Java CLI如何执行Shell脚本

在Java中，你可以使用Runtime类或ProcessBuilder类来执行Shell脚本。下面是两种方法的示例：

方法1：使用Runtime类

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

public class ExecuteShellScript {
    public static void main(String[] args) {
        try {
            String scriptPath = "/path/to/your/shell-script.sh";
            Process process = Runtime.getRuntime().exec(new String[]{"bash", scriptPath});

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

            int exitCode = process.waitFor();
            System.out.println("Exit Code: " + exitCode);
        } 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 ExecuteShellScript {
    public static void main(String[] args) {
        try {
            String scriptPath = "/path/to/your/shell-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);
            }

            int exitCode = process.waitFor();
            System.out.println("Exit Code: " + exitCode);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

这两个示例都会执行指定的Shell脚本，并将脚本的输出打印到控制台。请确保将scriptPath变量替换为你的Shell脚本的实际路径。
