    * STOR – store a file on the remote host
    * TYPE – set transfer type
    * USER – send username

    Less common commands

    * ACCT* – send account information
    * APPE – append to a remote file
    * CDUP – CWD to the parent of the current directory
    * HELP – return help on using the server
    * MODE – set transfer mode

    * REIN* – reinitialize the connection
    * STAT – return server status
    * STOU – store a file uniquely
    * STRU – set file transfer structure
    * SYST – return system type

    ABOR
    Syntax: ABOR

    Aborts a file transfer currently in progress.

    ACCT*
    Syntax: ACCT account-info

    This command is used to send account information on systems that require it. Typically sent after a PASS command.

    ALLO
    Syntax: ALLO size [R max-record-size]

    Allocates sufficient storage space to receive a file. If the maximum size of a record also needs to be known, that is sent as a second numeric parameter following a space, the capital letter “R”, and another space.

    APPE
    Syntax: APPE remote-filename

    Append data to the end of a file on the remote host. If the file does not already exist, it is created. This command must be preceded by a PORT or PASV command so that the server knows where to receive data from.

    CDUP
    Syntax: CDUP

    Makes the parent of the current directory be the current directory.

    CWD
    Syntax: CWD remote-directory

    Makes the given directory be the current directory on the remote host.

    DELE
    Syntax: DELE remote-filename

    Deletes the given file on the remote host.

    HELP
    Syntax: HELP [command]

    If a command is given, returns help on that command; otherwise, returns general help for the FTP server (usually a list of supported commands).

    LIST
    Syntax: LIST [remote-filespec]

    If remote-filespec refers to a file, sends information about that file. If remote-filespec refers to a directory, sends information about each file in that directory. remote-filespec defaults to the current directory. This command must be preceded by a PORT or PASV command.

    MDTM
    Syntax: MDTM remote-filename

    Returns the last-modified time of the given file on the remote host in the format “YYYYMMDDhhmmss”: YYYY is the four-digit year, MM is the month from 01 to 12, DD is the day of the month from 01 to 31, hh is the hour from 00 to 23, mm is the minute from 00 to 59, and ss is the second from 00 to 59.

    MKD
    Syntax: MKD remote-directory

    Creates the named directory on the remote host.

    MODE
    Syntax: MODE mode-character

    Sets the transfer mode to one of:

    * S – Stream
    * B – Block
    * C – Compressed

    The default mode is Stream.

    NLST
    Syntax: NLST [remote-directory]

    Returns a list of filenames in the given directory (defaulting to the current directory), with no other information. Must be preceded by a PORT or PASV command.

    NOOP
    Syntax: NOOP

    Does nothing except return a response.

    PASS
    Syntax: PASS password

    After sending the USER command, send this command to complete the login process. (Note, however, that an ACCT command may have to be used on some systems.)

    PASV
    Syntax: PASV

    Tells the server to enter “passive mode”. In passive mode, the server will wait for the client to establish a connection with it rather than attempting to connect to a client-specified port. The server will respond with the address of the port it is listening on, with a message like:
    227 Entering Passive Mode (a1,a2,a3,a4,p1,p2)
    where a1.a2.a3.a4 is the IP address and p1*256+p2 is the port number.

    PORT
    Syntax: PORT a1,a2,a3,a4,p1,p2

    Specifies the host and port to which the server should connect for the next file transfer. This is interpreted as IP address a1.a2.a3.a4, port p1*256+p2.

    PWD
    Syntax: PWD

    Returns the name of the current directory on the remote host.

    QUIT
    Syntax: QUIT

    Terminates the command connection.

    REIN*
    Syntax: REIN

    Reinitializes the command connection – cancels the current user/password/account information. Should be followed by a USER command for another login.

    REST
    Syntax: REST position

    Sets the point at which a file transfer should start; useful for resuming interrupted transfers. For nonstructured files, this is simply a decimal number. This command must immediately precede a data transfer command (RETR or STOR only); i.e. it must come after any PORT or PASV command.

    RETR
    Syntax: RETR remote-filename

    Begins transmission of a file from the remote host. Must be preceded by either a PORT command or a PASV command to indicate where the server should send data.

    RMD
    Syntax: RMD remote-directory

    Deletes the named directory on the remote host.

    RNFR
    Syntax: RNFR from-filename

    Used when renaming a file. Use this command to specify the file to be renamed; follow it with an RNTO command to specify the new name for the file.

    RNTO
    Syntax: RNTO to-filename

    Used when renaming a file. After sending an RNFR command to specify the file to rename, send this command to specify the new name for the file.

    SITE*
    Syntax: SITE site-specific-command

    Executes a site-specific command.

    SIZE
    Syntax: SIZE remote-filename

    Returns the size of the remote file as a decimal number.

    STAT
    Syntax: STAT [remote-filespec]

    If invoked without parameters, returns general status information about the FTP server process. If a parameter is given, acts like the LIST command, except that data is sent over the control connection (no PORT or PASV command is required).

    STOR
    Syntax: STOR remote-filename

    Begins transmission of a file to the remote site. Must be preceded by either a PORT command or a PASV command so the server knows where to accept data from.

    STOU
    Syntax: STOU

    Begins transmission of a file to the remote site; the remote filename will be unique in the current directory. The response from the server will include the filename.

    STRU
    Syntax: STRU structure-character

    Sets the file structure for transfer to one of:

    * F – File (no structure)
    * R – Record structure
    * P – Page structure

    The default structure is File.

    SYST
    Syntax: SYST

    Returns a word identifying the system, the word “Type:”, and the default transfer type (as would be set by the TYPE command). For example: UNIX Type: L8

    TYPE
    Syntax: TYPE type-character [second-type-character]

    Sets the type of file to be transferred. type-character can be any of:

    * A – ASCII text
    * E – EBCDIC text
    * I – image (binary data)
    * L – local format

    For A and E, the second-type-character specifies how the text should be interpreted. It can be:

    * N – Non-print (not destined for printing). This is the default if second-type-character is omitted.
    * T – Telnet format control (, , etc.)
    * C – ASA Carriage Control

    For L, the second-type-character specifies the number of bits per byte on the local system, and may not be omitted.

    USER
    Syntax: USER username

    Send this command to begin the login process. username should be a valid username on the system, or “anonymous” to initiate an anonymous login.
