I've used my custom bash script for managing dotfiles for ages and also have tried all other tools, but just couldn't get it right because I work on multiple OS. Then I found https://github.com/rhysd/dotfiles https://github.com/rhysd/dotfiles. It is the only tool I know of that can support multiple OS (Linux, mac, windows). I have to work with multiple OS and having a single dotfiles repo has been great, especially its ability to set different config on different OS, well as a unified Unix-like config setting.
