	</P>
	<P>This command closes the current LAMMPS log file, opens a new file with
	the specified name, and begins logging information to it. If the
	specified file name is <I>none</I>, then no new log file is opened. If the
	optional keyword <I>append</I> is specified, then output will be appended
	to an existing log file, instead of overwriting it.
	</P>
	<P>If multiple processor partitions are being used, the file name should
	be a variable, so that different processors do not attempt to write to
	the same log file.
	</P>
	<P>The file "log.lammps" is the default log file for a LAMMPS run. The
	name of the initial log file can also be set by the command-line
	switch -log. See <A HREF = "Section_start.html#start_7">Section_start 6</A> for
	details.
