DDEESSCCRRIIPPTTIIOONN
     ffttpp is the user interface to the Internet standard File Transfer Proto-
     col.  The program allows a user to transfer files to and from a remote
     network site.

     The last five arguments will fetch a file using the FTP or HTTP proto-
     cols, or by direct copying, into the current directory.  This is ideal
     for scripts.  Refer to _A_U_T_O_-_F_E_T_C_H_I_N_G _F_I_L_E_S below for more information.

     Options may be specified at the command line, or to the command inter-
     preter.

     --44       Forces ffttpp to only use IPv4 addresses.

     --66       Forces ffttpp to only use IPv6 addresses.

     --AA       Force active mode ftp.  By default, ffttpp will try to use passive
              mode ftp and fall back to active mode if passive is not support-
              ed by the server.  This option causes ffttpp to always use an ac-
              tive connection.  It is only useful for connecting to very old
              servers that do not implement passive mode properly.

     --aa       Causes ffttpp to bypass normal login procedure, and use an anony-
              mous login instead.

     --dd       Enables debugging.

     --ee       Disables command line editing.  This is useful for Emacs ange-
              ftp mode.

     --ff       Forces a cache reload for transfers that go through the FTP or
              HTTP proxies.

     --gg       Disables file name globbing.

     --ii       Turns off interactive prompting during multiple file transfers.

     --nn       Restrains ffttpp from attempting ``auto-login'' upon initial con-
              nection.  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 de-
              scribing 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.

     --NN _n_e_t_r_c
              Use _n_e_t_r_c instead of _~_/_._n_e_t_r_c.  Refer to _T_H_E _._n_e_t_r_c _F_I_L_E for
              more information.

     --oo _o_u_t_p_u_t
              When auto-fetching files, save the contents in _o_u_t_p_u_t.  _o_u_t_p_u_t
              is parsed according to the _F_I_L_E _N_A_M_I_N_G _C_O_N_V_E_N_T_I_O_N_S below.  If
              _o_u_t_p_u_t is not `-' or doesn't start with `|', then only the first
              file specified will be retrieved into _o_u_t_p_u_t; all other files
              will be retrieved into the basename of their remote name.

     --pp       Enable passive mode operation for use behind connection filter-
              ing firewalls.  This option has been deprecated as ffttpp now tries
              to use passive mode by default, falling back to active mode if
              the server does not support passive connections.

     --PP _p_o_r_t  Sets the port number to _p_o_r_t.

     --rr _w_a_i_t  Retry the connection attempt if it failed, pausing for _w_a_i_t sec-
              onds.

     --RR       Restart all non-proxied auto-fetches.

     --tt       Enables packet tracing.

     --TT _d_i_r_e_c_t_i_o_n,_m_a_x_i_m_u_m[,_i_n_c_r_e_m_e_n_t]
              Set the maximum transfer rate for _d_i_r_e_c_t_i_o_n to _m_a_x_i_m_u_m
              bytes/second, and if specified, the increment to _i_n_c_r_e_m_e_n_t
              bytes/second.  Refer to rraattee for more information.

     --uu _u_r_l _f_i_l_e [...]
              Upload files on the command line to _u_r_l where _u_r_l is one of the
              ftp URL types as supported by auto-fetch (with an optional tar-
              get filename for single file uploads), and _f_i_l_e is one or more
              local files to be uploaded.

     --vv       Enable vveerrbboossee and pprrooggrreessss.  This is the default if output is
              to a terminal (and in the case of pprrooggrreessss, ffttpp is the fore-
              ground process).  Forces ffttpp to show all responses from the re-
              mote server, as well as report on data transfer statistics.

     --VV       Disable vveerrbboossee and pprrooggrreessss, overriding the default of enabled
              when output is to a terminal.

