Not having a Linux laptop handy I can't test it, but my point is that
text parsing of that nature can be done directly by Python. You can
snip out the "open" or "close" easily with one, maybe two lines of
code at the most, and that without dropping to a shell, a completely
superfluous 'cat' process, and awk. You then capture the STDOUT of
that and promptly print it to your own STDOUT. Why not either do it
truly in Python, or do it directly in a shell script and skip the
Python interpreter?
