programmatically extract tar.gz in a single step (on windows with 7zip)

Question

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?

Answer 1

Perhaps the GnuWin32 ports of gzip and tar are what you need (scroll down)

Answer 2

Maybe try something like adding a temporary .tgz extension?

MOVE %1 %1.tgz
7z x %1.tgz
MOVE %1.tgz %1

I might be wrong, but I believe 7zip will unzip tgz files all at once (instead of with tar.gz files).

Answer 3

Try the tartool utility http://tartool.codeplex.com/

I was frustrated by the lack of a cmd line utility for such a simple task and created it for this exact reason.

The code is open source and uses SharpZipLib library.
