Quick Tip

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

Challenge: When running commands that produce both standard output (stdout) and error messages (stderr), it can be difficult to track both simultaneously, especially when redirecting output to a file or piping it to another command.

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

your_command &> output.log

Why it works: This redirection redirects file descriptor 2 (stderr) to file descriptor 1 (stdout). When combined with `&>` (which is shorthand for `> … 2>&1`), it effectively merges both streams into a single output file, `output.log` in this case.

Pro-Tip: You can also use `your_command > output.log 2>&1` for the same effect, explicitly redirecting stdout first and then stderr to where stdout is going.
