NAME

ftp – file transfer protocol

SYNOPSIS

ftp [-d] [-g] [-i] [-n] [-t] [-v] [-wwsize] [host [port]]

DESCRIPTION

Ftp is the user interface to the ARPANET standard File Transfer Protocol (FTP). This protocol allows a user to transfer files to and from a remote network site. The ftp client includes a command interpreter which interactively executes file transfer commands. The command interpreter prompt is ftp>. Ftp can also be run from a shell script, taking its input from a file.

Several options may be specified on the ftp command line. Most options correspond to an ftp command and are discussed in more detail in the description of the referenced command.

–d enable debugging (debug).

–g disable file name globbing (glob).

–i turn off interactive prompting during multiple file transfers (prompt).

–n disable autologin upon initial connection.

–t enable packet tracing (trace).

–v enable verbose mode (verbose).

–wwsize

set the TCP window size.

If no host is specified on the command line, ftp will enter its command interpreter and await further instructions from the user. If a host is specified, ftp will immediately attempt to establish a connection to an FTP server on that host. Host can be either the host name or its Internet address. If the host is followed by a port, ftp will attempt to contact an FTP server at that port. Port can be either the port number or the name of the service associated with that port (see services(4)).

If autologin is enabled (default), ftp will check the .netrc(4) file in the user's home directory for an entry describing an account on the remote host. If such an entry exists, ftp will automatically log in to that account. If no entry is found, ftp will use the local user name as the login on the remote host and prompt for a password [and account] to complete the login. If autologin is disabled, ftp will establish the initial connection to the remote host and return to the command interpreter. The user command must then be used to log in to that host.

File names specified as arguments to ftp commands are processed according to the following rules.

1)If the file name is -, stdin (for reading) or stdout (for writing) will be used.
