit Exit tftp. Typing the end-of-file character also
causes an exit.
verbose Toggle verbose mode.
trace Toggle packet tracing.
status Show current status.
Set the per-packet retransmission timeout, in
Set the total transmission timeout, in seconds.
ascii Shorthand for "mode ascii"
binary Shorthand for "mode binary"
Print help information.
Since there is no user-login or validation within the TFTP protocol,
the remote site probably has some sort of file-access restrictions in
place. The exact methods are specific to each site and are therefore
difficult to document here.
tftp was developed by the University of California, Berkeley.
