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.  See tftpd(1M) for details about customizing
     file-access restrictions on IRIX.
