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

Challenge: When running commands or scripts, you often want to capture both standard output (stdout) and standard error (stderr) into a single log file for easier analysis. By default, these go to different destinations.

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

your_command > output.log 2>&1

Why it works: This command redirects stdout to `output.log` (`> output.log`) and then redirects file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout) (`2>&1`). This ensures all output, including errors, ends up in the specified log file.

Pro-Tip: For more complex scenarios, consider using `tee` in conjunction with `2>&1` to simultaneously view output on the terminal and save it to a log file: your_command | tee output.log 2>&1
