Just this morning my oldest daughter who is almost 4 asked me to go to the basement before school and I said I would turn on the light and get it ready for her, but Daddy wanted to say for a few minutes on the couch.
She said “Ok dad, here’s bun bun (her comfort animal) so you can snuggle and feel better”. It was so selfless I went with her anyway and she said “Did you know I love you, dad?” On the way down the stairs and it was great.
But she was totally emotionally intelligent enough to say “daddy isn’t feeling good, I’d like to help him” and I think that starts MUCH earlier than people think.
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.
