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

Challenge: When running commands that produce both standard output (stdout) and standard error (stderr), you might want to capture both into a single log file for easier analysis.

The Solution: Utilize shell redirection to merge stderr into stdout.

your_command > output.log 2>&1

Why it works: The `>` symbol redirects stdout to output.log. The `2>&1` then redirects file descriptor 2 (stderr) to the current location of file descriptor 1 (which has already been redirected to output.log).

Pro-Tip: For even cleaner logging, consider piping the output to `tee` to view it in real-time while also saving it to a file: your_command 2>&1 | tee output.log
