Subject: Update shell functionality:


    - Rename OPTIONNAM and OPTIONVAL variable names to ACTIONNAM and
      ACTIONVAL respectively.

    - Inside shell_updateCopyright function, add positional parameters
      interpretation using getopt(1), re-define regular expression to
      match shell files only, define list of files to process.
