Taming 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 the combined output, especially when redirecting to a file or piping to another command.

The Solution: Redirect standard error to standard output using the `2>&1` redirection operator.

your_command 2>&1 | tee output.log

Why it works: This redirects file descriptor 2 (stderr) to file descriptor 1 (stdout), effectively merging both streams. The `tee` command then displays this unified output on the terminal and saves it to `output.log`.

Pro-Tip: Use `your_command > output.log 2>&1` to redirect both stdout and stderr to a file without displaying it on the terminal.
