Quick Tip

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

Challenge: When running commands or scripts that produce both standard output (stdout) and error output (stderr), it can be difficult to manage and analyze them separately, especially when trying to capture all output for logging or debugging purposes.

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

your_command &> output.log

Why it works: The `&>` operator is a shorthand for redirecting both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified file. This ensures that all output, including errors, is captured in a single log file.

Pro-Tip: You can also achieve this more explicitly with `your_command > output.log 2>&1`. The order is important here; `2>&1` must come after `> output.log`.
