title: grep command on multiple lines (not multiline grep)
body: <p>Trying to figure out how to write a command across multiple lines because the real one is way to long for a prompt (4200 chars), so I tried this example:</p>
  
  <p>Made a test file that contained the following 3 lines:</p>
  
  <p><code>some thing</code><br>
  <code>some</code><br>
  <code>thing</code></p>
  
  <p>When I do this grep:<br><code>grep "some thing" test</code></p>
  
  <p>I get the expected result of:<br><code>some thing</code></p>
  
  <p>But when I do this grep: <br><code>grep "some \</code><br>
  <code>thing" test</code></p>
  
  <p>I get the unexpected result of:<br>
  <code>some thing</code><br>
  <code>thing</code></p>
  
  <p>Almost as if it ran the grep twice, once for "some " and once for "thing".  Is there any way to properly use the <code>\</code> to combine the 2 to where the result is like the first grep?</p>
