iphone shell - is there any?

[_T1000_]

While working on iphone security architecture, i came to know that i can run applications from other applications in iphone. referring to the following url Launching Other Apps within an iPhone Application

for example, i can put a link in a website with following hyperlink

skype://<phonenumber>

will result skype to run and call at particular number. Now i have few concerns here.

• is there a shell running in background in iphone, so that it allows other application to run basic app commands.
• if the above statement is true then how can i enable or run commands directly into iphone shell?
• if above statements are false, then could you please explain how these commands are being executed?
• is this part of iPhone SDK? or this funcationality is iPhone OS

P.S: my apologies if it is not correct section to post but i found it suitable for this question

I believe you are talking about registered URL schemes.

Check this out : IPhone URL Schemes - akosma wiki

Pretty sure you can register one for your app as well in the info.plist
