Fork() is how you create new processes in Unix. When you call fork , you're creating a copy of your own process that has its own address space. This allows multiple tasks to run independently of one another as though they each had the full memory of the machine to themselves.
Fork() in C. Fork system call is used for creating a new process, which is called child process, which runs concurrently with the process that makes the fork() call (parent process).
When a process calls fork, it is deemed the parent process and the newly created process is its child. After the fork, both processes not only run the same program, but they resume execution as though both had called the system call.
There is not really one executing before the other. It is simply that the parent will fork() then wait() for the child to complete. It may even fork several times if you use a piped series of commands for instance.
RETURN VALUE Upon successful completion, fork() returns 0 to the child process and returns the process ID of the child process to the parent process. Otherwise, -1 is returned to the parent process, no child process is created, and errno is set to indicate the error.
