title: Count number of not null rows column wise in a txt file in UNIX
body: <p>I am trying to count the number of not null rows of all column in a txt file. I am able to read not null rows in each column individually but I am trying to loop them all together. <code>awk - F "|" '$1!=""{N++} print N'</code></p>
  
  <p>Here is a look at my data</p>
  
  <p>A | B | C | D | E</p>
  
  <p>1 | 2 | 0 | 8 |</p>
  
  <p>5 | 3 | 6 |    | 4</p>
  
  <p>|    | 8 |    | </p>
  
  <p>| 7 | 8 |    | </p>
  
  <p>8 | 9 | 2 |    | 4</p>
  
  <p>I want the result to be like :
  Column A: 3
  Column B: 4
  Column C: 5
  Column D: 1
  Column E: 2</p>
