[Techtalk] killproc

[Maria McKinley]

Hi there,

I run debian, and I have a script I want to stick in /etc/init.d/, but 
it calls the function killproc, which does not seem to be available in 
the debian package system. Does anyone know how killproc works, and how 
I can re-write the line using kill?

killproc $MATHLM_BINARY 15

This same script calls . /etc/init.d/functions, which looks like it is a 
redhat thing, and commenting it out seems to have no ill effect.

Finally, this line:
[ ${NETWORKING} = "no" ] && exit 1

causes this error:

/etc/init.d/mathlm: line 24: [: =: unary operator expected

Any ideas on any of these issues? I've attached the script, in case that 
makes life easier.

thanks,
maria
