<div class="code">
            
            <pre class='language-'><code class='language-'>xsel < /etc/fstab
</code></pre>
        </div>

To copy to the context-menu clipboard:
<div class="code">
            
            <pre class='language-'><code class='language-'>xsel --clipboard < /etc/fstab
</code></pre>
        </div>

Also Xsel can be piped to:
<div class="code">
            
            <pre class='language-'><code class='language-'>echo “a-bit-of-text” | xsel -c
cat /etc/make.conf | xsel -c
</code></pre>
        </div>

PasteTo output clipboard information to the terminal:
<div class="code">
            
            <pre class='language-'><code class='language-'>xsel --clipboard
</code></pre>
        </div>

Its just as easy to output clipboard information to a file:
<div class="code">
            
            <pre class='language-'><code class='language-'>xsel --clipboard > Baada-Boom.txt

<div class="code">
            
            <pre class='language-'><code class='language-'>xsel --clipboard >> ~/.bashrc
</code></pre>
        </div>
