+ ffttpp --uu _u_r_l file [_._._.]
+ 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-
+ --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-
+ --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-
+ 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_-
+ 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
+ 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
+ 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-
+ 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-
+ 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
+ iimmaaggee A synonym for bbiinnaarryy.
+ 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.
+ lleessss _f_i_l_e A synonym for ppaaggee.
+ llppaaggee _l_o_c_a_l_-_f_i_l_e
+ Display _l_o_c_a_l_-_f_i_l_e with the program specified by the sseett
+ ppaaggeerr option.
+ llppwwdd Print the working directory on the local machine.
+ llss [_r_e_m_o_t_e_-_p_a_t_h [_l_o_c_a_l_-_f_i_l_e]]
+ A synonym for ddiirr.
+ 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-
+ 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 ...'.
+ 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 (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-
+ mmoorree _f_i_l_e A synonym for ppaaggee.
+ mmppuutt _l_o_c_a_l_-_f_i_l_e_s
+ 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
+ As per mmggeett, but performs a rreeggeett instead of ggeett.
+ mmsseenndd _l_o_c_a_l_-_f_i_l_e_s
+ A synonym for mmppuutt.
+ 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
+ nnlliisstt [_r_e_m_o_t_e_-_p_a_t_h [_l_o_c_a_l_-_f_i_l_e]]
+ A synonym for llss.
+ 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
+ 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.
+ [_I_n_p_a_t_t_e_r_n] is a template for incoming filenames (which may
+ have already been processed according to the nnttrraannss and ccaassee
+ 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
+ sseett ppaaggeerr option.
+ 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.)
+ ppddiirr [_r_e_m_o_t_e_-_p_a_t_h]
+ Perform ddiirr [_r_e_m_o_t_e_-_p_a_t_h], and display the result with the
+ program specified by the sseett ppaaggeerr option.
+ ppllss [_r_e_m_o_t_e_-_p_a_t_h]
+ Perform llss [_r_e_m_o_t_e_-_p_a_t_h], and display the result with the
+ program specified by the sseett ppaaggeerr option.
+ ppmmllssdd [_r_e_m_o_t_e_-_p_a_t_h]
+ Perform mmllssdd [_r_e_m_o_t_e_-_p_a_t_h], and display the result with the
+ program specified by the sseett ppaaggeerr option.
+ pprreesseerrvvee Toggle preservation of modification times on retrieved files.
+ 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
+ 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
+ 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).

+ 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.

+ 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.

+ 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 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
+ FTP server are displayed to the user. In addition, if ver-
+ bose is on, when a file transfer completes, statistics re-

+ 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.
+ 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:
+ ``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.
+ 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
+ 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.
+ 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
+ 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
+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.

+ 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-

+ 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
+ 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).
+ 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.
