It looks like you want to use the manifest list from a tar package (tar -t) to tell another tar command what to archive. Is this correct? Also, your grep's in the first command line cancel each other out, picking only lines that have "gz" in them anywhere and then removing those same lines using the -v option to negate the "gz" matches (effectively leaving you with no lines of output). Provide a little more clarification on what you are trying to do and we can all possibly lend a hand.
