   environment variable).
   If
   .Ar host
   is given,
   then gate-ftp mode will be enabled, and the gate-ftp server will be set to
   .Ar host .
   If
   .Ar port

   gate-ftp server.
   .It Ic get Ar remote-file Op Ar local-file
   Retrieve the

   are taken literally and not expanded.
   Globbing for
   .Ic mput
   is done as in
   .Xr csh 1 .
   For
   .Ic mdelete
   and
   .Ic 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
   .Dq mls remote-files - .
   Note:
   .Ic mget
   and
   .Ic mput
   are not meant to transfer
   entire directory subtrees of files.
   That can be done by

   There is a limit of 16 macros and 4096 total characters in all
   defined macros.
   Macro names can be a maximum of 8 characters.
   Macros are only applicable to the current session they are
   defined in (or if defined outside a session, to the session
   invoked with the next
   .Ic open

   command is executed.
   To invoke a macro,
   use the

   The macro processor interprets
   .Ql $

   with different file naming conventions or practices.
   .Pp
   The mapping follows the pattern set by
   .Ar inpattern
   and
   .Ar outpattern .
   .Ar inpattern
   is a template for incoming filenames (which may have already been
   processed according to the
   .Ic ntrans
   and
   .Ic case
   settings).
   Variable templating is accomplished by including the
   sequences
   .Ql $1 ,
   .Ql $2 ,
   \&...,
   .Ql $9
   in
   .Ar inpattern .
   Use
   .Ql \e
   to prevent this special treatment of the
   .Ql $
   character.
   All other characters are treated literally, and are used to determine the
   .Ic nmap
   .Ar inpattern
   variable values.
   .Pp
   For example, given
   .Ar inpattern
   $1.$2 and the remote file name "mydata.data", $1 would have the value
   "mydata", and $2 would have the value "data".
   The
   .Ar outpattern
   determines the resulting mapped filename.
   The sequences
   .Ql $1 ,
   .Ql $2 ,
   \&...,
   .Ql $9
   are replaced by any value resulting from the
   .Ar inpattern
   template.
   The sequence
   .Ql $0
   is replaced by the original filename.
   Additionally, the sequence
   .Sq Op Ar seq1 , Ar seq2
   is replaced by
   .Ar seq1
   if
   .Ar seq1
   is not a null string; otherwise it is replaced by
   .Ar seq2 .
   For example:
   .Pp
   .Dl nmap $1.$2.$3 [$1,$2].[$2,file]
   .Pp
   This command would yield the output filename
   .Pa myfile.data
   for input filenames
   .Pa myfile.data
   and
   .Pa myfile.data.old ;
   .Pa myfile.file
   for the input filename
   .Pa myfile ;
   and
   .Pa myfile.myfile
   for the input filename
   .Pa .myfile .
   Spaces may be included in
   .Ar outpattern
   by quoting them,
   as in the following example:
   .Bd -literal -offset indent
   nmap $1.$2 "$1 $2"
   .Ed
   .Pp
   Use the
   .Ql \e
   character to prevent special treatment
   of the
   .Ql $ ,
   .Ql \&[ ,
   .Ql \&] ,
   and
   .Ql \&,
   characters.
   .It Ic ntrans Op Ar inchars Op Ar outchars
   Set or unset the filename character translation mechanism.
   If no arguments are specified, the filename character
   translation mechanism is unset.
   If arguments are specified, characters in
   remote filenames are translated during
   .Ic mput
   commands and
   .Ic put
   commands issued without a specified remote target filename.
   If arguments are specified, characters in
   local filenames are translated during
   .Ic mget
   commands and
   .Ic get
   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
   .Ar inchars
   are replaced with the corresponding character in
   .Ar outchars .
   If the character's position in
   .Ar inchars
   is longer than the length of
   .Ar outchars ,
   the character is deleted from the file name.

