PROBLEM: I would like to be able to extract tar.gz files in a single step. This makes my question almost identical to this one: stackoverflow question for tar-gz.
My question is almost the same, but not the same, because I would like to do this on windows using 7zip command-line (or something similar) inside a bat file or ruby/perl/python script.
QUESTION: This seemingly simple task is proving to be more involved than the first appearance would make it out to be. Does anyone have a script that does this already?
