title: Use the output of a cat command in execution (bash)
body: <p>Simple question I think.. but I couldnt find it with google..</p>
  
  <p>I have a file test.txt.. it contains;</p>
  
  <pre><code>blah
  blah2
  blah3
  </code></pre>
  
  <p>What I want to do is;</p>
  
  <p>cat test.txt
  and then execute;</p>
  
  <pre><code>./script blah
  ./script blah2
  ./script blah3
  </code></pre>
  
  <p>But I want to do it in one line.. What would be the best ways to do it.. ? I know using &amp;&amp; is a option.. but maybe there are better ways to pass the string?</p>
