ffttpp - ARPANET file transfer program
SSYYNNOOPPSSIISS
ffttpp [--vv] [--dd] [--ii] [--nn] [--gg] [_h_o_s_t]
DDEESSCCRRIIPPTTIIOONN
FFttpp is the user interface to the ARPANET standard File Transfer Protocol.
The program allows a user to transfer files to and from a remote network
site.
Options may be specified at the command line, or to the command inter-
preter.
--vv Verbose option forces ffttpp to show all responses from the remote
server, as well as report on data transfer statistics.
--nn Restrains ffttpp from attempting ``auto-login'' upon initial connec-
tion. If auto-login is enabled, ffttpp will check the ._n_e_t_r_c (see
below) file in the user's home directory for an entry describing an
account on the remote machine. If no entry exists, ffttpp will prompt
for the remote machine login name (default is the user identity on
the local machine), and, if necessary, prompt for a password and an
account with which to login.
--ii Turns off interactive prompting during multiple file transfers.
--dd Enables debugging.
--gg Disables file name globbing.
The client host with which ffttpp is to communicate may be specified on the
command line. If this is done, ffttpp will immediately attempt to establish
a connection to an FTP server on that host; otherwise, ffttpp will enter its
command interpreter and await instructions from the user. When ffttpp is
awaiting commands from the user the prompt `ftp>' is provided to the
user. The following commands are recognized by ffttpp:
!! [_c_o_m_m_a_n_d [_a_r_g_s]
Invoke an interactive shell on the local machine. If there are
arguments, the first is taken to be a command to execute
directly, with the rest of the arguments as its arguments.
$$ _m_a_c_r_o-_n_a_m_e[_a_r_g_s]
Execute the macro _m_a_c_r_o-_n_a_m_e that was defined with the mmaaccddeeff
command. Arguments are passed to the macro unglobbed.
aaccccoouunntt [_p_a_s_s_w_d]
Supply a supplemental password required by a remote system for
access to resources once a login has been successfully
completed. If no argument is included, the user will be
prompted for an account password in a non-echoing input mode.
aappppeenndd _l_o_c_a_l-_f_i_l_e [_r_e_m_o_t_e-_f_i_l_e]
Append a local file to a file on the remote machine. If
_r_e_m_o_t_e-_f_i_l_e is left unspecified, the local file name is used in
naming the remote file after being altered by any nnttrraannss or
nnmmaapp setting. File transfer uses the current settings for
ttyyppee, ffoorrmmaatt, mmooddee, and ssttrruuccttuurree.
aasscciiii Set the file transfer ttyyppee to network ASCII. This is the de-
fault type.
bbeellll Arrange that a bell be sounded after each file transfer command
is completed.
bbiinnaarryy Set the file transfer ttyyppee to support binary image transfer.
bbyyee Terminate the FTP session with the remote server and exit ffttpp.
An end of file will also terminate the session and exit.
ccaassee Toggle remote computer file name case mapping during mmggeett com-
mands. When ccaassee is on (default is off), remote computer file
names with all letters in upper case are written in the local
directory with the letters mapped to lower case.
ccdd _r_e_m_o_t_e-_d_i_r_e_c_t_o_r_y
Change the working directory on the remote machine to _r_e_m_o_t_e-
_d_i_r_e_c_t_o_r_y.
ccdduupp Change the remote machine working directory to the parent of
the current remote machine working directory.
cchhmmoodd _m_o_d_e _f_i_l_e-_n_a_m_e
Change the permission modes of the file _f_i_l_e-_n_a_m_e on the remote
sytem to _m_o_d_e.
cclloossee Terminate the FTP session with the remote server, and return to
the command interpreter. Any defined macros are erased.
ccrr Toggle carriage return stripping during ascii type file re-
trieval. Records are denoted by a carriage return/linefeed se-
quence during ascii type file transfer. When ccrr is on (the de-
fault), carriage returns are stripped from this sequence to
conform with the UNIX single linefeed record delimiter.
