 2.8.5 Commands That Will Fail
 -----------------------------
 
 Here are some sample commands you might try which will not work, and why
 they won't work.
 
    If you try to use this command,
 
      $ tar -xvf music.tar folk jazz
 
 you will get the following response:
 
      tar: folk: Not found in archive
      tar: jazz: Not found in archive
 
 This is because these files were not originally _in_ the parent
 directory '..', where the archive is located; they were in the
 'practice' directory, and their file names reflect this:
 
      $ tar -tvf music.tar
      practice/blues
      practice/folk
      practice/jazz
 
 Likewise, if you try to use this command,
 
      $ tar -tvf music.tar folk jazz
 
 you would get a similar response.  Members with those names are not in
 the archive.  You must use the correct member names, or wildcards, in
 order to extract the files from the archive.
 
    If you have forgotten the correct names of the files in the archive,
 use 'tar --list --verbose' to list them correctly.
