I'm looking into subprocess.Popen docs. I've launch the program with its arguments and that's smooth. I'm expecting to read the output by *comunicate()* at every line that prgram may blow during the process, but the output is given only when the child process is ended. I'd like to process the lines to display an information in percentage during the running time of the child. Sorry but I'm poor of know-how, so I'm stuck over to find a clue. -- goto /dev/null
