Quick Tip

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

Challenge: When running complex commands or scripts, standard output (stdout) and standard error (stderr) can get mixed up, making it difficult to analyze logs or troubleshoot issues effectively. You want to capture both in a single, manageable stream.

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

your_command > output.log 2&>1

Why it works: The `>` redirects stdout (file descriptor 1) to `output.log`. The `2>&1` then tells the shell to redirect file descriptor 2 (stderr) to the same place as file descriptor 1, effectively merging both streams.

Pro-Tip: You can also use `>&1` as a shorthand for `> output.log 2&>1` if you’re redirecting to a file, or simply `2>&1` if you’re piping the output to another command.
