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

Challenge: When running commands or scripts, `stderr` (standard error) and `stdout` (standard output) are often displayed separately, making it difficult to analyze logs or capture all output into a single file.

The Solution: Redirect both `stderr` and `stdout` to the same destination using the `2>&1` syntax.

your_command &> output.log # or equivalently your_command > output.log 2>&1

Why it works: File descriptor `1` represents `stdout`, and `2` represents `stderr`. By redirecting `2` to `1` ( `2>&1`), you’re telling the shell to send error messages to the same place as the standard output. The `&>` shorthand is a convenient way to achieve this redirection to a file.

Pro-Tip: Use `| tee output.log` after your command to see the output on your terminal *and* save it to a file simultaneously.
