Quick Tip

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

Challenge: When running commands or scripts that produce both standard output (stdout) and error messages (stderr), it can be difficult to track and analyze them together. You might want to capture both in a single log file.

The Solution: Use shell redirection to combine stderr with stdout.

command > output.log 2>&1

Why it works: The `>` operator redirects stdout to `output.log`. The `2>&1` part is the key: `2` represents stderr, and `&1` represents stdout. This redirection tells the shell to send file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout), effectively merging them.

Pro-Tip: You can also use `&>` as a shorthand for `> … 2>&1` in Bash (e.g., `command &> output.log`).
