+		<p>And we can do the same also with a remote <code>fstab</code> or <code>mtab</code>; just by adding <code>ssh</code> to the pipeline:</p>
+
+		<m:pre jazyk="bash"><![CDATA[ssh example.com cat /etc/mtab | relpipe-in-fstab | relpipe-out-tabular]]></m:pre>
+		
+		<p>
+			The <code>cat</code> runs remotely. The <code>relpipe-in-fstab</code> and <code>relpipe-out-tabular</code> run on our machine.
+		</p>
+		
+		<p>
+			n.b. the <code>relpipe-in-fstab</code> reads the <code>/etc/fstab</code> if executed on TTY. Otherwise, it reads the STDIN.
