You are on the nsftools.com site　　This page originally appeared at http://www.dreamhaven.org/ftp-raw.html, but the last time I looked it wasn't there any more, so I posted a local copy for you here. If you were really looking for a list of commands for the Microsoft Windows command-line FTP client, pleaselook here instead.

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 requireit. Typically sent after aPASS command.
　　
ALLO
Syntax: ALLO size [R max-record-size]　　Allocates sufficient storage space to receive a file. If the maximumsize of a record also needs to be known, that is sent as a secondnumeric parameter following a space, the capital letter "R", and anotherspace.
　　
APPE
Syntax: APPE remote-filename　　Append data to the end of a file on the remote host. If the file doesnot already exist, it is created. This command must be preceded by aPORT orPASV command so that theserver 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 supportedcommands).
　　
LIST
Syntax: LIST [remote-filespec]　　If remote-filespec refers to a file, sends information about thatfile. Ifremote-filespec refers to a directory, sends informationabout each file in that directory.remote-filespec defaults to thecurrent directory. This command must be preceded by aPORT orPASV command.
　　
MDTM
Syntax: MDTM remote-filename　　Returns the last-modified time of the given file on the remote host inthe format "YYYYMMDDhhmmss":YYYY is thefour-digit year, MM is the month from 01 to 12,DD is the day of the month from 01 to 31,hh isthe hour from 00 to 23, mm is the minute from 00 to 59, andss 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 thecurrent directory), with no other information. Must be preceded by aPORT orPASV command.
　　
NOOP
Syntax: NOOP　　Does nothing except return a response.
　　
PASS
Syntax: PASS password　　After sending the USER command, send this command tocomplete the login process. (Note, however, that anACCTcommand may have to be used on some systems.)
　　
PASV
Syntax: PASV　　Tells the server to enter "passive mode". In passive mode, the server willwait for the client to establish a connection with it rather thanattempting to connect to a client-specified port. The server will respondwith the address of the port it is listeningon, with a message like:
227 Entering Passive Mode(a1,a2,a3,a4,p1,p2)
where a1.a2.a3.a4 is the IP address andp1*256+p2 is the port number.
　　
PORT
Syntax: PORTa1,a2,a3,a4,p1,p2　　Specifies the host and port to which the server should connect for the nextfile transfer. This is interpreted as IP addressa1.a2.a3.a4, portp1*256+p2.
　　
PWD
Syntax: PWD　　Returns the name of the current directory on the remote host.
　　
QUIT
Syntax: QUIT　　Terminates the command connection.

Syntax: REIN　　Reinitializes the command connection - cancels the currentuser/password/account information. Should be followed by aUSER command for another login.
　　
REST
Syntax: REST position　　Sets the point at which a file transfer should start; useful for resuminginterrupted transfers. For nonstructured files, this is simply a decimalnumber. This command must immediately precede a data transfer command(RETRor STOR only); i.e. it mustcome after anyPORT or PASV command.

SIZE
Syntax: SIZE remote-filename　　Returns the size of the remote file as a decimal number.
　　
STAT

STOR
Syntax: STOR remote-filename　　Begins transmission of a file to the remote site. Must be preceded byeither a PORT command or a PASVcommand so the server knows where to accept data from.
　　
STOU

• R - Record structure
  
• P - Page structure
  

The default structure is File.　　
SYST

TYPE
Syntax: TYPEtype-character [second-type-character]　　Sets the type of file to be transferred. type-character can be anyof:

• A - ASCII text
  
• E - EBCDIC text
  
• I - image (binary data)
  
• L - local format
  

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

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

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