TFTP(1) OpenBSD Reference Manual TFTP(1)
tftp - trivial file transfer program
tftp is the user interface to the Internet TFTP (Trivial File Transfer
Protocol), which allows users to transfer files to and from a remote ma-
chine. 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
? 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 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
get remotename localname
get file [...]
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.
Set the mode for transfers; transfer-mode may be one of ascii or
binary. The default is ascii.
put localfile remotefile
put file1 file2 ... fileN remote-directory
Put a file or set of files to the specified remote file or di-
rectory. 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.
Set the per-packet retransmission timeout, in seconds.
status Show current status.
Set the total transmission timeout, in seconds.
trace Toggle packet tracing.
verbose Toggle verbose mode.
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.
