Linux Foundation Certified System Administrator (LFCS) — Question 123

What happens after issuing the command vi without any additional parameters?

Answer options

• A. vi starts and loads the last file used and moves the cursor to the position where vi was when it last exited.
• B. vi starts and requires the user to explicitly either create a new or load an existing file.
• C. vi exits with an error message as it cannot be invoked without a file name to operate on.
• D. vi starts in command mode and opens a new empty file.
• E. vi starts and opens a new file which is filled with the content of the vi buffer if the buffer contains text.

Correct answer: D

Explanation

The correct answer is D because when vi is started without any parameters, it defaults to opening a new empty file in command mode. Options A, B, and E are incorrect as they describe behaviors that do not occur when no file is specified, and option C is also wrong because vi does not exit with an error in this scenario.
