Python 2.6 (why are you using the oldest Python minor version?) introduced string.format(), so you should use that instead of the old string format operator (“%”): logging.error("Can't run {0}; got {1} ({2:d})!".format(cmd, err, ret)) <https://docs.python.org/2.6/library/stdtypes.html#str.format> On the other hand, you do not need the format operator to begin with: logging.error("Can't run %s; got %s (%d)!", cmd, err, ret) <https://docs.python.org/2.6/library/logging.html#logging.error> > return False > except Exception as e: > logging.exception("Failed to run %s got %s" % (cmd, e)) See above. > return False > logging.info("Mount /tmp.....Done !!!") > time.sleep(30) > > > Iam on python 2.6 and Linux , I need you inputs on how to ignore an > specific error when the mount fails (Polite people would *ask* a *question*.) > In general the mount has zero status if it succeeds and anon-zero exit > status if it fails.

Also need to add this check only for mount case i.e mount > /filesystems and not scanner_start Most simple solution for this: Do not use a loop. More "complicated" solution: Use an “if” statement. <http://www.catb.org/~esr/faqs/smart-questions.html> -- PointedEars Twitter: @PointedEars2 Please do not cc me. / Bitte keine Kopien per E-Mail. -- https://mail.python.org/mailman/listinfo/python-list
