Quick Tip

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

Challenge: When running commands or scripts, error messages (stderr) often get mixed with normal output (stdout), making log analysis and debugging difficult.

The Solution: Redirect both stderr and stdout to a single file or stream using the `2>&1` syntax.

your_command &> output.log # or your_command > output.log 2>&1

Why it works: File descriptor 1 represents stdout, and file descriptor 2 represents stderr. `2>&1` tells the shell to redirect file descriptor 2 to where file descriptor 1 is currently pointing.

Pro-Tip: Use `&>` for a more concise redirection of both streams.
