init script type

I have a question about the init script type for slackware 13.37, What type is the init scripts in slackware 13.37?

Part of it looks like BSD and another part looks like System V.

I also noticed that the parameters to run a init script is:

Code:

{start | stop | restart | graceful | graceful-stop}

But there is no 'status' parameter and what dose 'graceful' and 'graceful-stop' mean as perameters?

Are you talking about the scripts in /etc/init.d?

If so, there're

Code:

fubar-trona-/etc/rc.d/init.d: file *

README.functions: ASCII English text

collectl:        POSIX shell script, ASCII text executable

collectl-debian:  POSIX shell script, ASCII text executable

collectl-generic: POSIX shell script, ASCII text executable

collectl-suse:    POSIX shell script, ASCII text executable

functions:        ASCII English text

and the README.functions states:

Code:

fubar-trona-/etc/rc.d/init.d: cat README.functions



If you're reading this in /etc/init.d/, Slackware's real init directory is

/etc/rc.d/.  Maybe you already knew this, but it never hurts to say.  :-)



This script was taken from Fedora (and is presumably licensed under the GPL).

While I don't see Slackware init scripts making much use of it (but use it

if you wish), some third party init scripts (such as for commercial software

designed to run on Red Hat based systems) expect this script and use it in

their own init scripts, so it's a good idea to make it available here.



These functions are provided solely for commercial (or other) software that

expects to find "Red Hat-isms".  I wouldn't use them to write new init

scripts (personally), but if you've had experience with them in the past

and like them, by all means feel free.



It's planned to continue support for them.

Hope this helps some.

Slackware's approach to init-scripts is pretty much a hybrid between the bsd and sysv styles (IMO taking the best parts of both)

I suppose you are speaking about the files in /etc/rc.d

To answer your first question, which seems me to be rather rhetorical, they are of Slackware type :cool:

If you look at some you will see that the main ones (those which end in one digit or letter after the dot) are the "real" init scripts, whose purpose is to change the state of the system (its run level) as a whole. Others are scripts used to start or stop a particular service or set of services and can be run in the course of a change in the run level or independently.

As fot the parameters, they are not the same in every script. To understand why, just look at some of them at random.
