Create a script in /etc/init.d and make a symbolic link to it in the rc

So just chuck it in anywhere? Does it matter who owns the file? Should it be
the user? root?
For example, the /etc/init.d/foo.sh may be:
#!/bin/bash
cd /foo
/foo/make_something.sh
If you want this script to run in runlevel 2, then you can:
ln -s /etc/init.d/foo.sh /etc/rc2.d/S99foo
So I'd make the file, put it somewhere in /etc/init.d then symlink it to
/etc/rc2.d ? Seems kinda... random to me.
In the other hand, at any moment you can now the runlevel in what you are
just
typing:
who -r
Have a look at /etc/init.d scripts, they are self explanatory.
There's no directory in /etc/init.d called scripts. I know nothing about
shell scripting and many of you seem to assume that I know what I'm doing
here. I'm a Mac guy, command lines still scare me.
Also, have a look at "man init"

/etc/init.d/ is where all of the startup scripts should live. /etc/rc2.d
for example, holds all the scripts that get started up in run level 2,
which is the defult run level for debian, so it may seem random, but
really its not. It's just easier to have the scripts in /etc/init.d/ and
link them to all the differnt run levels if you need them. The S99 , says
start and the init process executes each script in a numerical order, if
you look in /etc/rc2.d you will see a which order things get started.
Usually for user added stuff 99 is good.
So first thing you need to do, it make the script so that it runs the way
you want. You also have to remember that scripts get ran as root at start
up too. But you need to have your command ran as fox right? so:
su -c "command" fox
that will run the command you want as fox, through su.
for example:
#!/bin/sh
PATH=/bin:/usr/bin
cd /usr/local/myapp/
su -c "./myappp " fox
that, if ran throught the init process would result the script cd'ing into
the directory /usr/local/myapp/ and running myapp as fox..
once you have your script working the way you want it to, place it in
/etc/init.d then link it as above.
Also, take a look at /etc/rc2.d/README
