英文:
Don't kill process when dotnet project shut down
问题
我正在为Linux系统（Debian）开发一个.NET应用程序。我想从我的应用程序上运行Linux命令。我正在使用以下方法运行命令。如果可能的话，我真的不想改变它。
public static async Task<Process> RunCommandAsync(string command)
{
string cmd = command.Replace(""", "\\"");
Process process = new()
{
StartInfo = new ProcessStartInfo
{
FileName = "/bin/bash",
Arguments = $"-c \"{cmd}\"",
RedirectStandardOutput = true,
RedirectStandardError = true,
UseShellExecute = false,
CreateNoWindow = true,
}
};
process.Start();
await process.WaitForExitAsync();
return process;
}
我的目标是在项目内启动一个进程，而在关闭项目时不终止它。我想只使用一个命令来实现这一点。我尝试了类似于这样的内容 sudo nohup sh -c 'ping google.com' > /dev/null &，我以为这会起作用，但是当我关闭项目时，进程也被终止了。
简而言之，在这个示例中，我想在关闭项目后继续进行ping操作。

在这里，为了简单起见，我给出了ping的示例。实际上，该应用程序位于一个Debian软件包中，并且同时运行两个应用程序，都作为服务。在某个时刻，我想卸载该应用程序，这会停止两个服务。我首先停止负责此操作的服务，然后另一个服务永远不会停止，应用程序无法正确卸载。
英文:
I'm working on a dotnet app for a Linux system (debian). I want to run commands on Linux from my app. I'm running commands using this method. I really don't want to change it if possible.
public static async Task<Process> RunCommandAsync(string command)
{
string cmd = command.Replace("\"", "\\\"");
Process process = new()
{
StartInfo = new ProcessStartInfo
{
FileName = "/bin/bash",
Arguments = $"-c \"{cmd}\"",
RedirectStandardOutput = true,
RedirectStandardError = true,
UseShellExecute = false,
CreateNoWindow = true,
}
};
process.Start();
await process.WaitForExitAsync();
return process;
}
My goal is to start a process within the project and not killing it when I shut down the project. I wanted to use only a command. I tried something like this sudo nohup sh -c 'ping google.com' > /dev/null &, which I though that would work but when I shut down the project the process is also terminated.
In short, in this example I wanted to continuing the ping even after I shut down the project.
Edit 1
Here, for simplicity, I gave the example of a ping. In reality the app is in a debian package and there are two apps running at the same time, both as services. At some point I want in uninstall the app, which stops both services. I stop the service responsible for this first, and then the other service is never stop and the app isn't uninstalled correctly.

我找到了一个解决方案。我创建了一个服务（finish.service），如下所示：
[Unit]
Description=卸载 app1 并安装 app2
[Service]
Type=oneshot
ExecStart=/opt/finish/finish.sh
WorkingDirectory=/opt/finish/
StandardOutput=journal
StandardError=journal
其中 "/opt/finish/finish.sh"（简化的代码）：
#!/bin/bash
sudo apt purge app1;
sudo apt install app2;
在我的应用程序中，当我想要卸载它并安装一个新应用时，我只需调用：
sudo systemctl start finish.service
英文:

Description=Uninstall app1 and install app2
[Service]
Type=oneshot
ExecStart=/opt/finish/finish.sh
WorkingDirectory=/opt/finish/
StandardOutput=journal
StandardError=journal
Where "/opt/finish/finish.sh": (simplified code)
#!/bin/bash
sudo apt purge app1;
sudo apt install app2;
In my app, when I want to uninstall it and install a new one I simply call
sudo systemctl start finish.service
