(b) The file /var/log/wtmp contains the recent login/logout activity for all the users. As this is not an ascii file, you need to use the last command to view the contents. Your supervisor requires a list of everyone who has logged in and out again between 1000 to 1500. Write a minimal Unix command using grep to accomplish this. [10 marks] CourseNana.COM