     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 us-
     er.  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 com-
                 mand 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 ex-
                 it.

     ccaassee        Toggle remote computer file name case mapping during ggeett,
                 mmggeett and mmppuutt commands.  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 _r_e_m_o_t_e_-_f_i_l_e
                 Change the permission modes of the file _r_e_m_o_t_e_-_f_i_l_e on the
                 remote system 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
                 sequence during ascii type file transfer.  When ccrr is on (the
                 default), 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 line-
                 feeds; when an ascii type transfer is made, these linefeeds
                 may be distinguished from a record delimiter only when ccrr is
                 off.

     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 speci-
                 fied 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 `-->'

     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.

     ddiirr [_r_e_m_o_t_e_-_p_a_t_h [_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 informa-
                 tion that the server chooses to include; for example, most
                 UNIX systems will produce output from the command `ls -l'.
                 If _r_e_m_o_t_e_-_p_a_t_h is left unspecified, the current working di-
                 rectory 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 ddiirr 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.

     ddiissccoonnnneecctt  A synonym for cclloossee.

     eeddiitt        Toggle command line editing, and context sensitive command
                 and file completion.  This is automatically enabled if input
                 is from a terminal, and disabled otherwise.

     eeppssvv44       Toggle the use of the extended EPSV and EPRT commands on IPv4
                 connections; first try EPSV / EPRT, and then PASV / PORT.
                 This is enabled by default.  If an extended command fails
                 then this option will be temporarily disabled for the dura-
                 tion of the current connection, or until eeppssvv44 is executed
                 again.

     eexxiitt        A synonym for bbyyee.

     ffeeaattuurreess    Display what features the remote server supports (using the
                 FEAT command).

     ffggeett _l_o_c_a_l_f_i_l_e
                 Retrieve the files listed in _l_o_c_a_l_f_i_l_e, which has one line
                 per filename.

     ffoorrmm _f_o_r_m_a_t
                 Set the file transfer ffoorrmm to _f_o_r_m_a_t.  The default (and only
                 supported) format is ``non-print''.

     ffttpp _h_o_s_t [_p_o_r_t]
                 A synonym for ooppeenn.

     ggaattee [_h_o_s_t [_p_o_r_t]]
                 Toggle gate-ftp mode, which used to connect through the TIS
                 FWTK and Gauntlet ftp proxies.  This will not be permitted if
                 the gate-ftp server hasn't been set (either explicitly by the
                 user, or from the FTPSERVER environment variable).  If _h_o_s_t
                 is given, then gate-ftp mode will be enabled, and the gate-
                 ftp server will be set to _h_o_s_t.  If _p_o_r_t is also given, that
                 will be used as the port to connect to on the gate-ftp serv-
                 er.

     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, mmppuutt, and
                 mmrreeggeett.  If globbing 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, mmggeett, and mmrreeggeett,
                 each remote file name is expanded separately on the remote
                 machine and the lists are not merged.  Expansion of a direc-
                 tory name is likely to be different from expansion of the
                 name of an ordinary file: the exact result depends on the
                 foreign operating system and ftp server, and can be previewed
                 by doing `mls remote-files -' Note: mmggeett, mmppuutt and mmrreeggeett are
                 not meant to transfer entire directory subtrees of files.
                 That can be done by transferring a tar(1) archive of the sub-
                 tree (in binary mode).

     hhaasshh [_s_i_z_e]
                 Toggle hash-sign (``#'') printing for each data block trans-
                 ferred.  The size of a data block defaults to 1024 bytes.
                 This can be changed by specifying _s_i_z_e in bytes.  Enabling
                 hhaasshh disables pprrooggrreessss.

     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 com-
                 mands.

     iiddllee [_s_e_c_o_n_d_s]
                 Set the inactivity timer on the remote server to _s_e_c_o_n_d_s sec-
                 onds.  If _s_e_c_o_n_d_s is omitted, the current inactivity timer is
                 printed.

     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
                 characters in all defined macros.  Macros remain defined un-
                 til a cclloossee command is executed.  The macro processor inter-
                 prets `$' and `\' as special characters.  A `$' 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 replaced by the second argument, and so on.
                 A `\' followed by any character is replaced by that charac-
                 ter.  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 ver-
                 ify that the last argument is indeed the target local file
                 for receiving 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
                 processed according to ccaassee, nnttrraannss, and nnmmaapp settings.
                 Files are transferred into the local working directory, which
                 can be changed with `lcd directory'; new local directories
                 can be created with `! mkdir directory'.

