Tar is one of those commands that has a very brief man page and a vastly
larger and more detailed info. It has been several years since I looked
but I think that if you'll browse through "info tar" you'll find an
example for what you want/need to do. Also, you might want to look for
script "back2cd". It appeared in a magazine a couple years ago but I
have managed to Google only broken links. (I probably have a copy of it
in my old RH6.0 archive if you can't find it on the net.)
