Why not start from the skeleton, change the start and stop sections to do

(log files normally would go to /var/log/, but since your playing, I
think /tmp/ is better)

Dear Leendert,
I was playing these days with it, understood a lot, but again there is
some small problems I have.

Here what I have done:
In the skeleton I just changed the appropriate parts to

Here's a extremely minimalistic 'skeleton', stripped from comments:

# Short-Description: FOO XYZ daemon providing ZYX
# Description: Start FOO to allow XY and provide YZ
# continued on second line by '#<TAB>'
# should contain enough info for the runlevel editor

### END INIT INFO

I am a newbie and got a very little experience with shell scripting,

Hmm, I assumed you know a bit of shell-script programming.

However, if you're a programmer, you might learn it quickly (you know best if
you could).

maybe I should leave this for a better times?

Well, you learning curve just got a bit steeper... ;) You might as well add
'man bash' to your RTFM list. But there are some shell-scripting tutorials on
the net. However I can't recommend any, because I don't know any. ;)

Here's a starting point: http://en.wikipedia.org/wiki/Bash (I like Wikipedia
more and more...). There are some links at the bottom that might interest
you.

Cheers,

Leen
