The Chezmoi Package is availabe in many package management systems, and that's the ideal install method to avoid manually upgrading via the "--upgrade" flag periodically. Alternatively, you can use the commands below.
Manually Import GPG Key to Fully Complete
gpg --import gpg.key
Install & Apply
sh -c "$(curl -fsLS git.io/chezmoi)" -- init --apply 0x90shell
Apply Then Purge Chezmoi
sh -c "$(curl -fsLS git.io/chezmoi)" -- init --apply --purge --purge-binary 0x90shell
chezmoi update
I am using chezmoi to manage my dotfiles.
This is still very much a work in progress.
