Shell and Other Basics

The shell is a command-line interface that allows users to interact with the Linux operating system. It interprets user commands and executes them.

📄️ Command Path

Every Linux command is stored in a specific directory.

Environment variables store system and user information used by the shell.

Linux provides built-in help for commands to understand their usage and options.

Redirection allows input and output of commands to be sent to files instead of the screen.

The superuser (also called root) has full control over the system.
