Tame 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 cumbersome to manage or analyze these streams separately, especially when logging. You often want a consolidated view.

The Solution: Redirecting `stderr` to `stdout` using `2>&1` allows you to capture both output streams into a single destination.

your_command &> output.log

Why it works: The `&>` operator is a shorthand for `&>>` (append) and `2>&1`. It redirects file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout), effectively merging them. This combined stream is then redirected to `output.log`.

Pro-Tip: For appending to the log file instead of overwriting, use your_command >> output.log 2>&1.
