 The `--verbose' Option
 ----------------------
 
 `--verbose'
 `-v'
      Show the files being worked on as `tar' is running.
 
    `--verbose' (`-v') shows details about the results of running `tar'.
 This can be especially useful when the results might not be obvious.
 For example, if you want to see the progress of `tar' as it writes
 files into the archive, you can use the `--verbose' option.  In the
 beginning, you may find it useful to use `--verbose' at all times; when
 you are more accustomed to `tar', you will likely want to use it at
 certain times but not at others.  We will use `--verbose' at times to
 help make something clear, and we will give many examples both using
 and not using `--verbose' to show the differences.
 
    Sometimes, a single instance of `--verbose' on the command line will
 show a full, `ls' style listing of an archive or files, giving sizes,
 owners, and similar information.  Other times, `--verbose' will only
 show files or members that the particular operation is operating on at
 the time.  In the latter case, you can use `--verbose' twice in a
 command to get a listing such as that in the former case.  For example,
 instead of saying
 
      tar -cvf afiles.tar apple angst aspic
 
 above, you might say
 
      tar -cvvf afiles.tar apple angst aspic
 
 This works equally well using short or long forms of options.  Using
 long forms, you would simply write out the mnemonic form of the option
 twice, like this:
 
      $ tar --create --verbose --verbose ...
 
 Note that you must double the hyphens properly each time.
 
    Later in the tutorial, we will give examples using
 `--verbose --verbose'.
