Puppet users - Dec 2010 - more than one subscription

Hi

I need to run a command if any one of a number of files change.  I can
handle this with having an exec and a subscribe clause listing the
dependencies but I want the command to be run once per run, i.e. after
all the possible updates have happened.

I note stages can only be used within a class so do I have to have a
separate class for my command?

That is exactly what puppet will do.

    exec {''/bin/echo "executed" >> /tmp/list'':
      refreshonly => true,
      subscribe   => [
        Exec[''first''],
        Exec[''second''],
      ],
    }

    exec {''first'': command => ''/bin/echo
first''}
    exec {''second'': command =>''/bin/echo
second''}

If you''re running this you will get
<Resource> Triggered ''refresh'' from 2 events and you
will only have one
line in /tmp/list
