<h2>Description<a class="headerlink" href="#description" title="Link to this heading"></a></h2>
<p>This command causes LAMMPS to exit, after shutting down all output
cleanly.</p>
<p>It can be used as a debug statement in an input script, to terminate
the script at some intermediate point.</p>
<p>It can also be used as an invoked command inside the “then” or “else”
portion of an <a class="reference internal" href="if.html"><span class="doc">if</span></a> command.</p>
<p>The optional status argument is an integer which signals the return
status to a program calling LAMMPS. A return status of 0 usually
indicates success. A status != 0 is failure, where the specified
value can be used to distinguish the kind of error, e.g. where in the
input script the quit was invoked. If not specified, a status of 0 is
returned.</p>
