.TH EXPORT 4 .SH NAME export \- export name space on a connection .SH SYNOPSIS .B export [ .B \-a ] .I dir [ .I file ] .SH DESCRIPTION .I Export calls .IR sys-export (2) to serve the name space rooted at .I dir over a connection to a 9P (Styx) client. .I Export opens the connection on the given .IR file , or uses the standard input by default. It returns when the client closes the connection. If the .B \-a option is given, however, .I export starts an Inferno kernel process to serve the name space and returns immediately. .I Export serves the current name space without forking it; changes made to it will be visible to clients. .PP .I Export starts serving 9P immediately; it assumes that the connection has been authenticated if required. .I Export is typically called via .IR listen (1), which can authenticate the connection. .SH EXAMPLE Start a background process to serve the name space on the serial port. .IP .B "export / /dev/eia0 &" .PP Although useful when bootstrapping a system, this is unsafe unless a transport protocol is run on the connection. .SH SOURCE .B /appl/cmd/export.b .SH SEE ALSO .IR cpu (1), .IR listen (1), .IR dial (2), .IR sys-export (2), .IR intro (5)
