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

Challenge: When running commands or scripts that produce both standard output (stdout) and standard error (stderr), it can be difficult to manage and analyze the combined output, especially when logging to a file.

The Solution: Use the `2>&1` redirection to merge stderr into stdout.

your_command &> output.log

Why it works: This syntax is a shorthand for `your_command > output.log 2>&1`. The `>` redirects stdout to `output.log`, and `2>&1` then redirects file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout). This ensures all output goes to a single file.

Pro-Tip: You can also use `| tee output.log` to see the output on your terminal *and* save it to a file simultaneously.
