TFTP(1)			  BSD General Commands Manual		       TFTP(1)

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 con‐
	      nections 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.

     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 file‐
	      name 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 dif‐
     ficult to document here.

     The tftp command appeared in 4.3BSD.
