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

Challenge: When running commands that produce both standard output (stdout) and standard error (stderr), it can be difficult to capture and analyze both streams effectively, especially for logging or debugging purposes.

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

your_command_here > 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 location as stdout (file descriptor 1), effectively merging both streams into one.

Pro-Tip: For only capturing stderr, you can use `your_command_here 2> error.log`.
