In Unix-like operating systems, dotfile is synonymous with hidden file. Usually used by programs to store configuration variables.

I have multiple machines, which I regularly work on. I keep sync of a set of personalized dotfiles between them – customized settings for programs that I’m using, like many of you. Till now, I was using my private git repository for things like my private scripts, Mutt, Irssi, Ekg2 or Tmux configurations. On the other hand some I keep publicly available for others i.e. on GitHub like Vim configs. And oh boy, there are so many of them! The true is, I customize almost everything that I’m using including simple tools like cp (just to get progress bar or interactivity).