Records on non-UNIX remote systems may contain single
linefeeds; when an ascii type transfer is made, these linefeeds
may be distinguished from a record delimiter only when ccrr is
off.
ddeelleettee _r_e_m_o_t_e-_f_i_l_e
Delete the file _r_e_m_o_t_e-_f_i_l_e on the remote machine.
ddeebbuugg [_d_e_b_u_g-_v_a_l_u_e]
Toggle debugging mode. If an optional _d_e_b_u_g-_v_a_l_u_e is specified
it is used to set the debugging level. When debugging is on,
ffttpp prints each command sent to the remote machine, preceded by
the string `-->'
ddiirr [_r_e_m_o_t_e-_d_i_r_e_c_t_o_r_y] [_l_o_c_a_l-_f_i_l_e]
Print a listing of the directory contents in the directory,
_r_e_m_o_t_e-_d_i_r_e_c_t_o_r_y, and, optionally, placing the output in
_l_o_c_a_l-_f_i_l_e. If interactive prompting is on, ffttpp will prompt
the user to verify that the last argument is indeed the target
local file for receiving ddiirr output. If no directory is speci-
fied, the current working directory on the remote machine is
used. If no local file is specified, or _l_o_c_a_l-_f_i_l_e is output
comes to the terminal.
ddiissccoonnnneecctt
A synonym for _c_l_o_s_e.
ffoorrmm _f_o_r_m_a_t
Set the file transfer ffoorrmm to _f_o_r_m_a_t. The default format is
``file''.
ggeett _r_e_m_o_t_e-_f_i_l_e [_l_o_c_a_l-_f_i_l_e]
Retrieve the _r_e_m_o_t_e-_f_i_l_e and store it on the local machine. If
the local file name is not specified, it is given the same name
it has on the remote machine, subject to alteration by the
current ccaassee, nnttrraannss, and nnmmaapp settings. The current settings
for ttyyppee, ffoorrmm, mmooddee, and ssttrruuccttuurree are used while transferring
the file.
gglloobb Toggle filename expansion for mmddeelleettee, mmggeett and mmppuutt. If glob-
bing is turned off with gglloobb, the file name arguments are taken
literally and not expanded. Globbing for mmppuutt is done as in
csh(1). For mmddeelleettee and mmggeett, each remote file name is expand-
ed separately on the remote machine and the lists are not
merged. Expansion of a directory name is likely to be dif-
ferent from expansion of the name of an ordinary file: the ex-
act result depends on the foreign operating system and ftp
server, and can be previewed by doing `mls remote-files -'
Note: mmggeett and mmppuutt are not meant to transfer entire directory
subtrees of files. That can be done by transferring a tar(1)
archive of the subtree (in binary mode).
hhaasshh Toggle hash-sign (``#'') printing for each data block
transferred. The size of a data block is 1024 bytes.
hheellpp [_c_o_m_m_a_n_d]
Print an informative message about the meaning of _c_o_m_m_a_n_d. If
no argument is given, ffttpp prints a list of the known commands.
iiddllee [_s_e_c_o_n_d_s]
Set the inactivity timer on the remote server to _s_e_c_o_n_d_s
seconds. If _s_e_c_o_n_d_s is ommitted, the current inactivity timer
is printed.
llccdd [_d_i_r_e_c_t_o_r_y]
Change the working directory on the local machine. If no
_d_i_r_e_c_t_o_r_y is specified, the user's home directory is used.
llss [_r_e_m_o_t_e-_d_i_r_e_c_t_o_r_y] [_l_o_c_a_l-_f_i_l_e]
Print a listing of the contents of a directory on the remote
machine. The listing includes any system-dependent information
that the server chooses to include; for example, most UNIX
systems will produce output from the command `ls -l'. (See
also nnlliisstt. ) If _r_e_m_o_t_e-_d_i_r_e_c_t_o_r_y is left unspecified, the
current working directory is used. If interactive prompting is
on, ffttpp will prompt the user to verify that the last argument
is indeed the target local file for receiving llss output. If no
local file is specified, or if _l_o_c_a_l-_f_i_l_e is `--', the output is
sent to the terminal.
