Managing Users, Groups, and Permissions

Note:

• All tasks should be performed as the root user.
• The root user can be accessed by running sudo -i (no password is required)

You work as a Linux administrator for a small IT company, and have been tasked with setting up a server to provide collaboration between the various departments involved in the development and, ultimately, the deployment of the product (please pay close attention to the Note section).

First, you will need to create a new group in charge of quality assurance, named qa with a group ID of 1301, and rename the existing group, dev, to the name devops. Once created, you will need to add two new users — sam and steve. sam should be created without a home directory and with qa and devops as supplementary groups. steve should be created with a user ID of 1250 and his main group should be qa. Then, you will need to update two existing users — john and sally. john's main group should be updated to qa and his home directory should be /home/associate. sally's user ID should be updated to 1255 and qa should be added as a supplementary group.

Now that the users have been added and updated, changes need to be made to the team folders. The folder /usr/local/share/staging/ and all its contents should be owned by sally and the qa group, and the folder /usr/local/share/production/ and its contents should be owned by the devops group.

Next, the folders and their contents need to be updated to provide appropriate access and security. Using octal mode permissions, update /usr/local/share/staging to read/write/execute for owner, read/write/execute for group, and read/execute for other; and update /usr/local/share/production/deploy.sh to have read/write/execute on user, read on group, and 0 permissions for other. Then, using symbolic mode permissions, update /usr/local/share/production/ to read/write/execute for owner, read/write/execute for group, and 0 permissions for other; and add write and execute permissions for group to /usr/local/share/staging/report.sh.

Finally, you will need to remove two users who are no longer with company —benedict and arnold— as well as a group that is no longer in use, test.
