NAME

     ftp - ARPANET file transfer program


SYNOPSIS

     ftp [-v] [-d] [-i] [-n] [-g] [-k realm] [-f] [-x] [-u]  [-t]
     [host]


DESCRIPTION

     FTP 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

     Options may be specified at the command line, or to the com-
     mand interpreter.

     -v   Verbose option forces ftp to show  all  responses  from
          the  remote  server, as well as report on data transfer
          statistics.

     -n   Restrains ftp from attempting ``auto-login'' upon  ini-
          tial  connection.   If  auto-login is enabled, ftp will
          check the .netrc (see below) file in  the  user's  home
          directory  for  an  entry  describing an account on the
          remote machine.  If no entry exists,  ftp  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.

     -u   Restrains ftp from  attempting  ``auto-authentication''
          upon  initial  connection.   If  auto-authentication is
          enabled, ftp attempts to authenticate to the FTP server
          by  sending the AUTH command, using whichever authenti-
          cation types are locally supported.  Once an  authenti-
          cation  type  is  accepted,  an authentication protocol
          will proceed by issuing  ADAT  commands.   This  option
          also disables auto-login.

     -i   Turns off interactive prompting  during  multiple  file
          transfers.

     -d   Enables debugging.

     -g   Disables file name globbing.

     -k realm
          When using Kerberos v4 authentication, gets tickets  in
          realm.

     -f   Causes credentials to be forwarded to the remote host.

     -x   Causes the client to attempt  to  negotiate  encryption
          (data   and   command  protection  levels  ``private'')
          immediately after successfully authenticating.

     -t   Enables packet tracing.


COMMANDS

     The client host with which ftp  is  to  communicate  may  be
     specified  on  the  command line.  If this is done, ftp will
     immediately attempt to establish  a  connection  to  an  FTP
     server  on  that host; otherwise, ftp will enter its command
     interpreter and await instructions from the user.  When  ftp
     is  awaiting  commands  from the user the prompt ``ftp>'' is
     provided to the user.  The following commands are recognized
     by ftp:

     ! [command] [args]]
          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.

     $ macro-name [args]
          Execute the macro macro-name that was defined with  the
          macdef  command.   Arguments  are  passed  to the macro
          unglobbed.

     account [passwd]
          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.

     append local-file [remote-file]
          Append a local file to a file on  the  remote  machine.
          If remote-file is left unspecified, the local file name
          is used in naming the remote file after  being  altered
          by  any ntrans or nmap setting.  File transfer uses the
          current settings for type, format, mode, and structure.

     ascii
          Set the file transfer type to network ASCII .  This  is
          the default type.

     bell Arrange that a bell be sounded after each file transfer
          command is completed.

     binary
          Set the file  transfer  type  to  support  binary  file
          transfer.

     bye  Terminate the FTP session with the  remote  server  and
          exit  ftp.  An end of file will also terminate the ses-
          sion and exit.

     case Toggle remote computer file name  case  mapping  during
          mget  commands.   When  case  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.

     ccc  Turn off integrity protection on the  command  channel.
          This command must be sent integrity protected, and must
          be proceeded by a successful ADAT command.  Since turn-
          ing  off  integrity  protection  potentially  allows an
          attacker to insert commands onto the  command  channel,
          some FTP servers may refuse to honor this command.

     cd remote-directory
          Change the working directory on the remote  machine  to
          remote-directory.

     cdup Change the remote  machine  working  directory  to  the
          parent of the current remote machine working directory.

     chmod mode file-name
          Change the permission modes of the  file  file-name  on
          the remote system to mode.

     clear
          Set  the  protection  level  on   data   transfers   to
          ``clear''.   If no ADAT command succeeded, then this is
          the default protection level.

     close
          Terminate the FTP session with the remote  server,  and
          return  to the command interpreter.  Any defined macros
          are erased.

     cprotect [protection-level]
          Set the protection level  on  commands  to  protection-
          level.   The  valid protection levels are ``clear'' for
          unprotected commands, ``safe'' for  commands  integrity
          protected  by  cryptographic  checksum, and ``private''
          for commands confidentiality and integrity protected by
          encryption.   If  an  ADAT  command succeeded, then the
          default command protection level is ``safe'', otherwise
          the  only  possible level is ``clear''.  If no level is
          specified, the  current  level  is  printed.   cprotect
          clear is equivalent to the ccc command.

