ftp is the user interface to the Internet
standard File Transfer Protocol. The program allows a user to transfer files
to and from a remote network site.
The last five arguments will fetch a file using the FTP or HTTP protocols, or by direct copying, into the current directory. This is ideal for scripts. Refer to AUTO-FETCHING FILES below for more information.
Options may be specified at the command line, or to the command interpreter.
-4ftp to only use IPv4 addresses.-6ftp to only use IPv6 addresses.-Aftp will try to
use passive mode ftp and fall back to active mode if passive is not
supported by the server. This option causes ftp to
always use an active connection. It is only useful for connecting to very
old servers that do not implement passive mode properly.-aftp to bypass normal login procedure, and
use an anonymous login instead.-d-e-f-g-i-N

“auto-login” upon initial connection for non auto-fetch
transfers. If auto-login is enabled, ftp will
check the .netrc (see below) file in the user's
home directory for an entry describing an account on the remote machine.
If no entry exists, ftp will prompt for the remote
machine login name (default is the user identity on the local machine),
and, if necessary, prompt for a password and an account with which to
login. To override the auto-login for auto-fetch transfers, specify the
username (and optionally, password) as appropriate.-o

communicate may be specified on the command line. If this is done,
ftp will immediately attempt to establish a

ftp will enter its command interpreter and await

csh(1). For
mdelete, mget, and
mreget, each remote file name is expanded
separately on the remote machine and the lists are not merged. Expansion
of a directory name is likely to be different from expansion of the name
of an ordinary file: the exact result depends on the foreign operating
system and ftp server, and can be previewed by doing
‘mls remote-files -’ Note:
mget, mput and
mreget are not meant to transfer entire directory

The macro processor interprets ‘$’ and ‘\’ as special characters. A ‘$’ followed by a number (or numbers) is replaced by the corresponding argument on the macro invocation command line. A ‘$’ followed by an ‘i’ signals the macro processor that the executing macro is to be looped. On the first pass “$i” is replaced by the first argument on the macro invocation command line, on the second pass it is replaced by the second argument, and so on. A ‘\’ followed by any character is replaced by that character. Use the ‘\’ to prevent special treatment of the ‘$’.

commands and put commands issued without a
specified remote target filename. If arguments are specified, local
filenames are mapped during mget commands and
get commands issued without a specified local
target filename. This command is useful when connecting to a
non-UNIX remote computer
with different file naming conventions or practices. The mapping follows
the pattern set by inpattern and
outpattern. [Inpattern] is a
template for incoming filenames (which may have already been processed
according to the ntrans and
case settings). Variable templating is
accomplished by including the sequences “$1”,
“$2”, ... “$9” in
inpattern. Use ‘\’ to prevent this
special treatment of the ‘$’ character. All other characters
are treated literally, and are used to determine the
nmap [inpattern] variable
values. For example, given inpattern $1.$2 and the
remote file name "mydata.data", $1 would have the value
"mydata", and $2 would have the value "data". The
outpattern determines the resulting mapped filename.
The sequences “$1”, “$2”, ...
“$9” are replaced by any value resulting from the
inpattern template. The sequence “$0”
is replaced by the original filename. Additionally, the sequence
“[seq1, seq2]”
is replaced by [seq1] if seq1
is not a null string; otherwise it is replaced by
seq2. For example, the command
nmap $1.$2.$3 [$1,$2].[$2,file]
would yield the output filename "myfile.data" for input filenames "myfile.data" and "myfile.data.old", "myfile.file" for the input filename "myfile", and "myfile.myfile" for the input filename ".myfile". Spaces may be included in outpattern, as in the example:
nmap $1 sed s/ *$// >
$1ntrans
[inchars [outchars]]mput commands and
put commands issued without a specified remote
target filename. If arguments are specified, characters in local filenames
are translated during mget commands and
get commands issued without a specified local
target filename. This command is useful when connecting to a
non-UNIX remote computer
with different file naming conventions or practices. Characters in a
filename matching a character in inchars are
replaced with the corresponding character in
outchars. If the character's position in
inchars is longer than the length of
outchars, the character is deleted from the file
name.open

FTPMODE is set to ‘auto’. If passive
mode is turned on (default), ftp will send a
PASV command for all data connections instead of a
PORT command. The PASV
command requests that the remote server open a port for the data
connection and return the address of that port. The remote server listens
on that port and the client connects to it. When using the more
traditional PORT command, the client listens on a
port and sends that address to the remote server, who connects back to it.
Passive mode is useful when using ftp through a
gateway router or host that controls the directionality of traffic. (Note

PORT commands is disabled, no attempt will be made
to use PORT commands for each data transfer. This
is useful for certain FTP implementations which do ignore
PORT commands but, incorrectly, indicate they've
been accepted.set

