如何将 ProcessBuilder 输出重定向到字符串？

我正在使用以下代码来启动流程构建器。我想知道如何将其输出重定向到String.

ProcessBuilder pb = new ProcessBuilder(
    System.getProperty("user.dir") + "/src/generate_list.sh", filename);
Process p = pb.start();

我尝试使用ByteArrayOutputStream但这似乎不起作用。

读自InputStream。您可以将输出附加到StringBuilder:

BufferedReader reader = 
                new BufferedReader(new InputStreamReader(process.getInputStream()));
StringBuilder builder = new StringBuilder();
String line = null;
while ( (line = reader.readLine()) != null) {
   builder.append(line);
   builder.append(System.getProperty("line.separator"));
}
String result = builder.toString();
