Need help to display these three outputs step by step please. (Linux question)

The mkdir (make directory: Sobell, page 90) utility creates a directory. Use mkdir to create a directory named two as a subdirectory of your home directory. Use file to make sure two exists and is a directory. An absolute pathname (Sobell, page 88) starts with a slash and traces a path from the root directory to the file identified by the pathname. As step 1 shows, the pwd command displays the absolute pathname of the working directory. When you call cd with an argument of the name of a directory, it makes that directory the working directory. Use cd to make two the working and then give a pwd command to confirm the name of the working directory. List all of the directories and files that start with the letter 'g' in the /etc directory. Show the command to display only those results
