The given command is using the "sudo" (Superuser Do) command, which is used in Linux and Unix-like operating systems to perform administrative tasks with elevated privileges. It allows regular users to execute commands as the superuser or another user with administrative rights.

The "extrace" command appears to be a typo or a custom command, as there is no standard Linux command by that name. Assuming it is a custom command or a placeholder, the command is trying to execute the value of the "${command}" variable with sudo privileges.

The "${command}" is likely a placeholder for a specific command that needs to be executed with administrative privileges. When running this actual command, you would substitute "${command}" with the desired command. For example:

sudo extrace ls

In this example, the "ls" command would be executed with superuser privileges, allowing access to system directories and files that regular users might not have permission to view.

Without more context or the actual value of "${command}", it is not possible to provide a more specific explanation of how the command is executed or what it does.
