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 these two streams of information separately. This is especially problematic when you want to capture all output to a single log file.

The Solution: Redirect both standard output and standard error to a single destination using the `2>&1` construct.

your_command &> combined_output.log

Why it works: The `&>` operator is a shorthand for `>` (redirect stdout) and `2>&1` (redirect stderr to stdout). This ensures that both types of output are written to the specified file, making log analysis much cleaner.

Pro-Tip: For older shells that might not support `&>`, you can achieve the same result with your_command > combined_output.log 2>&1.