     cr   Toggle carriage return stripping during ascii type file
          retrieval.    Records   are   denoted   by  a  carriage
          return/linefeed  sequence  during   ascii   type   file
          transfer.   When  cr  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  linefeeds;
          when  an  ascii  type transfer is made, these linefeeds
          may be distinguished from a record delimiter only  when
          cr is off.

     delete remote-file
          Delete the file remote-file on the remote machine.

     debug [debug-value]
          Toggle debugging mode.  If an optional  debug-value  is
          specified  it is used to set the debugging level.  When
          debugging is on, ftp prints each command  sent  to  the
          remote machine, preceded by the string `-->'

     dir [remote-directory] [local-file]
          Print a listing of the directory contents in the direc-
          tory,  remote-directory,  and,  optionally, placing the
          output in local-file.  If interactive prompting is  on,
          ftp  will prompt the user to verify that the last argu-
          ment is indeed the target local file for receiving  dir
          output.   If  no  directory  is  specified, the current
          working directory on the remote machine is used.  If no
          local  file  is specified, or local-file is `-', output
          comes to the terminal.

     disconnect
          A synonym for close.

     form format
          Set the file transfer form to format.  The default for-
          mat is ``file''.

     get remote-file [local-file]
          Retrieve the file remote-file 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 case, ntrans, and
          nmap settings.  The current settings  for  type,  form,
          mode,  and  structure  are  used while transferring the
          file.

     glob Toggle filename expansion for mdelete, mget, and  mput.
          If  globbing  is  turned  off  with glob, the file name
          arguments are taken literally and not expanded.   Glob-
          bing  for  mput  is done as in csh(1).  For mdelete and
          mget, each remote file name is expanded  separately  on
          the  remote  machine  and  the  lists  are  not merged.
          Expansion of a directory 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:  mget and mput 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).

     hash Toggle hash-sign (``#'') printing for each  data  block
          transferred.  The size of a data block is 1024 bytes.

     help [command]
          Print an informative message about the meaning of  com-
          mand.   If  no  argument is given, ftp prints a list of
          the known commands.

     idle [seconds]
          Set the  inactivity  timer  on  the  remote  server  to
          seconds  seconds.   If  seconds is omitted, the current
          inactivity timer is printed.

     lcd [directory]
          Change the working directory on the local machine.   If
          no directory is specified, the user's home directory is
          used.

     ls [remote-directory] [local-file]
          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 nlist.)  If
          remote-directory is left unspecified, the current work-
          ing directory is used.  If interactive prompting is on,
          ftp  will prompt the user to verify that the last argu-
          ment is indeed the target local file for  receiving  ls
          output.   If  no  local file is specified, or if local-
          file is `-', the output is sent to the terminal.

     macdefmacro-name
          Define a macro.  Subsequent lines  are  stored  as  the
          macro  macro-name;  a  null  line  (consecutive newline
          characters in a file or carriage returns from the  ter-
          minal)  terminates  macro input mode.  There is a limit
          of 16 macros and 4096 total characters in  all  defined
          macros.  Macros remain defined until a close 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 replaced 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 `$'.

     mdelete [remote-files]
          Delete remote-files on the remote machine.

     mdir remote-files local-file
          Like dir, except multiple remote files  may  be  speci-
          fied.   If interactive prompting is on, ftp will prompt
          the user to verify that the last argument is indeed the
          target local file for receiving mdir output.

     mget remote-files
          Expand the remote-files on the remote machine and do  a
          get  for  each  file  name thus produced.  See glob for
          details on  the  filename  expansion.   Resulting  file
          names will then be processed according to case, ntrans,
          and nmap 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'.

     mkdir directory-name
          Make a directory on the remote machine.

     mls remote-files local-file
          Like nlist, except multiple remote files may be  speci-
          fied,   and  the  local-file  must  be  specified.   If
          interactive prompting is on, ftp will prompt  the  user
          to  verify  that the last argument is indeed the target
          local file for receiving mls output.

     mode [mode-name]
          Set the file transfer mode to mode-name.   The  default
          mode is ``stream'' mode.

     modtime file-name
          Show the last modification time  of  the  file  on  the
          remote machine.

     mput local-files
          Expand wild cards in the list of local files  given  as
          arguments  and  do a put for each file in the resulting
          list.  See glob  for  details  of  filename  expansion.
          Resulting  file  names will then be processed according
          to ntrans and nmap settings.

