Assuming you really want to use egrep, why?
You could process the file directly in Python searching for your strings
(using the re module if need be).
Using Popen makes sense if the command is doing a lot of work or is very
CPU intensive. But for file processing its probably as easy to just use
Python to scan the log files directly.
But if you are really doing something more complex I see that others
have answered the Popen() question...
