title: grep excluding first char
body: <p>How do I find a line where a pattern is in middle of line. i.e. in the following example. I want to only get 8th line but exclude 1st and 5th line grepping "@"</p>
  
  <p>I know i would use <code>grep "^@"</code> to find only in first character but how to exclude it?</p>
