如何在bash中使用全局数组？

declare -a global_array=("value1" "value2" "value3")

global_array=("value1" "value2" "value3")

echo "First element: ${global_array[0]}"

function my_function {
    echo "First element: ${global_array[0]}"
}

global_array[1]="new_value"

echo "Array length: ${#global_array[@]}"

#!/bin/bash

# 声明全局数组
global_array=("value1" "value2" "value3")

# 定义一个函数，用于访问全局数组
function my_function {
    echo "First element: ${global_array[0]}"
}

# 修改全局数组
global_array[1]="new_value"

# 获取数组长度
echo "Array length: ${#global_array[@]}"

# 调用函数
my_function
