title: AWK: print every second field with different output inline-separator and different output EOF separator?
body: <p>This question is related to <a href="https://stackoverflow.com/questions/28208666/using-awk-to-print-every-second-field">using awk to print every second field</a> but I am having problems to print it neatly</p>
  
  <pre><code>$ cat printEachSecondColumnValue 
  1,11,111,1111,11111
  2,22,222,2222,22222
  3,33,333,3333,33333
  4,44,444,4444,44444
  5,55,555,5555,55555
  6,66,666,6666,66666
  $ gawk -v RS=, -v ORS="\n" '0==NR%2' printEachSecondColumnValue 
  11
  1111
  22
  2222
  33
  3333
  44
  4444
  55
  5555
  66
  6666
  $ gawk -v RS=, -v ORS="," '0==NR%2' printEachSecondColumnValue 
  11,1111,22,2222,33,3333,44,4444,55,5555,66,6666,
  </code></pre>
  
  <p>while I want to get </p>
  
  <pre><code>11,1111
  22,2222
  33,3333
  44,4444
  55,5555
  66,6666
  </code></pre>
  
  <p><strong>Can you explain the behaviour of the command piece-by-piece and how to define the inline-separator and EOF differently to get the two columns?</strong></p>
