Is it possible to create a new process via fork mechanism in Go language?

The Go language does not have a built-in fork mechanism like in Unix-like systems at the system call level. Go is oriented towards using goroutines for concurrent execution and provides the os/exec package for launching new processes.

If you need to create a new process, you typically use exec.Command to run an external program rather than fork the current process.

Example of launching a new process:

cmd := exec.Command("ls", "-la")
output, err := cmd.Output()
if err != nil {
    log.Fatal(err)
}
fmt.Println(string(output))

Thus, the fork operation as in C or Unix API is not directly used in Go; instead, new processes are launched via exec or concurrency is achieved through goroutines.
