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

Challenge: When running commands or scripts, error messages (stderr) and standard output (stdout) are often displayed separately, making it difficult to capture and analyze all output in a single log file.

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

your_command &> output.log

Why it works: The `&>` operator is a shorthand for `2>&1 > output.log`. It redirects file descriptor 2 (stderr) to file descriptor 1 (stdout), and then redirects file descriptor 1 (which now contains both stdout and stderr) to the specified file `output.log`.

Pro-Tip: For older shells or if you prefer explicit redirection, you can use your_command > output.log 2>&1.
