Are there any command to see how processes are working?

I'm very new to Ubuntu. If I do this sort of command say:

cp file1 file2

The shell creates a child process and that child process will call cp, which in turn call exec system call of operating system.

Are there any command to visualize this process from my terminal?

command-line

  1. strace will show system calls made by a process. It won't give you an instruction-by-instruction view of what happens, but it will give the calls into the kernel performed.

    Just like strace traces the system calls, you can use ltrace to trace library calls.
