Quick Tip

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

Challenge: When running commands or scripts, you often have both standard output (stdout) and standard error (stderr) messages. It can be cumbersome to manage these separate streams, especially when you want to capture all output into a single log file.

The Solution: Redirect both standard output and standard error to a single file using the `2>&1` redirection operator.

your_command_here > output.log 2>&1

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

Pro-Tip: For appending to an existing log file instead of overwriting, use `>>` for stdout: your_command_here >> output.log 2>&1
