Taming Terminal Noise: Unified Logging with `2>&1`

Challenge: When running commands that produce both standard output (stdout) and error output (stderr), you often want to combine them into a single stream for easier analysis or logging.

The Solution: Redirect stderr to stdout using the `2>&1` redirection operator.

your_command &> output.log

Why it works: The `&>` operator is a shorthand for redirecting both stdout and stderr to a specified file. Alternatively, you can explicitly redirect stderr (file descriptor 2) to stdout (file descriptor 1) using `2>&1` after redirecting stdout.

Pro-Tip: Use `your_command > output.log 2>&1` if you specifically want to append to the log file instead of overwriting it.