Commands which toggle settings can take an explicit

Commands which take a byte count as an argument (e.g.,
hash, rate, and
xferbuf) support an optional suffix on the argument
which changes the interpretation of the argument. Supported suffixes
are:
If ftp receives a
SIGINFO (see the “status” argument of
stty(1)) or
SIGQUIT signal whilst a transfer is in progress, the
current transfer rate statistics will be written to the standard error
output, in the same format as the standard completion message.
In addition to standard commands, this version of
ftp supports an auto-fetch feature. To enable
auto-fetch, simply pass the list of hostnames/files on the command line.
The following formats are valid syntax for an auto-fetch element:
@]host:[path][/]If path contains a glob character and
globbing is enabled, (see glob), then the
equivalent of ‘mget path’ is
performed.
If the directory component of path
contains no globbing characters, it is stored locally with the name
basename (see
basename(1)) of
path, in the current directory. Otherwise, the
full remote name is used as the local name, relative to the local root
directory.
ftp://[user[:password]@]host[:port]/path[/][;type=X]set
ftp_proxy isn't defined. Otherwise, transfer the URL using HTTP via
the proxy defined in set ftp_proxy. If
set ftp_proxy isn't defined and
user is given, login as user.
In this case, use password if supplied, otherwise
prompt the user for one.
If a suffix of ‘;type=A’ or ‘;type=I’ is supplied, then the transfer type will take place as ascii or binary (respectively). The default transfer type is binary.
In order to be compliant with RFC
3986, ftp interprets the
path part of an “ftp://” auto-fetch
URL as follows:
/’ immediately after the
host[:port]
is interpreted as a separator before the path,
and not as part of the path itself./’-separated list of name
components. For all but the last such component,
ftp performs the equivalent of a
cd command. For the last path component,
ftp performs the equivalent of a
get command.//’ within the
path, or from an extra
‘/’ at the beginning of the
path, will cause the equivalent of a
cd command without a directory name. This is
unlikely to be useful.%XX’
codes (per RFC 3986) within the path
components are decoded, with XX representing a
character code in hexadecimal. This decoding takes place after the
path has been split into components, but before
each component is used in the equivalent of a
cd or get command.
Some often-used codes are ‘%2F’
(which represents ‘/’) and
‘%7E’ (which represents
‘~’).The above interpretation has the following consequences:
cd and get
commands can be controlled by careful choice of where to use
‘/’ and where to use ‘%2F’ (or
‘%2f’). For example, the following URLs correspond to
the equivalents of the indicated commands:
cd command.http://[user[:password]@]host[:port]/pathset
http_proxy is defined, it is used as a URL to an HTTP proxy server.
If HTTP authorization is required to retrieve path,
and ‘user’ (and optionally ‘password’) is in
the URL, use them for the first attempt to authenticate.https://[user[:password]@]host[:port]/pathset
https_proxy is defined, it is used as a URL to an HTTPS proxy
server. If HTTPS authorization is required to retrieve
path, and ‘user’ (and optionally
‘password’) is in the URL, use them for the first attempt to
authenticate. There is currently no certificate validation and
verification.file:///pathabout:topicabout:ftpftp.about:versionftp. Useful to provide when
reporting problems.Unless noted otherwise above, and -o
output is not given, the file is stored in the current
directory as the
basename(1) of
path. Note that if a HTTP redirect is received, the
fetch is retried using the new target URL supplied by the server, with a
corresponding new path. Using an explicit
-o output is recommended, to
avoid writing to unexpected file names.
If a classic format or an FTP URL format has a trailing
‘/’ or an empty path component, then
ftp will connect to the site and
cd to the directory given as the path, and leave the
user in interactive mode ready for further input. This will not work if
set ftp_proxy is being used.
Direct HTTP transfers use HTTP 1.1. Proxied FTP and HTTP transfers use HTTP 1.0.
If -R is given, all auto-fetches that
don't go via the FTP or HTTP proxies will be restarted. For FTP, this is
implemented by using reget instead of
get. For HTTP, this is implemented by using the
‘Range: bytes=’ HTTP/1.1 directive.
If WWW or proxy WWW authentication is required, you will be prompted to enter a username and password to authenticate with.
When specifying IPv6 numeric addresses in a URL, you need to surround the address in square brackets. E.g.: “ftp://[::1]:21/”. This is because colons are used in IPv6 numeric address as well as being the separator for the port number.
To abort a file transfer, use the terminal interrupt key (usually
Ctrl-C). Sending transfers will be immediately halted. Receiving transfers
will be halted by sending an FTP protocol ABOR
command to the remote server, and discarding any further data received. The
speed at which this is accomplished depends upon the remote server's support
for ABOR processing. If the remote server does not
support the ABOR command, the prompt will not appear
until the remote server has completed sending the requested file.
If the terminal interrupt key sequence is used whilst
ftp is awaiting a reply from the remote server for
the ABOR processing, then the connection will be closed. This is different
from the traditional behaviour (which ignores the terminal interrupt during
this phase), but is considered more useful.
Files specified as arguments to ftp
commands are processed according to the following rules.
-’ is specified,
the stdin (for reading) or
stdout (for writing) is used.ftp then forks a shell, using
popen(3) with the
argument supplied, and reads (writes) from the stdout (stdin). If the
shell command includes spaces, the argument must be quoted; e.g.
“"| ls -lt"”. A
particularly useful example of this mechanism is:
“dir "" |more”.glob command. If the ftp
command expects a single local file (e.g. put),
only the first filename generated by the "globbing" operation is
used.mget commands and get
commands with unspecified local file names, the local filename is the
remote filename, which may be altered by a case,
ntrans, or nmap setting.
The resulting filename may then be altered if
runique is on.mput commands and put
commands with unspecified remote file names, the remote filename is the
local filename, which may be altered by a ntrans
or nmap setting. The resulting filename may then
be altered by the remote server if sunique is
on.The FTP specification specifies many parameters which may affect a
file transfer. The type may be one of
“ascii”, “image” (binary),
“ebcdic”, and “local byte size” (for PDP-10's
and PDP-20's mostly). ftp supports the ascii and
image types of file transfer, plus local byte size 8 for
tenex mode transfers.
ftp supports only the default values for
the remaining file transfer parameters: mode,
form, and struct.
The .netrc file contains login and
initialization information used by the auto-login process. It resides in the
user's home directory, unless overridden with the -N
netrc option, or specified in the
NETRC environment variable. The following tokens are
recognized; they may be separated by spaces, tabs, or new-lines:
machine
namemachine token that matches the remote machine
specified on the ftp command line or as an
open command argument. Once a match is made, the
subsequent .netrc tokens are processed, stopping
when the end of file is reached or another machine
or a default token is encountered.defaultmachine
name except that default
matches any name. There can be only one default
token, and it must be after all machine tokens.
This is normally used as:

