java - 在java中运行windows powershell命令

Question

我能够在 Windows PowerShell 中运行此命令。

Add-Content -Path C:/Users/User/Desktop/sda.txt -Value "`nThis is the last line"

我尝试通过 Java 运行类似的命令，但它没有执行该命令。

Runtime runtime = Runtime.getRuntime();
System.out.println("powershell Add-Content -Path C:/Users/User/Desktop/sda.txt -Value " + "\"`nThis is the last line\"");
runtime.exec("powershell Add-Content -Path C:/Users/User/Desktop/sda.txt -Value " + "\"`nThis is the last line\"");

按照aquaraga的建议进行第二次尝试

Runtime runtime = Runtime.getRuntime();
Process proc;
System.out.println("powershell Add-Content -Path C:/Users/User/Desktop/sda.txt -Value " + "\"`nThis is the last line\"");
proc = runtime.exec("powershell Add-Content -Path C:/Users/User/Desktop/sda.txt -Value " + "\"`nThis is the last line\"");
try {
            proc.waitFor();
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

将 powershell 命令参数括在单引号中:

proc = runtime.exec("powershell Add-Content -Path C:/Users/User/Desktop/sda.txt -Value " + "\"'`nThis is the last line'\"");
