linux - 在启动时运行单声道应用程序而不创建服务

Question

我有一个单声道 C# 单声道应用程序，带有一个简单的菜单，甚至不需要输入即可工作。我想要做的是在启动时启动应用程序，而不使用 ubuntu 的 StartUp。我使用的是 raspbian，并且希望将应用程序作为后台进程而不是服务启动。

到目前为止我所拥有的是启动它的命令:

start-stop-daemon --start --quiet --pidfile /home/pi/pid/EDM.pid --exec /home/pi/Mono/EDM.exe --test

我需要的是在操作系统启动时运行此命令。我已经尝试过这个脚本:

        #! /bin/sh
    ### BEGIN INIT INFO

    # Short-Description: Start daemon at boot time
    # Description:       Enable service provided by daemon.

       # If the above conditions are not satisfied then add some other code

我使用 update-rc.d mn 默认值，它显示以下错误: 更新-rc.d:

using dependency based boot sequencing
insserv: Script mn is broken: incomplete LSB comment.
insserv: missing `Provides:' entry: please add.
insserv: missing `Required-Start:' entry: please add even if empty.
insserv: missing `Required-Stop:'  entry: please add even if empty.
insserv: missing `Default-Start:'  entry: please add even if empty.
insserv: missing `Default-Stop:'   entry: please add even if empty.
insserv: Default-Start undefined, assuming empty start runlevel(s) for script `mn'
insserv: Default-Stop  undefined, assuming empty stop  runlevel(s) for script `mn'

有什么想法吗？

最后，最好的方法是制作一个极其简单的 bash 脚本来运行以下命令:

#!/bin/bash
start-stop-daemon --start --background -m --oknodo --pidfile /home/pi/pid/MonoDaemon.pid --exec /usr/bin/mono -- /home/pi/Mono/EDM.exe

之后我在/etc/init.d/rc.local 中添加了一行

/bin/bash /etc/init.d/mnw
