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

Challenge: When running commands or scripts, error messages (stderr) and standard output (stdout) are often interleaved, making it difficult to analyze logs or capture both streams cleanly.

The Solution: Redirect stderr to stdout using the `2>&1` operator.

your_command &> output.log

Why it works: The `&>` operator is a shorthand that redirects both stdout and stderr to the specified file. This ensures all output, whether informational or error-related, is captured in a single, manageable log file.

Pro-Tip: You can also use `your_command 2>&1 | tee output.log` to both redirect to a file and see the output on your terminal simultaneously.
