java 异步执行bash命令

要在Java中异步执行Bash命令，可以使用Java的ProcessBuilder类和Runtime类。

使用ProcessBuilder类：

ProcessBuilder processBuilder = new ProcessBuilder("bash", "-c", "your_bash_command");
processBuilder.redirectErrorStream(true);
Process process = processBuilder.start();

// 异步读取输出
InputStream inputStream = process.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

while (true) {
    String line = reader.readLine();
    if (line == null) {
        break;
    }
    System.out.println(line);
}

// 等待命令执行结束
int exitCode = process.waitFor();
System.out.println("exit code: " + exitCode);

使用Runtime类：

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("bash -c your_bash_command");

// 异步读取输出
InputStream inputStream = process.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

while (true) {
    String line = reader.readLine();
    if (line == null) {
        break;
    }
    System.out.println(line);
}

// 等待命令执行结束
int exitCode = process.waitFor();
System.out.println("exit code: " + exitCode);

注意，以上代码只是演示如何异步执行Bash命令，实际使用时需要根据具体情况调整。
