The document summarizes a Linux administration lab experiment performed by the student. The aim was to create a new user named TOM, add them to a secondary group, create a file and modify its permissions and ACLs. Key tasks included creating the TOM user, adding them to the GRP secondary group, creating a file with text content and storing a command to display its ACL, and using commands to change the file's ACL configuration and grant the TOM user permission to access the file contents. The student was evaluated based on demonstration and performance, a worksheet, and a post-lab quiz.
