作为系统服务运行 shell 脚本

我正在将 shell 脚本作为系统服务运行，但它却无法正常运行

input="/home/sipl/inf"
while read -r line
do
  sudo iptables -t nat -i $line -A PREROUTING -p tcp --dport 1:65535 -j REDIRECT --to-port 5000
done < "$input"

答案1

从日志中你可以看出：

COMMAND=/usr/sbin/iptables -t nat -i -A PREROUTING ...

您没有line接口的变量名称。更正此问题，您将获得成功。这应该是这样的：

COMMAND=/usr/sbin/iptables -t nat -i eth0 -A PREROUTING ...
