<p>GraphicsMagick provides a powerful command line utility <cite>gm</cite>, 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
commands via a single executable command-line program; for example, to
use the "convert" sub-command, type <span class="docutils literal">gm convert ...</span>. The available
commands are as follows:</p>
<table>
