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 capture and analyze both streams simultaneously, especially for logging or redirection purposes.

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

your_command > output.log 2>&1

Why it works: The `>` operator redirects stdout (file descriptor 1) to `output.log`. The `2>&1` then redirects stderr (file descriptor 2) to the same place stdout is currently directed (which is `output.log`).

Pro-Tip: For even more flexibility, you can use `tee` to both display output on the terminal and write it to a file: your_command | tee output.log 2>&1
