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

Challenge: When running commands or scripts that produce both standard output (stdout) and error messages (stderr), it’s often desirable to capture both in a single log file for easier analysis.

The Solution: Use shell redirection with `2>&1` to combine stderr with stdout.

your_command &> output.log

Why it works: The `&>` operator is a shortcut that redirects both stdout and stderr to the specified file. This ensures all output from your command, including errors, is logged in one place.

Pro-Tip: For older shells or when you need explicit control, you can use `your_command > output.log 2>&1`. The `2>&1` part specifically tells the shell to send file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout).
