    -x, --extract, --get Extract files from an archive.
    -z, --gzip, --gunzip, --ungzip Filter the archive through gzip(1).
    -j, --bzip2 Filter the archive through bzip2(1).
    -f, --file=ARCHIVE Use archive file or device ARCHIVE.  If this option is not given, tar will first examine the environment variable `TAPE'.  If it is set, its value will be used as the archive  name.   Otherwise, tar will assume the compiled-in default.
