title: Grep using patterns in file
body: <p>Im trying to use the patterns in a file to grep another one but there's no output. I know they are there because I can see and use gedit "Find". Here's what I'm doing</p>
  
  <pre><code>grep -f scored.txt index.txt
  </code></pre>
  
  <p>And heres a sample of both files:</p>
  
  <p>score.txt </p>
  
  <pre><code>11gs
  
  1amw
  
  1alw
  
  1a8i
  
  1a0q
  </code></pre>
  
  <p>index.txt</p>
  
  <pre><code>11gs,2.30,1999,5.82,Ki=1.5uM,11gs.pdf,(GTT-EAA)
  1a0q,2.30,1999,7.57,Ki=27nM,1a0q.pdf,(HEP)
  1a8i,1.78,1998,5.52,Ki=3.0uM,1a8i.pdf,(GLS)
  1alw,2.03,1998,6.52,Ki=0.3uM,1alw.pdf,(ISA)
  1amw,1.85,1998,4.54,Kd=29uM,1a4h.pdf,(ADP)
  </code></pre>
  
  <p>I'm edditing here because this example case WORKS. However, when I try with the full files I still don't get any output</p>
