bash - BASH - 将数组中的值读入命令

问题描述

我对 bash 比较陌生，我需要使用 Azure CLI 为 Azure MySQL 服务器实例创建 127 个 VNET 安全规则，这需要规则名称和关联的子网 ID。规则名称是子网名称。我可以将子网名称和 ID 读取到数组中，并且可以看到填充了数组

mapfile -t vnetRULEname < <(az network vnet subnet list -g resourcegroup --vnet-name vnet --query "[].{name:name}" -o table)

mapfile -t vnetRULEid < <(az network vnet subnet list -g resourcegroup 
--vnet-name vnet --query "[].{objectID:id}" -o table)

然后我想运行以下命令，以便它使用数组中的每个名称和 ID 创建 127 条规则来创建规则。

az mysql server vnet-rule create -n <rule name from vnetRULEname> -g resourcegroup -s servername --subnet <subnet ID from vnetRULEid>

将子网名称和 ID 值都读入同一个数组会更好吗？

在 bash 脚本中执行此操作的最佳方法是什么？我如何告诉它忽略名为 Name 和 ID 的列标题以及名为 GatewaySubnet 的子网？

输出示例（子网名称）

Name
-------------
GatewaySubnet
app-host-001
app-host-002
app-host-003
app-host-004
app-host-005

输出样本（子网 ID）

ObjectID
----------------------------------------------------------------------------- 
/subscriptions/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/resourceGroups/resourcegroup/providers/Microsoft.Network/virtualNetworks/vnet/subnets/GatewaySubnet
/subscriptions/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/resourceGroups/resourcegroup/providers/Microsoft.Network/virtualNetworks/vnet/subnets/app-host-001
/subscriptions/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/resourceGroups/resourcegroup/providers/Microsoft.Network/virtualNetworks/vnet/subnets/app-host-002
/subscriptions/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/resourceGroups/resourcegroup/providers/Microsoft.Network/virtualNetworks/vnet/subnets/app-host-003
/subscriptions/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/resourceGroups/resourcegroup/providers/Microsoft.Network/virtualNetworks/vnet/subnets/app-host-004
/subscriptions/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/resourceGroups/resourcegroup/providers/Microsoft.Network/virtualNetworks/vnet/subnets/app-host-005

跑步

#!/bin/bash

mapfile -t vnetRULEname < <(az network vnet subnet list -g resourcegroup --vnet-name vnet --query "[].{name:name}" -o table)
mapfile -t vnetRULEid < <(az network vnet subnet list -g resourcegroup --vnet-name vnet --query "[].{objectID:id}" -o table)
echo "These are vnetRULEname: ${vnetRULEname[@]}"
echo "These are vnetRULEids : ${vnetRULEid[@]}"

正如我所期望的那样，在屏幕上显示两个数组的内容。但如果我跑

mapfile -t vnetRULEname < <(az network vnet subnet list -g resourcegroup --vnet-name vnet --query "[].{name:name}" -o table)
mapfile -t vnetRULEid < <(az network vnet subnet list -g resourcegroup --vnet-name vnet --query "[].{objectID:id}" -o table)
#echo "These are vnetRULEname: ${vnetRULEname[@]}"
#echo "These are vnetRULEids : ${vnetRULEid[@]}"
sizeofarrays=${#arr[@]}
for (( i=0 ; i < sizeofarrays ; i++ ))
do
    az mysql server vnet-rule create --name "${vnetRULEname[$i]}" --resource-group resourcegroup --server server --subnet "${vnetRULEid[$i]}"
done
echo ${arr[@]}  ## print all the array
echo ${#arr[@]} ## print its size

我明白了

解决方案

那么for循环呢？

echo "These are vnetRULEname: ${vnetRULEname[@]}"
echo "These are vnetRULEids : ${vnetRULEid[@]}"
sizeofarrays=${#arr[@]}
for (( i=0 ; i < sizeofarrays ; i++ ))
do
    az mysql server vnet-rule create -n "${vnetRULEname[$i]}" -g resourcegroup -s servername --subnet "${vnetRULEid[$i]}"
done

希望对你有帮助！:)

编辑 ：

这是获取数组大小和元素的方式

echo ${arr[@]}  ## print all the array
echo ${#arr[@]} ## print its size

## so in your case sizeofarray should be equal to ${#arr[@]}