     newer file-name
          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 sys-
          tem,  the  remote file is considered newer.  Otherwise,
          this command is identical to get.

     nlist [remote-directory] [local-file]
          Print a list of the files in a directory on the  remote
          machine.   If remote-directory is left unspecified, the
          current working  directory  is  used.   If  interactive
          prompting  is  on,  ftp  will prompt the user to verify
          that the last argument is indeed the target local  file
          for receiving nlist output.  If no local file is speci-
          fied, or if local-file is `-', the output  is  sent  to
          the terminal.

     nmap [inpattern outpattern]
          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 mput commands and put commands issued
          without a specified remote target filename.   If  argu-
          ments  are specified, local filenames are mapped during
          mget commands and get commands issued without a  speci-
          fied  local  target  filename.   This command is useful
          when connecting to non-UNIX remote computer  with  dif-
          ferent  file naming conventions or practices.  The map-
          ping follows the pattern set by inpattern  and  outpat-
          tern.  [Inpattern] is a template for incoming filenames
          (which may have already been processed according to the
          ntrans  and  case  settings).   Variable  templating is
          accomplished by including  the  sequences  `$1',  `$2',
          ...,  `$9'  in inpattern.  Use `\' to prevent this spe-
          cial treatment of the `$' character.  All other charac-
          ters  are  treated literally, and are used to determine
          the nmap [inpattern]  variable  values.   For  example,
          given   inpattern   $1.$2  and  the  remote  file  name
          "mydata.data", $1 would have the value "mydata", and $2
          would have the value "data".  The outpattern determines
          the resulting mapped  filename.   The  sequences  `$1',
          `$2', inpattern template.  The sequence `$0' is replace
          by the original filename.  Additionally,  the  sequence
          `[seq1,  seq2]'  is replaced by [seq1] if seq1 is not a
          null string; otherwise it is  replaced  by  seq2.   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  outpattern,  as  in  the
          example:  `nmap  $1  sed  "s/ *$//" > $1'.  Use the `\'
          character  to  prevent   special   treatment   of   the
          `$','[',']', and `,' characters.

     ntrans [inchars [outchars]]
          Set or unset the filename character translation mechan-
          ism.  If no arguments are specified, the filename char-
          acter translation mechanism is unset.  If arguments are
          specified,   characters   in   remote   filenames   are
          translated during mput commands and put commands issued
          without  a  specified remote target filename.  If argu-
          ments are specified, characters in local filenames  are
          translated during mget commands and get 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.  Characters in a filename matching a charac-
          ter in inchars  are  replaced  with  the  corresponding
          character  in outchars.  If the character's position in
          inchars is longer than  the  length  of  outchars,  the
          character is deleted from the file name.

     open host [port] [-forward]
          Establish  a  connection  to  the  specified  host  FTP
          server.   An  optional  port number may be supplied, in
          which case, ftp will attempt to contact an  FTP  server
          at  that  port.   If the auto-authenticate option is on
          (default), ftp will attempt to authenticate to the  FTP
          server  by  sending  the  AUTH command, using whichever
          authentication types which are locally supported.  Once
          an  authentication  type is accepted, an authentication
          protocol will proceed by issuing ADAT commands.  If the
          auto-login  option  is  on  (default),  ftp  will  also
          attempt to automatically log the user  in  to  the  FTP
          server  (see  below).  If the -forward option is speci-
          fied, ftp will forward a copy of  the  user's  Kerberos
          tickets to the remote host.

     passive
          Toggle passive data transfer mode.   In  passive  mode,
          the  client  initiates the data connection by listening
          on the data port.  Passive mode may  be  necessary  for
          operation  from  behind  firewalls  which do not permit
          incoming connections.

     private
          Set  the  protection  level  on   data   transfers   to
          ``private''.   Data  transmissions  are confidentiality
          and integrity protected by encryption.  If no ADAT com-
          mand   succeeded,  then  the  only  possible  level  is
          ``clear''.

     prompt
          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 mget or mput will
          transfer all files, and any  mdelete  will  delete  all
          files.

