Which is the advantage of using CakePHP Console / Shell for programmed tasks ?

最近用到了cakephp中的shell,但是不知道为什么要用shell,所以到google了一下，找到了一份比较满意的答案，在这里记录下。
Here are a few reasons that come to mind:
- A shell isn't publicly accessible, where a url (generally) is
- A shell doesn't hit your webserver
- The shell dispatch process has less overhead
- Shell output is easier to log error vs. output
另： Some disadvantages of a web script I can think of are:
- the execution time is limited by the webserver
- the memory it can consume is limited by the webserver
- the script URL has to be protected in order to get executed only when YOU want
- obviously the webserver has to be up and running when you want to call your script
