Deploying run level script execution

Edit online

Run level scripts allow users to start and stop selected applications while changing the run level.

Put run level scripts in the subdirectory of /etc/rc.d that is specific to the run level:
  • /etc/rc.d/rc2.d
  • /etc/rc.d/rc3.d
  • /etc/rc.d/rc4.d
  • /etc/rc.d/rc5.d
  • /etc/rc.d/rc6.d
  • /etc/rc.d/rc7.d
  • /etc/rc.d/rc8.d
  • /etc/rc.d/rc9.d

The /etc/rc.d/rc will run the scripts it finds in the specified directory when the run level changes - first running the stop application scripts then running the start application scripts.

Note: Scripts beginning with K are stop scripts, while scripts beginning with S are start scripts.