     protect [protection-level]
          Set  the  protection  level  on   data   transfers   to
          protection-level.   The  valid  protection  levels  are
          ``clear'' for unprotected data transmissions,  ``safe''
          for  data  transmissions integrity protected by crypto-
          graphic checksum, and ``private''  for  data  transmis-
          sions   confidentiality   and  integrity  protected  by
          encryption.  If no ADAT  command  succeeded,  then  the
          only  possible  level  is  ``clear''.   If  no level is
          specified, the current level is printed.   The  default
          protection level is ``clear''.

     proxy ftp-command
          Execute an ftp command on a secondary  control  connec-
          tion.   This  command allows simultaneous connection to
          two remote ftp servers for transferring  files  between
          the  two servers.  The first proxy command should be an
          open , to establish the secondary  control  connection.
          Enter  the  command "proxy ?" to see other ftp commands
          executable on the secondary connection.  The  following
          commands  behave  differently  when  prefaced by proxy:
          open will not define new macros during  the  auto-login
          process,  close  will  not erase existing macro defini-
          tions, get and mget transfer files from the host on the
          primary control connection to the host on the secondary
          control connection, and put, mput, and append  transfer
          files from the host on the secondary control connection
          to the host on the primary control  connection.   Third
          party  file  transfers  depend  upon support of the ftp
          protocol PASV command by the server  on  the  secondary
          control connection.

     put local-file [remote-file]
          Store a local file on the remote machine.   If  remote-
          file  is  left unspecified, the local file name is used
          after processing according to any ntrans or  nmap  set-
          tings  in  naming  the remote file.  File transfer uses
          the current settings for type, format, mode, and struc-
          ture.

     pwd  Print the name of the current working directory on  the
          remote machine.

     quit A synonym for bye.
     quote arg1 [arg2] [...]
          The arguments specified  are  sent,  verbatim,  to  the
          remote FTP server.

     recv remote-file [local-file]
          A synonym for get.

     reget remote-file [local-file]
          Reget acts like get, except that if  local-file  exists
          and is smaller than remote-file, local-file is presumed
          to be a partially transferred copy of  remote-file  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.

     remotehelp [command-name]
          Request  help  from  the  remote  FTP  server.   If   a
          command-name  is specified it is supplied to the server
          as well.

     remotestatus [file-name]
          With no arguments, show status of remote  machine.   If
          file-name  is  specified,  show  status of file-name on
          remote machine.

     rename [from] [to]
          Rename the file from on the remote machine, to the file
          to.

     reset
          Clear  reply  queue.   This   command   re-synchronizes
          command/reply  sequencing  with  the remote ftp server.
          Resynchronization may be necessary following  a  viola-
          tion of the ftp protocol by the remote server.

     restart marker
          Restart the immediately following get  or  put  at  the
          indicated marker.  On UNIX systems, marker is usually a
          byte offset into the file.

     rmdir directory-name
          Delete a directory on the remote machine.

     runique
          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 get or mget 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 runique  will  not  affect
          local files generated from a shell command (see below).
          The default value is off.

     safe Set the protection level on data transfers to ``safe''.
          Data  transmissions  are integrity-protected by crypto-
          graphic checksum.  If no ADAT command  succeeded,  then
          the only possible level is ``clear''.

     send local-file [remote-file]
          A synonym for put.

     sendport
          Toggle the use of PORT commands.  By default, ftp  will
          attempt  to use a PORT command when establishing a con-
          nection for each data transfer.  The use of  PORT  com-
          mands  can prevent delays when performing multiple file
          transfers.  If the PORT command fails, ftp 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.

     site arg1 [arg2] [...]
          The arguments specified  are  sent,  verbatim,  to  the
          remote FTP server as a SITE command.

     size file-name
          Return size of file-name on remote machine.

     status
          Show the current status of ftp.

     struct struct-name
          Set the file transfer  structure  to  struct-name.   By
          default ``stream'' structure is used.

     sunique
          Toggle storing of files on remote machine under  unique
          file  names.  Remote ftp server must support ftp proto-
          col STOU command for successful completion.  The remote
          server will report unique name.  Default value is off.

