java如何调用linux脚本

在Java中，你可以使用Runtime类或ProcessBuilder类来调用Linux脚本

方法1：使用Runtime类

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

public class Main {
    public static void main(String[] args) {
        try {
            String scriptPath = "/path/to/your/script.sh";
            Process process = Runtime.getRuntime().exec("bash " + scriptPath);

            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            process.waitFor();
            reader.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

方法2：使用ProcessBuilder类

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        try {
            String scriptPath = "/path/to/your/script.sh";
            ProcessBuilder processBuilder = new ProcessBuilder("bash", scriptPath);
            processBuilder.redirectErrorStream(true);

            Process process = processBuilder.start();

            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            process.waitFor();
            reader.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

在这两个示例中，我们分别使用Runtime.getRuntime().exec()和ProcessBuilder类来执行Linux脚本。请注意，你需要将scriptPath变量设置为你要执行的脚本的实际路径。这两个示例都会运行脚本并将输出打印到控制台。
