ftp Command

Purpose:

Transfers files between a local and a remote host.

Syntax:

ftp [ -d ] [ -g ] [ -i ] [ -n ] [ -v ] [ -f ] [ -k realm] [-q[-C]][ HostName [
Port ] ]

Description:

The ftp command uses the File Transfer Protocol (FTP) to transfer files between
the local host and a remote host or between two remote hosts.

The FTP protocol allows data transfer between hosts that use dissimilar file
systems. Although the protocol provides a high degree of flexibility in
transferring data, it does not attempt to preserve file attributes (such as the
protection mode or modification times of a file) that are specific to a
particular file system. Moreover, the FTP protocol makes few assumptions about
the overall structure of a file system and does not provide or allow such
functions as recursively copying subdirectories.

Note: If you are transferring files between systems and need to preserve
file attributes or recursively copy subdirectories, use the rcp command.

Issuing Subcommands

At the ftp> prompt, you can enter subcommands to perform tasks such as listing
remote directories, changing the current local and remote directory,
transferring multiple files in a single request, creating and removing
directories, and escaping to the local shell to perform shell commands. See the
Subcommands section for a description of each subcommand.

If you execute the ftp command and do not specify the HostName parameter for a
remote host, the ftp command immediately displays the ftp> prompt and waits for
an ftp subcommand. To connect to a remote host, execute the open subcommand.
When the ftp command connects to the remote host, the ftp command then prompts
for the login name and password before displaying the ftp> prompt again. The
ftp command is unsuccessful if no password is defined at the remote host for
the login name.

The ftp command interpreter, which handles all subcommands entered at the ftp>
prompt, provides facilities that are not available with most file-transfer
programs, such as:

o Handling file-name parameters to ftp subcommands
o Collecting a group of subcommands into a single subcommand macro
o Loading macros from a $HOME/.netrc file

These facilities help simplify repetitive tasks and allow you to use the ftp
command in unattended mode.

The command interpreter handles file-name parameters according to the following
rules:

o If a - (hyphen) is specified for the parameter, standard input (stdin) is
used for read operations and standard output (stdout) is used for write
operations.
o If the preceding check does not apply and file-name expansion is enabled
(see the -g flag or the glob subcommand), the interpreter expands the file
name according to the rules of the C shell. When globbing is enabled and a
pattern-matching character is used in a subcommand that expects a single
file name, results may be different than expected.

For example, the append and put subcommands perform file-name expansion and
then use only the first file name generated. Other ftp subcommands, such as
cd, delete, get, mkdir, rename, and rmdir, do not perform file-name
expansion and take the pattern-matching characters literally.
o For the get, put, mget, and mput subcommands, the interpreter has the
ability to translate and map between different local and remote file-name
syntax styles (see the case, ntrans, and nmap subcommands) and the ability
to modify a local file name if it is not unique (see the runique
subcommand). Additionally, the ftp command can send instructions to a
remote ftpd server to modify a remote file name if it is not unique (see
the sunique subcommand).
o Use double quotes (" ") to specify parameters that include blank
characters.

Note: The ftp command interpreter does not support pipes. It also does
not necessarily support all multibyte-character file names.

To end an ftp session when you are running interactively, use the quit or bye
subcommand or the End of File (Ctrl-D) key sequence at the ftp> prompt. To end
a file transfer before it has completed, press the Interrupt key sequence. The
default Interrupt key sequence is Ctrl-C. The stty command can be used to
redefine this key sequence.

The ftp command normally halts transfers being sent (from the local host to the
remote host) immediately. The ftp command halts transfers being received (from
the remote host to the local host) by sending an FTP ABOR instruction to the
remote FTP server and discarding all incoming file transfer packets until the
remote server stops sending them. If the remote server does not support the
ABOR instruction, the ftp command does not display the ftp> prompt until the
remote server has sent all of the requested file. Additionally, if the remote
server does something unexpected, you may need to end the local ftp process.

Security and Automatic Login

If Standard is the current authentication method:

The ftp command also handles security by sending passwords to the remote host
and permits automatic login, file transfers, and logoff.

