Exercise 1 - Create and Manage Special Purpose and Limited Accounts

In an operating system, you can have one or more users. Initially, single user operating system like DOS could have only one user. This changed with the advent of multiuser operating system, such as Linux. Each user has a different profile and can be granted a different level of access in the operating system.

Linux enables you to create special purpose, which are limited accounts. These accounts can be useful when you want to limit the rights of the user such that they are able to access only a very limited amount of data and then perform only specified operations on the same. For example, you can create a special account where the user might have read-only permissions and that too only on the home directory. These permissions override any of the permissions granted to the individual files.
