So, I just found out about a programme called SynthShell which kind of does the work for you and gives you a nice looking shell, the thing is that this also creates some config files and other stuff in my system, instead of just one .bashrc file to edit. What would be the best way to learn to have a nice looking bash where I can just have a backup of it that I can use throughout systems?
chezmoi.io is one of the best dotfile managers available. Great template language if you need different, many ways to distribute secrets safely, merging works well even with templates, not limited to homedir.
