tftp [-i] [Host] //全：tftp [-v][-m mode] [host [port]] [-c command]
{get | put} [Source] [Destination]

参数
-i

指定二进制图像传送模式（也称为八进制模式）。在二进制图像模式下，文件以一个字节为单位进行传输。在传送二进制文件时使用该模式。如果省略了 -i，文件将以 ASCII 模式传送。这是默认的传送模式。该模式将行尾 (EOL) 字符转换为指定计算机的适当格式。传送文本文件时使用该模式。如果文件传送成功，将显示数据传输率。

Host

指定本地或远程计算机。

put

将本地计算机上的 Destination文件 传送到远程计算机上的 Source文件中。因为TFTP不支持用户身份验证，所以用户必须登录到远程计算机，同时文件在远程计算机上必须可写。

get

将远程计算机上的 Destination 文件传送到本地计算机上的 Source 文件中。

Source

指定要传送的文件。

Destination

指定将文件送达的目标文件。如果省略了 Destination，将假定它与 Source 具有相同名称。

NAME

tftp - Trivial File Transfer Protocol client

SYNOPSIS

tftp [ options... ] [host [port]] [-c command]

DESCRIPTION

tftp is a client for the Trivial file Transfer Protocol, which can be used to transfer files to and from remote machines, including some very minimalistic, usually embedded, systems. 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.)

OPTIONS

Tag	Description
-4	Connect with IPv4 only, even if IPv6 support was compiled in.
-6	Connect with IPv6 only, if compiled in.
-c command
	Execute command as if it had been entered on the tftp prompt. Must be specified last on the command line.
-l	Default to literal mode. Used to avoid special processing of ’:’ in a file name.
-m mode	Set the default transfer mode to mode. This is usually used with -c.
-R port:port
	Force the originating port number to be in the specified range of port numbers.
-v	Default to verbose mode.
-V	Print the version number and configuration to standard output, then exit gracefully.

COMMANDS

Once tftp is running, it issues the prompt tftp> and recognizes the following commands:

Tag	Description
? command-name... help command-name...
	Print help information
ascii	Shorthand for mode ascii.
binary	Shorthand for mode binary.
connect host [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 connectcommand 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 file

get remotefile localfile

get file1 file2 file3...
	Get a file or set of files from the specified sources. A remote filename can be in one of two forms: a plain 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. Enable literal mode to prevent special treatment of the ’:’ character (e.g. C:dirfile).
literal
	Toggle literal mode. When set, this mode prevents special treatment of ’:’ in filenames.
mode transfer-mode
	Specify the mode for transfers; transfer-mode may be one of ascii (or netascii) orbinary (or octet.) The default is ascii.
put file

put localfile remotefile

put file1 file2 file3... 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 system or another system using / as directory separator. Enable literal mode to prevent special treatment of the ’:’ character (e.g. C:dirfile).
quit	Exit tftp. End-of-file will also exit.
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 (a debugging feature.)
verbose
	Toggle verbose mode.

NOTES

The TFTP protocol provides no provisions for authentication or security. Therefore, the remote server will probably implement some kinds of access restriction or firewalling. These access restrictions are likely to be site- and server-specific.
