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:

       ? command-name ...
                Print help information.

       ascii    Shorthand for "mode ascii"

       binary   Shorthand for "mode binary"

       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 betwen 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.

       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
                hosts: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.

       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 hosts: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.

       quit     Exit tftp.  An end of file also exits.

       rexmt retransmission-timeout
                Set the per-packet retransmission timeout, in seconds.

       status   Show current status.

       timeout total-transmission-timeout
                Set the total transmission timeout, in seconds.

       trace    Toggle packet tracing.

       verbose  Toggle verbose mode.

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.

HISTORY

       The tftp command appeared in 4.3BSD.
