Look in /sbin/init.d. There is a template file there. Copy it and adapt it to your needs.

Let's suppose that your script is called 'doit' and that it need to start in run level 3 and stop in run level 2.

You would create the symbolic links
ln -s /sbin/init.d/doit /sbin/rc3.d/S900doit
ln -s /sbin/init.d/doit /sbin/rc2.d/K100doit

By convent the Sxxx and Kyyy values should sum to 1000 because that tends to correctly order the startup and stop routines.

Man rc for details.

It's just a little bit more complicated than you state it.

You determine the runlevel at which the process should run. If that doesn't matter, use /etc/rc.local and add this line to /etc/inittab:

lcl:3456:once:/etc/rc.local

/etc/rc.locat will than be executed only once when init level 3, 4, 5, or 6 is entered. Just include the levels there you need.

If the sequence is important (depends on what parts of the boot process is done, and which part not (yet), you have to go dig in /sbin/init.d and /sbin/rc#.d (where # is the runlevel you want to influence

You need to put it in /sbin/init.d and then create run links and stop links. The links will be put in rc dirs depending upon which run level you want it to start.

Refer /sbin/init.d/template file.

Plan B (and not suggested): You can also create an entry in /etc/inittab.

Attached find the HP doc we use for this which includes a function to test.

All input so far should get you the desired results.

Best of luck.
