Not one-liners, but some of the tools that I have found helpful for working with large bash codebases are:

  - shellcheck and shfmt for linting and formatting
  - sub for organizing subcommands
  - bashdb for debugging scripts interactively via the VSCode extension

I'm still missing a way to share modules with others like it can be done with ansible/terraform, but I have not found an optimal way to do it yet.