mmaaccddeeff _m_a_c_r_o-_n_a_m_e
Define a macro. Subsequent lines are stored as the macro
_m_a_c_r_o-_n_a_m_e; a null line (consecutive newline characters in a
file or carriage returns from the terminal) terminates macro
input mode. There is a limit of 16 macros and 4096 total char-
acters in all defined macros. Macros remain defined until a
cclloossee command is executed. The macro processor interprets `$'
and `\' as special characters. A `$' followed by a number (or
numbers) is replaced by the corresponding argument on the macro
invocation command line. A `$' followed by an `i' signals that
macro processor that the executing macro is to be looped. On
the first pass `$i' is replaced by the first argument on the
macro invocation command line, on the second pass it is re-
placed by the second argument, and so on. A `\' followed by
any character is replaced by that character. Use the `\' to
prevent special treatment of the `$'.
mmddeelleettee [_r_e_m_o_t_e-_f_i_l_e_s]
Delete the _r_e_m_o_t_e-_f_i_l_e_s on the remote machine.
mmddiirr _r_e_m_o_t_e-_f_i_l_e_s _l_o_c_a_l-_f_i_l_e
Like ddiirr, except multiple remote files may be specified. If
interactive prompting is on, ffttpp will prompt the user to verify
that the last argument is indeed the target local file for re-
ceiving mmddiirr output.
mmggeett _r_e_m_o_t_e-_f_i_l_e_s
Expand the _r_e_m_o_t_e-_f_i_l_e_s on the remote machine and do a ggeett for
each file name thus produced. See gglloobb for details on the
filename expansion. Resulting file names will then be pro-
cessed according to ccaassee, nnttrraannss, and nnmmaapp settings. Files are
transferred into the local working directory, which can be
changed with new local directories can be created with
mmkkddiirr _d_i_r_e_c_t_o_r_y-_n_a_m_e
Make a directory on the remote machine.
mmllss _r_e_m_o_t_e-_f_i_l_e_s _l_o_c_a_l-_f_i_l_e
Like nnlliisstt, except multiple remote files may be specified, and
the _l_o_c_a_l-_f_i_l_e must be specified. If interactive prompting is
on, ffttpp will prompt the user to verify that the last argument
is indeed the target local file for receiving mmllss output.
mmooddee [_m_o_d_e-_n_a_m_e]
Set the file transfer mmooddee to _m_o_d_e-_n_a_m_e. The default mode is
``stream'' mode.
mmooddttiimmee _f_i_l_e-_n_a_m_e
Show the last modification time of the file on the remote
machine.
mmppuutt _l_o_c_a_l-_f_i_l_e_s
Expand wild cards in the list of local files given as arguments
and do a ppuutt for each file in the resulting list. See gglloobb for
details of filename expansion. Resulting file names will then
be processed according to nnttrraannss and nnmmaapp settings.
nneewweerr _f_i_l_e-_n_a_m_e
Get the file only if the modification time of the remote file
is more recent that the file on the current system. If the file
does not exist on the current system, the remote file is
considered nneewweerr. Otherwise, this command is identical to _g_e_t.
nnlliisstt [_r_e_m_o_t_e-_d_i_r_e_c_t_o_r_y] [_l_o_c_a_l-_f_i_l_e]
Print a list of the files in a directory on the remote
machine. If _r_e_m_o_t_e-_d_i_r_e_c_t_o_r_y is left unspecified, the current
working directory is used. If interactive prompting is on, ffttpp
will prompt the user to verify that the last argument is indeed
the target local file for receiving nnlliisstt output. If no local
file is specified, or if _l_o_c_a_l-_f_i_l_e is the output is sent to
the terminal.
