NAME

ftp - ﬁle transfer program

SYNOPSIS

ftp [-g][-i][

-n][-c][-v][-p][-P][-l][

-B size][-z options ...] [ server-host ]

DESCRIPTION

ftp is a user interface to the File Transfer Protocol.

ftp copies ﬁles over a network connection

between the local "client" host and a remote "server" host.

ftp

runs on the client host.

Options

The

ftp command supports the following options:

-g Disable ﬁle name "globbing"; see the

glob command, below. By default, when this option is

not speciﬁed, globbing is enabled.

-i Disable interactive prompting by multiple-ﬁle commands; see the

prompt command, below.

By default, when this option is not speciﬁed, prompting is enabled.

-n Disable "auto-login"; see the

open command, below. By default, when this option is not

speciﬁed, auto-login is enabled.

-c When this option is set, the SYST and TYPE calls are not made by the

ftp client to the server

upon establishing a connection. The

-c option takes effect only when auto-login is disabled,

on other words, when it is invoked along with the -n option. This option does not disable the

SYST and TYPE commands, but only refrains from invoking these commands upon establish-

ing a connection.

-v Enable verbose output; see the verbose command, below. If this option is not speciﬁed,

ftp displays verbose output only if the standard input is associated with a terminal.

-p Enable passive mode of operation. Also, refer to the passive command in the COMMANDS

section below. When this option is not speciﬁed, by default the passive mode is disabled.

-P Disables Kerberos authentication and authorization. Only applicable in a secure environment

based on Kerberos V5. When this option is speciﬁed, a password is required and the password

is sent across the network in a readable form. By default, if this option is not speciﬁed, a pass-

word is not required and Kerberos authentication and authorization takes place instead. See

sis(5).

-l In the IPv6 environment, enable the use of LPRT and LPSV commands for data connection. In

this environment, by default ftp uses EPRT and EPSV. In the IPv4 environment PORT and

PASV commands are used.

-B Set the buffer size of the data socket to size blocks of 1024 bytes. The valid range for size is an

integer from 1 to 2097151 (default is 56).

Note : A large buffer size will improve the performance of

ftp on fast links, but may cause

long connection times on slow links (e.g., X.25).

Note : If the buffer size needs to be set to any value other than multiples of 1024 bytes, use

immediately after size without any space. The size value will be taken in terms of bytes. For

example, to set the buffer size to a value equal to "1500", use -B 1500B.

-z Used for TLS/SSL related parameters for the client. More than one -z option can be speciﬁed

on the command line. The different -z options are as follows:

-z CAfile=file

Speciﬁes the ﬁle name for the CA certiﬁcate.

-z CApath=PATH

Speciﬁes the pathname for the CA certiﬁcate.

-z CRLfile=file

Speciﬁes the CRL ﬁle location for the ftp client.

-z CRLpath=PATH

Speciﬁes the pathname of the CRL ﬁle.

-z cert=file

Speciﬁes the location of the clients certiﬁcate ﬁle.

For DSA-formatted files. -z key=file Specifies the location of the clients key file. You can include a RSA or DSA sub-option for the key location, such as: -z rsakey=file -z dsakey=file For RSA-formatted files. For DSA-formatted files. -z cipher=cipher_suites Specifies the list of TLS cipher suites.

ftp(1) ftp(1) struct which defaults to file. COMMANDS ftp supports the following commands. Command arguments with embedded spaces must be enclosed in quotes (for example, "argument with embedded spaces"). ![ command [ args ] ] Invoke a shell on the local host. The SHELL environment variable specifies which shell proftp invokes /usr/bin/sh if SHELL is undefined. If command is gram to invoke. specified, the shell executes it and returns to ftp. Otherwise, an interactive shell is invoked.
PAGE 4
ftp(1) ftp(1) environment PORT/PASV commands are used. form format Set the file transfer form to format . The only supported format is non-print get remote-file [ local-file ] Copy remote-file to local-file . If local-file is unspecified, ftp uses the specified remote-file name as the local-file name, subject to alteration by the current case , ntrans , and nmap settings. glob Toggle file name globbing. When file name globbing is enabled, ftp expands csh (1) metacharacters in file and directory names.
PAGE 5
ftp(1) ftp(1) mode [ mode-name ] Set the FTP file transfer mode to mode-name . The only supported mode is stream. modtime remote-file Show the last modification time of remote-file . mput local-files Copy local-files from the local system to the remote system. The remote files have the same name as the local files processed according to ntrans and nmap settings. If globbing is enabled, globbing characters are expanded.
PAGE 6
ftp(1) ftp(1) prompt Toggle interactive prompting. By default, ftp prompts the user for a yes or no response for each output file during multiple-file commands. If interactive prompting is disabled, ftp performs the command for all specified files. proxy ftp-command Execute an ftp command on a secondary control connection. This command allows simultaneous connection to two remote FTP servers for transferring files between the two servers.
PAGE 7
ftp(1) ftp(1) sendport Toggle the use of PORT commands. By default, ftp attempts to use a PORT command when establishing a connection for each data transfer. If the PORT command fails, ftp uses the default data port. When the use of PORT commands is disabled, ftp makes no attempt to use PORT commands for each data transfer. This is useful for certain FTP implementations that ignore PORT commands but (incorrectly) indicate that they’ve been accepted. See ftpd (1M).

ftp(1) ftp(1) • If the file name - is specified, ftp uses the standard input (for reading) or standard output (for writing). • If the first character of the file name is |, ftp interprets the remainder of the argument as a shell command. ftp forks a shell, using popen() (see popen (3S)) with the supplied argument, and reads (writes) from standard output (standard input).
