I needed quick view option, like in midnight commander, and I wrote this
code.
I want to ask if you know something that already exists and does a
similar job. My code is not complete -- for example, for large files, I
want to see only the header, not to load all the file.
In my emacs this code works as I expect to work. I did not test it
outside -- but it should work as well.

(setq lexical-binding t)
(require 'dired)
(defun qv-update ()
(let ((f (dired-get-filename t t)))
(when (and (stringp f) (file-regular-p f)
(< (nth 7 (file-attributes f)) 1e7))
(when (not (equal (window-buffer)
(save-window-excursion
(window-buffer (other-window 1)))))
(save-window-excursion
(other-window 1)
(and buffer-read-only
(not (buffer-modified-p))
(kill-buffer (window-buffer)))))
(view-file-other-window f)
(other-window 1))))
(defun qv ()
(let ((i 0))
(let ((config (current-window-configuration)))
(delete-other-windows)
(split-window-sensibly)
(balance-windows)
(add-hook 'post-command-hook 'qv-update)
(lambda (message)
(defun exit ()
(setq-local quick-view-object nil)
(define-key dired-mode-map
[(control ?c) (control ?q)]
qv-binding)
(setq i (1- i))
(set-window-configuration config)
(remove-hook 'post-command-hook 'qv-update)
(message "exit qv"))
(apply message '())))))

No GNUs is bad news.