If you execute the ftp command and specify the host name (HostName) of a remote
host, the ftp command tries to establish a connection to the specified host. If
the ftp command connects successfully, the ftp command searches for a local
$HOME/.netrc file in your current directory or home directory. If the file
exists, the ftp command searches the file for an entry initiating the login
process and command macro definitions for the remote host. If the $HOME/.netrc
file or automatic login entry does not exist or if your system has been secured
with the securetcpip command, the ftp command prompts the user for a user name
and password. The command displays the prompt whether or not the HostName
parameter is specified on the command line.

Note: The queuing system does not support multibyte host names.

If the ftp command finds a $HOME/.netrc automatic login entry for the specified
host, the ftp command attempts to use the information in that entry to log in
to the remote host. The ftp command also loads any command macros defined in
the entry. In some cases (for example, when the required password is not listed
in an automatic login entry), the ftp command prompts for the password before
displaying the ftp> prompt.

Once the ftp command completes the automatic login, the ftp command executes
the init macro if the macro is defined in the automatic login entry. If the
init macro does not exist or does not contain a quit or bye subcommand, the ftp
command then displays the ftp> prompt and waits for a subcommand.

Note: The remote user name specified either at the prompt or in a
$HOME/.netrc file must exist and have a password defined at the remote
host. Otherwise, the ftp command fails.

If Kerberos 5 is the current authentication method:

The ftp command will use the extensions to ftp specifications as defined in
IETF draft document "draft-ietf-cat-ftpsec-09.txt". The FTP security extensions
will be implemented using the Generic Security Service API (GSSAPI) security
mechanism. The GSSAPI provides services independent to the underlying security
and communication mechanism. The GSSAPI is defined in rfc 1508 and 1509.

The ftp command will use the AUTH and ADAT commands to authenticate with the
ftpd daemon. If both support Kerberos authentication, then they will use the
local users DCE credentials to authenticate the user on the remote system. If
this fails and Standard authentication is configured on both systems, the
process described above will be used.

The HostName parameter is the name of the host machine to which files are
transferred. The optional Port parameter specifies the ID of the port through
which to transmit. (The /etc/services file specifies the default port.)

Flags:

-C Allows the user to specify that the outgoing file sent using the send_file
command must be cached in the Network Buffer Cache (NBC). This flag cannot be
used unless the -q flag is specified. This flag is only applicable when a file
is being sent out in the binary mode with no protection.

-d Sends debugging information about ftp command operations to the syslogd
daemon. If you specify the -d flag, you must edit the /etc/syslog.conf file and
add one of the following entries:

user.info FileName

OR

user.debug FileName

Note: The syslogd daemon debug level includes info level messages.

If you do not edit the /etc/syslog.conf file, no messages are produced. After
changing the /etc/syslog.conf file, run the refresh -s syslogd or kill -1
SyslogdPID command to inform the syslogd daemon of the changes to its
configuration file. For more information about debug levels, refer to the
/etc/syslog.conf file. Also, refer to the debug subcommand.

-g Disables the expansion of metacharacters in file names. Interpreting
metacharacters can be referred to as expanding (sometimes called globbing) a
file name. See the glob subcommand.

-i Turns off interactive prompting during multiple file transfers. See the
prompt, mget, mput, and mdelete subcommands for descriptions of prompting
during multiple file transfers.

-n Prevents an automatic login on the initial connection. Otherwise, the ftp
command searches for a $HOME/.netrc entry that describes the login and
initialization process for the remote host. See the user subcommand.

-q Allows the user to specify that the send_file subroutine must be used for
sending the file on the network. This flag is only applicable when a file is
being sent out in the binary mode with no protection.

-v Displays all the responses from the remote server and provides data transfer
statistics. This display mode is the default when the output of the ftp command
is to a terminal, such as the console or a display.

If stdin is not a terminal, the ftp command disables verbose mode unless the
user invoked the ftp command with the -v flag or issued the verbose subcommand.

-f Causes the credentials to be forwarded. This flag will be ignored if
Kerberos 5 is not the current authentication method.

-k realm Allows the user to specify the realm of the remote station if it is
different from the local systems realm. For these purposes, a realm is
synonymous with a DCE cell. This flag will be ignored if Kerberos 5 is not the
current authentication method.

