<h2>Description</h2>
<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 <em>none</em>, then no new log file is opened. If the
optional keyword <em>append</em> 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 class="reference internal" href="Section_start.html#start-7"><span class="std std-ref">Section 2.7</span></a> for
details.</p>