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

     tenex
          Set the file transfer type to that needed  to  talk  to
          TENEX machines.

     trace
          Toggle packet tracing.

     type [type-name]
          Set the file transfer type to type-name.  If no type is
          specified,  the  current  type is printed.  The default
          type is network ASCII.

     umask [newmask]
          Set the default umask on the remote server to  newmask.
          If newmask is omitted, the current umask is printed.

     user user-name [password] [account]
          Identify yourself to the remote  FTP  server.   If  the
          password  is  not specified and the server requires it,
          ftp will prompt the user for it (after disabling  local
          echo).   If  an account field is not specified, and the
          FTP server requires it, the user will be  prompted  for
          it.   If an account field is specified, an account com-
          mand 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 ftp  is  invoked
          with  ``auto-login''  disabled,  this  process  is done
          automatically on initial connection to the FTP server.

     verbose
          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  com-
          pletes,  statistics  regarding  the  efficiency  of the
          transfer are reported.  By default, verbose is on.

      ? [command]
          A synonym for help.

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


ABORTING A FILE TRANSFER

     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 ftp
     has  completed  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 unex-
     pected remote server behavior, the local ftp program must be
     killed by hand.


FILE NAMING CONVENTIONS

     Files specified as arguments to ftp commands  are  processed
     according to the following rules.

     1.   If the file name `-' is specified, stdin (for  reading)
          or stdout (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.  Ftp then forks a shell, using  popen(3)  with
          the  argument  supplied,  and  reads  from  (writes to)
          stdout (stdin).  If the shell command includes  spaces,
          the  argument  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 csh(1); c.f. the glob command.  If the ftp com-
          mand expects a single local file (.e.g.  put), only the
          first filename generated by the ``globbing''  operation
          is used.

     4.   For mget commands and  get  commands  with  unspecified
          local  file  names,  the  local  filename is the remote
          filename, which may be altered by a  case,  ntrans,  or
          nmap  setting.   The  resulting  filename  may  then be
          altered if runique is on.

     5.   For mput commands and  put  commands  with  unspecified
          remote  file  names,  the  remote filename is the local
          filename, which may be altered by a ntrans or nmap set-
          ting.   The  resulting  filename may then be altered by
          the remote server if sunique is on.


FILE TRANSFER PARAMETERS

     The FTP specification specifies many  parameters  which  may
     affect  a  file transfer.  The type may be one of ``ascii'',
     ``image'' (binary),  ``ebcdic'',  and  ``local  byte  size''
     (mostly  for PDP-10's and PDP-20's).  Ftp supports the ascii
     and image types of file transfer, plus local byte size 8 for
     tenex mode transfers.

     Ftp supports only the default values for the remaining  file
     transfer parameters:  mode, form, and struct.


THE .netrc FILE

     The .netrc file contains login and  initialization  informa-
     tion  used  by  the  auto-login  process.  It resides in the
     user's home directory.  The following tokens are recognized;
     they may be separated by spaces, tabs, or new-lines:

     machine name
          Identify a remote machine name.  The auto-login process
          searches  the  .netrc  file  for  a  machine token that
          matches the remote machine specified on the ftp command
          line  or  as an open command argument.  Once a match is
          made, the subsequent .netrc tokens are processed, stop-
          ping when the end of file is reached or another machine
          or a default token is encountered.

     default
          This is the same as machine name  except  that  default
          matches any name.  There can be only one default token,
          and it must be after all machine tokens.  This is  nor-
          mally used as:

               default login anonymous password user@site

          thereby giving the user automatic anonymous  ftp  login
          to machines not specified in .netrc.  This can be over-
          ridden by using the -n flag to disable auto-login.

     login name
          Identify a user on the remote machine.  If  this  token
          is  present,  the  auto-login  process  will initiate a
          login using the specified name.

     password string
          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 .netrc file for any user other than anonymous,  ftp
          will  abort  the  auto-login  process  if the .netrc is
          readable by anyone besides the user.

     account string
          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 addi-
          tional account password, or the auto-login process will
          initiate an ACCT command if it does not.

     macdef name
          Define a macro.  This token functions like the ftp mac-
          def  command  functions.   A  macro is defined with the
          specified name; its contents begin with the next .netrc
          line  and  continue until a null line (consecutive new-
          line characters) is encountered.  If a macro named init
          is  defined,  it  is automatically executed as the last
          step in the auto-login process.


ENVIRONMENT

     Ftp utilizes the following environment variables.

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

     SHELL
          For default shell.

HISTORY

     The ftp command appeared in 4.2BSD.


BUGS

     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 correc-
     tion may result in incorrect transfers of  binary  files  to
     and  from  4.2BSD  servers using the ascii type.  Avoid this
     problem by using the binary image type.
