The sudo (SuperUser DO) command is used in Linux-based systems to execute administrative tasks, such as changing permissions or accessing root-level files and directories. When a technician needs to change file or user permissions, they often use chmod or chown with sudo to gain the required privileges.
Option B (chxod): This is a typo. The correct command is chmod, used to change file permissions.
Option C (xv): Not a valid command in Linux related to permissions.
Option D (pwd): Stands for “print working directory,” used to display the current directory, not manage permissions.
