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

Challenge: When running commands or scripts that produce both standard output (stdout) and error output (stderr), it can be difficult to analyze them together, especially when redirecting output to a file or piping it to another command.

The Solution: You can redirect both stdout and stderr to the same destination using the `2>&1` construct.

your_command_here > output.log 2>&1

Why it works: File descriptor 1 represents stdout, and file descriptor 2 represents stderr. The `2>&1` tells the shell to redirect file descriptor 2 (stderr) to the same place as file descriptor 1 (stdout).

Pro-Tip: For simpler redirection where you only want to send both to stdout, you can often just use `> output.log` if the command’s stderr is less critical, or more explicitly redirect stderr to a file with `2> error.log` if you need them separated.
