Quick Tip

Tame Your Terminal: Unified Logging with `2>&1`

Challenge: When running commands or scripts that produce both standard output (stdout) and error output (stderr), it’s often useful to capture all of it into a single log file for easier analysis.

The Solution: Use the `2>&1` redirection operator to send stderr to stdout.

your_command &> output.log

Why it works: The `&>` operator is a shorthand for `> output.log 2>&1`. It redirects both stdout (file descriptor 1) and stderr (file descriptor 2) to the specified log file. If you only want to redirect stderr, you would use `your_command 2>&1`.

Pro-Tip: Use `tee` to view output in real-time while also saving it to a file: your_command 2>&1 | tee output.log
