<p>GraphicsMagick provides a powerful command line utility which may be used
to access all GraphicsMagick functions. Gm uses a consistent set of
options (<a class="reference external" href="GraphicsMagick.html">see options documentation</a>).
GraphicsMagick provides access to major command modes via a single
executable command-line program called <tt class="docutils literal"><span class="pre">gm</span></tt>; for example, to use the
"convert" mode, type <tt class="docutils literal"><span class="pre">gm</span> <span class="pre">convert</span> <span class="pre">...</span></tt>. The available command modes and
links to their documentation are shown in the following table:</p>
<table border="1" class="docutils">
<colgroup>
<col width="17%" />
<col width="83%" />
</colgroup>
<thead valign="bottom">
<tr><th class="head">GM Command Mode</th>

</table>
<p>The <tt class="docutils literal"><span class="pre">gm</span></tt> utility makes it easy to perform complex image processing
operations using a single command. It may be invoked from scripts, or
from other programs in order to automate the processing of thousands of
images.</p>
