问题解决

len=${#list_name[*]} # 数组的长度 name=${list_name[@]} # 列出所有的数组 for 循环 for ((i=0; i<=len; i ++)) do order=${list_order[i]} eval $order="for i in $name ;do systemctl stop $i --no-pager && sleep 5s;done" done i ++ ： i=$(($i+1)) 如下这样，双引号中的$name 还是会获取变量name的数值，而其他的都是常量，不会进行bash a="for i in $name ;do systemctl stop $i --no-pager && sleep 5s;done" a=b $a=123 因为shell 不能二次进行解析，使用eval 字符串转数组 list_name=`cat service.txt` list_name=(${list_name//,/})
