A *.tar.gz file needs to be unzipped & then untarred. Previously I might have unzipped first with $gunzip -d file.tar.gz and then untarred the result with $tar -xvf file.tar (Options are extract, verbose, file) Using the -z (decompress) option on tar avoids the use of gzip (or gunzip) first. Additionally the -C option will specify the directory to extract to.
