I got this question by my college professor while I was bunking the class.

The above asked question is from Displaying and Creating Files: cat Command in section Handling Ordinary Files of Unix

Answer 1

Correct option is (b) -c

Explanation: In case if there is a strict requirement that touch command should not create a new file, we can use the -c option with it. Else if the file already exists then it will do nothing.
