Shell Commands | Intro to the CLI Part 2

Part two of a command-line introduction explains core shell concepts for navigating and managing a computer’s file system. It covers identifying the current user with `whoami`, locating the present working directory with `pwd`, viewing directory contents through `ls` and its options, and changing locations with `cd`, including relative paths, home-directory shorthand, and previous-directory navigation. The material also introduces creating directories and files with `mkdir` and `touch`, moving, renaming, copying, and deleting files with `mv`, `cp`, and `rm`, emphasizing the risks of permanent deletion and root-level access. It encourages users to consult built-in documentation with `man`, describes useful commands for clearing screens, viewing command history, inspecting processes, and reading files, and highlights keyboard shortcuts such as command-history search, interruption, and tab completion.
