Why should I use a dotfile manager?
Dotfile managers give you the combined benefit of a consistent environment everywhere with an undo command and a restore from backup.As the core of our development environments become increasingly standardized (e.g. using git at both home and work), and we further customize them, at the same time we increasingly work in ephemeral environments like Docker containers, virtual machines, and GitHub Codespaces.
I already have a dotfile system, why should I use chezmoi?
What users say
Fast machine setup with secrets management
Fast machine setup with secrets management
I’ve been using Chezmoi for more than a year now, across at least 3 computers simultaneously, and I really love it. Most of all, I love how fast I can configure a new machine when I use it. In just a couple minutes of work, I can kick off a process on a brand-new computer that will set up my dotfiles and install all my usual software so it feels like a computer I’ve been using for years. I also appreciate features like secrets management, which allow me to share my dotfiles while keeping my secrets safe. Overall, I love the way Chezmoi fits so perfectly into the niche of managing dotfiles. — @mike_kasberg
More complex than it first appears
More complex than it first appears
I had initially been turned off when I first encountered [chezmoi], because [chezmoi] seemed overkill for (what appeared to me) a simple task. But the problem of managing a relatively small number of dotfiles across a relatively small number of machines with small differences between them and keeping them up to date proved to be MUCH more complex than I imagined. Copy things around by hand, and then later distributing them via source control got hairy very quickly. I finally realized all those features were absolutely necessary to manage things sanely, and once I took some time to learn how to do things with chezmoi, I have never looked back. — njt

Common problems chezmoi solves
If you’re using any of the following methods, you’ve probably encountered these issues:- A custom shell script
- An existing dotfile manager like dotbot, rcm, homesick, vcsh, yadm, or GNU Stow
- A bare git repo approach
Managing differences between machines requires extra effort
Without chezmoi
- Manually perform extra steps for each machine
- Run different commands on different machines
- Maintain separate per-machine files or branches
- Deal with merge conflicts and rebasing
- Hope custom logic handles differences correctly
With chezmoi
- Single source of truth (one branch)
- Single command works on every machine
- Templates handle machine-to-machine differences
- Predefined variables for OS, architecture, hostname
Keeping your dotfiles repo private
And regarding dotfiles, I saw that. It’s only public dotfiles repos so I have to evaluate my dotfiles history to be sure. I have secrets scanning and more, but it was easier to keep it private for security, I’m ok mostly though. I’m using chezmoi and it’s easier now — @sheldon_hull
With chezmoi you can store secrets in your password manager or encrypt them, and even store passwords in different ways on different machines. You can clone your dotfiles repository anywhere, and even make your dotfiles repo public, without leaving personal secrets on your work machine or work secrets on your personal machine.
Maintaining your own tool
Custom shell script
I’ve offloaded my dotfiles deployment from a homespun shell script to chezmoi. I’m quite happy with this decision. — @gotgenes
Migration experience
I discovered chezmoi and it’s pretty cool, just migrated my old custom multi-machine sync dotfile setup and it’s so much simpler now in case you’re wondering I have written 0 code — @buritica
Chezmoi is like what you might get if you re-wrote my bash script in Go, came up with better solutions than diff for managing config on multiple machines, added in secrets management and other useful dotfile tools, and tweaked and perfected it over years.
— @mike_kasberg
If your system was written by you for your personal use, then it probably has the functionality that you needed when you wrote it. If you need more functionality then you have to implement it yourself.
- Dry-run and diff modes
- Script execution
- Conflict resolution
- Windows support
- Template functions
- Password manager integration
- File encryption
- And much, much more
Setting up dotfiles requires more than one command
