title: How do I obtain the GNU gsed command in Solaris Unix
body: <p>Im trying to use the <strong>gsed -n '1~4p'</strong> command to only print that line which appears every 8 lines, but apparently it can only be done with a GNU sed, but It doesn't seem that I have one, How would I obtain this?</p>
  
  <p>I have been using <strong>sed -n '1,${p;n;n;n;}'</strong> , Im not sure if it does the same thing but it doesnt perform print my expected output.</p>
  
  <p>Thanks!</p>
