managing-chezmoi

You can manage dotfiles across multiple machines using chezmoi by adding your configuration files to a source directory, then applying them to target directories to ensure consistent system configuration across different environments.

The best way to apply dotfile changes to a new system with chezmoi is to use the apply command, which reads your source state and updates the target directories to match your preferred editor, shell, and application configurations.

Chezmoi templating works by using Go templates within your source dotfiles, allowing you to generate dynamic configurations that adapt based on machine-specific data, environment variables, or conditional logic during the application process.

Chezmoi might not apply a dotfile if ignore rules are configured to exclude it, or if there is a mismatch in the source-target model that prevents the file from being written to the target directory.

You can diff the current state of your dotfiles against the chezmoi source state by running the diff command, which displays the changes that would be applied to your target files without actually modifying them.

Yes, you need to understand the chezmoi source-target model to troubleshoot configuration issues, as it forms the basis for tracking file states, resolving templating errors, and diagnosing why changes are not applying correctly to your system.
