Quick Tip

Taming 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 both simultaneously, especially when piping them to other commands or redirecting them to files.

The Solution: You can redirect both stderr and stdout to the same destination using the `2>&1` redirection operator.

your_command 2>&1 | tee output.log

Why it works: The `2>&1` tells the shell to redirect file descriptor 2 (stderr) to the same place as file descriptor 1 (stdout). In this example, `tee` then receives both streams, prints them to the console, and saves them to `output.log`.

Pro-Tip: To discard error messages but keep standard output, simply redirect stderr to `/dev/null`: your_command 2>/dev/null.
