Quick Tip
Taming Terminal Noise: Unified Logging with `2>&1`
Challenge: When running commands or scripts that produce both standard output (stdout) and standard error (stderr), it can be difficult to manage and analyze the combined output. Often, you want to redirect both to a single log file for easier review.
The Solution: Use the `2>&1` redirection to merge stderr into stdout.
your_command &> output.log
Why it works: The `&>` operator is a shorthand that redirects both stdout and stderr to the specified file. This is a concise way to achieve unified logging for your commands.
Pro-Tip: For more granular control, you can use `your_command > output.log 2>&1`. This explicitly redirects stdout to `output.log` and then redirects stderr (file descriptor 2) to wherever stdout is currently pointing (file descriptor 1), effectively merging them.