Subcommands

The following ftp subcommands can be entered at the ftp> prompt. Use double
quotes (" ") to specify parameters that include blank characters.

![Command [Parameters]] Invokes an interactive shell on the local host. An
optional command, with one or more optional parameters, can be given with the
shell command.

$Macro [Parameters] Executes the specified macro, previously defined with the
macdef subcommand. Parameters are not expanded.

?[Subcommand] Displays a help message describing the subcommand. If you do not
specify a Subcommand parameter, the ftp command displays a list of known
subcommands.

account [Password] Sends a supplemental password that a remote host may require
before granting access to its resources. If the password is not supplied with
the command, the user is prompted for the password. The password is not
displayed on the screen.

append LocalFile [RemoteFile] Appends a local file to a file on the remote
host. If the remote file name is not specified, the local file name is used,
altered by any setting made with the ntrans subcommand or the nmap subcommand.
The append subcommand uses the current values for form, mode, struct, and type
subcommands while appending the file.

ascii Synonym for the type ascii subcommand.

bell Sounds a bell after the completion of each file transfer.

binary Synonym for the type binary subcommand.

block Synonym for the mode block subcommand.

bye Ends the file-transfer session and exits the ftp command. Same as the quit
subcommand.

carriage-control Synonym for the form carriage-control subcommand.

case Sets a toggle for the case of file names. When the case subcommand is On,
the ftp command changes remote file names displayed in all capital letters from
uppercase to lowercase when writing them in the local directory. The default is
Off (so the ftp command writes uppercase remote file names in uppercase in the
local directory).

cd RemoteDirectory Changes the working directory on the remote host to the
specified directory.

cdup Changes the working directory on the remote host to the parent of the
current directory.

close Ends the file-transfer session, but does not exit the ftp command.
Defined macros are erased. Same as the disconnect subcommand.

copylocal Toggles local copy. copylocal defaults to off. An effort is made by
ftp to make sure you do not zero out a file by ftp'ing it to itself (eg. same
hostname, same pathname). Turning copylocal ON bypasses this check.

cr Strips the carriage return character from a carriage return and line-feed
sequence when receiving records during ASCII-type file transfers. (The ftp
command terminates each ASCII-type record with a carriage return and line feed
during file transfers.)

Records on remote hosts with operating systems other than the one you are
running can have single line feeds embedded in records. To distinguish these
embedded line feeds from record delimiters, set the cr subcommand to Off. The
cr subcommand toggles between On and Off.

debug [0 | 1] Toggles debug record keeping On and Off. Specify debug or debug 1
to print each command sent to the remote host and save the restart control
file. Specify debug again, or debug 0, to stop the debug record keeping. The
Ctrl-C key sequence also saves the restart control file.

Specifying the debug subcommand sends debugging information about ftp command
operations to the syslogd daemon. If you specify the debug subcommand, you must
edit the /etc/syslog.conf file and add one of the following entries:

user.info FileName

OR

user.debug FileName

Note: The syslogd daemon debug level includes info level messages.

If you do not edit the /etc/syslog.conf file, no messages are produced. After
changing the /etc/syslog.conf file, run the refresh -s syslogd or kill -1
SyslogdPID command to inform the syslogd daemon of the changes to its
configuration file. For more information about debug levels, refer to the
/etc/syslog.conf file. Also, refer to the ftp -d flag.

delete RemoteFile Deletes the specified remote file.

dir [RemoteDirectory][LocalFile] Writes a listing of the contents of the
specified remote directory (RemoteDirectory) to the specified local file
(LocalFile). If the RemoteDirectory parameter is not specified, the dir
subcommand lists the contents of the current remote directory. If the LocalFile
parameter is not specified or is a - (hyphen), the dir subcommand displays the
listing on the local terminal.

disconnect Ends the file-transfer session but does not exit the ftp command.
Defined macros are erased. Same as the close subcommand.

ebcdic Synonym for the type ebcdic subcommand.

exp_cmd Toggles between conventional and experimental protocol commands. The
default is off.

file Synonym for the struct file subcommand.

