\begin{block}{How It Works}
Type command → shell splits on whitespace → runs program with arguments

Prompts vary and are customizable (your \texttt{PS1} controls this).

\begin{exampleblock}<2->{Examples}\label{sec:org4be45af}
\begin{verbatim}
date                    # Show date/time
echo hello              # Print text
echo "Hello World"      # Handle spaces
ls -l ~                # Command with flags
\end{verbatim}
