Use the -f argument for specifying an archive file (or - for
stdin/stdout), see "man tar". If you don't specify a file, then tar will
try to read from a tape device (/dev/nrst0).

Alternatively, use the pax command (see "man pax"), which acts as a
filter by default but uses different command syntax from tar.
