My rational is that all Linux distros are not created equal.
One comes with one certain set of utilities and another can
have different ones.  I can't always depend on a given
utility being there.  And there is not way to know the
names of same utility across all distros.  This is especially
a problem when comparing .rpm with .deb based distros.

In cases where I have to use an external program, I mean in
cases where there is no apparent Python solution, I check
for the existence of that program and just skip over that
section of the code if it is not found.

BTW here is a link for the Bash script I mentioned in case
you would like to take a look at it.  The guy who wrote
it had only been learning Bash for a few months.  Not bad.
I have tried to tweak an interest in him for Python but
he sticks with Bash.  He says that is the best language
for programming on Linux and he is not interested in GUI
programming.
