I hope you all are using sitemap.xml for your blog / site if you are not you must start using it because It’s a way that you can point your content to Different Search Engines. Search Engine can sniff your site content via you sitemap (Not all the time.) If you are not having sitemap.xml for your site the you probably get code from Google Code Sitemap Generator.

No we are assuming you are having your own sitemap.xml and you want to update instantly to all major Search Engine on a single click or complete atomized then what will you do ? Just follow the bellow mention steps. Here I am assuming that you have basic knowledge of Programming, Server Handling, FTP etc. I will advice you not to execute / edit wrong file if you are not having proper knowledge of Code or Server Admin. You just do it manually copy the bellow mention code (scripts) edit WWW.YOUR-SITE.COM/SITEMAP.XML to your sitemap URL then paste in browser and hit Enter Key.

This will be manual thing but if you want to make and forgot it thing then what to do? Very Simple You have to  follow following steps. (Make sure you have knowledge of Server Admin)

If you are Using Linux Server

1. Download ping.php file from bellow mention link
2. Edit the file with your sitemap URL.
3. Upload that file in your sites root folder.
4. Now log on to your Control Panel.
5. Find an Option for Create Cron Job
6. Define Cron Job as per your site requirement, Daily, Weekly, Every 1 Hour etc.
7. Select ping.php as schedule file.

If you are using Windows Server then check this:

You can do this in task scheduler of windows server. Task can be created manually in the task scheduler or with @ commands and can be designated to run under a user account with privileges. There is also a software (free) called nnCron which uses the same kind of syntax that of Linux on Windows.
