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

Challenge: When running commands or scripts, you often see error messages (stderr) and standard output (stdout) mixed together, making it difficult to analyze the results or redirect them to a file. This is especially true when debugging.

The Solution: Redirect both standard error (file descriptor 2) and standard output (file descriptor 1) to a single destination using `2>&1`.

your_command &> output.log # or your_command > output.log 2>&1

Why it works: The `&>` operator is a shorthand for redirecting both stdout and stderr. Alternatively, `> output.log 2>&1` explicitly redirects stdout to `output.log` and then redirects stderr to the same place as stdout. This consolidates all output into a single, manageable file.

Pro-Tip: Use `| tee output.log` after your command to see the output on your terminal AND save it to a file simultaneously.
