code to update a data group?

Does anyone have a script (Powershell i guess?) that will collect a user input for an IP address/network & mask, append it to an external data group, upload & overwrite the datagroup file and apply it to the F5?

 

 

Well, I guess "have" a script is probably unlikely. Rather, can anyone create one real quick? I know nothing about powershell or programming for the f5's. :-(

 

 

 

 

 

Thanks!
