语法错误：重定向意外的Netcat busybox

Question

I'm new to netcat and trying to use the same line in the busybox as i do in my pc. 我是netcat的新手，并尝试在busybox中使用与在PC中相同的行。

I want to know how I can change the redirection operator. 我想知道如何更改重定向运算符。

nc -w 30 IP 3031 -e <<<"info"

this is the error 这是错误

-sh: syntax error: redirection unexpected

I think it doesn't like <<<, but what should I change it to? 我认为它不喜欢<<<，但是我应该将其更改为什么？

btw this script throws the information it gets to the screen, by sending "info" 顺便说一句，此脚本通过发送“ info”将其获取的信息扔到屏幕上

Answer 1

只需更改为：

echo "info" | nc - w 30 IP 3031
