The following example shows you how to create resources in Puppet using the low-level types and provider method. To run an exec task, use the task command, specifying the command to be executed. This means that you can allow other people access to the code, without access to the sensitive data in that code. This is generally much faster than completely stopping and restarting the process.

Your require parameter is only indicating that the exec resources should be handled before the file resources, not that their "return value" should indicate whether to create the resource or not. Selector expressions. Each resource describes the desired state for some aspect of a system, like a specific service or package. With this, one can define a single default path for the entire configuration. exe -NoProfile -NoLogo . If given a type, a name, and a series of attribute = value pairs, puppet resource will.
