RE: Using the -N options in gzip

[Respass, Clarence (EHQ)]

It looks like we are not using the latest version, but there is a lot of red 
tape involved to get the software upgraded.

gzip 1.3.5 (HP-UX fixlevel 1)

Please do the following:
  - tell us what version of gzip you're using on your Unix system (--version)
  - if it's not the latest (gzip-1.4), consider upgrading first
  - tell us what type of system your using (version, kernel)
  - attach a sample file and demonstrate the precise commands you use
      and show the output they produce

E.g.,

    $ echo foooooooooooo > k.txt
    $ gzip --list k.txt.gz                                                      
 :
             compressed        uncompressed  ratio uncompressed_name
                     30                  14 114.3% k.txt
    $ gzip -Nvd k.txt.gz                                                        
 :
    k.txt.gz:       114.3% -- replaced with k.txt
