java 调用linux命令行

Java可以通过Runtime类或ProcessBuilder类来调用Linux命令行。

使用Runtime类调用Linux命令行：

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("ls -l"); // 执行Linux命令行
InputStream input = process.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
String line = null;
while ((line = reader.readLine()) != null) {
    System.out.println(line); // 输出命令行执行结果
}

使用ProcessBuilder类调用Linux命令行：

ProcessBuilder builder = new ProcessBuilder("ls", "-l");
Process process = builder.start();
InputStream input = process.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
String line = null;
while ((line = reader.readLine()) != null) {
    System.out.println(line); // 输出命令行执行结果
}
