Tar no longer requires the modifier for the compression when extracting an archive. So no matter if it's a .tar.gz, .tar.Z, .tar.bz2, etc you can just use "tar xvf"

And the same for compression..

    tar caf foo.tar.xz foo/

The extension of the file after the `f` switch tells tar what compression to use.

c - compress

a - auto

by tar you mean gnu tar
