<h2>Grouping commands</h2>
|
||
|
|
|
||
|
|
<p>You can group commands using either</p>
|
||
|
|
|
||
|
|
<p><strong>(</strong> <em>list</em> <strong>)</strong></p>
|
||
|
|
|
||
|
|
<p>or</p>
|
||
|
|
|
||
|
|
<p><strong>{</strong> <em>list;</em> <strong>}</strong></p>
|
||
|
|
|
||
|
|
<p>In the first case, <strong>qsh</strong> runs <em>list</em> in a
|
||
|
|
subshell environment.</p>
|
||
|
|
|
||
|
|
<p><strong>Examples</strong></p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>Group two commands in a subshell.
|
||
|
|
<pre>
|
||
|
|
( ls | grep apple )
|
||
|
|
</pre>
|
||
|
|
</li>
|
||
|
|
</ol>
