Quick Tip

Tame Your Terminal: Redirecting `stderr` with `2>&1`

Challenge: When running commands that produce both standard output and error messages, it’s often useful to consolidate them into a single log file for easier analysis.

The Solution: Use the `2>&1` redirection operator.

your_command &> output.log

Why it works: The `&>` operator is a shorthand that redirects both standard output (file descriptor 1) and standard error (file descriptor 2) to the specified file. This ensures all command output, regardless of its origin, is captured.

Pro-Tip: If you only want to redirect standard error and keep standard output on the terminal, use `your_command 2> error.log` or `your_command 2>&2` to duplicate stderr to stdout.
