title: how to replace : in grep output +
body: <p>if you do grep -n, the output format is like this,</p>
  
  <p>filename:line:</p>
  
  <p>Is it possible for me to tell grep to replace the first : with + so that I can copy paste the string to vim to go to that line?</p>
  
  <p>What I want is this,</p>
  
  <p>filename +line:</p>
  
  <p>Any idea how to achieve this?</p>
