树莓派 3 型号 b 中的 Rc.local

Question

我正在开发 raspberry pi 3 model b arm 版本，运行 Debian 我需要在启动时运行一个脚本，我正在使用 /etc./Rc.local 执行此操作我遵循了这本食谱：https://www.cyberciti.biz/faq/how-to-enable-rc-local-shell-script-on-systemd-while-booting-linux-system/ 一切工作正常，有一些回显日志我发送到 log.txt 文件，我看到命令正在执行，但当我尝试运行脚本时，我确实需要它不起作用，Rc 中的所有其他命令.local 文件正在执行，但没有对我来说最重要的文件。

/etc/rc.local 文件：

> ##Reload deamon
 sudo systemctl daemon-reload && echo "Daemon -> SUCCESS" >> /tmp/mounter_test.txt || echo "Daemon -> FAIL" >>
> /tmp/mounter_test.txt
> ##Checking which user is running
> whoami >> /tmp/mounter_test.txt
> ##Check log
> echo "First try" >> /tmp/mounter_test.txt
> enc /opt&
> 
> if [ $? -eq 0 ]; then
>         echo "The mounter is running" >> /tmp/mounter_test.txt else
>         echo "The mounter has failed!!" >> /tmp/mounter_test.txt fi
> 
> exit 0

猫/tmp/enc_test.txt

SUCCESS
root
First try
The mounter is running

systemctl staus rc-local.service ----启动后----

更重要的一件事是，如果我在终端中运行 /etc/rc.local，则加密正在工作，因此只有此命令和 rc.local 中的命令。

非常感谢您的帮助！谢谢你们 ：）
