title: Grep unknown number of spaces (linux)
body: <p>Suppose you have a file named abc.txt - the file contains 2 (or generally more) lines:</p>
  
  <pre><code>word  -c           (09:35:20)
  word     -c        (09:38:49)
  </code></pre>
  
  <p>If you run the command <code>$ grep "word  -c" abc.txt</code> you get only the 1st line, because the number of spaces between 1 and -c does not match the 2nd line.  Is there a way to fix this problem?</p>
  
  <p>You cannot use <code>grep'word1|word2' /path/to/file</code> as the spaces between word and -c vary.</p>
