Hi Tennis,

Perhaps something like this (untested):

(add-hook 'after-change-major-mode-hook
          (lambda ()
             (unless (eq major-mode 'shell-mode)
                (show-ws-highlight-trailing-whitespace))))

Or, if there are several modes that use shell buffers, then use `memq'
instead of `eq'.

Or, turn it on globally and then turn it off in shell mode with
`shell-mode-hook'.

Or...

BTW, although I'm the maintainer of show-ws.el, I recommend you also take a
look at Vinicius Jose Latorre's blank-mode.el:
