       <para>The <literal>lst</literal> utility uses the <literal>LST_SESSION</literal> environmental variable to identify the session locally on the self-test console node. This should be a numeric value that uniquely identifies all session processes on the node. It is convenient to set this to the process ID of the shell both for interactive use and in shell scripts. Almost all <literal>lst</literal> commands require <literal>LST_SESSION</literal> to be set.</para>
