NAME
     xtp - file transfer program

SYNOPSIS
     xtp [ -options ... ] <uniform resource locator>

DESCRIPTION
     Xtp is a utility for retrieving, listing, or printing files
     from a remote network site, or sending files to a remote
     network site.  xtp performs most of the same functions as
     the ftp(1) program, but does not require any interactive
     commands.  You simply specify the file transfer task on the
     command line and xtp performs the task automatically.

EXAMPLES
     To retrieve the file bird.jpg in directory images from  host
     wizard.dupont.com, use:

          xtp ftp://wizard.dupont.com/images/bird.jpg

     To retrieve all the files from directory images as user
     magick from host wizard.dupont.com, use:

          xtp -retrieve ftp://magick@wizard.dupont.com/images/

     You will be prompted for a password.

     To retrieve all the files from directory images as user
     magick and password magick from host wizard.dupont.com, use:

          xtp -retrieve
     ftp://magick:magick@wizard.dupont.com/images/

OPTIONS
     -account password
          Supply a supplemental password required by a remote
          system for access to resources.

     -binary
          retrieve files as binary.  This is the default.  Use
          +binary to retrieve files as text.

     -directory
          list the names of files and their attributes that match
          the filename component of the uniform resource locator.
          The filename component is processed as a regular
          expression.

     -exclude expression
          exclude files that match the regular expression.

          This option applies to the -directory, -print, or
          -retrieve options.

     -file name
          store the file with this name.

          Refer to the -get and -put option for more details.

     -get get files that match the filename component of the
          uniform resource locator.  The filename component is
          expanded by passing it to csh(1).

          This option is equivalent to using the ftp get command.
          However, if the filename contains globbing characters
          this option is equivalent to the ftp mget command.
          Without globbing characters, you can store the file
          locally with a different name by using the -file
          option.

     -port number
          If no port number is specified, xtp attempts to contact
          a FTP server at the default port.  Otherwise, the
          specified port number is used.

     -proxy hostname
          access the remote host via a proxy ftpd client running
          on this host.

          The default value of this option can be set with the
          environment variable xtp_proxy.  See ENVIRONMENT for
          more details.  Use +proxy to prevent proxy connections.

     -print
          print files that match the filename component of the
          uniform resource locator.  The filename component is
          processed as a regular expression.

     -prune
          process files in the remote directory specified by the
          directory component of the uniform resource locator.
          Do not recursively search for files.

     -put put files that match the filename component of the
          uniform resource locator.  The filename component is
          expanded by passing it to csh(1).

          This option is equivalent to using the ftp put command.
          However, if the filename contains globbing characters
          this option is equivalent to the ftp mput command.
          Without globbing characters, you can store the file
          remotely with a different name by using the -file
          option.

     -retrieve
          retrieve files that match the filename component of the
          uniform resource locator.  The filename component is
          processed as a regular expression.

          Retrieved files are stored on your local host directory
          as the full name of the retrieved file.  For example,
          if the retrieved file is named documents/xtp.man on the
          remote FTP server, it will appear in your remote
          directory as documents/xtp.man.

     -timeout seconds
          specifies the maximum seconds to complete your remote
          FTP server request.  If this time expires, the program
          terminates.  The program also terminates if one tenth
          of this value is exceeded while logging onto the remote
          FTP server.

     -type name
          identify the remote system type: UNIX, VMS, or other.

          The system type is determined automatically, however,
          you can override the system type with this option.

     -verbose
          show all responses from the remote server.

     If only the program name is specified on the command line,
     the program command syntax and options are listed.

     If neither -directory, -print, -put, or -retrieve are
     specified on the command line, the file or files specified
     by the uniform resource locator is retrieved from the remote
     network host (as if -get was specified).

     <uniform resource locator> has the format:

         protocol://host/[directory/[filename]]

     where protocol is ftp and host is
     [user[:password]]@hostname.  User defaults to anonymous and
     password defaults to host.domain.  Note that
     directory/[filename] is interpreted relative to the home
     directory for user, thus an absolute pathname must be
     specified with the leading /:

         ftp://host//tmp/anyfile

     As an extension, the filename part of the locator is
     expanded by the shell for options -get or -put, otherwise it
     is processed as a regular expression.  For convenience, the
     protocol component of the uniform resource locator (ftp://)
     may be omitted.

     Xtp retrieves files from the remote directory for -get and
     puts files in the remote directory for -put.  Otherwise, xtp
     looks for a file of the form ls-lls-l([Rt])+([Rt])* and
     assumes it contains a recursive directory listing.  If none
     is found, xtp recursively descends the directory hierarchy
     from the remote directory.  Some remote hosts may have
     thousands of files causing a significant delay satisfying
     your request.  This can be wasteful if the files you are
     interested in reside in a known directory.  You can reduce
     the searching required by specifying <remote directory> on
     the command line.  This limits the filename search to the
     specified directory and any of its subdirectories.
     Alternatively, -prune restricts the search to the remote
     directory only.

REGULAR EXPRESSIONS
     A regular expression is zero or more branches, separated by
     |.  It matches anything that matches one of the branches.

     A branch is zero or more pieces, concatenated.  It matches a
     match for the first, followed by a match for the second,
     etc.

     A piece is an atom possibly followed by *, +, or ?.  An atom
     followed by * matches a sequence of 0 or more matches of the
     atom.  An atom followed by + matches a sequence of 1 or more
     matches of the atom.  An atom followed by ? matches a match
     of the atom, or the null pattern.

     An atom is a regular expression in parentheses (matching a
     match for the regular expression), a range (see below), .
     (matching any single character), ^ (matching the null
     pattern at the beginning of the input pattern), $ (matching
     the null pattern at the end of the input pattern), a '
     followed by a single character (matching that character), or
     a single character with no other significance (matching that
     character).

     A range is a sequence of characters enclosed in [].  It
     normally matches any single character from the sequence.  If
     the sequence begins with ^, it matches any single character
     not from the rest of the sequence.  If two characters in the
     sequence are separated by -, this is shorthand for the full
     list of ASCII characters between them (e.g.  [0-9] matches
     any decimal digit). To include a literal ] in the sequence,
     make it the first character (following a possible ^).  To
     include a literal -, make it the first or last character.
