;; write a command that moves a file in a website, to another dir

;; suppose u need to move the file named a/x.html to ../b/x.html
;; need to be sure the file do not already exist in the new dir.

;; two things u need to do
;; 1. change all links in the file x.html, so they still work
;; 2. go thru all files in your domain dir, check every file that has link to x.html, change all the links

;; suppose we want to move
;; c:/Users/xah/web/xahlee_info/js/css_2d_transform.html
;; to the dir
;; c:/Users/xah/web/xahlee_info/css/

;; how to change the link

;; find all html tags that contains a link. examples
;; <link rel="stylesheet" href="../lbasic.css" />
;; <a href="index.html">
;; <img src="i/alice-cheshire.png" alt="Cheshire cat" width="432" height="626" />

;; secondly, for each link path, there are many variations
;; <a href="index.html">
;; <a href="./index.html">
;; <a href="../index.html">
;; <a href="../i/index.html">
;; <a href="http://xahlee.info/index.html">
