Question

This is a very common script:

#!/bin/bash

teststr="col1 col2"

var1=`echo ${teststr} | awk '{print $1}'`
var2=`echo ${teststr} | awk '{print $2}'`

echo var1=${var1}
echo var2=${var2}

However I dont like this, especially when there are more fields to parse.
I guess there should be a better way like:

(var1,var2)=`echo ${teststr} | awk ‘{print $1 $2}’
(in my imagination)

Is that so?
Thanks for help to improve effeciency and save some CPU power.

Answer 1

This might work for you:

var=(col0 col1 col2)
echo "${var[1]}"

Will output:

col1