     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 llss, 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 argu-
                 ment is indeed the target local file for receiving mmllss out-
                 put.

     mmllssdd [_r_e_m_o_t_e_-_p_a_t_h]
                 Display the contents of _r_e_m_o_t_e_-_p_a_t_h (which should default to
                 the current directory if not given) in a machine-parsable
                 form, using MLSD.  The format of display can be changed with
                 `remopts mlst ...'.

     mmllsstt [_r_e_m_o_t_e_-_p_a_t_h]
                 Display the details about _r_e_m_o_t_e_-_p_a_t_h (which should default
                 to the current directory if not given) in a machine-parsable
                 form, using MLST.  The format of display can be changed with
                 `remopts mlst ...'.

                 Set the file transfer mmooddee to _m_o_d_e_-_n_a_m_e.  The default (and
                 only supported) mode is ``stream''.

     mmooddttiimmee _r_e_m_o_t_e_-_f_i_l_e
                 Show the last modification time of the file on the remote ma-

                 Expand wild cards in the list of local files given as argu-
                 ments 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.

     mmrreeggeett _r_e_m_o_t_e_-_f_i_l_e_s

     nneewweerr _r_e_m_o_t_e_-_f_i_l_e [_l_o_c_a_l_-_f_i_l_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

                 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
                 issued without a specified local target filename.  This com-
                 mand 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.

                 settings).  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 de-
                 termine 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 file-
                 name.  The sequences `$1', `$2', ...., `$9' are replaced by
                 any value resulting from the _i_n_p_a_t_t_e_r_n template.  The se-
                 quence `$0' is replace by the original filename.  Additional-
                 ly, 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 file-
                 names "myfile.data" and "myfile.data.old", "myfile.file" for
                 the input filename "myfile", and "myfile.myfile" for the in-
                 put 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 trans-
                 lation mechanism is unset.  If arguments are specified, char-
                 acters in remote filenames are translated during mmppuutt com-
                 mands and ppuutt commands issued without a specified remote tar-
                 get filename.  If arguments are specified, characters in lo-
                 cal 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 position 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 auto-
                 matically log the user in to the FTP server (see below).

     ppaaggee _f_i_l_e   Retrieve ffiillee and display with the program specified by the

     ppaassssiivvee [aauuttoo]
                 Toggle passive mode (if no arguments are given).  If aauuttoo is
                 given, act as if FTPMODE is set to `auto'.  If passive mode
                 is turned on (default), ffttpp will send a PASV command for all
                 data connections instead of a PORT command.  The PASV command
                 requests that the remote server open a port for the data con-
                 nection and return the address of that port.  The remote
                 server listens on that port and the client connects to it.
                 When using the more traditional PORT command, the client lis-
                 tens on a port and sends that address to the remote server,
                 who connects back to it.  Passive mode is useful when using
                 ffttpp through a gateway router or host that controls the direc-
                 tionality of traffic.  (Note that though FTP servers are re-
                 quired to support the PASV command by RFC 1123, some do not.)

     pprrooggrreessss    Toggle display of transfer progress bar.  The progress bar
                 will be disabled for a transfer that has _l_o_c_a_l_-_f_i_l_e as `--' or
                 a command that starts with `|'.  Refer to _F_I_L_E _N_A_M_I_N_G
                 _C_O_N_V_E_N_T_I_O_N_S for more information.  Enabling pprrooggrreessss disables
                 hhaasshh.

     pprroommpptt      Toggle interactive prompting.  Interactive prompting occurs
                 during multiple file transfers to allow the user to selec-
                 tively 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.

                 When prompting is on, the following commands are available at
                 a prompt:

                       aa   Answer `yes' to the current file, and automatically
                           answer `yes' to any remaining files for the current
                           command.

                       nn   Answer `no', and do not transfer the file.

                       pp   Answer `yes' to the current file, and turn off
                           prompt mode (as is ``prompt off'' had been given).

                       qq   Terminate the current operation.

                       yy   Answer `yes', and transfer the file.

