I always learned that .tgz meant the file was created via "tar czf
..." while tar.gz meant the file was a tarball that was compressed
("tar cf - | gzip -9"; "tar cf file.tar ... && gzip -9 file.tar",
etc.)
Note that it's not quite the same:
[EMAIL PROTECTED]:~ $ tar czf test.tgz drm
[EMAIL PROTECTED]:~ $ tar cf - drm | gzip -9 > test.tar.gz

-rw-rw-r-- 1 nnorman nnorman 155636 Sep 13 14:54 test.tgz
Of course both files can be read via "tar zxf" or "zcat file | tar x",
so my point (if there is one :) is that tarring then compressing is
more efficient.
