Hidden files: the dot convention

Here's a Unix rule that surprises newcomers: any file whose name starts with a dot is "hidden", so a plain ls won't show it. Nothing is encrypted or locked; it's just a quiet convention for configuration that shouldn't clutter everyday listings. Crucial dotfiles are everywhere: a project's .gitignore, a shell's .bashrc, an app's .env.local.

ls -a lists all entries, hidden ones included. Flags combine, so ls -la gives you the long format with the hidden files too.

The habit to build: when something "isn't there" but should be, it's often just hidden. This directory has exactly such a file, waiting for you to uncover it.
