Is there a command that allows me to have my cursor switch windows to a specified buffer? Something that looks like
(switch-to-specific-window-command "buffer-name")

Command switch-to-buffer, bound to C-x b, does what you're looking for. Likewise, switch-to-buffer-other-window, bound to C-x 4 b, and switch-to-buffer-other-frame, bound to C-x 5 b.
Command pop-to-buffer also does what you request, slightly differently.
From your comments, it's not clear what you want. The goalposts seem to be moving...
Now you seem to say you want to do nothing if the buffer is already in the selected-window? In that case, pop-to-buffer does just what you want, I think. Have you tried it?
Or if you don't want to use pop-to-buffer, but that is anyway what you want (do nothing if already visiting the buffer in the selected window), then this does that also:
(defun foo (buffer)
(interactive "b")
(unless (equal (get-buffer buffer) (window-buffer (selected-window)))
(switch-to-buffer-other-window buffer)))

This would switch to the buffer in the current window. But what I would like to do is to go to the window that already is visiting buffer that I am specifying – Tian Nov 13 '21 at 17:56

1No. `pop-to-buffer` uses another window, as does `switch-to-buffer-other-window` (`C-x 4 b`). – Drew Nov 13 '21 at 19:05

Sorry for the misunderstanding. I meant that `switch-to-buffer` would behave in the manner I stated in my comment. `switch-to-buffer-other-window` would not do the job, as if lets say i was already in the window of the buffer that i wanted to switch to. it would switch to another window and open that buffer there. What I want is for a function that would go to that already open window, regardless of whichever window is in focus – Tian Nov 13 '21 at 19:37

2If you haven't tried `pop-to-buffer`, please try it. If you *have* tried it, in what way does it fall short? – NickD Nov 14 '21 at 00:45