form [ carriage-control | non-print | telnet ] Specifies the form of the file
transfer. The form subcommand modifies the type subcommand to send the file
transfer in the indicated form. Valid arguments are carriage-control,
non-print, and telnet.

carriage-control
Sets the form of the file transfer to carriage-control.
non-print
Sets the form of the file transfer to non-print.
telnet
Sets the form of the file transfer to Telnet. Telnet is a Transmission
Control Protocol/Internet Protocol (TCP/IP) protocol that opens connections
to a system.

get RemoteFile [LocalFile] Copies the remote file to the local host. If the
LocalFile parameter is not specified, the remote file name is used locally and
is altered by any settings made by the case, ntrans, and nmap subcommands. The
ftp command uses the current settings for the type, form, mode, and struct
subcommands while transferring the file.

glob Toggles file-name expansion (globbing) for the mdelete, mget, and mput
subcommands. If globbing is disabled, file-name parameters for these
subcommands are not expanded. When globbing is enabled and a pattern-matching
character is used in a subcommand that expects a single file name, results may
be different than expected.

For example, the append and put subcommands perform file-name expansion and
then use only the first file name generated. Other ftp subcommands, such as cd,
delete, get, mkdir, rename, and rmdir, do not perform file-name expansion and
take the pattern-matching characters literally.

Globbing for the mput subcommand is done locally in the same way as for the csh
command. For the mdelete and mget subcommands, each file name is expanded
separately at the remote machine and the lists are not merged. The expansion of
a directory name can be different from the expansion of a file name, depending
on the remote host and the ftp server.

To preview the expansion of a directory name, use the mls subcommand:

mls RemoteFile

To transfer an entire directory subtree of files, transfer a tar archive of the
subtree in binary form, rather than using the mget or mput subcommand.

hash Toggles hash sign (#) printing. When the hash subcommand is on, the ftp
command displays one hash sign for each data block (1024 bytes) transferred.

help [Subcommand] Displays help information. See the ? subcommand.

image Synonym for the type image subcommand.

lcd [Directory] Changes the working directory on the local host. If you do not
specify a directory, the ftp command uses your home directory.

local M Synonym for the type local M subcommand.

ls [RemoteDirectory] [LocalFile] Writes an abbreviated file listing of a remote
directory to a local file. If the RemoteDirectory parameter is not specified,
the ftp command lists the current remote directory. If the LocalFile parameter
is not specified or is a - (hyphen), the ftp command displays the listing on
the local terminal.

macdef Macro Defines a subcommand macro. Subsequent lines up to a null line
(two consecutive line feeds) are saved as the text of the macro. Up to 16
macros, containing at most 4096 characters for all macros, can be defined.
Macros remain defined until either redefined or a close subcommand is executed.

The $ (dollar sign) and \ (backslash) are special characters in ftp macros. A $
symbol followed by one or more numbers is replaced by the corresponding macro
parameter on the invocation line (see the $ subcommand). A $ symbol followed by
the letter i indicates that the macro is to loop, with the $i character
combination being replaced by consecutive parameters on each pass.

The first macro parameter is used on the first pass, the second parameter is
used on the second pass, and so on. A \ symbol prevents special treatment of
the next character. Use the \ symbol to turn off the special meanings of the $
and \. (backslash period) symbols.

mdelete RemoteFiles Expands the files specified by the RemoteFiles parameter at
the remote host and deletes the remote files.

mdir [RemoteDirectories LocalFile] Expands the directories specified by the
RemoteDirectories parameter at the remote host and writes a listing of the
contents of those directories to the file specified in the LocalFile parameter.
If the RemoteDirectories parameter contains a pattern-matching character, the
mdir subcommand prompts for a local file if none is specified. If the
RemoteDirectories parameter is a list of remote directories separated by
blanks, the last argument in the list must be either a local file name or a -
(hyphen).

