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

Challenge: When running commands or scripts, you often need to capture both standard output (stdout) and standard error (stderr) into a single log file for comprehensive analysis.

The Solution: Redirecting stderr to stdout using `2>&1` is a common and effective shell technique.

your_command &> output.log

Why it works: The `&>` operator is a shorthand for redirecting both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified file. This ensures all output, including error messages, ends up in your log file.

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