Quick Tip

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

Challenge: When running commands or scripts, you often want to capture both standard output (stdout) and standard error (stderr) into a single log file to have a complete picture of what happened.

The Solution: Use the `2>&1` redirection operator.

your_command > output.log 2>&1

Why it works: The `>` operator redirects stdout (file descriptor 1) to `output.log`. The `2>&1` then redirects stderr (file descriptor 2) to wherever stdout is currently being redirected (which is `output.log`).

Pro-Tip: If you want to append to the log file instead of overwriting it, use `>>` for stdout: your_command >> output.log 2>&1
