You now need to write a script for user maintenance. Write a script that will perform the following tasks: Prompt the system administrator for all valid input parameters Generate a menu to ask which task is needed to be performed Create a UNIX group Drop a UNIX group Create a user Drop a user Note that as part of the Create User section, a UNIX group many be identified that does not already exist, so that group will need to be created as part of the process. A third script that you need to write will kill all of the processes associated with a user. The following are the requirements: Prompt the system administrator for the target user name List the running processes for that user Confirm with the system administrator before killing the processes Kill the processes after confirmation It is very important to note with this task that you should only kill processes for a user and his or her running processes; do not arbitrarily kill running daemons. Include a discussion about the difference between user processes and daemons. What are daemons, and what are they used for? What are the consequences of killing a daemon using this script?
