[chef] Re: managing windows services via chef

Well, I got this to work (I think) - more testing now...


only_if 0==`sc query WZCSVC \| find /C /I \"running\"`

I'm trying this approach, but it seems to wait for user input (and then doesn't see the whole command):

    ruby_block "first-search" do
        block do
            puts "the service WZCSV was found"
        end
        action :create
        only_if "sc query WZCSVC \| find /C /I \"running\""
    end   

Is there something wrong with how I've phrased the "only_if portion of this ruby block?

It halts there and when I hit enter, it's as if something was not sent to the "sc" command:

But that all looks healthy - any suggestions?

Hello again all -

First - thanks all for all the really helpful replies to any/all earlier posts. I've been able to move pretty quickly because of the help.

Now I have a tougher question.

I'm trying to work with a windows service for an item that we build and install. 

This means stopping it if it exists, installing it if it doesn't and then starting it if it isn't already running.

I've tried to make the only_if/not_if be a "sc query <servicename>", but I'm seeing mixed results in different windows servers.

On Windows 7, if the service doesn't exist, I get a non-zero (1060) return value, on Windows server 2003 (R2), I get 0 regardless if the service exists or doesn't exist.

I've been thinking about just parsing the output of the "sc query" command versus just relying on the return value, but this is starting to feel kludgy.

Any suggestions?
