Print section in text file on windows

This will use awk tool.

for example input.txt:

<html>
<body>
<pre class="hello">
<p>Paragrapg</p>
<p>Another paragraph two</p>
</pre>
</body>
</html>

Run this command:

awk "/pre class/,/two/" input.txt

Output will be:

<pre class="hello">
<p>Paragrapg</p>
<p>Another paragraph two</p>

To save output in another file use:

awk "/pre class/,/two/" input.txt > output

If you want to capture full html tag you have to know that / in awk should be writed as \/ and " should be writed as a triple """:

awk "/<pre class="""hello""">/,/<\/pre>/"

and now we capture full html tag:

<html>
<body>
<pre class="hello">
<p>Paragrapg</p>
<p>Another paragraph two</p>
</pre>
</body>
</html>

Here is awk utility:
