newbie - How to run a script?

[Srinivas G.]

Dear All,

I have written a script under Fedora Core 3 with 2.6.9-1.667 kernel
version. Previously I used to run the script in the RPM spec file using
insserv -d /etc/init.d/tifmd where tifmd is my script name. Now I am
unable to find the insserv command under Fedora Core 3. 

What is the equivalent command for insserv command? How to run a script?

Any advice will be greatly helpful to me.

Regards,
Srinivas G
