Redirecting `stderr` to `stdout` for Unified Logging

Challenge: When running commands or scripts, you might want to capture both standard output (stdout) and standard error (stderr) into a single log file for easier analysis.

The Solution: Use the `2>&1` redirection operator.

your_command_here &> output.log

Why it works: The `&>` operator is a shorthand that redirects both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified file. This ensures all output, whether normal or error messages, is consolidated.

Pro-Tip: For more granular control, you can explicitly redirect stderr to stdout using `2>&1` after redirecting stdout, like `your_command_here > output.log 2>&1`.
