Shell如何遍历数组？
数组:A=(a b c d)引用数组:${A[@]}${A[*]}访问数组成员${A[0]}计算数组长度${#A[@]}${#A[*]}数组重新赋值A[2]=xyz如何遍历数组实例:tee ./images.sh <<-'EOF'#!/bin/bashimages=(registry.cn-hangzhou.aliyuncs.com/lfy_k8s_images/kube-apiser

今天离线安装K8s，脚本中有使用到遍历数组。
复习一下shell数组的使用。
数组:
- A=(a b c d)
引用数组:
- ${A[@]}
- ${A[*]}
访问数组成员
- ${A[0]}
计算数组长度
- ${#A[@]}
- ${#A[*]}
数组重新赋值
- A[2]=xyz
如何遍历数组实例:
tee ./images.sh <<-'EOF'
#!/bin/bash
images=(
