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

Challenge: When running commands or scripts, standard error (stderr) messages can clutter your output, making it hard to distinguish actual results from error indicators, especially when piping output to other commands or redirecting to files.

The Solution: Use the `2>&1` redirection operator to merge stderr into stdout, allowing for unified handling of both streams.

your_command ... > output.log 2>&1

Why it works: File descriptor 1 represents standard output (stdout), and file descriptor 2 represents standard error (stderr). The `2>&1` syntax redirects file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout).

Pro-Tip: For a cleaner approach to log aggregation, consider using `tee` to both display output on the terminal and save it to a file simultaneously: your_command ... 2>&1 | tee output.log
