Question

I am using book “The AWK programming langauge” by Aho ,Kernighan ..
On page 20 they have given a program which doesn’t work on my system.

emp.data is

Beth 4.00 0
Dan 3.75  0
Kathy 4.00 10
Mark 5.00 20
Mary  5.50 22
Susie  4.25 18

program they have given is

awk '{ printf("%6.2f  %s\n" , $2*$3, $0) }' emp.data | sort

and the output they have given is

But my output is

0.00  Beth 4.00 0
  0.00  Dan 3.75  0
100.00  Mark 5.00 20
121.00  Mary  5.50 22
 40.00  Kathy 4.00 10
 76.50  Susie  4.25 18

so whats happening ?

Answer 1

Try sort -n at the end, to do a numerical sort. The default sort would put 10 before 2.