                       ??   Display a help message.

                 Any other reponse will answer `yes' to the current file.

     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 sec-
                 ondary control connection.  Enter the command "proxy ?" to
                 see other FTP commands executable on the secondary connec-
                 tion.  The following commands behave differently when pref-
                 aced by pprrooxxyy: ooppeenn will not define new macros during the au-
                 to-login process, cclloossee will not erase existing macro defini-
                 tions, ggeett and mmggeett transfer files from the host on the pri-
                 mary control connection to the host on the secondary control
                 connection, and ppuutt, mmppuutt, and aappppeenndd transfer files from the
                 host on the secondary control connection to the host on the
                 primary control connection.  Third party file transfers de-
                 pend upon support of the FTP protocol PASV command by the
                 server on the secondary control connection.

     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 process-
                 ing 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.

     rraattee _d_i_r_e_c_t_i_o_n [_m_a_x_i_m_u_m [_i_n_c_r_e_m_e_n_t]]
                 Throttle the maximum transfer rate to _m_a_x_i_m_u_m bytes/second.
                 If _m_a_x_i_m_u_m is 0, disable the throttle.

                 _d_i_r_e_c_t_i_o_n may be one of:
                       aallll  Both directions.
                       ggeett  Incoming transfers.
                       ppuutt  Outgoing transfers.

                 _m_a_x_i_m_u_m can by modified on the fly by _i_n_c_r_e_m_e_n_t bytes (de-
                 fault: 1024) each time a given signal is received:

                       SIGUSR1  Increment _m_a_x_i_m_u_m by _i_n_c_r_e_m_e_n_t bytes.

                       SIGUSR2  Decrement _m_a_x_i_m_u_m by _i_n_c_r_e_m_e_n_t bytes.  The re-
                                sult must be a positive number.

                 If _m_a_x_i_m_u_m is not supplied, the current throttle rates are
                 displayed.

                 Note: rraattee is not yet implemented for ascii mode transfers.

     rrccvvbbuuff _s_i_z_e
                 Set the size of the socket receive buffer to _s_i_z_e.

     rreeccvv _r_e_m_o_t_e_-_f_i_l_e [_l_o_c_a_l_-_f_i_l_e]
                 A synonym for ggeett.

     rreeggeett _r_e_m_o_t_e_-_f_i_l_e [_l_o_c_a_l_-_f_i_l_e]
                 rreeggeett acts like ggeett, 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
                 continued from the apparent point of failure.  This command
                 is useful when transferring very large files over networks
                 that are prone to dropping connections.

     rreemmooppttss _c_o_m_m_a_n_d [_c_o_m_m_a_n_d_-_o_p_t_i_o_n_s]
                 Set options on the remote FTP server for _c_o_m_m_a_n_d to _c_o_m_m_a_n_d_-
                 _o_p_t_i_o_n_s (whose absence is handled on a command-specific ba-
                 sis).  Remote FTP commands known to support options include:
                 `MLST' (used for MLSD and MLST).

     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/re-
                 ply 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 in-
                 to the file.

     rrhheellpp [_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.

     rrmmddiirr _d_i_r_e_c_t_o_r_y_-_n_a_m_e
                 Delete a directory on the remote machine.

     rrssttaattuuss [_r_e_m_o_t_e_-_f_i_l_e]
                 With no arguments, show status of remote machine.  If _r_e_m_o_t_e_-
                 _f_i_l_e is specified, show status of _r_e_m_o_t_e_-_f_i_l_e on remote ma-
                 chine.

     rruunniiqquuee     Toggle storing of files on the local system with unique file-
                 names.  If a file already exists with a name equal to the
                 target local filename for a ggeett or mmggeett command, a ".1" is
                 appended to the name.  If the resulting name matches another
                 existing 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 be-
                 low).  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 ppuutt.

