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

Challenge: When running commands or scripts that produce both standard output (stdout) and error output (stderr), it can be difficult to manage and analyze them separately. This often leads to cluttered logs or missed critical error messages.

The Solution: Redirect both stdout and stderr to a single destination, typically a file, by using the `2>&1` redirection operator.

your_command &> 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 erroneous, is captured in one place for easier review.

Pro-Tip: You can also achieve this with `your_command > output.log 2>&1` for explicit redirection of stdout to the file, then stderr to wherever stdout is currently going (which is the file in this case).
