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 cumbersome to manage them separately, especially when you want to redirect both to a single file for logging or analysis.

The Solution: You can unify both stdout and stderr into a single stream by redirecting stderr to stdout using the `2>&1` syntax.

your_command > output.log 2>&1

Why it works: File descriptor 1 represents stdout and file descriptor 2 represents stderr. By using `2>&1`, you’re telling the shell to send the contents of file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout), effectively merging them.

Pro-Tip: For simple commands, you can often use `&> output.log` as a shorthand in many shells (like Bash) which achieves the same result of redirecting both stdout and stderr to the specified file.
