Speaking is sort of a different animal. “Should of” is a malapropism that is a homophone for “should’ve”. There is no transformation of language from that, it’s just an error. If you accept an alternate written version though, you’re creating an alternate conjugation for the conditional perfect tense. There’s no reason for this at all: it’s accommodating failings of literacy by adding complexity to language rules for one, and creating a new (and faulty) evolution point for two.
It’s like saying “oh, the speed limit is 55, but everyone drives 60, so let’s make the law so the police can’t ticket you unless you go over 60 since 55 or 60 is correct”. What does it mean when you see a sign that says 25 now? You can accept that people break the rules, but that doesn’t mean we should change the rules to describe the situation in every circumstance.
Yeah to me though it was self derivative. It’s not high cinema sure, but I watched episode 4, you don’t have to repeat it with celebrity cameos and better CGI.
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.
