What system calls have to be executed by a command interpreter or shell
in order to start a new process?
Answer: In Unix systems, a fork system call followed by an exec system
call need to be performed to start a new process. The fork call clones the
currently executing process, while the exec call overlays a new process
based on a different executable over the calling process.
