dotfiles

A collection of my personal *NIX configuration files, used in macOS.

The dotfiles contained within this version-controlled directory lack the usual "." prefix as they are symlinked into the $HOME directory using the bashdot tool. When the symlinks are created in the $HOME directory, it automatically prefixes them with a dot.

.bootstrap.sh was previously used to copy dotfiles into the $HOME directory and is now kept as a backup. It is prefixed with a dot to hide it from the bashdot tool.

Symlink files in version-controlled directory to $HOME

The dotfiles directory must be in $HOME.

cd "$HOME"
bashdot install dotfiles

To set the complete path that shells open with for a profile in Terminal, without changing the system-wide default:

1. Terminal --> Preferences --> General
2. Under Shells open with, set the Command (complete path) to /opt/homebrew/bin/bash
