New submission from Georgiy Treyvus:
Basically in a lot of situations in recent times I've had to make sure a bunch
of files are all the same. Now diff is great but it only lets me pass two
files. diff3 and sdiff also aren't what I'm looking for. So I decided to write
my own little script that does that.
I was doing a few crude preliminary tests on an early version of the utility
and that's when shit hit the fan. For reasons I can't explain Python 2.7.5 in
some circumstances said that getstatusoutput wasn't an attribute of the
commands module. The program executed fine though under Python 3.3.2.
Anyway here's some shell output which will leave you folks scratching your head
as much as I am. I have several times checked the syntax and I just simply
don't think I'm doing anything wrong. What are your thoughts?
