Silence the Noise: Unified `stderr` and `stdout` Logging

Challenge: When running commands or scripts, error messages (sent to stderr) and normal output (sent to stdout) can get mixed up, making log analysis and troubleshooting difficult.

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

your_command_here &> output.log # Or your_command_here 2>&1 | tee output.log

Why it works: File descriptor `2` represents stderr, and `&1` represents stdout. By redirecting `2` to `1` (or a file associated with `1`), both streams are merged. The `&>` operator is a shorthand for this redirection to a file.

Pro-Tip: Use `| tee output.log` after `2>&1` to see the output on your terminal in real-time while simultaneously saving it to a file.
