NOTE: In process to document and format.

* The commands and wizards are basic operations that it will be run by the PXE OpenGnSys client.
* The difference between a command and a wizard is in the amount of information required by the user or it is shown before to running. 
* Both share the property of: 
  * To monitor - To see the result of the operation from classrooms->$SCOPE->actions queue option.
  * To store or add the operation as a procedure and/or task. 

* Before to explain the task and procedures it is necesary:
  * Scope definition. 
     * Application scope of an action is: organizational unit, classrooms group, classrooms, computers group, computer.
     * Scopes are structured in hierarchical mode. 

* The tasks and procedures are used to group the basic operations (commands and wizards):
  * Procedures: 
     * To be included as option in the clients menus. 
     * To be included as init operation of the OpenGnSys clients (autoexec)
     * From web console as quick operation on a grouping.
  * Tasks:
     * To be used on a program mode from the tasks manager.
     * To be used as element on the clients menu. So, you can have a private menu only on a computer, but the operation can be apply on a scope.

* The procedure scope is similar to commands and wizards, in other words it is applied to the scope where it is run in a given time.

* A command, wizard and procedures, depending of the scope level where it is run, it will be applied to all children scopes.
  * For this reason, it is recommended to use a computer group, for execute puntual tasks over a number of computers.
  * The grouping or change the computer group can be doing:
    * One by one: on a computer scope, choose option "move" and then on the desired scope, "place".
    * Multiple selection from "Relocate computers" option of a classroom scope.  See ticket:387
 
* Depending on the action to run, the operation will be run on all computers currently on (PXE og client), and others will be programmed. So that if a computer is off, at the time of turn on the operation is carried out.

* All these operations are running in the PXE OpenGnSys client and make use of:
  * InterfaceAdm
  * Scripts
  * API
 
We can evaluate any tasks and the running process in the client (InterfaceAdm->Scripts->API) from the text console which provides the ogClient-admin or remotely by ssh or any management cluster tool with ssh.
