You should always use the f option to specify the archive - for example
tar -tzf archive.tgz
to list or
tar -xzf archive.tgz
to extract. In your example below, you didn't specify an archive so it
defaulted to the device /dev/sa0, which it couldn't open.
Any extra arguments are treated as archive members - eg
tar -xzf archive.tgz files/to/extract
In your example below, it was trying to find 2 files in a non-existent
archive.
