Quick Tip

Tame 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 cumbersome to manage and analyze two separate streams of information, especially when trying to redirect them to a single log file.

The Solution: Use the `2>&1` redirection operator to merge stderr into stdout.

your_command &> output.log

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

Pro-Tip: For more granular control, you can explicitly redirect stderr to stdout first (`2>&1`) and then redirect stdout to a file (`> your_log_file.log`). For example: `your_command 2>&1 > your_log_file.log`