machines not specified in .netrc. This can be
overridden by using the -n flag to disable
auto-login.

macdef command functions. A macro is defined with
the specified name; its contents begin with the next
.netrc line and continue until a blank line
(consecutive new-line characters) is encountered. Like the other tokens in
the .netrc file, a macdef
is applicable only to the machine definition
preceding it. A macdef entry cannot be used by
multiple machine definitions; rather, it must be
defined following each machine it is intended to
be used with. If a macro named init is defined, it
is automatically executed as the last step in the auto-login process. For
example,
default macdef init epsv4 off
followed by a blank line.
ftp supports interactive command line
editing, via the
editline(3) library. It
is enabled with the edit command, and is enabled by
default if input is from a tty. Previous lines can be recalled and edited
with the arrow keys, and other GNU Emacs-style editing keys may be used as
well.
The editline(3) library is configured with a .editrc file - refer to editrc(5) for more information.
An extra key binding is available to ftp
to provide context sensitive command and filename completion (including
remote file completion). To use this, bind a key to the
editline(3) command
ftp-complete. By default, this is bound to the TAB
key.
By default, ftp displays a command line
prompt of “ftp> ” to the user. This can be changed with the
set prompt command.
A prompt can be displayed on the right side of the screen (after
the command input) with the set rprompt command.
The following formatting sequences are replaced by the given information:

3986The ftp command appeared in
4.2BSD.
Various features such as command line editing, context sensitive
command and file completion, dynamic progress bar, automatic fetching of
files and URLs, modification time preservation, transfer rate throttling,
configurable command line prompt, and other enhancements over the standard
BSD ftp were implemented in
NetBSD 1.3 and later releases by
Luke Mewburn ⟨lukem@NetBSD.org⟩.
IPv6 support was added by the WIDE/KAME project (but may not be present in all non-NetBSD versions of this program, depending if the operating system supports IPv6 in a similar manner to KAME).
Correct execution of many commands depends upon proper behavior by the remote server.
An error in the treatment of carriage returns in the 4.2BSD ascii-mode transfer code has been corrected. This correction may result in incorrect transfers of binary files to and from 4.2BSD servers using the ascii type. Avoid this problem by using the binary image type.
ftp assumes that all IPv4 mapped addresses
(IPv6 addresses with a form like ::ffff:10.1.1.1)
indicate IPv4 destinations which can be handled by
AF_INET sockets. However, in certain IPv6 network
configurations, this assumption is not true. In such an environment, IPv4
mapped addresses must be passed to AF_INET6 sockets
directly. For example, if your site uses a SIIT translator for IPv6-to-IPv4
translation, ftp is unable to support your
configuration.
