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

TITLE: Tame Terminal Noise: Unified Logging with `2>&1`

Challenge: When running complex commands or scripts, you often get both standard output (stdout) and standard error (stderr) messages interleaved, making it difficult to parse or log effectively.

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

your_command ... > output.log 2>&1

Why it works: The `> output.log` redirects stdout to the file `output.log`. The `2>&1` then redirects file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout), which is already redirected to `output.log`.

Pro-Tip: Use this when running long-running processes in the background with `nohup` to ensure all output is captured in a single log file.
