I want to use simics via a shell script

I mean what I am actually wanting to see if there is a way to run simics like this:

simics file.ext

where file.ext is a file which has the commands that i can execute

Or if I could just write a bash shell script to do it

I have a proj. in my mind but i need to execute shell commands in the target system just like we can do it in Docker
I mean I f you have used docker there is this cmd:
docker exec <container name> <command> where I can execute a command in the target system without actually entering into the system console
I want to do a similar thing using simics

Doing an ssh into the target system is one way but otherwise is there anything else??
