I have a situation where I need to use the bash variable in awk, but it is not working.

file.txt

Fruit Good

try.sh

var="apple"
awk '{print $var " " $1 " " $2}' file.txt

Expected Output:

apple Fruit Good

Code Output:

Fruit Good Fruit Good

It seems the content of file.txt is get replaced by variable $var. Please suggest me correct approach.

`awk -v var="$var" '{print var, $1, $2}' file.txt` – anubhava Feb 14 '19 at 18:36
