Introduction
The following information is provided as a reference for the File Transfer Protocol (FTP) commands. This document describes a typical process for an interactive and automated, batch FTP session running on a PC with Windows/XP and connecting to a UNIX system. This process may vary slightly depending on the hardware and software configurations of the local and remote systems.
An Interactive FTP Session
(Next) (Previous) (Table-of-Contents)
To start an FTP interactive session type “ftp” from a DOS Command window.
C:\> ftp
The DOS prompt should be replaced with the FTP prompt. The FTP program is now running on the local system. A connection (or session) to a remote system has not been established.
The help command or ? (question mark) may be executed without being attached to a remote system and will do a print (usually to the screen) of the FTP commands. The following is an example of an FTP Command to display the FTP Help information.
ftp help
The following is a typical result of the help command running on a PC with Windows.
Commands may be abbreviated. Commands are: ! delete literal prompt send ? debug ls put status append dir mdelete pwd trace ascii disconnect mdir quit type bell get mget quote user binary glob mkdir recv verbose bye hash mls remotehelp cd help mput rename close lcd open rmdir ftp
The following FTP Command will perform the FTP OPEN (make the connection) and display the following messages.
ftp open domain.name Connected to domain.name 220 antigonous FTP server ready. User (domain.name:(none)): User-Name 331 Password required for user-name Password: password 230 User user-name logged in. ftp
The following FTP Command will change the directory on the remote system and display the following message.
ftp> cd /web 250 CWD command successful. ftp
The following FTP Command will find out the pathname of the current directory on the remote system and display the information.
ftp> pwd 257 "/web" is the current directory. ftp
The following FTP Command will set the file transfer mode to ASCII (this is the default for most FTP programs) and display the information.
ftp> ascii 200 Type set to A. ftp
The following FTP Command will copy a file(using ASCII mode) from the local system to the remote system and display the information.
ftp> put d:\simoweb1\filename.txt 200 PORT command successful. Opening ASCII mode data connection for filename.txt 226 Transfer complete ftp
The following FTP Command will set the file transfer mode to BINARY (the binary mode transfers all eight bits per byte and must be used to transfer non-ASCII files). ) and display the information.
ftp> binary 200 Type set to I. ftp
The following FTP Command will copy a file (using BINARY mode) from the local system to the remote system and display the information.
ftp> put d:\simoweb1\filename.zip 200 PORT command successful. Opening BINARY mode data connection for filename.zip 226 Transfer complete ftp
The following FTP Command will exit the FTP environment (same as “bye”) and display the information.
ftp> quit 221 Goodbye.
When the preceding FTP Command is finished the DOS prompt will be displayed.
C:\>
The preceding is a typical process for an interactive FTP session running on a PC with Windows/XP or Windows/7 and connecting to a UNIX system. This process may vary slightly depending on the hardware and software configurations of the local and remote systems.
An Automated, Batch FTP Session
(Next) (Previous) (Table-of-Contents)
The following batch file (UPWIP001.BAT) will start an FTP session and pass the name of a text file (UPWIP001.TXT) to the FTP program. This text file will be processed by the FTP program and each of the statements in the text file will be processed in the sequence they appear.

The following is a listing of the contents of the text file (UPWIP001.TXT).

FTP Extended Command, LOCSITE, LITERAL and SITE
This SITE (via the literal or quote command) statement is used at the client system and the LOCSITE command is used at the host system. Both statements are used to transfer a function to the host site. The following is a summary of the commonly used SITE/LOCSITE Commands.

||||||||||||||||||||
| Parameters used with the LOCSITE Extended FTP Commands |
The following is an example of the LITERAL command and a GET command. The commands are executed at the client and will cause the RDW (Record Descriptor Word) to be included at the beginning of each record of a file with variable length records.
LITERAL SITE RDW GET host-file-name client-file-name
The following is an example of the LOCSITE command and a PUT command. The commands are executed at the host and will cause the RDW (Record Descriptor Word) to be included at the beginning of each record of a file with variable length records.
LOCSITE RDW PUT host-file-name client-file-name
