java - br.readLine() for non terminating streams? -


i writing small utility displays list of running/stopped services.it reads console output , uses output after further processing. program hangs @ br.readline() possibly because not able find terminating character in stream. here excerpt code.

    try {             string mainfile="";             string temp="";             process p = runtime                     .getruntime()                     .exec(system.getenv("windir")                             + "\\system32\\windowspowershell\\v1.0\\"                             + "powershell.exe  get-service | format-list name , status , displayname ");             p.waitfor();             inputstream = p.getinputstream();             inputstreamreader isr = new inputstreamreader(i);             bufferedreader br = new bufferedreader(isr);             while ((temp = br.readline())!=null) {                 mainfile = mainfile + temp + "\n";             }         } catch (exception err) {             err.printstacktrace();         }         system.out.println(mainfile);

unfortunately because of problem last syso statement never printed.any pointers solve issue ?
