NAME

ftp - ®le transfer program

SYNOPSIS

ftp [-g] [-i] [-n] [-c] [-P] [-v] [-Bsize] [ server-host]

DESCRIPTION

ftp is a user interface to the File Transfer Protocol. ftp copies ®les 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:

-gDisable ®le name ``globbing''; see the glob command, below. By default, when this option is not speci®ed, globbing is enabled.

-iDisable interactive prompting by multiple-®le commands; see the prompt command, below. By default, when this option is not speci®ed, prompting is enabled.

-PDisables Kerberos authentication and authorization. Only applicable in a secure environment based on Kerberos V5. When this option is speci®ed, a password is required and the password is sent across the network in a readable form. By default, if this option is not speci®ed, a password is not required and Kerberos authentication and authorization takes place instead. See sis(5).

-nDisable ``auto-login''; see the open command, below. By default, when this option is not speci®ed, auto-login is enabled.

-cWhen this option is set, the SYST and TYPE calls are not made by the ftp client to the server upon establishing a connection. The -coption takes effect only when auto-login is disabled i.e. when it is invoked along with the -noption. This option does not disable the SYST and TYPE commands, but only refrains from invoking these commands upon establishing a con- nection.

-vEnable verbose output; see the verbose command, below. If this option is not speci®ed, ftp displays verbose output only if the standard input is associated with a terminal.

-BSet the buffer size of the data socket to size blocks of 1024 bytes. The valid range for size is an integer from 1 to 64 (default is 56).

Note: A large buffer size will improve the performance of ftp on fast links (e.g., FDDI), but may cause long connection times on slow links (e.g., X.25).

The name of the server host that ftp communicates with can be speci®ed on the command line. If the server host is speci®ed, ftp immediately opens a connection to the server host; see the open command, below. Otherwise, ftp waits for commands from the user.

File Transfer Protocol speci®es ®le transfer parameters for type, mode, form, and struct. ftp supports the ASCII, binary, and tenex File Transfer Protocol types. ASCII is the default FTP type. (It should be noted though that, whenever ftp establishes a connection between two similar systems, it switches automatically to the more ef®cient binary type.) ftp supports only the default values for the ®le transfer parameters mode which defaults to stream, form which defaults to non-print, and 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 speci®es which shell program to invoke. ftp invokes /usr/bin/sh if SHELL is unde®ned. If command is speci®ed, the shell executes it and returns to ftp. Otherwise, an interactive shell is invoked. When the shell ter- minates, it returns to ftp.

$ macro-name [ args ]

Execute the macro macro-namethat was de®ned with the macdef command. Arguments are passed to the macro unglobbed.

account [ passwd ]

Supply a supplemental password required by a remote system for access to resources once a login has
