List of FTP commands

Below is a list of FTP commands that may be sent to an FTP host, including all commands that are standardized in RFC 959 by the IETF. All commands below are RFC 959 based unless stated otherwise. These commands differ in use between clients. For example, GET is used instead of RETR, but most clients parse this into the proper command.
