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 and view these messages separately, especially when redirecting output to files or pipes.

The Solution: Redirect both stdout and stderr to a single stream 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. Alternatively, you can use `your_command > output.log 2>&1` which explicitly redirects stdout to `output.log` and then redirects stderr (2) to wherever stdout (1) is currently going.

Pro-Tip: For interactive debugging, you can use `your_command 2>&1 | tee output.log` to see the combined output on your terminal while also saving it to a file.