     sseennddppoorrtt    Toggle the use of PORT commands.  By default, ffttpp will at-
                 tempt 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, incorrectly, indicate they've been accepted.

     sseett [_o_p_t_i_o_n _v_a_l_u_e]
                 Set _o_p_t_i_o_n to _v_a_l_u_e.  If _o_p_t_i_o_n and _v_a_l_u_e are not given, dis-
                 play all of the options and their values.  The currently sup-
                 ported options are:

                       anonpass    Defaults to $FTPANONPASS

                       ftp_proxy   Defaults to $ftp_proxy.

                       http_proxy  Defaults to $http_proxy.

     ssiizzee _r_e_m_o_t_e_-_f_i_l_e
                 Return size of _r_e_m_o_t_e_-_f_i_l_e on remote machine.

     ssnnddbbuuff _s_i_z_e

     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.  The default
                 (and only supported) structure is ``file''.

     ssuunniiqquuee     Toggle storing of files on remote machine under unique file
                 names.  The remote FTP server must support FTP protocol STOU
                 command for successful completion.  The remote server will
                 report unique name.  Default value is off.

                 Set the file transfer ttyyppee to _t_y_p_e_-_n_a_m_e.  If no type is spec-
                 ified, the current type is printed.  The default type is net-
                 work 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 omitted, the current umask is printed.

                 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 speci-
                 fied, an account command will be relayed to the remote server
                 after the login sequence is completed if the remote server
                 did not require it for logging in.  Unless ffttpp is invoked
                 with ``auto-login'' disabled, this process is done automati-
                 cally on initial connection to the FTP server.

     vveerrbboossee     Toggle verbose mode.  In verbose mode, all responses from the

                 bose is on, when a file transfer completes, statistics re-
                 garding the efficiency of the transfer are reported.  By de-

     Command arguments which have embedded spaces may be quoted with quote `"'
     marks.

     Commands which toggle settings can take an explicit oonn or ooffff argument to
     force the setting appropriately.

     Commands which take a byte count as an argument (e.g., hhaasshh, rraattee, and
     xxffeerrbbuuff) support an optional suffix on the argument which changes the in-
     terpretation of the argument.  Supported suffixes are:
           b    Causes no modification. (Optional)
           k    Kilo; multiply the argument by 1024
           m    Mega; multiply the argument by 1048576
           g    Giga; multiply the argument by 1073741824

     If ffttpp receives a SIGINFO (see the ``status'' argument of stty(1)) or
     SIGQUIT signal whilst a transfer is in progress, the current transfer
     rate statistics will be written to the standard error output, in the same
     format as the standard completion message.

AAUUTTOO--FFEETTCCHHIINNGG FFIILLEESS
     In addition to standard commands, this version of ffttpp supports an auto-
     fetch feature.  To enable auto-fetch, simply pass the list of host-
     names/files on the command line.

     The following formats are valid syntax for an auto-fetch element:

     [user@]host:[path][/]
           ``Classic'' FTP format.

           If _p_a_t_h contains a glob character and globbing is enabled, (see
           gglloobb), then the equivalent of `mget path' is performed.

           If the directory component of _p_a_t_h contains no globbing characters,
           it is stored locally with the name basename (see basename(1)) of
           ppaatthh, in the current directory.  Otherwise, the full remote name is
           used as the local name, relative to the local root directory.

     ftp://[user[:password]@]host[:port]/path[/][;type=X]
           An FTP URL, retrieved using the FTP protocol if sseett ffttpp__pprrooxxyy isn't
           defined.  Otherwise, transfer the URL using HTTP via the proxy de-
           fined in sseett ffttpp__pprrooxxyy.  If sseett ffttpp__pprrooxxyy isn't defined and _u_s_e_r is
           given, login as _u_s_e_r.  In this case, use _p_a_s_s_w_o_r_d if supplied, oth-
           erwise prompt the user for one.

