Hi,

not being very familiar with Unix I have a simple (not for me:( )
question.
I have got two file with a .tar extension:
file1.tar.gz
and
file2.tar.Z

The first one is a gzip file, created by the gzip command (from GNU).
Basically, this is a tar file being compressed. To uncompress and untar
this file, use the
following command :

gzcat file2.tar.gz | tar xvf -

The second one is a tar-compressed file, created by the Unix compress
command applied to a tar file (e.g. tar cf - <files> | compress >
file2.tar.Z). To uncompress and untar this file, use the following
command :

zcat file2.tar.Z | tar xvf -
or

gzcat file2.tar.Z | tar xvf -

I came across so-called "tar-gzipped" files with file names like
file1.tzg

How to "unscramble" such a file? I tried both to apply gunzip first,
and to apply tar first. Both commands complain about wrong format.

Or use TkZip http://www.pcnet.com/~proteus/TkZip/TkZip.html

I agree about mv; also if you have gnu tar which recongizes
.tgz extendion.

(not all Unixes have gzip/gunzip/gzcat, all have compress/uncompress/zcat,
which for me remains a good reason to use .Z and not .gz files)

Also and anyhow, the above commands can also be combined in a pipeline,
avoiding the creation of the uncompressed file on disk :

gzcat file1.tar.gz | tar xvf -
zcat file2.tar.Z | tar xvf -

^this minus (meanign standard input) is
necessary !!
