Class Summary

FtpCmdAbor	ABORT (ABOR) This command tells the server to abort the previous FTP service command and any associated transfer of data.
FtpCmdAllo	ALLOCATE (ALLO) This command may be required by some servers to reserve sufficient storage to accommodate the new file to be transferred.
FtpCmdAppe	APPEND (with create) (APPE) This command causes the server-DTP to accept the data transferred via the data connection and to store the data in a file at the server site.
FtpCmdAuth	AUTHENTICATION/SECURITY MECHANISM (AUTH) The argument field is a Telnet string identifying a supported mechanism.
FtpCmdCdup	CHANGE TO PARENT DIRECTORY (CDUP) This command is a special case of CWD, and is included to simplify the implementation of programs for transferring directory trees between operating systems having different syntaxes for naming the parent directory.
FtpCmdClnt
FtpCmdCwd	CHANGE WORKING DIRECTORY (CWD) This command allows the user to work with a different directory or dataset for file storage or retrieval without altering his login or accounting information.
FtpCmdDele	DELETE (DELE) This command causes the file specified in the pathname to be deleted at the server site.
FtpCmdEprt	The EPRT Command (EPRT) The EPRT command allows for the specification of an extended address for the data connection.
FtpCmdEpsv	The EPSV Command (EPSV) The EPSV command requests that a server listen on a data port and wait for a connection.
FtpCmdFeat	FEAT Command It is not to be expected that all servers will necessarily support all of the new commands defined in all future amendments to the FTP protocol.
FtpCmdHelp	HELP (HELP) This command shall cause the server to send helpful information regarding its implementation status over the control connection to the user.
FtpCmdList	LIST (LIST) This command causes a list to be sent from the server to the passive DTP.
FtpCmdMdtm	MDTM Modifies the timestamp of a file or path.
FtpCmdMkd	MAKE DIRECTORY (MKD) This command causes the directory specified in the pathname to be created as a directory (if the pathname is absolute) or as a subdirectory of the current working directory (if the pathname is relative).
FtpCmdMode	TRANSFER MODE (MODE) The argument is a single Telnet character code specifying the data transfer modes described in the Section on Transmission Modes.
FtpCmdNlst	NAME LIST (NLST) This command causes a directory listing to be sent from server to user site.
FtpCmdNoop	NOOP (NOOP) This command does not affect any parameters or previously entered commands.
FtpCmdNotImpl	This class represents commands not implemented yet.
FtpCmdOpts	OPTS Command The OPTS (options) command allows a user-PI to specify the desired behavior of a server-FTP process when another FTP command (the target command) is later issued.
FtpCmdPass	PASSWORD (PASS) The argument field is a Telnet string specifying the user's password.
FtpCmdPasv	PASSIVE (PASV) This command requests the server-DTP to "listen" on a data port (which is not its default data port) and to wait for a connection rather than initiate one upon receipt of a transfer command.
FtpCmdPbsz	PROTECTION BUFFER SIZE (PBSZ) The argument is a decimal integer representing the maximum size, in bytes, of the encoded data blocks to be sent or received during file transfer.
FtpCmdPort	DATA PORT (PORT) The argument is a HOST-PORT specification for the data port to be used in data connection.
FtpCmdProt	DATA CHANNEL PROTECTION LEVEL (PROT) The argument is a single Telnet character code specifying the data channel protection level.
FtpCmdPwd	PRINT WORKING DIRECTORY (PWD) This command causes the name of the current working directory to be returned in the reply..
FtpCmdQuit	LOGOUT (QUIT) This command terminates a USER and if file transfer is not in progress, the server closes the control connection.
FtpCmdRest	RESTART (REST) The argument field represents the server marker at which file transfer is to be restarted.
FtpCmdRetr	RETRIEVE (RETR) This command causes the server-DTP to transfer a copy of the file, specified in the pathname, to the server- or user-DTP at the other end of the data connection.
FtpCmdRmd	REMOVE DIRECTORY (RMD) This command causes the directory specified in the pathname to be removed as a directory (if the pathname is absolute) or as a subdirectory of the current working directory (if the pathname is relative).
FtpCmdRnfr	RENAME FROM (RNFR) This command specifies the old pathname of the file which is to be renamed.
FtpCmdRnto	RENAME TO (RNTO) This command specifies the new pathname of the file specified in the immediately preceding "rename from" command.
FtpCmdSize	SIZE Returns the size of the passed path in bytes.
FtpCmdStat	STATUS (STAT) This command shall cause a status response to be sent over the control connection in the form of a reply.
FtpCmdStor	STORE (STOR) This command causes the server-DTP to accept the data transferred via the data connection and to store the data as a file at the server site.
FtpCmdStou	STORE UNIQUE (STOU) This command behaves like STOR except that the resultant file is to be created in the current directory under a name unique to that directory.
FtpCmdStru	FILE STRUCTURE (STRU) The argument is a single Telnet character code specifying file structure described in the Section on Data Representation and Storage.
FtpCmdSyst	SYSTEM (SYST) This command is used to find out the type of operating system at the server.
FtpCmdType	REPRESENTATION TYPE (TYPE) The argument specifies the representation type as described in the Section on Data Representation and Storage.
FtpCmdUser	USER NAME (USER) The argument field is a Telnet string identifying the user.
