Quick Tip

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

Challenge: When running commands or scripts that generate both standard output (stdout) and error output (stderr), it can be cumbersome to manage these streams separately, especially when trying to capture all relevant information in a single log file.

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

your_command &> output.log

Why it works: The `&>` is a shorthand that redirects both file descriptor 1 (stdout) and file descriptor 2 (stderr) to the specified file. This ensures all output, whether informational or error-related, is captured in one place.

Pro-Tip: For older shells or for explicit control, you can use `your_command > output.log 2>&1`. The `2>&1` specifically tells the shell to redirect file descriptor 2 (stderr) to the same place file descriptor 1 (stdout) is currently going.
