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

Challenge: When running commands or scripts, you often want to capture both standard output (stdout) and standard error (stderr) into a single log file for easier analysis. By default, these are directed to separate streams.

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

your_command &> output.log

Why it works: The `&>` operator is a shorthand that redirects both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified file. This is a concise way to ensure all output, including error messages, is captured in one place.

Pro-Tip: For more granular control or to redirect stderr to a different file, you can use `your_command > output.log 2> error.log`.
