awk for different scenarios

Question

I am currently trying to work up a solution that generates strings based on the input.

When I execute the function

cat text | awk '{printf("%s global\n", $1);}'

in which text is

0_0_0_0_1_1_1_1 NO NO NO NO YES YES YES YES

and the output is

0_0_0_0_1_1_1_1 global

which is correct, but in some cases the text can be

K_0_0_0_0_1_1_1_1 NO NO NO NO YES YES YES YES

in which case the following command, would not work, as the output should be

K_0_0_0_0_1_1_1_1 Kai

how do i make awk know when it should output Kai or global?

Answer 1

You can use conditional print:

awk '{print $1, ($1 ~ /^K_/ ? "Kai" : "global")}' file

0_0_0_0_1_1_1_1 global
K_0_0_0_0_1_1_1_1 Kai
