title: Grepping a huge file (80GB) any way to speed it up?
body: <pre><code> grep -i -A 5 -B 5 'db_pd.Clients'  eightygigsfile.sql
  </code></pre>
  
  <p>This has been running for an hour on a fairly powerful linux server which is otherwise not overloaded.
  Any alternative to grep? Anything about my syntax that can be improved, (egrep,fgrep better?) </p>
  
  <p>The file is actually in a directory which is shared with a mount to another server but the actual diskspace is local so that shouldn't make any difference? </p>
  
  <p>the grep is grabbing up to 93% CPU</p>
