Tame Your Terminal: Redirect `stderr` with `2>&1` for Unified Logging

TITLE: Tame Your Terminal: Redirect `stderr` with `2>&1` for Unified Logging

Challenge: When running complex commands or scripts, error messages (stderr) and normal output (stdout) can be interleaved or sent to different locations, making log analysis difficult and cumbersome. You want a way to consolidate both streams into a single, manageable output.

The Solution: Use the `2>&1` redirection operator to send standard error (file descriptor 2) to the same destination as standard output (file descriptor 1).

your_command_here &> output.log

Why it works: The `&>` operator is a shorthand that redirects both stdout and stderr to the specified file. Alternatively, `your_command_here 2>&1 > output.log` achieves the same result by first redirecting stderr to stdout and then redirecting the combined stdout to the file.

Pro-Tip: For more granular control, you can redirect stderr to a separate file using `your_command_here 2> error.log` while stdout goes to `output.log` (without `&1`).
