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

Challenge: When running commands that produce both standard output (stdout) and standard error (stderr), it’s often useful to capture both streams into a single log file for easier analysis.

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

your_command > output.log 2>&1

Why it works: The `>` operator redirects stdout (file descriptor 1) to `output.log`. The `2>&1` then redirects stderr (file descriptor 2) to the same place where stdout is currently being redirected (file descriptor 1).

Pro-Tip: For more complex scenarios, using `&>` (Bash 4+) is a shorthand for `&1`. For example: your_command &> output.log
