运行 bash 脚本 .Net Core 2.2 C#

  • 772

您需要从用 C# .net core 2.2 编写的程序运行用 Bash 编写的脚本。

cd /home/jman/myapp/

。/测试

在 C# 程序中，我通过启动命令（帮助程序）来完成：

 public string RunBashCommand(string cmd, Dictionary<string, string> environmentVariables = null)
    {
        using (var process = new Process())
        {
            process.StartInfo = new ProcessStartInfo
            {
                FileName = "/bin/bash",
                Arguments = $"-c \"{cmd}\"",
                RedirectStandardOutput = true,
                UseShellExecute = false,
                CreateNoWindow = true
            };
            if (environmentVariables != null)
                foreach (var variable in environmentVariables)
                {
                    process.StartInfo.EnvironmentVariables[variable.Key] = variable.Value;
                }

            process.Start();
            var result = process.StandardOutput.ReadToEnd().Trim('\n').Trim('\r');
            process.WaitForExit();
            return result;
        }
    }

和调用本身：

 private void LoadDevice()
    {
        Console.WriteLine(scriptRunner.RunBashCommand("cd /home/jman/myapp/"));
        Console.WriteLine(scriptRunner.RunBashCommand("./test"));
    }

我在 Ubuntu 中运行一个用 C# 编写的应用程序：

dotnet MyCoreApp.dll

我得到一个错误：

/bin/bash：测试：找不到命令

实际上如何正确运行脚本？

    所以，感谢@PotroNik 的建议，我设法运行了 Bash 脚本。

    辅助类创建：

    public class BashShellHelper
{
    public string RunBashCommand(string cmd, Dictionary<string, string> environmentVariables = null)
    {
        using (var process = new Process())
        {
            process.StartInfo = new ProcessStartInfo
            {
                FileName = "/bin/bash",
                Arguments = $"-c \"{cmd}\"",
                RedirectStandardOutput = true,
                UseShellExecute = false,
                CreateNoWindow = true
            };
            if (environmentVariables != null)
            {
                foreach (var variable in environmentVariables)
                {
                    process.StartInfo.EnvironmentVariables[variable.Key] = variable.Value;
                }
            }

            process.Start();
            var result = process.StandardOutput.ReadToEnd().Trim('\n').Trim('\r');
            process.WaitForExit();
            return result;
        }
    }

    public void RunBushScript(string cmd)
    {
        var process = new Process
        {
            StartInfo = new ProcessStartInfo
            {
                FileName = "/bin/bash",
                Arguments = $"-c \"{cmd}\"",
                RedirectStandardInput = true,
                RedirectStandardOutput = true,
                RedirectStandardError = true,
                UseShellExecute = false,
                CreateNoWindow = true
            },
            EnableRaisingEvents = true
        };

        process.Start();
        process.BeginOutputReadLine();
        process.BeginErrorReadLine();
    }
}

    在主程序中实现了以下方法：

      private readonly BashShellHelper scriptRunner =
        new BashShellHelper();
 private readonly loadDevScript = "cd /home/jman/myapp/;./test_load";
 private readonly unloadDevScript = "cd /home/jman/my_second_app/;./test_unload";

 public void LoadDevice()
    {
        Console.WriteLine(scriptRunner.RunBashCommand($"{loadDevScript}"));
    }

    以及启动脚本以卸载设备的方法：

    public void UnloadDevice()
    {
        deviceManager.CloseDevice();
        Console.WriteLine(scriptRunner.RunBashCommand($"{unloadDevScript}"));
    }
