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 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.
