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

Challenge: When running commands that produce both standard output (stdout) and standard error (stderr), it can be cumbersome to manage two separate streams of information, especially when trying to capture or process them together.

The Solution: Redirect both stdout and stderr to a single destination, typically a file, using the `2>&1` redirection operator.

your_command &> output.log

Why it works: The `&>` operator is a shorthand for `&>>` which redirects both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified file. This ensures all output from your command, regardless of its origin, is captured in a single log file.

Pro-Tip: You can also achieve this with `your_command > output.log 2>&1`. The order matters here: first redirect stdout to the file, then redirect stderr (file descriptor 2) to where stdout (file descriptor 1) is currently going.
