The command chkconfig is used to manipulate the runlevel services in Linux. Runlevels are different operating modes in which a system can run. The command chkconfig allows you to enable or disable services in different runlevels.
In this specific command:
--level ${3}specifies the runlevel at which the change should be made. The value of${3}is a variable that should be replaced with a specific runlevel number.${ntpd}represents the service to be modified. Again, it is a variable that should be replaced with the actual service name.
The command off is used to disable or turn off the specified service at the specified runlevel. This means that the service ${ntpd} will not start automatically when the system boots up in runlevel ${3}.
