I think the OP's worry is not whether it can be done, but he wants to
avoid the time and CPU cycles involved in the gunzip step. Since he has
his entire home directory in the tarball, even extracting a single file
requires tar to decompress the entire tarball before it can extract that
I think the only solution in this case is to do
$ gunzip bobg.tar.gz
and keep the resulting bobg.tar file in some easy to access area. A
$ tar xf bobg.tar /path/to/my/file
should be fast and easy to do.
Apologies if my understanding of the OP's problem is incorrect.
