You are asked to set up a Linux system for the Acme company. You will be the administrator and only Acme staff will be given accounts. Acme will need a directory for its shared files. Acme currently has two managers: Stark and Lannister. There are two other workers: Kit and Nicky. There are three important documents: a list of holiday requests (anyone can add their request to this), the current pay scales (only managers can change this), and expansion plans (which is confidential to management). Using this information, you should set up user accounts and demonstrate that individuals (for example, Stark and Kit) have appropriate access to sample files and directories. To test whether your solution is a good one, you will also need to demonstrate the following scenarios: Nicky is the Union rep and must create a union file readable by workers and not by management Nicky is promoted to a manager. Check that the union file can no longer be accessed by Nicky. You should use the command-line interface only. You will need to look up command options to achieve these tasks. Include either screenshots or output from the command line to demonstrate and document your answers. Marks will be awarded as follows: a. creating appropriate accounts for current staff (6 marks) b. creating appropriate sample files and documents (6 marks) c. assigning appropriate permissions (6 marks) d. demonstrating appropriate access for current staff (6 marks) e. demonstrating the new scenarios (6 marks)
