在java中的特定目录中运行shell命令

 public class ShellCommandExample {

     public static void main(String[] args) {

         try {

             // 指定目录

             String directory = "/path/to/directory";

             // 执行的shell命令

             String command = "ls -l";

             // 创建Runtime对象

             Runtime runtime = Runtime.getRuntime();

             // 执行命令

             Process process = runtime.exec(command, null, new File(directory));

             // 获取命令执行结果

             BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));

             String line;

             while ((line = reader.readLine()) != null) {

                 System.out.println(line);

             }

             // 等待命令执行完成

             int exitCode = process.waitFor();

             System.out.println("Command executed with exit code: " + exitCode);

         } catch (IOException | InterruptedException e) {

             e.printStackTrace();

         }

     }

 }
