如何在java程序中運行unix enq命令

Question

以下是將文件添加到隊列的unix命令。

enq -P QueueName:PrinterName FileName 

是否可以使用java運行上述命令。

Answer 1

是的，有可能使用ProcessBuilder：

ProcessBuilder builder = 
      new ProcessBuilder("enq", "-P", "QueueName", "FileName"); 
Process process = builder.start(); 
InputStreamReader streamReader = new InputStreamReader(process.getInputStream()); 
BufferedReader reader = new BufferedReader(streamReader); 
String line; 
while ((line = reader.readLine()) != null) { 
    System.out.println(line); 
}

Answer 2

Process p = Runtime.getRuntime().exec(new String[]{"enq", "-P", "QueueName:PrinterName FileName"});
