It's a good idea to know what will happen BEFORE you unpack an unknown
archive.  I use the following little aliases to inspect things before
I "untar":

# Show the contents of a *.tar file
alias showtar	'tar vtf \!:1'
# Show the contents of a *.tar.Z file
alias showZ	'zcat \!:1 | tar vtf -'

To actually unpack:

# Unpack a *.tar file:
alias untar	'tar xvf \!:1'
# Unpack a *.tar.Z file:
alias untarZ	'zcat \!:1 | tar xvf -'

I have seen this a couple of times now so I will post rather
than email. You can use GNU tar and say

to show the content (verbose)
% tar -vtf foo.tar
% tar -zvtf foo.tar.Z 

to unpack
% tar -xf foo.tar
% tar -zxf foo.tar.Z 

On NeXTstep3.0, GNU tar 1.10 does come with the system as
/usr/bin/gnutar so you don't have to install it.
Latest version I know of is 1.11.1 which compiles fine on NeXTs.
I don't mean to flame or anything but this may save you some
effort.

Another feature I like is that you can do remote tars
using GNU tar, which we use (since we don't have tape
drives hooked up to the NeXTs.)
