Step 18. Based on the mask value from step 17, what permissions would all new files that are created in this shell have?

Lab 9.2 Managing Special Permissions

Scenario 1: You are concerned about SUID permissions on this system. Start by running the command to find all files that have SUID permissions set. Then change the newgrp command so it is not a SUID file.

Scenario 2: Three users need to share files on the system, but no other user can have access to these files. Create user accounts for sophia, olivia, and emma, using default values for account parameters. Create a common group named shared, which will be used to allow these three users to share files with each other. Finally, create a directory named /home/shared for only these three users to access and to also automatically give group ownership of all new files to the shared group.
