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 difficult to manage and analyze the combined output, especially when redirecting to a file or piping to another command.

The Solution: Redirecting both stdout and stderr to a single stream using the `2>&1` syntax.

your_command &> output.log # Or, more explicitly: your_command > output.log 2>&1

Why it works: The `>` redirects stdout (file descriptor 1) to `output.log`. The `2>&1` then redirects stderr (file descriptor 2) to wherever stdout is currently being redirected (which is `output.log` in this case).

Pro-Tip: Use `&>` as a shorthand for `> file 2>&1` for more concise redirection.
