or

<pre>
bazel [&lt;startup options&gt;] &lt;command&gt; [&lt;args&gt;] -- [&lt;target patterns&gt;]
</pre>

See the <a href="guide.html#target-patterns">User's Guide</a> for the
target patterns syntax.

<h2>Option Syntax</h2>

<p>
Options can be passed to Bazel in different ways. Options that require a value
can be passed with either an equals sign or a space:
<pre>
--&lt;option&gt;=&lt;value&gt;
--&lt;option&gt; &lt;value&gt;
</pre>
Some options have a single character short form; in that case, the short form
has to be passed with a single dash and a space.
<pre>
-&lt;short_form&gt; &lt;value&gt;
</pre>
</p>

<p>
Boolean options can be enabled as follows:
<pre>
--&lt;option&gt;
--&lt;option&gt;=[true|yes|1]
</pre>

and disabled as follows:
<pre>
--no&lt;option&gt;
--&lt;option&gt;=[false|no|0]
</pre>
</p>

<p>
Tristate options are usually set to automatic by default, and can be
force-enabled as follows:
<pre>
--&lt;option&gt;=[true|yes|1]
</pre>
or force-disabled as follows:
<pre>
--no&lt;option&gt;
--&lt;option&gt;=[false|no|0]
</pre>
</p>
