title: How to installing sha1sum in MAC OS?
body: <p>Problem:
  To get the sha1sum value of a file in MAC OS i run the following command </p>
  
  <pre><code>sha1sum file_name
  </code></pre>
  
  <p>The error I got is following</p>
  
  <pre><code>perl version 5.18.2 can't run /usr/bin/sha1sum.  Try the alternative(s):
  
  /usr/bin/sha1sum5.16 (uses perl 5.16)
  
  Run "man perl" for more information about multiple version support in
  Mac OS X.
  </code></pre>
  
  <p>I tried to install <strong>textutils and coreutils</strong>, but both failed. Can anyone suggest me how I can resolve the issue ? Thanks in advance.</p>
