Replace a word after a particular word in a file
Hi,

I want to replace a word in a file which occurs after a particular word.

For example :
Code:
 
$cat file.txt
CASE
   WHEN
      AND c1 = 'I'
       AND c2= '2'
        THEN  1
   WHEN
      AND c1= 'I'
       AND c2= '0'
        THEN  2

So in this example i want to replace the AND which occurs after WHEN.

SO the required output :
Code:
 
$cat file.txt
CASE
   WHEN
             c1 = 'I'
       AND c2= '2'
       THEN  1
   WHEN
             c1= 'I'
       AND c2= '0'
       THEN  2
