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

Challenge: When running commands or scripts, error messages (stderr) and regular output (stdout) are often displayed separately, making it difficult to capture and analyze all output in one place.

The Solution: Redirect both standard error (stderr) and standard output (stdout) to a single file or pipe 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 equivalent to `your_command > output.log 2>&1`.

Pro-Tip: You can also use `tee` in conjunction with `2>&1` to view the output on the terminal *and* save it to a file simultaneously: your_command &> >(tee output.log)
