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

Challenge: When running commands or scripts, error messages (stderr) and normal output (stdout) are often mixed, making log analysis or redirection difficult.

The Solution: Redirect both standard error and standard output to a single location.

your_command &> output.log

Why it works: The `&>` operator is a bash shorthand that redirects both stdout and stderr to the specified file. If you need more granular control or are using a different shell, `2>&1` achieves the same goal by redirecting file descriptor 2 (stderr) to file descriptor 1 (stdout).

Pro-Tip: To append to the log file instead of overwriting it, use `>>` instead of `>` in your redirection, e.g., `your_command &>> output.log`.
