        $ tar -cavvf archive.tar.gz [FILES]

        $ tar -cvvf archive.tar [FILES]

Then, compress the tarball:

        $ gzip archive.tar

If many files (a few hundred) are to be archived in a tarball and need to be compressed, we use the second method with a few changes. The problem with defining many files on the command line is ...
