Quick Tip

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

Challenge: When running commands or scripts that produce both standard output (stdout) and error output (stderr), it can be difficult to manage and analyze the combined results, especially when redirecting output to a file.

The Solution: Use the shell redirection `2>&1` to combine stderr into stdout, allowing you to redirect both streams to a single destination.

your_command &> output.log

Why it works: The `&>` redirection operator is a shorthand that redirects both stdout and stderr to the specified file. This is equivalent to `your_command > output.log 2>&1`.

Pro-Tip: To redirect only stderr to stdout, while still letting stdout go to its default location, use `2>&1` on its own within a pipe: `your_command 2>&1 | another_command`.
