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 the combined information, especially for logging purposes.

The Solution: Redirect both stdout and stderr to a single file or stream using the `2>&1` syntax.

your_command &> output.log # or your_command > output.log 2>&1

Why it works: File descriptor 1 (stdout) and file descriptor 2 (stderr) are standard. By redirecting descriptor 2 to where descriptor 1 is currently going (`>&1`), both streams are sent to the same destination. The `&>` shorthand is a convenient Bash feature for this redirection.

Pro-Tip: Use `tee` to view the output in real-time while also saving it to a file: your_command | tee output.log.
