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

Challenge: When running commands or scripts, error messages (stderr) often appear separately from standard output (stdout), making it difficult to capture and analyze all output in a single log file.

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

your_command > output.log 2>&1

Why it works: File descriptor 1 represents stdout and file descriptor 2 represents stderr. The `>` redirects stdout, and `2>&1` redirects stderr to where stdout is currently being sent.

Pro-Tip: You can use this with `tee` to see output on screen while also logging it: `your_command 2>&1 | tee output.log`
