bash – How to automatically open the linux terminal window in a certain position on ubuntu

Firstly, I know there are a few similar questions to mine at the moment; I’ve already checked them but did not really find a solution.

I saw this line very often: gnome-terminal --geometry 30x30+100+0, and yes, it almost does what I want, BUT, here’s the point: This command OPENS A NEW WINDOW with the specified size, and I put it on my .bashrc and blew everything up by getting infinitely-opening terminal windows… whoops 😀

Here’s my question, how can I get the terminal position open as I like every time I press the terminal icon or try to open it with any shortcut possible PERMANENTLY (of course without having to deal with an infinite loop)?
Am I supposed to type something in a certain path?

I’m using the latest version of ubuntu.
