LPIC-1 Exam 101 (Linux Administrator) — Question 1

Which of the following commands will send output from the program myapp to both standard output (stdout) and the file file1.log?

Answer options

• A. cat < myapp | cat > file1.log
• B. myapp 0>&1 | cat > file1.log
• C. myapp | cat > file1.log
• D. myapp | tee file1.log
• E. tee myapp file1.log

Correct answer: D

Explanation

The correct answer is D because the 'tee' command allows you to send output to both the terminal and a file simultaneously. The other options either do not properly redirect output to both locations or are incorrectly using commands that do not achieve the desired output behavior.
