How to put an argument vector with an argument containing spaces in a bash variable

Question

How can I store an argument vector with an argument containing spaces in a bash variable?

For example, I want 2.sh to print b c

1.sh

#!/bin/bash

ARGV='a "b c"'
./2.sh $ARGV

2.sh

#!/bin/bash

echo $2

Answer 1

You should use an array instead of a string:

args=("a" "b c")
./2.sh "${args[@]}"

When the array expansion is quoted, each element of the array is properly expanded.
