Tame 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 manage and analyze them effectively, especially when scripting or redirecting output to a file.

The Solution: Redirect both standard output and standard error to the same destination simultaneously using the `2>&1` redirection operator.

your_command_here 2>&1 | tee output.log

Why it works: File descriptor 1 represents stdout, and file descriptor 2 represents stderr. The `2>&1` tells the shell to send stderr (file descriptor 2) to wherever stdout (file descriptor 1) is currently going. Combined with `tee`, this ensures all output is visible on the terminal and saved to `output.log`.

Pro-Tip: Use `your_command_here &> output.log` as a shorthand for `your_command_here > output.log 2>&1` to redirect both stdout and stderr to a file.
