Hi,

Copy your script to /sbin/init.d/ directory and set execute permission. Then create symbolic link in the appropriate run level RC directory to this script. For eg. the script name is "myscript.sh" and I want that to run on run level 3. Then I would do the following.

#cp myscript.sh /sbin/init.d
#chmod 755 /sbin/init.d/myscript.sh
#cd /sbin/rc3.d
#ln -s /sbin/init.d/myscript.sh S101myscript.sh (the number 101 is the sequence number, you can change it any number).
#cd /sbin/r2.d
#ln -s /sbin/init.d/myscript.sh K899myscript.sh (the number 899 is the sequence number, you can change it to any number).

remember to test your script before adding to these directories, else your system may not boot correctly.

Good luck
Shahul

You could also check how the inittab file works, this can be handy for things that need to be running from boot time.

Hi:

The whitepaper Torsten cited is probably the best discussion. You can also see a virtual summary in the manpages for 'rc(1M)'. You will note from those manpages that a return code of <4> and greater is defined. This was not described in the original paper.

Two more things.

1. You can prepare a file under /etc/rc.config.d/ to switch on and off the start up scripts.

2. The K and S number should have the sum of 1000. So if the start up file is S911 then the shutdown number should be K089.

Just a remark
don't use or don't start application which are using socket/netstat before
/sbin/rc2.d/S008net.init