If the LocalFile parameter is - (hyphen), the mdir subcommand displays the
listing on the local terminal. If interactive prompting is on (see the prompt
subcommand), the ftp command prompts the user to verify that the last parameter
is a local file and not a remote directory.

mget RemoteFiles Expands the RemoteFiles parameter at the remote host and
copies the indicated remote files to the current directory on the local host.
See the glob subcommand for more information on file-name expansion. The remote
file names are used locally and are altered by any settings made by the case,
ntrans, and nmap subcommands. The ftp command uses the current settings for the
form, mode, struct, and type subcommands while transferring the files.

mkdir [RemoteDirectory] Creates the directory specified in the RemoteDirectory
parameter on the remote host.

mls [RemoteDirectories LocalFile] Expands the directories specified in the
RemoteDirectories parameter at the remote host and writes an abbreviated file
listing of the indicated remote directories to a local file. If the
RemoteDirectories parameter contains a pattern-matching character, the mls
subcommand prompts for a local file if none is specified. If the
RemoteDirectories parameter is a list of remote directories separated by
blanks, the last argument in the list must be either a local file name or a -
(hyphen).

If the LocalFile parameter is - (hyphen), the mls subcommand displays the
listing on the local terminal. If interactive prompting is on (see the prompt
subcommand), the ftp command prompts the user to verify that the last parameter
is a local file and not a remote directory.

mode [ stream | block ] Sets file-transfer mode. If an argument is not
supplied, the default is stream.

block
Sets the file-transfer mode to block.
stream
Sets the file-transfer mode to stream.

modtime Shows the last modification time of the specified file on the remote
machine. If the ftp command is not connected to a host prior to execution, the
modtime subcommand terminates with an error message. The ftp command ignores
parameter beyond the first parameter. If the FileName parameter is not
specified, the ftp command prompts for a file name. If no file name is given,
the ftp command sends a usage message to standard output and terminates the
subcommand.

If the name specified by the FileName parameter exists on the remote host, and
the name specifies a file, then the ftp command sends a message containing the
last modification time of the file to standard output and terminates the
subcommand. If FileName specifies a directory, the ftp command sends an error
message to standard output and terminates the subcommand.

Note: The modtime subcommand interprets metacharacters when allowed.

mput [LocalFiles] Expands the files specified in the LocalFiles parameter at
the local host and copies the indicated local files to the remote host. See the
glob subcommand for more information on file-name expansion. The local file
names are used at the remote host and are altered by any settings made by the
ntrans and nmap subcommands. The ftp command uses the current settings for the
type, form, mode, and struct subcommands while transferring the files.

nlist [RemoteDirectory][LocalFile] Writes a listing of the contents of the
specified remote directory (RemoteDirectory) to the specified local file
(LocalFile). If the RemoteDirectory parameter is not specified, the nlist
subcommand lists the contents of the current remote directory. If the LocalFile
parameter is not specified or is a - (hyphen), the nlist subcommand displays
the listing on the local terminal.

nmap [InPattern OutPattern] Turns the file-name mapping mechanism On or Off. If
no parameters are specified, file-name mapping is turned off. If parameters are
specified, source file names are mapped for the mget and mput subcommands and
for the get and put subcommands when the destination file name is not
specified. This subcommand is useful when the local and remote hosts use
different file-naming conventions or practices. Mapping follows the pattern set
by the InPattern and OutPattern parameters.

The InPattern parameter specifies the template for incoming file names, which
may have already been processed according to the case and ntrans settings. The
template variables $1 through $9 can be included in the InPattern parameter.
All characters in the InPattern parameter, other than the $ (dollar sign) and
the \$ (backslash, dollar sign), are treated literally and are used as
delimiters between InPattern variables. For example, if the InPattern parameter
is $1.$2 and the remote file name is mydata.dat, the value of $1 is mydata and
the value of $2 is dat.

The OutPattern parameter determines the resulting file name. The variables $1
through $9 are replaced by their values as derived from the InPattern
parameter, and the variable $0 is replaced by the original file name.
Additionally, the sequence [Sequence1,Sequence2] is replaced by the value of
Sequence1, if Sequence1 is not null; otherwise, it is replaced by the value of
Sequence2. For example, the subcommand:

nmap $1.$2.$3 [$1,$2].[$2,file]

would yield myfile.data from myfile.data or myfile.data.old, myfile.file from
myfile, and myfile.myfile from .myfile. Use the \ (backslash) symbol to prevent
the special meanings of the $ (dollar sign), [ (left bracket), ] (right
bracket), and , (comma) in the OutPattern parameter.

non-print Synonym for the form non-print subcommand.

ntrans [InCharacters [OutCharacters]] Turns the file-name character translation
mechanism On and Off. If no parameters are specified, character translation is
turned off. If parameters are specified, characters in source file names are
translated for mget and mput subcommands and for get and put subcommands when
the destination file name is not specified.

