update-rc.d

update-rc.d updates the System V style init script links /etc/rcrunlevel.d/NNname whose target is the script /etc/init.d/name. These links are run by init when it changes runlevels; they are generally used to start and stop system services such as daemons. runlevel is one of the runlevels supported by init, namely, 0123456789S, and NN is the two-digit sequence number that determines where in the sequence init will run the scripts.
