Dotfiles
Your shell's config (.zshrc)
Hidden setup files (names starting with a dot, like .zshrc or .bashrc) that customize your shell — aliases, your prompt, your PATH — loaded every time a terminal opens.
Concrete example
Add an alias like gs=“git status” to your .zshrc and “gs” becomes shorthand from then on.
