So you can do what you like, but if you are going down the road of shell customization, I recommend you first consider if bash is the shell you want to keep by googling around and reading some articles.
I personally use ZSH (and I cannibalized ohmyzsh for the few configs I wanted instead of taking the whole giant bastard of a thing) but fsh is a fine choice if you don’t care about posix (a different discussion). There are some other options to consider as well, but if you’re gonna configure, don’t do it then do it again in a month with different syntax lol.
My 3 yo told me tonight when I had her pacifier that it wasn’t for me, only for her and her little brother not mommy and daddy. Then I said what about the dog? And she told me the dog doesn’t like a paci because she doesn’t have big lips.
