以下是可以被发送到FTP服务器的FTP命令行表，包含由IETF在RFC 959中标准化的所有命令。需要注意的是，大多数命令行FTP客户端都给用户提供了额外的命令集。例如，GET是一个常见的用来下载文档的用户命令，用来替代原始的RETR命令。

Below is a list of FTP commands that may be sent to an FTP server, including all commands that are standardized in RFC 959 by the IETF. All commands below are RFC 959 based unless stated otherwise. Note that most command-line FTP clients present their own set of commands to users. For example, GET is the common user command to download a file instead of the raw command RETR.