   .Sh 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 an FTP protocol
   .Dv 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
   .Dv ABOR
   processing.
   If the remote server does not support the
   .Dv ABOR
   command, an
   .Ql ftp\*(Gt
   prompt will not appear until the remote server has completed
   sending the requested file.
   .Pp
   The terminal interrupt key sequence will be ignored when
   .Nm
   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
   violations of the FTP protocol.
   If the delay results from unexpected remote server behavior, the local
   .Nm
   program must be killed by hand.
   .Sh FILE NAMING CONVENTIONS
   Files specified as arguments to
   .Nm
   commands are processed according to the following rules.
   .Bl -enum
   .It
   If
   .Sq -
   is specified as a local file name, the standard input (for reading)
   or standard output (for writing)
   is used.
   .It
   If the first character of a local file name is
   .Sq \&| ,
   the
   remainder of the argument is interpreted as a shell command.
   .Nm
   then forks a shell, using
   .Xr popen 3
   with the argument supplied, and reads (writes) from the standard output
   (standard input).
   If the shell command includes spaces, the argument
   must be quoted; e.g.,
   .Qq ls -lt .
   A particularly
   useful example of this mechanism is:
   .Qq ls \&. |more .
   .It
   Failing the above checks, if
   .Dq globbing
   is enabled,
   local file names are expanded
   according to the rules used in the
   .Xr csh 1
   .Ic glob
   command.
   If the
   .Nm
   command expects a single local file (e.g.,
   .Ic put ) ,
   only the first filename generated by the
   .Dq globbing
   operation is used.
   .It
   For
   .Ic mget
   commands and
   .Ic get
   commands with unspecified local file names, the local filename is
   the remote filename, which may be altered by a
   .Ic case ,
   .Ic ntrans ,
   or
   .Ic nmap
   setting.
   The resulting filename may then be altered if
   .Ic runique

   commands and
   .Ic put
   commands with unspecified remote file names, the remote filename is
   the local filename, which may be altered by a
   .Ic ntrans
   or
   .Ic nmap
   setting.
   The resulting filename may then be altered by the remote server if
   .Ic sunique
   is on.
   .El
   .Sh FILE TRANSFER PARAMETERS
   The FTP specification specifies many parameters which may
   affect a file transfer.
   The
   .Ic type
   may be one of
   .Dq ascii ,
   .Dq binary ,
   or
   .Dq image .
   .Nm
   supports the ASCII and image types of file transfer.
   .Pp
   .Nm
   supports only the default values for the remaining
   file transfer parameters:
   .Ic mode ,
   .Ic form ,
   and
   .Ic struct .
   .Sh THE .netrc FILE
   The
   .Pa .netrc
   file contains login and initialization information
   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:
   .Bl -tag -width password
   .It Ic machine Ar name
   Identify a remote machine
   .Ar name .
   The auto-login process searches the
   .Pa .netrc
   file for a
   .Ic machine
   token that matches the remote machine specified on the
   .Nm
   command line or as an
   .Ic open
   command argument.
   Once a match is made, the subsequent
   .Pa .netrc
   tokens are processed,
   stopping when the end of file is reached or another
   .Ic machine
   or a
   .Ic default
   token is encountered.
   .It Ic default
   This is the same as
   .Ic machine
   .Ar name
   except that
   .Ic default
   matches any name.
   There can be only one
   .Ic default
   token, and it must be after all
   .Ic machine
   tokens.
   This is normally used as:
   .Pp
   .Dl default login anonymous password user@site
   .Pp
   thereby giving the user
   .Ar automatic
   anonymous FTP login to
   machines not specified in
   .Pa .netrc .
   This can be overridden
   by using the
   .Fl n
   flag to disable auto-login.
   .It Ic login Ar name
   Identify a user on the remote machine.
   If this token is present, the auto-login process will initiate
   a login using the specified
   .Ar name .
   .It Ic password Ar 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
   .Pa .netrc
   file for any user other
   than
   .Ar anonymous ,
   .Nm
   will abort the auto-login process if the
   .Pa .netrc
   is readable by
   anyone besides the user.
   .It Ic account Ar 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 additional
   account password, or the auto-login process will initiate an
   .Dv ACCT
   command if it does not.
   .It Ic macdef Ar name
   Define a macro.
   This token functions like the
   .Nm
   .Ic macdef
   command functions.
   A macro is defined with the specified name; its contents begin with the
   next
   .Pa .netrc
   line and continue until a null line (consecutive new-line
   characters) is encountered.
   Like the other tokens in the
   .Pa .netrc
   file, a
   .Ic macdef
   is applicable only to the
   .Ic machine
   definition preceding it.
   A
   .Ic macdef
   entry cannot be utilized by multiple
   .Ic machine
   definitions; rather, it must be defined following each
   .Ic machine
   it is intended to be used with.
   If a macro named
   .Ic init
   is defined, it is automatically executed as the last step in the
   auto-login process.
   .El
   .Sh COMMAND LINE EDITING
   .Nm
   supports interactive command line editing, via the
   .Xr editline 3
   library.
   It is enabled with the
   .Ic edit
   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.
   .Pp
   The
   .Xr editline 3
   library is configured with a
   .Pa .editrc
   file \- refer to
   .Xr editrc 5
   for more information.
   .Pp
   An extra key binding is available to
   .Nm
   to provide context sensitive command and filename completion
   (including remote file completion).
   To use this, bind a key to the
   .Xr editline 3
   command
   .Ic ftp-complete .
   By default, this is bound to the TAB key.
 .Sh ENVIRONMENT  .Sh ENVIRONMENT
