See the following for more info: http://www.faqs.org/docs/diveintopython/kgp_stdio.html You could send the output to a variable and create a file-like stream too. Either way, read the file (or stream) and then for each line, split it on the space. Then you can do the compare and use the email module to email you the result should it go over your specified amount. By the by, if you're using Python 2.4 or above, you should switch to using the subprocess module rather than using os.system since the latter is being deprecated. For more on file objects, see the docs: http://docs.python.org/lib/bltin-file-objects.html or there's this good article: http://www.devshed.com/c/a/Python/File-Management-in-Python/ And the email module is explained quite well in the docs too: http://docs.python.org/lib/module-email.html Mike -- http://mail.python.org/mailman/listinfo/python-list