nnmmaapp [_i_n_p_a_t_t_e_r_n _o_u_t_p_a_t_t_e_r_n]
Set or unset the filename mapping mechanism. If no arguments
are specified, the filename mapping mechanism is unset. If
arguments are specified, remote filenames are mapped during
mmppuutt commands and ppuutt commands issued without a specified re-
mote target filename. If arguments are specified, local
filenames are mapped during mmggeett commands and ggeett commands is-
sued without a specified local target filename. This command
is useful when connecting to a non-UNIX remote computer with
different file naming conventions or practices. The mapping
follows the pattern set by _i_n_p_a_t_t_e_r_n and _o_u_t_p_a_t_t_e_r_n. [_I_n_p_a_t_-
_t_e_r_n]] is a template for incoming filenames (which may have al-
ready been processed according to the nnttrraannss and ccaassee set-
tings). Variable templating is accomplished by including the
sequences `$1', `$2', ..., `$9' in _i_n_p_a_t_t_e_r_n. Use `\' to
prevent this special treatment of the `$' character. All other
characters are treated literally, and are used to determine the
nnmmaapp [_i_n_p_a_t_t_e_r_n] variable values. For example, given _i_n_p_a_t_t_e_r_n
$1.$2 and the remote file name "mydata.data", $1 would have the
value "mydata", and $2 would have the value "data". The
_o_u_t_p_a_t_t_e_r_n determines the resulting mapped filename. The se-
quences `$1', `$2', ...., `$9' are replaced by any value
resulting from the _i_n_p_a_t_t_e_r_n template. The sequence `$0' is
replace by the original filename. Additionally, the sequence
`[_s_e_q_1, _s_e_q_2]' is replaced by [_s_e_q_1] if _s_e_q_1 is not a null
string; otherwise it is replaced by _s_e_q_2. For example, the
command
nmap $1.$2.$3 [$1,$2].[$2,file]
would yield the output filename "myfile.data" for input
filenames "myfile.data" and "myfile.data.old", "myfile.file"
for the input filename "myfile", and "myfile.myfile" for the
input filename ".myfile". Spaces may be included in
_o_u_t_p_a_t_t_e_r_n, as in the example: `nmap $1 sed "s/ *$//" > $1' .
Use the `\' character to prevent special treatment of the
`$','[','[', and `,' characters.
nnttrraannss [_i_n_c_h_a_r_s [_o_u_t_c_h_a_r_s]
Set or unset the filename character translation mechanism. If
no arguments are specified, the filename character translation
mechanism is unset. If arguments are specified, characters in
remote filenames are translated during mmppuutt commands and ppuutt
commands issued without a specified remote target filename. If
arguments are specified, characters in local filenames are
translated during mmggeett commands and ggeett commands issued without
a specified local target filename. This command is useful when
connecting to a non-UNIX remote computer with different file
naming conventions or practices. Characters in a filename
matching a character in _i_n_c_h_a_r_s are replaced with the
corresponding character in _o_u_t_c_h_a_r_s. If the character's posi-
tion in _i_n_c_h_a_r_s is longer than the length of _o_u_t_c_h_a_r_s, the
character is deleted from the file name.
ooppeenn _h_o_s_t [_p_o_r_t]
Establish a connection to the specified _h_o_s_t FTP server. An
optional port number may be supplied, in which case, ffttpp will
attempt to contact an FTP server at that port. If the aauuttoo--
llooggiinn option is on (default), ffttpp will also attempt to automat-
ically log the user in to the FTP server (see below).
pprroommpptt Toggle interactive prompting. Interactive prompting occurs
during multiple file transfers to allow the user to selectively
retrieve or store files. If prompting is turned off (default
is on), any mmggeett or mmppuutt will transfer all files, and any
mmddeelleettee will delete all files.
pprrooxxyy _f_t_p-_c_o_m_m_a_n_d
Execute an ftp command on a secondary control connection. This
command allows simultaneous connection to two remote ftp
servers for transferring files between the two servers. The
first pprrooxxyy command should be an ooppeenn, to establish the secon-
dary control connection. Enter the command "proxy ?" to see
other ftp commands executable on the secondary connection. The
following commands behave differently when prefaced by pprrooxxyy:
ooppeenn will not define new macros during the auto-login process,
cclloossee will not erase existing macro definitions, ggeett and mmggeett
transfer files from the host on the primary control connection
to the host on the secondary control connection, and ppuutt, mmppuutt,
and aappppeenndd transfer files from the host on the secondary con-
trol connection to the host on the primary control connection.
