Which command writes stdout to stdout.txt and stderr to stderr.txt?

• A. 2> stderr.txt > stdout.txt
• B. > stdout.txt 2> stderr.txt
• C. &> stdout.txt
• D. > stdout.txt 2> stderr.txt

Answer: (D)

Redirecting stdout and stderr to separate files is done with distinct redirection operators: stdout goes to a file with >, and stderr goes to a file with 2>. When both redirections are applied in the same command, they control where each stream goes for that process. The form that directs stdout to stdout.txt and stderr to stderr.txt is the clear, reliable way to achieve the requirement. Using the combined redirection operator (&>) would send both streams to the same file, which isn’t what’s asked for. The order of the two redirections is not important in this case, but the explicit separation ensures each stream ends up in its own file.
