Opinionated dotfiles for *nix based personal and work development environments, managed by Chezmoi.
Requirements:
- Ubuntu (VM, Baremetal or WSL) or MacOS target operating system
- curl installed in target operating system
Run:
sh -c "$(curl -fsLS get.chezmoi.io/lb)" -- init --apply arrrgi [--branch=ref] --use-builtin-git=trueChezmoi runs context/OS specific scripts and applies relevant dotfiles using the high-level logic outlined.

This could be interpreted as the following pseudo-Bash script which minimises the number of nested condition statements by using guard clauses. This aligns closely to the way the Chezmoi base template evaluates conditions, captures necessary inputs from stdin during installation and then executes context and OS specific scripts and config to the target environment.
Additional detail on the conditional logic and inputs required is available in the documentation for this repo.