Third party file transfers depend upon support of the ftp pro-
tocol PASV command by the server on the secondary control con-
nection.
ppuutt _l_o_c_a_l-_f_i_l_e [_r_e_m_o_t_e-_f_i_l_e]
Store a local file on the remote machine. If _r_e_m_o_t_e-_f_i_l_e is
left unspecified, the local file name is used after processing
according to any nnttrraannss or nnmmaapp settings in naming the remote
file. File transfer uses the current settings for ttyyppee,
ffoorrmmaatt, mmooddee, and ssttrruuccttuurree.
ppwwdd Print the name of the current working directory on the remote
machine.
qquuiitt A synonym for bbyyee.
qquuoottee _a_r_g_1 _a_r_g_2 ...
The arguments specified are sent, verbatim, to the remote FTP
server.
rreeccvv _r_e_m_o_t_e-_f_i_l_e [_l_o_c_a_l-_f_i_l_e]
A synonym for get.
rreeggeett _r_e_m_o_t_e-_f_i_l_e [_l_o_c_a_l-_f_i_l_e]
Reget acts like get, except that if _l_o_c_a_l-_f_i_l_e exists and is
smaller than _r_e_m_o_t_e-_f_i_l_e, _l_o_c_a_l-_f_i_l_e is presumed to be a par-
tially transferred copy of _r_e_m_o_t_e-_f_i_l_e and the transfer is con-
tinued from the apparent point of failure. This command is use-
ful when transferring very large files over networks that are
prone to dropping connections.
rreemmootteehheellpp [_c_o_m_m_a_n_d-_n_a_m_e]
Request help from the remote FTP server. If a _c_o_m_m_a_n_d-_n_a_m_e is
specified it is supplied to the server as well.
rreemmootteessttaattuuss [_f_i_l_e-_n_a_m_e]
With no arguments, show status of remote machine. If _f_i_l_e-_n_a_m_e
is specified, show status of _f_i_l_e-_n_a_m_e on remote machine.
rreennaammee [_f_r_o_m] [_t_o]
Rename the file _f_r_o_m on the remote machine, to the file _t_o.
rreesseett Clear reply queue. This command re-synchronizes command/reply
sequencing with the remote ftp server. Resynchronization may
be necessary following a violation of the ftp protocol by the
remote server.
rreessttaarrtt _m_a_r_k_e_r
Restart the immediately following ggeett or ppuutt at the indicated
_m_a_r_k_e_r. On UNIX systems, marker is usually a byte offset into
the file.
rrmmddiirr _d_i_r_e_c_t_o_r_y-_n_a_m_e
Delete a directory on the remote machine.
rruunniiqquuee Toggle storing of files on the local system with unique
filenames. If a file already exists with a name equal to the
target local filename for a ggeett or mmggeett command, a ".1" is ap-
pended to the name. If the resulting name matches another ex-
isting file, a ".2" is appended to the original name. If this
process continues up to ".99", an error message is printed, and
the transfer does not take place. The generated unique
filename will be reported. Note that rruunniiqquuee will not affect
local files generated from a shell command (see below). The
default value is off.
sseenndd _l_o_c_a_l-_f_i_l_e [_r_e_m_o_t_e-_f_i_l_e]
A synonym for put.
sseennddppoorrtt
Toggle the use of PORT commands. By default, ffttpp will attempt
to use a PORT command when establishing a connection for each
data transfer. The use of PORT commands can prevent delays
when performing multiple file transfers. If the PORT command
fails, ffttpp will use the default data port. When the use of
PORT commands is disabled, no attempt will be made to use PORT
commands for each data transfer. This is useful for certain
FTP implementations which do ignore PORT commands but, in-
correctly, indicate they've been accepted.
ssiittee _a_r_g_1 _a_r_g_2 ...
