Whenever a command is issued in Unix/Linux, it creates/starts a new process. For example, pwd, when published, is used to list the current directory location the user is in, and a process begins.

How do you create a process in Unix?

A new process can be created by the fork() system call. Split () begins a new process from the existing process. The new process consists of a copy of the address space of the original process.
