Hi Alan, Thanks for your reply. My answer to why I am using os.popen could be a lame one - I have used it extensively in various places before and it has been working well and so was hung up on using it. Now I replaced it by subprocess.check_output with appropriate parameters and it seems to be working. Does that mean this is one of the limitations of os.popen? I am not sure. Sorry for not giving details on the OS and python version I am using: Ubuntu and Python3. Thanks, SM
