Uncompressing but not extracting tar.Z file

Hi
I have a few hundred files with extension .tar.Z. These files were archived (tar) and compressed (Z) on a UNIX system. I need to unzip them but not extract them. In other words they need to go to .tar extension. I would like to do this on my MAC or on a windows pc. I do not have a UNIX system to do this on at present.

uncompress blah.tar.Z

That assumes you really meant capital Z.

If it's a lower case z, then use gunzip instead of uncompress.

Well, that's embarrassing! I thought I had tried that command and that it failed. But it worked just fine. Thank you.

Note that Apple's OS X is a UNIX-branded operating system.
