如何在bash中为数组赋值？

array=("value1" "value2" "value3")

array[0]="value1"
array[1]="value2"
array[2]="value3"

string="value1 value2 value3"
array=($string)

read -p "Enter values separated by space: " -a array

#!/bin/bash

# 方法一：直接赋值
array1=("value1" "value2" "value3")

# 方法二：使用索引赋值
array2[0]="value1"
array2[1]="value2"
array2[2]="value3"

# 方法三：从字符串分割赋值
string="value4 value5 value6"
array3=($string)

# 方法四：使用read命令赋值
echo "Enter values separated by space for array4:"
read -p "" -a array4

# 打印数组内容
echo "Array 1: ${array1[@]}"
echo "Array 2: ${array2[@]}"
echo "Array 3: ${array3[@]}"
echo "Array 4: ${array4[@]}"

# 获取数组长度
echo "Length of Array 1: ${#array1[@]}"
echo "Length of Array 2: ${#array2[@]}"
echo "Length of Array 3: ${#array3[@]}"
echo "Length of Array 4: ${#array4[@]}"