This subcommand is useful when the local and remote hosts use different
file-naming conventions or practices. Character translation follows the pattern
set by the InCharacters and OutCharacters parameter. Characters in a source
file name matching characters in the InCharacters parameter are replaced by the
corresponding characters in the OutCharacters parameter.

If the string specified by the InCharacters parameter is longer than the string
specified by the OutCharacters parameter, the characters in the InCharacters
parameter are deleted if they have no corresponding character in the
OutCharacters parameter.

open HostName [Port] Establishes a connection to the FTP server at the host
specified by the HostName parameter. If the optional port number is specified,
the ftp command attempts to connect to a server at that port. If the automatic
login feature is set (that is, the -n flag was not specified on the command
line), the ftp command attempts to log in the user to the FTP server.

You must also have a $HOME/.netrc file with the correct information in it and
the correct permissions set. The .netrc file must be in your home directory.

passive Toggles passive mode for file transfers. When a file transfer command
(such as get, mget, put, or mput) is invoked with passive mode off, the ftp
server opens a data connection back to the client. In passive mode, the client
opens data connections to the server when sending or receiving data.

private Sets the protection level to "private." At this level, data is
integrity and confidentially protected.

prompt Toggles interactive prompting. If interactive prompting is on (the
default), the ftp command prompts for verification before retrieving, sending,
or deleting multiple files during the mget, mput, and mdelete subcommands.
Otherwise, the ftp command acts accordingly on all files specified.

protect This command returns the current level of protection.

proxy [Subcommand] Executes an ftp command on a secondary control connection.
This subcommand allows the ftp command to connect simultaneously to two remote
FTP servers for transferring files between the two servers. The first proxy
subcommand should be an open subcommand to establish the secondary control
connection. Enter the proxy ? subcommand to see the other ftp subcommands that
are executable on the secondary connection.

The following subcommands behave differently when prefaced by the proxy
subcommand:

o The open subcommand does not define new macros during the automatic login
process.
o The close subcommand does not erase existing macro definitions.
o The get and mget subcommands transfer files from the host on the primary
connection to the host on the secondary connection.
o The put, mput, and append subcommands transfer files from the host on the
secondary connection to the host on the primary connection.
o The restart subcommand can be handled by the proxy command.
o The status subcommand displays accurate information.

File transfers require that the FTP server on the secondary connection must
support the PASV (passive) instruction.

put LocalFile [RemoteFile] Stores a local file on the remote host. If you do
not specify the RemoteFile parameter, the ftp command uses the local file name
to name the remote file, and the remote file name is altered by any settings
made by the ntrans and nmap subcommands. The ftp command uses the current
settings for the type, form, mode, and struct subcommands while transferring
the files.

pwd Displays the name of the current directory on the remote host.

quit Closes the connection and exits the ftp command. Same as the bye
subcommand.

quote String Sends the string specified by the String parameter verbatim to the
remote host. Execute the remotehelp or quote help subcommand to display a list
of valid values for the String parameter.

Note: "Quoting" commands that involve data transfers can produce
unpredictable results.

record Synonym for the struct record subcommand.

recv RemoteFile [LocalFile] Copies the remote file to the local host. Same as
the get subcommand.

reinitialize Reinitializes an FTP session by flushing all I/O and allowing
transfers to complete. Resets all defaults as if a user had just started an FTP
session without logging in to a remote host.

remotehelp [Subcommand] Requests help from the remote FTP server.

rename FromName ToName Renames a file on the remote host.

reset Clears the reply queue. This subcommand resynchronizes the command
parsing.

restart get | put | append Restarts a file transfer at the point where the last
checkpoint was made. To run successfully, the subcommand must be the same as
the aborted subcommand, including structure, type, and form. Valid arguments
are get, put, and append.

