Bash sed deleting lines with words existing in another pattern
<p>I've got console output, sth like:</p>

<pre><code>SECTION/foo
SECTION/fo1
SECTION/fo3

Foo = N
Fo1 = N
Fo2 = N
Fo3 = N
Bar = Y
</code></pre>

<p>as an output, I want to have:</p>

<pre><code>Foo = N
Fo1 = N
Fo3 = N
</code></pre>

<p>Any (simple) solution?</p>

<p>Thanks in advance!</p>