The arguments specified are sent, verbatim, to the remote FTP
server as a SITE command.
ssiizzee _f_i_l_e-_n_a_m_e
Return size of _f_i_l_e-_n_a_m_e on remote machine.
ssttaattuuss Show the current status of ffttpp.
ssttrruucctt [_s_t_r_u_c_t-_n_a_m_e]
Set the file transfer _s_t_r_u_c_t_u_r_e to _s_t_r_u_c_t-_n_a_m_e. By default
``stream'' structure is used.
ssuunniiqquuee Toggle storing of files on remote machine under unique file
names. Remote ftp server must support ftp protocol STOU com-
mand for successful completion. The remote server will report
unique name. Default value is off.
ssyysstteemm Show the type of operating system running on the remote
machine.
tteenneexx Set the file transfer type to that needed to talk to TENEX
machines.
ttrraaccee Toggle packet tracing.
ttyyppee [_t_y_p_e-_n_a_m_e]
Set the file transfer ttyyppee to _t_y_p_e-_n_a_m_e. If no type is speci-
fied, the current type is printed. The default type is network
ASCII.
uummaasskk [_n_e_w_m_a_s_k]
Set the default umask on the remote server to _n_e_w_m_a_s_k. If
_n_e_w_m_a_s_k is ommitted, the current umask is printed.
uusseerr _u_s_e_r-_n_a_m_e [_p_a_s_s_w_o_r_d] [_a_c_c_o_u_n_t]
Identify yourself to the remote FTP server. If the _p_a_s_s_w_o_r_d is
not specified and the server requires it, ffttpp will prompt the
user for it (after disabling local echo). If an _a_c_c_o_u_n_t field
is not specified, and the FTP server requires it, the user will
be prompted for it. If an _a_c_c_o_u_n_t field is specified, an ac-
count command will be relayed to the remote server after the
login sequence is completed if the remote server did not re-
quire it for logging in. Unless ffttpp is invoked with ``auto-
login'' disabled, this process is done automatically on initial
connection to the FTP server.
vveerrbboossee Toggle verbose mode. In verbose mode, all responses from the
FTP server are displayed to the user. In addition, if verbose
is on, when a file transfer completes, statistics regarding the
efficiency of the transfer are reported. By default, verbose
is on.
?? [_c_o_m_m_a_n_d]
A synonym for help.
Command arguments which have embedded spaces may be quoted with quote `"'
marks.
AABBOORRTTIINNGG AA FFIILLEE TTRRAANNSSFFEERR
To abort a file transfer, use the terminal interrupt key (usually Ctrl-
C). Sending transfers will be immediately halted. Receiving transfers
will be halted by sending a ftp protocol ABOR command to the remote
server, and discarding any further data received. The speed at which
this is accomplished depends upon the remote server's support for ABOR
processing. If the remote server does not support the ABOR command, an
`ftp>' prompt will not appear until the remote server has completed
sending the requested file.
The terminal interrupt key sequence will be ignored when ffttpp has complet-
ed any local processing and is awaiting a reply from the remote server.
A long delay in this mode may result from the ABOR processing described
above, or from unexpected behavior by the remote server, including viola-
tions of the ftp protocol. If the delay results from unexpected remote
server behavior, the local ffttpp program must be killed by hand.
FFIILLEE NNAAMMIINNGG CCOONNVVEENNTTIIOONNSS
Files specified as arguments to ffttpp commands are processed according to
the following rules.
1) If the file name `--' is specified, the _s_t_d_i_n (for reading) or
_s_t_d_o_u_t (for writing) is used.
2) If the first character of the file name is `|', the remainder of
the argument is interpreted as a shell command. FFttpp then forks a
shell, using popen(3) with the argument supplied, and reads
(writes) from the stdout (stdin). If the shell command includes
spaces, the argument must be quoted; e.g. ``" ls -lt"''. A partic-
ularly useful example of this mechanism is: ``dir more''.
