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

Challenge: When running commands or scripts, standard output (stdout) and standard error (stderr) are often interleaved or sent to different destinations, making it difficult to capture and analyze all messages together, especially during debugging or log aggregation.

The Solution: Redirecting standard error to standard output using `2>&1` allows you to treat both streams as one.

your_command &> output.log

Why it works: The `&>` operator is a shorthand in bash for redirecting both stdout and stderr to the specified file. The `2` represents stderr, `>` is the redirection operator, and `1` represents stdout. Thus, `2>&1` means “redirect file descriptor 2 (stderr) to the same place as file descriptor 1 (stdout).”

Pro-Tip: Use `your_command > output.log 2>&1` if you prefer explicit redirection and want to ensure portability with shells that might not support the `&>` shorthand.