rmdir RemoteDirectory Removes the remote directory specified by the
RemoteDirectory parameter at the remote host.

runique (ReceiveUnique) Toggles the facility for creating unique file names for
local destination files during get and mget subcommands. If this facility is
Off (the default), the ftp command overwrites local files. Otherwise, if a
local file has the same name as that specified for a local destination file,
the ftp command modifies the specified name of the local destination file with
.1. If a local file is already using the new name, the ftp command appends the
postfix .2 to the specified name. If a local file is already using this second
name, the ftp command continues incrementing the postfix until it either finds
a unique file name or reaches .99 without finding a unique file name. If the
ftp command cannot find a unique file name, the ftp command reports an error
and the transfer does not take place. Note that the runique subcommand does not
affect local file names generated from a shell command.

safe Sets the protection level to "safe." At this level, data is integrity
protected.

send LocalFile [RemoteFile] Stores a local file on the remote host. Same as the
put subcommand.

sendport Toggles the use of FTP PORT instructions. By default, the ftp command
uses a PORT instruction when establishing a connection for each data transfer.
When the use of PORT instructions is disabled, the ftp command does not use
PORT instructions for data transfers. The PORT instruction is useful when
dealing with FTP servers that ignore PORT instructions while incorrectly
indicating the instructions have been accepted.

site Args Displays or sets the idle time-out period, displays or sets the
file-creation umask, or changes the permissions of a file, using the chmod
command. Possible values for the Args parameter are umask and chmod.

size RemoteFile Displays the size in bytes of the remote file specified by the
RemoteFile parameter.

status Displays the current status of the ftp command as well as the status of
the subcommands.

stream Synonym for the mode stream subcommand.

struct [ file | record ] Sets the data transfer structure type. Valid arguments
are file and record.

file
Sets the data-transfer structure type to file.
record
Sets the data-transfer structure type to record.

sunique (Send/Store Unique) Toggles the facility for creating unique file names
for remote destination files during put and mput subcommands. If this facility
is off (the default), the ftp command overwrites remote files. Otherwise, if a
remote file has the same name as that specified for a remote destination file,
the remote FTP server modifies the name of the remote destination file. Note
that the remote server must support the STOU instruction.

system Shows the type of operating system running on the remote machine.

telnet Synonym for the form telnet subcommand.

tenex Synonym for the type tenex subcommand.

trace Toggles packet tracing.

type [ ascii | binary | ebcdic | image | local M | tenex ] Sets the
file-transfer type. Valid arguments are ascii, binary, ebcdic, image, local M,
and tenex. If an argument is not specified, the current type is printed. The
default type is ascii; the binary type can be more efficient than ascii.

ascii
Sets the file-transfer type to network ASCII. This type is the default. File
transfer may be more efficient with binary-image transfer. See the binary
argument for further information.
binary
Sets the file-transfer type to binary image. This type can be more efficient
than an ASCII transfer.
ebcdic
Sets the file-transfer type to EBCDIC.
image
Sets the file-transfer type to binary image. This type can be more efficient
than an ASCII transfer.
local M
Sets the file-transfer type to local. The M parameter defines the decimal
number of bits per machine word. This parameter does not have a default.
tenex
Sets the file-transfer type to that needed for TENEX machines.

user User [Password] [Account] Identifies the local user (User) to the remote
FTP server. If the Password or Account parameter is not specified and the
remote server requires it, the ftp command prompts for the password or account
locally. If the Account parameter is required, the ftp command sends it to the
remote server after the remote login process completes.

Note: Unless automatic login is disabled by specifying the -n flag on the
command line, the ftp command sends the User, Password, and Account
parameters automatically for the initial connection to the remote server.
You also need a .netrc file in your home directory in order to issue an
automatic login.

verbose Toggles verbose mode. When the verbose mode is on (the default), the
ftp command displays all responses from the remote FTP server. Additionally,
the ftp command displays statistics on all file transfers when the transfers
complete.

Examples:

1. To invoke the ftp command, log in to the system canopus, display local
help information, display remote help information, display status, toggle
the bell, prompt, runique, trace, and verbose subcommands, and then quit,
enter:

$ ftp canopus
