     EXPORT(4)                                               EXPORT(4)

     NAME
          export - export name space on a connection

     SYNOPSIS
          export [ -a ] dir [ file ]

     DESCRIPTION
          Export calls sys-export(2) to serve the name space rooted at
          dir over a connection to a 9P (Styx) client.  Export opens
          the connection on the given file, or uses the standard input
          by default.  It returns when the client closes the connec-
          tion.  If the -a option is given, however, export starts an
          Inferno kernel process to serve the name space and returns
          immediately.  Export serves the current name space without
          forking it; changes made to it will be visible to clients.

          Export starts serving 9P immediately; it assumes that the
          connection has been authenticated if required.  Export is
          typically called via listen(1), which can authenticate the
          connection.

     EXAMPLE
          Start a background process to serve the name space on the
          serial port.

               export / /dev/eia0 &

          Although useful when bootstrapping a system, this is unsafe
          unless a transport protocol is run on the connection.
