Dotfiles

It is possible that you have multpile machines and you want to have same configuration on all of them. This is where dotfiles come in. Dotfiles are configuration files that are hidden and start with a dot. These files (if there are no saved passwords) can be stored in a git repository and can be cloned on any machine.

Creating Dotfiles Repository

This is a simple way to create a dotfiles repository. There are other ways to do this. This is just one way to do it. I am assuming the you have dot files for zsh and tmux. If you have other dotfiles, you can create a folder for that as well.

1. Install stow brew install stow
2. Create a git repository on github called dotfiles
3. Clone the repository to your local machine git clone <repo-url>
4. Change directory to dotfiles cd ~/dotfiles
5. For Shell
   1. Create a folder called shell mkdir shell
   2. Change directory to shell cd shell
   3. Move the zshrc file to shell folder mv ~/.zshrc .
   4. Move p10k.zsh to shell folder mv ~/.p10k.zsh .
   5. Move to dotfiles folder cd ..
   6. Create a symlink for zshrc stow shell
6. For Tmux
   1. Create a folder called tmux mkdir tmux
   2. Change directory to tmux cd tmux
   3. Move the tmux.conf file to tmux folder mv ~/.tmux.conf .
   4. Move to dotfiles folder cd ..
   5. Create a symlink for tmux stow tmux
7. Add and commit the changes git add . && git commit -m "Basic dotfiles setup"
8. Push the changes to a remote repository git push

Reusing the Dotfiles repository on a new machine

1. Install stow brew install stow
2. Clone the dotfiles repository git clone <repo-url>
3. Change directory to dotfiles cd ~/dotfiles
4. Create a symlink for zsh stow shell
5. Create a symlink for tmux stow tmux
