How do I prevent repeated commands from being saved in the OS X terminal?

Question

terminal emulator

Actually, I would like that when scrolling through the executed commands, only unique commands are displayed, and not all that have been executed.
That is, if I typed "ssh 123.45.67.89 -l root" 10 times, I would like to see this command only 1 time.
Thanks in advance.