           In order to be compliant with RRFFCC 11773388, ffttpp strips the leading `/'
           from _p_a_t_h, resulting in a transfer relative from the default login
           directory of the user.  If the _/ directory is required, use a lead-
           ing path of ``%2F''.  If a user's home directory is required (and
           the remote server supports the syntax), use a leading path of
           ``%7Euser/''.  For example, to retrieve _/_e_t_c_/_m_o_t_d from `localhost'
           as the user `myname' with the password `mypass', use
           ``ftp://myname:mypass@localhost/%2fetc/motd''

           If a suffix of `;type=A' or `;type=I' is supplied, then the trans-
           fer type will take place as ascii or binary (respectively).  The
           default transfer type is binary.

     http://[user[:password]@]host[:port]/path
           An HTTP URL, retrieved using the HTTP protocol.  If sseett hhttttpp__pprrooxxyy
           is defined, it is used as a URL to an HTTP proxy server.  If HTTP
           authorisation is required to retrieve _p_a_t_h, and `user' (and option-
           ally `password') is in the URL, use them for the first attempt to
           authenticate.

     file:///path
           A local URL, copied from _/_p_a_t_h.

     Unless noted otherwise above, and --oo _o_u_t_p_u_t is not given, the file is
     stored in the current directory as the basename(1) of _p_a_t_h.

     If a classic format or an FTP URL format has a trailing `/' or an empty
     _p_a_t_h component, then ffttpp will connect to the site and ccdd to the directory
     given as the path, and leave the user in interactive mode ready for fur-
     ther input.  This will not work if sseett ffttpp__pprrooxxyy is being used.

     Direct HTTP transfers use HTTP 1.1.  Proxied FTP and HTTP transfers use
     HTTP 1.0.

     If --RR is given, all auto-fetches that don't go via the FTP or HTTP prox-
     ies will be restarted.  For FTP, this is implemented by using rreeggeett in-
     stead of ggeett.  For HTTP, this is implemented by using the `Range: bytes='
     HTTP/1.1 directive.

     If WWW or proxy WWW authentication is required, you will be prompted to
     enter a username and password to authenticate with.

     When specifying IPv6 numeric addresses in a URL, you need to surround the
     address in square brackets.  E.g.: ``ftp://[::1]:21/''.  This is because
     colons are used in IPv6 numeric address as well as being the separator
     for the port number.

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 an 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, the
     prompt will not appear until the remote server has completed sending the
     requested file.

     If the terminal interrupt key sequence is used whilst ffttpp is awaiting a
     reply from the remote server for the ABOR processing, then the connection
     will be closed.  This is different from the traditional behaviour (which
     ignores the terminal interrupt during this phase), but is considered more
     useful.

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 argu-
          ment must be quoted; e.g.  ``"| ls -lt"''.  A particularly 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" op-
          eration 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),
     ``ebcdic'', 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 pa-
     rameters: mmooddee, ffoorrmm, and ssttrruucctt.

TTHHEE ..nneettrrcc FFIILLEE
     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, unless
     overridden with the --NN _n_e_t_r_c option, or specified in the NETRC environ-
     ment variable.  The following tokens are recognized; they may be separat-
     ed by spaces, tabs, or new-lines:

     mmaacchhiinnee _n_a_m_e
               Identify a remote machine _n_a_m_e.  The auto-login process search-
               es 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 an-
               other 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 an automatic anonymous FTP login to ma-
               chines not specified in _._n_e_t_r_c.  This can be overridden by us-
               ing the --nn flag to disable auto-login.

     llooggiinn _n_a_m_e
               Identify a user on the remote machine.  If this token is pre-
               sent, 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 pre-
               sent, 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 until
               a blank line (consecutive new-line characters) is encountered.
               If a macro named iinniitt is defined, it is automatically executed
               as the last step in the auto-login process.

CCOOMMMMAANNDD LLIINNEE EEDDIITTIINNGG
     ffttpp supports interactive command line editing, via the editline(3) li-
     brary.  It is enabled with the eeddiitt command, and is enabled by default if
     input is from a tty.  Previous lines can be recalled and edited with the
     arrow keys, and other GNU Emacs-style editing keys may be used as well.

