Just that it would be `.zshrc` since zsh is already the default shell in the context of this post unless you enjoy a mid-2000s existence and none of the nice bash features of this generation (in which whatever `.bashrc` you've crafted is likely broken by time passing).

Maybe I'm underinformed, but I don't personally know any Linux users who convert to zsh, instead opting for fish or something else (oilsh? nushell?).
