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

Challenge: When running complex commands or scripts, important error messages (sent to stderr) can get lost amidst standard output (stdout), making debugging and log analysis difficult.

The Solution: Redirect both standard error and standard output to a single file for consolidated logging using the `2>&1` redirection operator.

your_command &> output.log

Why it works: The `&>` operator is a shorthand for `> file 2>&1`. It redirects both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified file (`output.log` in this case), ensuring all output is captured in one place.

Pro-Tip: For older shells or if you prefer explicit redirection, you can use your_command > output.log 2>&1. The order matters: stdout is redirected first, then stderr is redirected to where stdout is currently pointing.
