linux - 在 for 循环中从数组创建目录

Question

我有一组客户姓名，我想用它们来制作目录。下面是我正在运行的代码：

$ echo "$customerArray=( customer1 customer2 customer3 customer4 customer5 )"

for customerName in $( customerArray ); 
do
    mkdir -p /home/$customerName
    mkdir -p /home/$customerName/outbound
    mkdir -p /home/$customerName/outbound_backup
    mkdir -p /home/$customerName/dropoff
done

谁能向我解释我做错了什么？

Answer 1

这将是使用 大括号扩展的可行替代方案

customerArray=(customer1 customer2 customer3 customer4 customer5)
for customerName in ${customerArray[*]}
do
  mkdir -p /home/$customerName/{outbound,outbound_backup,dropoff}
done

Answer 2

您不能在字符串文字内设置变量，我很确定这$( customerArray )也是无效的。请尝试以下操作：

customerArray=(customer1 customer2 customer3 customer4 customer5)
for customerName in ${customerArray[@]}
do
    ...
done

您需要将数组变量引用为${customerArray[@]}或${customerArray[*]}。bash 手册对此进行了更深入的描述。
