How if-else Works Without Operators In AWK

In this article we will see when if block is true or false in without operator scenario. Means none of the following is used.
-eq/-ne/-lt/-gt/=/==/!=

echo "" | awk 'BEGIN{V_Count=0}
   { if (V_Count)
     {
         print "TRUE"
     }
     else
     {
         print "FALSE"
     }
   }'

Output: In above scenario, we have initialized a variable V_Count and assigned the value as 0. if inside awk command considered 0 as FALSE hence displayed FALSE on terminal.

$ echo "" | awk 'BEGIN{V_Count=1}
   { if (V_Count)
     {
         print "TRUE"
     }
     else
     {
         print "FALSE"
     }
   }'

[OR]

$ echo "" | awk 'BEGIN{V_Count=2}
   { if (V_Count) 
     {
         print "TRUE"
     } 
     else
     {
         print "FALSE"
     }
   }'

Output: In above scenario, we have initialized a variable V_Count and assigned the value as 1 and 2 in next example. if inside awk command considered non-zero value as TRUE hence displayed TRUE on terminal for both the cases.

Note: This is very important concept of awk command and is used extensively. Keep the concept handy for complex code understanding.
