Quick Tip

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

Challenge: When running commands, especially in scripts or for background processes, you often end up with both standard output (stdout) and standard error (stderr) messages cluttering your terminal or log files. Separating these can be cumbersome.

The Solution: Redirect both standard error and standard output to a single destination.

command 2>&1 | tee output.log

Why it works: The `2>&1` syntax tells the shell to redirect file descriptor 2 (stderr) to file descriptor 1 (stdout). By piping this combined output to `tee`, you can view it on the terminal and simultaneously save it to `output.log`.

Pro-Tip: For background processes where you only want to log output, simply use `command > output.log 2>&1 &`.
