Execute Instruments/Automations via ShellScript

[Neo1989]

Hello,
i would like to do my UI Test automatically after build my Iphone App via xCode.

Atm i use a Hudson job with shellscript to build my app and after that i would like so start Instruments/Automation with my app as target and my script.
After the test there should be the log of Instruments/Automation in a file.

cd objectivec/my-app-project
xcodebuild -target "my-app-project" -configuration "Debug" -sdk iphoneos3.2
----
start Instruments/Automation -target myapp.app -script mytestscript.js -log into log.text

Is there any possibility to do this?
