In reply to Dan.

Each line is read twice to do the comparison if it is bigger than 20 or less than 20. What I believe this is doing is that once it found that the first condition was met it skips the second validation and goes to the next line.

1) What is the different if I simply remove $4 > 20 { print $0, "-" ;} since it's not processing at all? awk '$4 <= 20 { printf "%s\t%s\n", $0,"*"}' food_list.txt

1       Mangoes                 $3.45              5    *
5       Onions                  $1.45              15   *

2) What does it do? printf "%s\t%s\n"
