stream of a Process returned by Runtime.exec()
How do I print to stdout the output string obtained executing a command?
So Runtime.getRuntime().exec() would return a Process , and by calling getOutputStream() , I can obtain the object as follows, but how do I display the content of it to stdout?
OutputStream out = Runtime.getRuntime().exec("ls").getOutputStream();
Thanks
I believe you are trying to get the output from process, and for that you should get the InputStream .
InputStream is = Runtime.getRuntime().exec("ls").getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader buff = new BufferedReader (isr);
String line;
while((line = buff.readLine()) != null)
System.out.print(line);
You get the OutputStream when you want to write/ send some output to Process.
将流转换为字符串，如将Get OutputStream转换为字符串所述，并简单地使用Sysrem.out.print（）
