NAME | SYNOPSIS | DESCRIPTION | COMMANDS | ATTRIBUTES | BUGS
The tftp interface 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).
Once tftp is running, it issues the prompt tftp> and recognizes the following commands:
Print help information
Shorthand for "mode ascii".
Shorthand for "mode binary".
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. It is not necessary to use the connect command; the remote host can be specified as part of the get or put commands.
Get a file or set of files from the specified sources. The 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 host specified becomes the default for future transfers.
Set the mode for transfers; transfer-mode may be one of ascii or binary. The default is ascii.
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.
Exit tftp. An end of file also exits.
Set the per-packet retransmission timeout, in seconds.
Show current status.
Set the total transmission timeout, in seconds.
Toggle packet tracing.
Toggle verbose mode.

Because there is no user-login or validation within the TFTP protocol, the remote site can have file-access restrictions. The exact methods are specific to each site, and therefore difficult to document here.
