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

Challenge: When running commands or scripts that produce both standard output (stdout) and standard error (stderr), it can be difficult to manage and analyze the combined output, especially for logging purposes.

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

your_command &> output.log

Why it works: The `&>` operator is a shorthand for `2>&1 >`, which redirects both file descriptors 1 (stdout) and 2 (stderr) to the specified file. This ensures all output, regardless of its origin, is captured in one place.

Pro-Tip: You can also use `your_command > output.log 2>&1` for the same effect. This explicitly redirects stdout first, then redirects stderr to wherever stdout is currently going.
