NAME
tftp - trivial file transfer program
SYNOPSIS
tftp [ host ]
DESCRIPTION
Tftp is the user interface to the Internet TFTP (Trivial
File Transfer Protocol), which allows users to transfer
files to and from a remote machine. The remote host may be
specified on the command line, in which case tftp uses host
as the default host for future transfers (see the connect
command below).
COMMANDS
Once tftp is running, it issues the prompt tftp> and
recognizes the following commands:
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.
mode transfer-mode
Set the mode for transfers; transfer-mode may be one of
ascii or binary. The default is ascii.
put file
put localfile remotefile
put file1 file2 ... fileN remote-directory
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 machine.
get filename
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. An end of file also exits.
verbose
Toggle verbose mode.
trace
Toggle packet tracing.
status
Show current status.
rexmt retransmission-timeout
Set the per-packet retransmission timeout, in seconds.
timeout total-transmission-timeout
Set the total transmission timeout, in seconds.
ascii
Shorthand for "mode ascii"
binary
Shorthand for "mode binary"
? [ command-name ... ]
Print help information.
BUGS
Because there is no user-login or validation within the TFTP
protocol, the remote site will probably have some sort of
file-access restrictions in place. The exact methods are
specific to each site and therefore difficult to document
here.
