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 connection. 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.
