<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>Lists the files in a directory or directories. The general syntax for its use is </p>
<pre class="fragment"> ls('dirname1','dirname2',...,'dirnameN')
</pre><p> but this can also be expressed as </p>
<pre class="fragment"> ls 'dirname1' 'dirname2' ... 'dirnameN'
</pre><p> or </p>
<pre class="fragment"> ls dirname1 dirname2 ... dirnameN
</pre><p> For compatibility with some environments, the function <code>dir</code> can also be used instead of <code>ls</code>. Generally speaking, <code>dirname</code> is any string that would be accepted by the underlying OS as a valid directory name. For example, on most systems, <code>'.'</code> refers to the current directory, and <code>'..'</code> refers to the parent directory. Also, depending on the OS, it may be necessary to ``escape'' the directory seperators. In particular, if directories are seperated with the backwards-slash character <code>'\'</code>, then the path specification must use double-slashes <code>'\\'</code>. Two points worth mentioning about the <code>ls</code> function: </p>
<ul>
<li>
To get file-name completion to work at this time, you must use one of the first two forms of the command. </li>
<li>
If you want to capture the output of the <code>ls</code> command, use the <code>system</code> function instead. </li>
</ul>
<h1><a class="anchor" id="Example"></a>
Example</h1>
<p>First, we use the simplest form of the <code>ls</code> command, in which the directory name argument is given unquoted.</p>
<pre class="fragment">--> ls m*.m
</pre><p>Next, we use the ``traditional'' form of the function call, using both the parenthesis and the quoted string.</p>
<pre class="fragment">--> ls('m*.m')
</pre><p>In the third version, we use only the quoted string argument without parenthesis.</p>
<pre class="fragment">--> ls 'm*.m'
