23.  
24. $md5 $src -size -1024k | sed "s!${src}!${dst}!g" | md5sum -c 2>&1

Get All Files Recursively and Get MD5

1. #!/usr/bin/sh

5. # args: pass all to find

8. for f in $(find $@ -type f);
9. do
10.     md5sum $f
11. done

使用javascript產生guid

參考來源: http://note19.com/2007/05/27/javascript-guid-generator/

javascript

1. function guid() {
2.     function S4() {
3.         return (((1 + Math.random()) * 0x10000) | 0).toString(16).substring(1);
4.     }
5.     return (S4() + S4() + "-" + S4() + "-" + S4() + "-" + S4() + "-" + S4() + S4() + S4());
6. }

html javascript 小時鐘 digit clock

就像這樣:

html javascript

1. <span id="__current_datetime__">
2. <script type="text/javascript">
3.     (function () {
4.         var target = "__current_datetime__";
5.         var padLeft = function(str) {
6.             str = "00" + str;
7.             return str.substring(str.length-2)
8.         };
9.         var getCurrentDateTime = function() {
10.             var d = new Date();
11.             return d.getFullYear() + "&#24180;"
12.                 + padLeft(d.getMonth()+1) + "&#26376;"
13.                 + padLeft(d.getDate()) + "&#26085; "
14.                 + padLeft(d.getHours()) + ":"
15.                 + padLeft(d.getMinutes()) + ":"
16.                 + padLeft(d.getSeconds());
17.         };
18.         var updateCurrentDateTime = function(id) {
19.             document.getElementById(id).innerHTML = getCurrentDateTime();
20.         };
21.         updateCurrentDateTime(target);
22.         setInterval(function() {
23.             updateCurrentDateTime(target);
24.         }, 99);
25.     }) ()
26. </script></span>
