java 执行linux命令并获取pid

你可以使用Java中的Runtime类来执行Linux命令。以下是一个简单的示例，可以执行Linux命令并获取其pid：

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class LinuxCommandExecutor {
    public static void main(String[] args) {
        String command = "your linux command here";
        try {
            Process process = Runtime.getRuntime().exec(command);
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                // do something with the output
            }
            int pid = process.pid(); // get the pid
            process.waitFor();
            reader.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

请注意，此代码仅是示例，你需要将“your linux command here”替换为你要执行的实际命令。
