As a group, you may need to make some enhancements to your development server (NOT your stable server!) It needs to be able to run the makepasswd program, which may require installing a package with aptitude. Other modifications may be necessary as well, depending on your solution to this part of the assignment.

Make it owned by the root user and the group. Make it so that any file created in this directory will be owned by the group as well.5.It should do all these things without any interactive input. All input should be provided by the values on the command line when the script is run.
