EXPORT(4) EXPORT(4) NAME export, 9export - export name space on a connection SYNOPSIS export [ -a ] [ -n ] dir [ file ] 9export dir DESCRIPTION Export calls Sys->export (see sys-dial(2)) to serve a name space rooted at dir over a connection to a 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. Normally, export forks the current name space, and makes dir the root of its copy. Changes subsequently made to the cur- rent name space will not be visible to clients of export. If the -n option is given, however, and dir is the root (`/'), export serves the current name space without forking it; changes made to it will be visible to clients. Export starts serving Styx immediately; it assumes that the connection has been authenticated if required. 9export serves the name space rooted at dir over standard input and output to a 9P client; 9P is Plan 9's variant of Styx, defined in section 5 of the Plan 9 Manual. No Plan 9 authentication is performed, and the Tclwalk message is unimplemented. 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.