3) Failing the above checks, if ``globbing'' is enabled, local file
names are expanded according to the rules used in the csh(1); c.f.
the gglloobb command. If the ffttpp command expects a single local file
(.e.g. ppuutt), only the first filename generated by the "globbing"
operation is used.
4) For mmggeett commands and ggeett commands with unspecified local file
names, the local filename is the remote filename, which may be al-
tered by a ccaassee, nnttrraannss, or nnmmaapp setting. The resulting filename
may then be altered if rruunniiqquuee is on.
5) For mmppuutt commands and ppuutt commands with unspecified remote file
names, the remote filename is the local filename, which may be al-
tered by a nnttrraannss or nnmmaapp setting. The resulting filename may then
be altered by the remote server if ssuunniiqquuee is on.
FFIILLEE TTRRAANNSSFFEERR PPAARRAAMMEETTEERRSS
The FTP specification specifies many parameters which may affect a file
transfer. The ttyyppee may be one of ``ascii'', ``image'' (binary), ``ebcd-
ic'', and ``local byte size'' (for PDP-10's and PDP-20's mostly). FFttpp
supports the ascii and image types of file transfer, plus local byte size
8 for tteenneexx mode transfers.
FFttpp supports only the default values for the remaining file transfer
parameters: mmooddee, ffoorrmm, and ssttrruucctt.

The ._n_e_t_r_c file contains login and initialization information used by the
auto-login process. It resides in the user's home directory. The fol-
lowing tokens are recognized; they may be separated by spaces, tabs, or
new-lines:
mmaacchhiinnee _n_a_m_e
Identify a remote machine _n_a_m_e. The auto-login process
searches the ._n_e_t_r_c file for a mmaacchhiinnee token that matches the
remote machine specified on the ffttpp command line or as an ooppeenn
command argument. Once a match is made, the subsequent ._n_e_t_r_c
tokens are processed, stopping when the end of file is reached
or another mmaacchhiinnee or a ddeeffaauulltt token is encountered.
ddeeffaauulltt This is the same as mmaacchhiinnee _n_a_m_e except that ddeeffaauulltt matches
any name. There can be only one ddeeffaauulltt token, and it must be
after all mmaacchhiinnee tokens. This is normally used as:
default login anonymous password user@site
thereby giving the user _a_u_t_o_m_a_t_i_c anonymous ftp login to
machines not specified in ._n_e_t_r_c. This can be overridden by
using the --nn flag to disable auto-login.
llooggiinn _n_a_m_e
Identify a user on the remote machine. If this token is
present, the auto-login process will initiate a login using
the specified _n_a_m_e.
ppaasssswwoorrdd _s_t_r_i_n_g
Supply a password. If this token is present, the auto-login
process will supply the specified string if the remote server
requires a password as part of the login process. Note that
if this token is present in the ._n_e_t_r_c file for any user other
than _a_n_o_n_y_m_o_u_s, ffttpp will abort the auto-login process if the
._n_e_t_r_c is readable by anyone besides the user.
aaccccoouunntt _s_t_r_i_n_g
Supply an additional account password. If this token is
present, the auto-login process will supply the specified
string if the remote server requires an additional account
password, or the auto-login process will initiate an ACCT
command if it does not.
mmaaccddeeff _n_a_m_e
Define a macro. This token functions like the ffttpp mmaaccddeeff com-
mand functions. A macro is defined with the specified name;
its contents begin with the next ._n_e_t_r_c line and continue un-
til a null line (consecutive new-line characters) is encoun-
tered. If a macro named iinniitt is defined, it is automatically
executed as the last step in the auto-login process.

FFttpp utilizes the following environment variables.
HOME For default location of a ._n_e_t_r_c file, if one exists.
SHELL For default shell.

FFttpp appeared in 4.2 BSD.

Correct execution of many commands depends upon proper behavior by the
remote server.
An error in the treatment of carriage returns in the 4.2BSD UNIX ascii-
mode transfer code has been corrected. This correction may result in in-
correct transfers of binary files to and from 4.2BSD servers using the
ascii type. Avoid this problem by using the binary image type.
