How to `wget` a list of URLs in a text file? : <p>Let's say I have a text file of hundreds of URLs in one location, e.g.</p>

<pre><code>http://url/file_to_download1.gz
http://url/file_to_download2.gz
http://url/file_to_download3.gz
http://url/file_to_download4.gz
http://url/file_to_download5.gz
....
</code></pre>

<p>What is the correct way to download each of these files with <code>wget</code>? I suspect there's a command like <code>wget -flag -flag text_file.txt</code></p>
