Hey there,

Are you trying to extract the archive? If so, you need to change the command to to extract it. You could also run it without the "-" like this: & it will work just as well. What's happening here is as follows: The x option tells tar to extract the archive. The v option tells tar to print the filename currently being extracted (or being put into a tar archive) to the console. The f option specifies the filename that tar needs to work with, & is used when both extracting & creating tar archives. The z option shouldn't be necessary here being I think it only applies when creating a tar archive (the z option runs the archive through the gzip compressor). Hopefully this clears things up for you.
