<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>

    <tt><font size=+1>import</font></tt> [ <tt><font size=+1>&#8722;df</font></tt> ] [ <tt><font size=+1>&#8722;n</font></tt> <i>ns</i> ] [ <tt><font size=+1>&#8722;p</font></tt> <i>prog</i> ] [ <tt><font size=+1>&#8722;s</font></tt> <i>service</i> ] <i>system<br>
    </i>
</table>
<p><font size=+1><b>DESCRIPTION     </b></font><br>

<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>

    <i>Import</i> presents the 9P service <i>service</i> (default <tt><font size=+1>plumb</font></tt>) running
    on <i>system</i> as a service on the local system, in the current name
    space. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The <tt><font size=+1>&#8722;n</font></tt> option sets the remote name space directory where <i>import</i>
    should expect to find <i>service</i>. If it is not specified, <i>import</i>
    uses name of the local system&#8217;s name space directory. (Since name
    space directories are conventionally inside <tt><font size=+1>/tmp</font></tt>, the path have
    different meanings on the two systems.) 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <i>Import</i> connects to <i>system</i> using <a href="../man1/ssh.html"><i>ssh</i>(1)</a>. It invokes <i>import</i> on the
    remote system to carry out the remote side of the protocol. The
    <tt><font size=+1>&#8722;p</font></tt> option specifies the path to <i>import</i> on the remote system, in
    case it is not in the system search path. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The <tt><font size=+1>&#8722;d</font></tt> option turns on debugging. The <tt><font size=+1>&#8722;f</font></tt> option keeps <i>import</i> from
    forking itself into the background, also useful for debugging.<br>
    
</table>
<p><font size=+1><b>EXAMPLE     </b></font><br>

<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>

    Suppose you run <tt><font size=+1>sam &#8722;r</font></tt> to the CPU server <i>anna</i>. <i>Sam</i> wants to talk
    to a plumber on the local terminal, but the file names will refer
    to files on <i>anna</i>. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    To fix this problem, create a new name space directory and start
    a new plumber on <i>anna</i>:<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>

        <tt><font size=+1>remotens=/tmp/ns.`whoami`.on.`hostname`<br>
        ssh anna mkdir $remotens<br>
        ssh anna NAMESPACE=$remotens plumber<br>
        </font></tt>Now import that plumber to the local name space before starting
        <i>sam</i> and <i>9term</i>:<br>
        <tt><font size=+1>NAMESPACE=/tmp/ns.anna<br>
        mkdir $NAMESPACE<br>
        import &#8722;n $remotens &#8722;s plumb anna<br>
        sam &amp;<br>
        9term ssh anna &amp;<br>
        </font></tt>
