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

Challenge: When running commands or scripts, error messages (stderr) and standard output (stdout) often get mixed or appear separately, making log analysis and debugging difficult.

The Solution: Redirect both stderr and stdout to a single location using the `2>&1` redirection operator.

your_command_here &> output.log

Why it works: The `&>` syntax is a shorthand for `> output.log 2>&1`. It redirects stdout (file descriptor 1) to `output.log` and then redirects stderr (file descriptor 2) to wherever stdout is currently being sent (which is `output.log`).

Pro-Tip: You can also use `your_command_here > output.log 2> error.log` to send stdout and stderr to separate files.
