Is the program actually producing output progressively? I just tried your exact code with "dir /ad /s /b" and it worked fine, producing output while the dir was still spinning (obviously setting shell=True to make that work, but I don't think that'll make a difference). It may be that pip buffers its output. Is there a parameter to pip to make it pipe-compatible? ChrisA -- http://mail.python.org/mailman/listinfo/python-list
