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

Challenge: When running complex commands or scripts, you often have both standard output (stdout) and standard error (stderr) messages, making it difficult to capture and analyze them together, especially when redirecting output to a file.

The Solution: Redirect both standard output and standard error to a single destination using the `2>&1` construct.

your_command > output.log 2>&1

Why it works: The `>` symbol redirects stdout (file descriptor 1) to `output.log`. Then, `2>&1` tells the shell to redirect file descriptor 2 (stderr) to the same place as file descriptor 1 (which is now `output.log`).

Pro-Tip: You can also use `&>` as a shorthand for `&1` on many modern shells (like bash 4+ and zsh) to achieve the same result: your_command &> output.log
