Quick Tip

Redirecting `stderr` to `stdout` for Unified Logging

Challenge: When running complex commands or scripts, error messages (sent to `stderr`) and normal output (sent to `stdout`) can get mixed up or lost, making it difficult to capture all output for analysis or redirection.

The Solution: Use the `2>&1` redirection operator to merge `stderr` into `stdout`.

your_command &> output.log

Why it works: The `&>` operator is a shortcut that redirects both `stdout` (file descriptor 1) and `stderr` (file descriptor 2) to the specified file. This ensures all output, including errors, is captured in a single log file.

Pro-Tip: You can also achieve the same result with `your_command > output.log 2>&1`. The `2>&1` specifically tells the shell to send file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout).