     The editline(3) library is configured with a _._e_d_i_t_r_c file - refer to
     editrc(5) for more information.

     An extra key binding is available to ffttpp to provide context sensitive
     command and filename completion (including remote file completion).  To
     use this, bind a key to the editline(3) command ffttpp--ccoommpplleettee.  By de-
     fault, this is bound to the TAB key.

CCOOMMMMAANNDD LLIINNEE PPRROOMMPPTT
     By default, ffttpp displays a command line prompt of ``ftp>'' to the user.
     This can be changed with the sseett pprroommpptt command.

     A prompt can be displayed on the right side of the screen (after the com-
     mand input) with the sseett rrpprroommpptt command.

     The following formatting sequences are replaced by the given information:

           %/   The current remote working directory.

           %c[[0]_n], %.[[0]_n]
                The trailing component of the current remote working directo-
                ry, or _n trailing components if a digit _n is given.  If _n be-
                gins with `0', the number of skipped components precede the
                trailing component(s) in the format ``/_<_s_k_i_p_p_e_d_>trailing''
                (for `%c') or ``...trailing'' (for `%.').

           %M   The remote host name.

           %m   The remote host name, up to the first `.'.

           %n   The remote user name.

           %%   A single `%'.

EENNVVIIRROONNMMEENNTT

     FTPSERVER      Host to use as gate-ftp server when ggaattee is enabled.

     FTPSERVERPORT  Port to use when connecting to gate-ftp server when ggaattee
                    is enabled.  Default is port returned by a ggeettsseerrvvbbyynnaammee()
                    lookup of ``ftpgate/tcp''.

     HOME           For default location of a _._n_e_t_r_c file, if one exists.

     NETRC          An alternate location of the _._n_e_t_r_c file.

     PAGER          Used by various commands to display files.  Defaults to
                    more(1) if empty or not set.

     SHELL          For default shell.

     ftp_proxy      URL of FTP proxy to use when making FTP URL requests (if
                    not defined, use the standard FTP protocol).

                    _N_O_T_E: this is not used for interactive sessions, only for
                    command-line fetches.

     http_proxy     URL of HTTP proxy to use when making HTTP URL requests.
                    If proxy authentication is required and there is a user-
                    name and password in this URL, they will automatically be
                    used in the first attempt to authenticate to the proxy.

                    Note that the use of a username and password in ftp_proxy
                    and http_proxy may be incompatible with other programs
                    that use it (such as lynx(1)).

                    _N_O_T_E: this is not used for interactive sessions, only for
                    command-line fetches.

     no_proxy       A space or comma separated list of hosts (or domains) for
                    which proxying is not to be used.  Each entry may have an
                    optional trailing ":port", which restricts the matching to
                    connections to that port.

HHIISSTTOORRYY
     The ffttpp command appeared in 4.2BSD.

     Various features such as command line editing, context sensitive command
     and file completion, dynamic progress bar, automatic fetching of files
     and URLs, modification time preservation, transfer rate throttling, con-
     figurable command line prompt, and other enhancements over the standard
     BSD ffttpp were implemented in NetBSD 1.3 and later releases by Luke Mewburn
     <lukem@netbsd.org>.

     IPv6 support was added by the WIDE/KAME project (but may not be present
     in all non-NetBSD versions of this program, depending if the operating
     system supports IPv6 in a similar manner to KAME).

BBUUGGSS
     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 ascii-mode
     transfer code has been corrected.  This correction may result in incor-
     rect transfers of binary files to and from 4.2BSD servers using the ascii
     type.  Avoid this problem by using the binary image type.

     ffttpp assumes that all IPv4 mapped addresses (IPv6 addresses with a form
     like ::ffff:10.1.1.1) indicate IPv4 destinations which can be handled by
     AF_INET sockets.  However, in certain IPv6 network configurations, this
     assumption is not true.  In such an environment, IPv4 mapped addresses
     must be passed to AF_INET6 sockets directly.  For example, if your site
     uses a SIIT translator for IPv6-to-IPv4 translation, ffttpp is unable to
     support your configuration.
