NAME
tftp - trivial file transfer program
SYNOPSIS
tftp [host]
DESCRIPTION
The tftp command is the user interface to the Internet TFTP
(Trivial File Transfer Protocol), which allows users to
transfer files to and from a remote machine.
USAGE
The remote host may be specified on the command line, in which
case tftp uses host as the default host for future transfer
(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. 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 filename
put localfile remotefile
put filename1 filename2 . . . filenameN remote-directory
Transfer a file, or a 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 specified host becomes
the default for future transfers. If the remote-

directory form is used, the remote host is assumed to be
running the UNIX system.
get filename
get remotename localname
get filename1 filename2 filename3 . . . filenameN
Get a file or set of files (three or more) from the
specified remote 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 host specified
becomes the default for future transfers.
quit Exit tftp. An EOF 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.
Warnings
Because there is no user-login or validation within the TFTP
protocol, many remote sites restrict file access in various
ways. Approved methods for file access are specific to each
site, and therefore cannot be documented here.

When using the get command to transfer multiple files from a
remote host, three or more files must be specified. The
command returns an error message if only two files are
specified.
