What is the purpose of the sudo command in Linux?

The sudo command in Linux is used to execute commands with administrative (root) privileges. It allows authorized users to run specific commands as the superuser or another user, as specified by the system's security policy. This is particularly useful for performing tasks that require elevated permissions, such as installing software, modifying system configurations, or managing user accounts. By using sudo, users can perform these actions without needing to log in as the root user directly, enhancing security and accountability.
