Quoting in a function results in error

Question

How should I write the command variable to get the expected behavior?

#!/bin/bash

function f ( )
{
    echo "$2"
}
command="f --option=\"One Two Three\" --another_option=\"Four Five Six\""
$command

f --option="One Two Three" --another_option="Four Five Six"

First calling is wrong, second - right

$> ./test.sh 
Two
--another_option=Four Five Six

Answer 1

BASH FAQ entry #50: "I'm trying to put a command in a variable, but the complex cases always fail!"

TL;DR: Use an array.

command=(f --option="One Two Three" --another_option="Four Five Six")
"${command[@]}"

Answer 2

You could also use the evil eval:

eval "$command"
