Quick Tip

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

Challenge: When running commands or scripts, standard output (stdout) and standard error (stderr) are often mixed or directed separately, making it difficult to capture all output, especially for logging or debugging purposes.

The Solution: Use `2>&1` to redirect standard error to standard output.

your_command > output.log 2>&1

Why it works: The `2` represents file descriptor 2 (stderr), and `&1` means to redirect it to the same place as file descriptor 1 (stdout). By redirecting stdout to a file (`output.log`), all output, including errors, will be captured in that file.

Pro-Tip: For more complex scenarios where you want to send stdout to one file and stderr to another, you can use `your_command > stdout.log 2> stderr.log`.
